Abstract

 

OBJECTIVE:

 

To evaluate the diagnostic performances of CT and MRI in patients with lumbar intervertebral disc herniation through the Meta analytical method.

 

METHOD:

 

The relevant English and Chinese articles published between 1980 and 2010 were searched in PubMed, Medline, Ovid database, Cochrane library and Chinese Periodical Web. According to the criteria for diagnostic researches published by Cochrane Method Group on Screening and Diagnostic Tests, each article was critically appraised and screened with regards to the absolute numbers of true-positive, false-negative, true-negative and false-positive. Statistical analysis was performed by the Meta-Disc version 1.4, SPSS 13.0 and Comprehensive Meta-analysis version II. Heterogeneity was tested and publication bias analyzed. And the pooled weighted sensitivity and specificity and the corresponding 95%CI were calculated. The summary receiver operating characteristic (SROC) curve was performed and the area under the curve (AUC) calculated to summarize and evaluate the diagnostic efficiency of CT and MRI in lumbar intervertebral disc herniation. Finally a sensitivity analysis was performed.

 

RESULTS:

 

According to the criteria of internalization, 9 articles were included. Among them, the themes were CT (n = 3), MRI (n = 3) and CT & MRI (n = 3). Eight was prospectively studied and one retrospectively. At the diagnosis of lumbar intervertebral disc herniation, the pooled weighted sensibility and specificity and 95% confidence interval and area under SROC curve for CT to the lumbar intervertebral disc herniation was 0.73 (0.68 – 0.77), 0.78 (0.72 – 0.82) and 83.5% respectively. The MRI was 0.88 (0.83 – 0.91), 0.79 (0.71 – 0.87) and 88.8% respectively. There was statistically significant difference in the pooled weighted sensibility (P < 0.05); No statistically significant difference was found in the pooled weighted specificity (P > 0.05); And there was statistically significant difference in the AUC curve (P < 0.05).

 

CONCLUSION:

 

After a meta-analysis of the diagnostic value of CT and MRI for the lumbar intervertebral disc herniation, MRI is more accurate than CT in the diagnosis of lumbar intervertebral disc herniation.

Abstract

 

BACKGROUND:

 

Low-back pain with leg pain (sciatica) may be caused by a herniated intervertebral disc exerting pressure on the nerve root. Most patients will respond to conservative treatment, but in carefully selected patients, surgical discectomy may provide faster relief of symptoms. Primary care clinicians use patient history and physical examination to evaluate the likelihood of disc herniation and select patients for further imaging and possible surgery.

 

OBJECTIVES:

 

(1) To assess the performance of tests performed during physical examination (alone or in combination) to identify radiculopathy due to lower lumbar disc herniation in patients with low-back pain and sciatica;(2) To assess the influence of sources of heterogeneity on diagnostic performance.

 

SEARCH STRATEGY:

 

We searched electronic databases for primary studies: PubMed (includes MEDLINE), EMBASE, and CINAHL, and (systematic) reviews: PubMed and Medion (all from earliest until 30 April 2008), and checked references of retrieved articles.

 

SELECTION CRITERIA:

 

We considered studies if they compared the results of tests performed during physical examination on patients with back pain with those of diagnostic imaging (MRI, CT, myelography) or findings at surgery.

 

DATA COLLECTION AND ANALYSIS:

 

Two review authors assessed the quality of each publication with the QUADAS tool, and extracted details on patient and study design characteristics, index tests and reference standard, and the diagnostic two-by-two table. We presented information on sensitivities and specificities with 95% confidence intervals (95% CI) for all aspects of physical examination. Pooled estimates of sensitivity and specificity were computed for subsets of studies showing sufficient clinical and statistical homogeneity.

 

MAIN RESULTS:

 

We included 16 cohort studies (median N = 126, range 71 to 2504) and three case control studies (38 to100 cases). Only one study was carried out in a primary care population. When used in isolation, diagnostic performance of most physical tests (scoliosis, paresis or muscle weakness, muscle wasting, impaired reflexes, sensory deficits) was poor. Some tests (forward flexion, hyper-extension test, and slump test) performed slightly better, but the number of studies was small. In the one primary care study, most tests showed higher specificity and lower sensitivity compared to other settings.Most studies assessed the Straight Leg Raising (SLR) test. In surgical populations, characterized by a high prevalence of disc herniation (58% to 98%), the SLR showed high sensitivity (pooled estimate 0.92, 95% CI: 0.87 to 0.95) with widely varying specificity (0.10 to 1.00, pooled estimate 0.28, 95% CI: 0.18 to 0.40). Results of studies using imaging showed more heterogeneity and poorer sensitivity. The crossed SLR showed high specificity (pooled estimate 0.90, 95% CI: 0.85 to 0.94) with consistently low sensitivity (pooled estimate 0.28, 95% CI: 0.22 to 0.35).Combining positive test results increased the specificity of physical tests, but few studies presented data on test combinations.

 

AUTHORS’ CONCLUSIONS:

 

When used in isolation, current evidence indicates poor diagnostic performance of most physical tests used to identify lumbar disc herniation. However, most findings arise from surgical populations and may not apply to primary care or non-selected populations. Better performance may be obtained when tests are combined.

Abstract

 

Lumbar disc herniation has a high prevalence and strong social-medical impact. Patients suffer from lower back pain that radiates from the spine. Loss of sensation or paresis adds to the clinical picture. The diagnosis should be confirmed by imaging in patients considered for surgery. High remission rates initially warrant conservative treatment (adequate analgesia and physiotherapy) in many patients. If this treatment does not lead to significant alleviation within 5-8 weeks, surgery should be performed to reduce the risk of chronic nerve affection. Posterior interlaminar fenestration is the intervention primarily conducted for this diagnosis. A relapse in the same region occurs in up to 10% of patients after months through years, which sometimes necessitates a reoperation if symptoms are pertinent.

Abstract

 

STUDY DESIGN:

 

Systematic review.

 

OBJECTIVE:

 

To assess the effectiveness of interventions for treating cervical disc herniation.

 

SUMMARY OF BACKGROUND DATA:

 

Cervical disc herniation is 1 of the 23 specific disorders included in the CANS (Complaints of the Arm, Neck, and/or Shoulder) model. Treatment options range from conservative to surgical, but evidence for the effectiveness of these interventions is not yet well documented.

 

METHODS:

 

The Cochrane Library, MEDLINE, EMBASE, PEDro, and CINAHL were searched for relevant systematic reviews and randomized clinical trials (RCTs) up to February 2009. Two reviewers independently selected relevant studies, assessed the methodological quality, and extracted data.

 

RESULTS:

 

Pooling of the data was not possible; thus, a best-evidence synthesis was used to summarize the results. Of the 11 RCTs included, 1 compared conservative with surgical intervention, and 10 compared various surgical interventions. No evidence was found for the effectiveness of conservative treatment (nonsteroidal anti-inflammatory drugs, cortisonics, and physical therapy) compared with percutaneous nucleoplasty. Moderate evidence was found for the effectiveness of anterior cervical discectomy with fusion (ACDF) using a titanium cage compared with ACDF using polymethyl methacrylate, and for BRYAN cervical disc (Medtronic Sofamor Danek, Memphis, TN) prostheses compared with ACDF using allograft bone and plating. No outcomes regarding adjacent-level disease were reported. There is conflicting evidence for the effectiveness of ACD compared with ACDF. Only limited or no evidence was found for the other surgical interventions.

 

CONCLUSION:

 

No evidence for effectiveness of conservative treatment compared with surgery was found. Although there is moderate evidence for the effectiveness of some surgical interventions, no unequivocal evidence for the superiority of 1 particular surgical treatment was found. Worldwide, most patients receive supplementary implants; however, cervical discectomy without graft may be preferred because of similar outcomes, lower costs, and possibly a lower risk of adjacent-level disease. More high-quality RCTs using validated outcome measures (including adjacent level disease) are needed.

Abstract

 

BACKGROUND:

 

Low back pain (LBP) is one of the most common and important health problems affecting the population worldwide and remains mostly unsolved. Ozone therapy has emerged as an additional treatment method. Questions persist concerning its clinical efficacy.

 

OBJECTIVE:

 

The purpose of our study was to evaluate the therapeutic results of percutaneous injection of ozone for low back pain secondary to disc herniation.

 

STUDY DESIGN:

 

A systematic review and meta-analysis of randomized controlled trials.

 

METHODS:

 

A comprehensive literature search was conducted using all electronic databases from 1966 through September 2011. The quality of individual articles was assessed based on the modified Cochrane review criteria for randomized trials and criteria from the Agency for Healthcare Research and Quality. OUTCOME PARAMETERS: The outcome measure was short-term pain relief of at least 6 months or long-term pain relief of more than 6 months.

 

RESULTS:

 

Eight observational studies were included in the systematic review and 4 randomized trials in the meta-analysis. The indicated level of evidence for long-term pain relief was II-3 for ozone therapy applied intradiscally and II-1 for ozone therapy applied paravertebrally. The grading of recommendation was 1C for intradiscal ozone therapy and 1B for paravertebral ozone therapy.

 

LIMITATIONS:

 

The main limitations of this review are the lack of precise diagnosis and the frequent use of mixed therapeutic agents. The meta-analysis included mainly active-control trials. No placebo-controlled trial was found.

 

CONCLUSIONS:

 

Ozone therapy appears to yield positive results and low morbidity rates when applied percutaneously for the treatment of chronic low back pain.

Abstract

 

OBJECTIVE:

 

To evaluate the efficacy and safety of the manipulative treatment on lumbar disc herniation and analyze the current status of clinical studies.

 

METHODS:

 

The PubMed, OVID, Cochrane Library, CBM – disc database, CNKI database and VIP Database were retrieved, and 832 literatures on manipulative treatment for lumbar disc herniation were collected, in which 8 articles met the inclusion criteria. Cochrane systematic review was used to evaluate the quality; and RevMan 4.2 was used for Meta Analysis of Literatures.

 

RESULTS:

 

There were total 911 patients in the 8 articles. The summary OR for the combined cure rate of the 8 articles was 3.65, and the 95% CI was [2.15, 6.20]. The summary OR for the combined efficiency was 3.56, and the 95% CI was [2.35, 5.38]. The cure rate and effective rate of the patients in manipulative group were superior to those of patients treated with other methods such as drugs, traction, acupuncture, microwave thermotherapy (all the methods were called as “other therapies”).

 

CONCLUSION:

 

This study shows that manipulative treatment on lumbar disc herniation is safe, effective, and both cure rate and the effective rate is better than other therapies. But the number of documents is limited and the quality is not very high, and the conclusion is still uncertain, high-quality evidence is needed to be further validated.

Abstract

 

The effectiveness of surgery in patients with sciatica due to lumbar disc herniations is not without dispute. The goal of this study was to assess the effects of surgery versus conservative therapy (including epidural injections) for patients with sciatica due to lumbar disc herniation. A comprehensive search was conducted in MEDLINE, EMBASE, CINAHL, CENTRAL, and PEDro up to October 2009. Randomised controlled trials of adults with lumbar radicular pain, which evaluated at least one clinically relevant outcome measure (pain, functional status, perceived recovery, lost days of work) were included. Two authors assessed risk of bias according to Cochrane criteria and extracted the data. In total, five studies were identified, two of which with a low risk of bias. One study compared early surgery with prolonged conservative care followed by surgery if needed; three studies compared surgery with usual conservative care, and one study compared surgery with epidural injections. Data were not pooled because of clinical heterogeneity and poor reporting of data. One large low-risk-of-bias trial demonstrated that early surgery in patients with 6-12 weeks of radicular pain leads to faster pain relief when compared with prolonged conservative treatment, but there were no differences after 1 and 2 years. Another large low-risk-of-bias trial between surgery and usual conservative care found no statistically significant differences on any of the primary outcome measures after 1 and 2 years. Future studies should evaluate who benefits more from surgery and who from conservative care.

Back Pain: Surgery Vs. Non-Surgical Options

Summary:  Just went through the literature again looking for back pain and long term outcomes for surgery vs. nonsurgical treatment.  Can we just say that the studies will never be done?  Just finding long term follow up on patients after back surgery means I need to look outside the U.S. The short answer is that around 15% of patients will need another back surgery in ten years (based on one small study).  But patients with larger areas of involvement are more than five times more likely to need another surgery.  Personally, I’ve never seen a back where the whole back wasn’t involved to some extent.  It may not show up on the scans, but when one area is in crisis, the rest of the back accommodates the wounded part.

Department of Radiology, Section of Neuroradiology, University Hospital of Northern Sweden, 90185, Umeå, Sweden. pdetlic@gmail.com

Abstract

BACKGROUND CONTEXT: Intradural disc herniation is relatively rare complication of the spinal degenerative process that occurs most frequently in the lumbar part of the spine. Both myelographic and magnetic resonance features of this entity have been described, and the mechanism of intradural herniation has already been proposed and generally accepted. In this article, we present a case of spontaneous resorption of an intradural, fragmented intervertebral disc. Spontaneous resorption of intradural disc fragments has not been previously reported.

PURPOSE: To discuss a possible mechanism of spontaneous resorption of the subdural disc fragments.

STUDY DESIGN: Case report and literature review.

METHODS: Radiological follow-up of a 46-year-old man with the intradural herniation of disc fragments.

CONCLUSION: The reaction generated by the meninges might lead to the complete resorption of intrathecally localized disc fragments.

Abstract

The goal of this article is to report our experience on intradural lumbar disc herniation, consider the causes of this pathology, and analyze it from clinical, diagnostic, and therapeutic perspectives with a particular emphasis on the role of MRI in preoperative diagnosis. We analyzed nine patients treated surgically for intradural lumbar disc hernia. All of them underwent surgery, and hemilaminectomy was performed. In six cases, the diagnosis of intradural herniation was definitive and, in the three remaining, it was confirmed at surgery. In five cases, CT (with no contrast medium) of the lumbar area revealed disc herniation, but none could it confirm its intradural location. Myelography was performed in two cases but also could not prove intradural extrusion. Magnetic resonance imaging study was used in four cases. In five, the postoperative outcome has been excellent. Patients 6 and 9 recovered anal function postoperatively; patient 6 suffered from occasional and mild micturition urgency. The three patients previously operated (1, 2, 7) showed good outcome. Presently, we believe that radiologic diagnosis of intradural herniation is possible in carefully selected patients, thanks to MRI with gadolinium.

Pain Management Center of Paducah, Paducah, KY, USA. drlm@thepainmd.com

Abstract

BACKGROUND: Lumbar disc prolapse, protrusion, or extrusion account for less than 5% of all low back problems, but are the most common causes of nerve root pain and surgical interventions. The primary rationale for any form of surgery for disc prolapse is to relieve nerve root irritation or compression due to herniated disc material. The primary modality of treatment continues to be either open or microdiscectomy, but several alternative techniques including nucleoplasty, automated percutaneous discectomy, and laser discectomy have been described. There is a paucity of evidence for all decompression techniques, specifically alternative techniques including nucleoplasty.

STUDY DESIGN: A systematic review of the literature.

OBJECTIVE: To determine the effectiveness of mechanical lumbar disc decompression with nucleoplasty.

METHODS: A comprehensive evaluation of the literature relating to mechanical lumbar disc decompression with nucleoplasty was performed. The literature was evaluated according to Cochrane review criteria for randomized controlled trials (RCTs), and Agency for Healthcare Research and Quality (AHRQ) criteria was utilized for observational studies. The level of evidence was classified as Level I, II, or III with 3 subcategories in Level II based on the quality of evidence developed by the United States Preventive Services Task Force (USPSTF). A literature search was conducted using only English language literature through PubMed, EMBASE, the Cochrane library, systematic reviews, and cross-references from reviews and systematic reviews.

OUTCOME MEASURES: Pain relief was the primary outcome measure. Other outcome measures were functional improvement, improvement of psychological status, opioid intake, and return to work. Short-term effectiveness was defined as one year or less, whereas, long-term effectiveness was defined as greater than one year.

RESULTS: Based on USPSTF criteria the level of evidence for nucleoplasty is Level II-3 in managing predominantly lower extremity pain due to contained disc herniation.

LIMITATIONS: Paucity of literature, both observational and randomized.

CONCLUSION: This systematic review illustrates Level II-3 evidence for mechanical lumbar percutaneous disc decompression with nucleoplasty in treatment of leg pain. However, there is no evidence available in managing axial low back pain.

Epter RS, Helm S 2nd, Hayek SM, Benyamin RM, Smith HS, Abdi S.

Augusta Pain Center, Augusta, GA 30917-1839, USA. paindoc727@aol.com

Abstract

BACKGROUND: Post lumbar surgery syndrome or failed back surgery syndrome with persistent pain continues to increase over the years. The speculated causes of post lumbar laminectomy syndrome include acquired stenosis, epidural fibrosis, arachnoiditis, radiculopathy, and recurrent disc herniation. Epidural fibrosis may account for as much as 20% to 36% of all cases of failed back surgery syndrome. Percutaneous epidural adhesiolysis has been employed in interventional pain management in the treatment of chronic, refractory low back and lower extremity pain after back surgery.

STUDY DESIGN: A systematic review of randomized trials and observational studies.

OBJECTIVE: To evaluate the effectiveness of percutaneous adhesiolysis in managing chronic low back and lower extremity pain due to post lumbar surgery syndrome.

 

METHODS: A comprehensive literature search was conducted utilizing electronic databases, as well as systematic reviews and cross references from 1966 through December 2008. The quality of individual articles used in this analysis was assessed by modified Cochrane review criteria for randomized trials and the Agency for Healthcare Research and Quality (AHRQ) criteria for assessment of observational studies. Clinical relevance was evaluated using 5 questions according to the criteria recommended by the Cochrane Review Back Group. Analysis was conducted using 5 levels of evidence, ranging from Level I to III, with 3 subcategories in Level II. OUTCOME PARAMETERS: The primary outcome measure was pain relief (short-term relief of at least 6 months and long-term relief of more than 6 months). Secondary outcome measures were improvement in functional status, psychological status, return to work, and change in opioid intake.

RESULTS: Of the 13 studies considered for inclusion, 3 randomized trials and 4 observational studies met the inclusion criteria for methodologic quality assessment and evidence synthesis based on methodologic quality scores of 50 or more. Evidence of percutaneous adhesiolysis in the management of chronic low back pain in post-lumbar surgery syndrome is Level I to Level II-1, with evidence derived from 3 randomized trials.

LIMITATIONS: There is a paucity of efficacy and pragmatic trials. No trials have been published after 2006.

CONCLUSION: The indicated level of evidence for percutaneous adhesiolysis is Level I or II-1 based on the US Preventative Services Task Force (USPSTF) criteria.

Pain ManagementCenter of Paducah, Paducah, KY, USA. drlm@thepainmd.com

Abstract

BACKGROUND: Available evidence documents a wide degree of variance in the definition and practice of interventional pain management.

OBJECTIVE: To provide evidence-based clinical practice guidelines for interventional techniques in the treatment of chronic spinal pain.

DESIGN: Best evidence synthesis.

METHODS: Strength of evidence was assessed by the U.S. Preventive Services Task Force (USPSTF) criteria utilizing 5 levels of evidence ranging from Level I to III with 3 subcategories in Level II.

OUTCOMES: Short-term pain relief was defined as relief lasting 6 months or less and long-term relief as longer than 6 months, except < or = one year and > one year for intradiscal therapies, mechanical disc decompression, spinal cord stimulation, and intrathecal infusion systems.

RESULTS: The indicated evidence for therapeutic interventions is Level I for caudal epidural steroid injections in managing disc herniation or radiculitis, and discogenic pain without disc herniation or radiculitis. The evidence is Level I to II-1 for percutaneous adhesiolysis in management of pain secondary to post-lumbar surgery syndrome. The evidence is Level II-1 or II-2 for therapeutic cervical, thoracic, and lumbar facet joint nerve blocks; for caudal epidural injections in managing pain of post-lumbar surgery syndrome, and lumbar spinal stenosis, for cervical interlaminar epidural injections in managing cervical pain (Level II-1); for lumbar transforaminal epidural injections; and spinal cord stimulation for post-lumbar surgery syndrome.

LIMITATIONS: The limitations of this guideline preparation included a paucity of literature, lack of updates, and lack of conflicts in preparation of systematic reviews and guidelines by various organizations.

CONCLUSION: The indicated evidence for therapeutic interventions is variable from Level I to III. This comprehensive review includes the evaluation of evidence for therapeutic procedures in managing chronic spinal pain and recommendations. However, this review and recommendations do not constitute inflexible treatment recommendations or “standard of care.”

Abstract

PURPOSE OF THE STUDY: The short- and mid-term symptom-relief of surgical treatment for lumbar stenosis is generally acknowledged, but the probability of a long-term reoperation remains to be studied. The purpose of this work was to determine the long-term risk of reoperation after surgical treatment of degenerative lumbar stenosis and to search for factors influencing this probability.

MATERIAL AND METHODS: All patients who underwent from 1989 to 1992 surgical treatment for degenerative lumbar spine stenosis were included in this work. At last follow-up, we noted functional outcome using a specific self-administered questionnaire, patient satisfaction, lumbalgia and radiculalgia using a visual analog scale, SF36 quality-of-life, reoperation or not with time since first operation if performed and the reasons and modalities of the reoperation. The probability of reoperation was determined with the acturarial method. A Cox model was used to search for factors linked with the probability of reoperation; variables studied were: age, comorbid factors, extent of the release, posterolateral arthrodesis or not, extent of the potential fusion, use or not of instrumentation for arthrodesis.

RESULTS AND DISCUSSION: The study included 262 patients. At last follow-up, 61 patients had died a mean 3.7+/-3 years after the operation; only one of these patients had a second operation 22 months after the first. Forty-four patients were lost to follow-up at mean 6.6+/-3 years. Among these 44 patients, four had a second operation during their initial follow-up at mean 47 months. One hundred fifty-seven patients were retained for this analysis at mean 15+/-1 years follow-up. Among these 157 patients, 29 had a second operation a mean 75 months after the first. There were four reasons for reoperating: insufficient release, destabilization within or above the zone of release, development or renewed zone of stenosis, development or renewed discal herniation. The risk of a second operation was 7.4% [95% CI 4.8-11.6], 15.4% [95% CI 10.7-21.1] and 16.5% [95% CI 11.7-219] at five, 10 and 15 years respectively after the first operation. Among the risk factors studied, only one had a significant impact on reoperation: extent of the zone of release (p=0.003). Compared with a release limited to one level, the risk of reoperation after release of three levels or more was five times greater [95% CI 1.8-12.7].

Back Pain

Summary: A number of treatments may be effective for low back pain with apparent disagreement between studies due to grouping all lower back pain into the same category. Degenerative disc pain should be separated from sciatica and chronic muscle spasm in future studies. Individualized treatment plans beginning with less intrusive mobilization before manipulation would greatly increase chiropractic outcomes. Long term studies incorporating patient self-treatment with passive (neutral pelvis) as well as active (hydrotherapy, lifestyle) interventions are still lacking.

Low back pain: what is the long-term course? A review of studies of general patient populations.

Hestbaek L, Leboeuf-Yde C, Manniche C.

The Backcenter, Ringe Hospital, Odense University Hospital, 5950 Ringe, Denmark, hestbaek@vip.cybercity.dk

It is often claimed that up to 90% of low back pain (LBP) episodes resolve spontaneously within 1 month. However, the literature in this area is confusing due to considerable variations regarding the exact definitions of LBP as well as recovery. Therefore, the claim – attractive as it might be to some – may not reflect reality. In order to investigate the long-term course of incident and prevalent cases of LBP, a systematic and critical literature review was undertaken. A comprehensive search of the topic was carried out utilizing both Medline and EMBASE databases. The Cochrane Library and the Danish Article Base were also screened. Journal articles following the course of LBP without any known intervention were included, regardless of study type. However, the population had to be representative of the general patient population and a follow-up of at least 12 months was a requirement. Data were extracted independently by two reviewers using a standard check list. The included articles were also independently assessed for quality by the same two reviewers before they were studied in relation to the course of LBP using various definitions of recovery. Thirty-six articles were included. The results of the review showed that the reported proportion of patients who still experienced pain after 12 months was 62% on average (range 42-75%), the percentage of patients sick-listed 6 months after inclusion into the study was 16% (range 3-40%), the percentage who experienced relapses of pain was 60% (range 44-78%), and the percentage who had relapses of work absence was 33% (range 26-37%). The mean reported prevalence of LBP in cases with previous episodes was 56% (range 14-93%), which compared with 22% (range 7-39%) for those without a prior history of LBP. The risk of LBP was consistently about twice as high for those with a history of LBP. The results of the review show that, despite the methodological variations and the lack of comparable definitions, the overall picture is that LBP does not resolve itself when ignored. Future research should include subgroup analyses and strive for a consensus regarding the precise definitions of LBP.

Massage for low-back pain: a systematic review within the framework of the Cochrane Collaboration Back Review Group.

Furlan AD, Brosseau L, Imamura M, Irvin E.

Institute for Work & Health, Toronto, Canada. afurlan@iwh.on.ca

BACKGROUND: Low back pain (LBP) is one of the most common and costly musculoskeletal problems in modern society. Proponents of massage therapy claim it can minimize pain and disability and speed return-to-normal function. OBJECTIVES: To assess the effects of massage therapy for nonspecific LBP. SEARCH STRATEGY: We searched MEDLINE, Embase, Cochrane Controlled Trials Register, HealthSTAR, CINAHL, and dissertation abstracts through May 2001 with no language restrictions. References in the included studies and in reviews of the literature were screened. Contact with content experts and massage associations was also made. SELECTION CRITERIA: The studies had to be randomized or quasirandomized trials investigating the use of any type of massage (using the hands or a mechanical device) as a treatment for nonspecific LBP. DATA COLLECTION AND ANALYSIS: Two reviewers blinded to authors, journals, and institutions selected the studies, assessed the methodologic quality using the criteria recommended by the Cochrane Collaboration Back Review Group, and extracted the data using standardized forms. The studies were analyzed in a qualitative way because of heterogeneity of population, massage technique, comparison groups, timing, and type of outcome measured. RESULTS: Nine publications reporting on eight randomized trials were included. Three had low and five had high methodologic quality scores. One study was published in German, and the rest, in English. Massage was compared with an inert treatment (sham laser) in one study that showed that massage was superior, especially if given in combination with exercises and education. In the other seven studies, massage was compared with different active treatments. They showed that massage was inferior to manipulation and transcutaneous electrical nerve stimulation; massage was equal to corsets and exercises; and massage was superior to relaxation therapy, acupuncture, and self-care education. The beneficial effects of massage in patients with chronic LBP lasted at least 1 year after the end of the treatment. One study comparing two different techniques of massage concluded in favor of acupuncture massage over classic (Swedish) massage. CONCLUSIONS: Massage might be beneficial for patients with subacute and chronic nonspecific LBP, especially when combined with exercises and education. The evidence suggests that acupuncture massage is more effective than classic massage, but this needs confirmation. More studies are needed to confirm these conclusions, to assess the effect of massage on return-to-work, and to measure longer term effects to determine cost-effectiveness of massage as an intervention for LBP.

Department of Epidemiology, University of California-Los Angeles School of Public Health, Los Angeles, California 90095-1772, USA. ehurwitz@ucla.edu

STUDY DESIGN: A randomized clinical trial. OBJECTIVES: To compare the effectiveness of medical and chiropractic care for low back pain patients in managed care; to assess the effectiveness of physical therapy among medical patients; and to assess the effectiveness of physical modalities among chiropractic patients. SUMMARY OF BACKGROUND DATA: Despite the burden that low back pain places on patients, providers, and society, the relative effectiveness of common treatment strategies offered in managed care is unknown. METHODS: Low back pain patients presenting to a large managed care facility from October 30, 1995, through November 9, 1998, were randomly assigned in a balanced design to medical care with and without physical therapy and to chiropractic care with and without physical modalities. The primary outcome variables are average and most severe low back pain intensity in the past week, assessed with 0 to 10 numerical rating scales, and low back-related disability, assessed with the 24-item Roland-Morris Disability Questionnaire. RESULTS: Of 1,469 eligible patients, 681 were enrolled; 95.7% were followed through 6 months. The mean changes in low back pain intensity and disability of participants in the medical and chiropractic care-only groups were similar at each follow-up assessment (adjusted mean differences at 6 months for most severe pain, 0.27, 95% confidence interval, -0.32-0.86; average pain, 0.22, -0.25-0.69; and disability, 0.75, -0.29-1.79). Physical therapy yielded somewhat better 6-month disability outcomes than did medical care alone (1.26, 0.20-2.32). CONCLUSIONS: After 6 months of follow-up, chiropractic care and medical care for low back pain were comparable in their effectiveness. Physical therapy may be marginally more effective than medical care alone for reducing disability in some patients, but the possible benefit is small.

BACKGROUND: Although chiropractors often use physical modalities with spinal manipulation, evidence that modalities yield additional benefits over spinal manipulation alone is lacking. OBJECTIVE: The purpose of the study was to estimate the net effect of physical modalities on low back pain (LBP) outcomes among chiropractic patients in a managed-care setting. METHODS: Fifty percent of the 681 patients participating in a clinical trial of LBP treatment strategies were randomized to chiropractic care with physical modalities (n = 172) or without physical modalities (n = 169). Subjects were followed for 6 months with assessments at 2, 4, and 6 weeks and at 6 months. The primary outcome variables were average and most severe LBP intensity in the past week, assessed with numerical rating scales (0-10), and low back-related disability, assessed with the 24-item Roland-Morris Disability Questionnaire. RESULTS: Almost 60% of the subjects had baseline LBP episodes of more than 3 months’ duration. The 6-month follow-up was 96%. The adjusted mean differences between groups in improvements in average and most severe pain and disability were clinically insignificant at all follow-up assessments. Clinically relevant improvements in average pain and disability were more likely in the modalities group at 2 and 6 weeks, but this apparent advantage disappeared at 6 months. Perceived treatment effectiveness was greater in the modalities group. CONCLUSIONS: Physical modalities used by chiropractors in this managed-care organization did not appear to be effective in the treatment of patients with LBP, although a small short-term benefit for some patients cannot be ruled out.

Department of Epidemiology, UCLA School of Public Health, University of California-Los Angeles, Los Angeles, CA, USA. hertzman_miller@post.harvard.edu

OBJECTIVES: This study examined the difference in satisfaction between patients assigned to chiropractic vs medical care for treatment of low back pain in a managed care organization. METHODS: Satisfaction scores (on a 10-50 scale) after 4 weeks of follow-up were compared among 672 patients randomized to receive medical or chiropractic care. RESULTS: The mean satisfaction score for chiropractic patients was greater than the score for medical patients (crude difference = 5.5; 95% confidence interval = 4.5, 6.5). Self-care advice and explanation of treatment predicted satisfaction and reduced the estimated difference between chiropractic and medical patients’ satisfaction. CONCLUSIONS: Communication of advice and information to patients with low back pain increases their satisfaction with providers and accounts for much of the difference between chiropractic and medical patients’ satisfaction.

UCLA Comprehensive Spine Center and Department of Orthopaedic Surgery, UCLA School of Medicine, Los Angeles, California 90404, USA. lkanim@espineinstitute.com

STUDY DESIGN: Patients with low back pain were asked to recall the pain and impaired functioning that they reported 5-10 years previously as part of the National Low Back Pain prospective follow-up study. In 1998, patients completed an additional follow-up. OBJECTIVES: To compare outcomes using patient-recalled data and prospectively collected data from patients with low back pain and to identify simple, symptom-specific questions that yield reliable responses over an extended period of time. SUMMARY OF BACKGROUND DATA: Outcome assessment based on patient recall may be influenced by a patient’s age, gender, reporting tendency, and current health status. The impact of data collected retrospectively on outcome analyses in spinal patients has not been addressed. METHODS: Patients enrolled in the National Low Back Pain study from 1986 to 1991 completed a self-administered questionnaire at their initial visit. A sample was interviewed by telephone in 1996 and asked to recall pain characteristics and impaired functioning reported at initial examination. A 10-year follow-up (1998) on current health status was conducted by mail. The 1998 follow-up response was separately compared with recalled and initial responses, such that two patient outcome status values were calculated for each question. Agreement was evaluated using Cohen’s kappa. RESULTS: The follow-up evaluation was completed by 144 patients, with a mean interval of 9.4 years. The overall simple kappa was 0.37, indicating “fair” agreement between outcomes based on initial and recalled accounts of pain. Questions on location of pain had kappa values of 0.12-0.58, radicular symptoms 0.28-0.48, and severity of pain 0.11-0.30. CONCLUSIONS: “Fair” to “moderate” agreement was found between outcomes determined by recalled versus initial reports. Accuracy was greatest for queries on frequency, location of pain, and activities affecting pain. Discrepancies were noted for queries on severity of pain, with error bias toward less pain when using the recalled data. Careful selection of questions may yield more accurate outcome measures.

Systematic review of conservative interventions for subacute low back pain.

Pengel HM, Maher CG, Refshauge KM.

School of Physiotherapy, University of Sydney, Sydney, NSW, Australia. hpen1533@mail.usyd.edu.au

OBJECTIVE: To evaluate the effect of conservative interventions on clinically relevant outcome measures for patients with subacute low back pain. This is particularly important because effective treatment for subacute low back pain will prevent the transition to chronic low back pain, a condition that is largely responsible for the high health care costs of low back pain. DESIGN: Systematic review of randomized controlled trials. MAIN OUTCOME MEASURES: Methodological quality of each trial was assessed. Effect sizes and 95% confidence intervals were calculated for pain and disability and risk ratios for return to work. RESULTS: Thirteen trials were located, evaluating the following interventions: manipulation, back school, exercise, advice, transcutaneous electrical nerve stimulation (TENS), hydrotherapy, massage, corset, cognitive behavioural treatment and co-ordination of primary health care. Most studies were of low quality and did not show a statistically significant effect of intervention. For the strict duration of low back pain (six weeks to three months), no evidence of high internal validity was found but when other methodological criteria were considered, evidence was found for the efficacy of advice. Furthermore, there is evidence that when a broader view is taken of the duration of subacute low back pain (seven days to six months), other treatments (e.g. manipulation, exercise, TENS) may be effective. CONCLUSIONS: Our review identified a major gap in the evidence for interventions that are currently recommended in clinical practice guidelines for the treatment of subacute low back pain. Lack of a uniform definition of subacute low back pain further limited current evidence.

[The Efficacy of homeopathy in the treatment of chronic low back pain compared to standardized physiotherapy]

[Article in German]

Gmunder R, Kissling R.

Abteilung fur Physikalische Medizin und Rheumatologie, Orthopadische Universitatsklinik Balgrist, Zurich, Switzerland.

AIM: The aim of this pilot project was to evaluate the efficacy of treatment of chronic low back pain during two months either by homeopathy or by standardised physiotherapy. METHOD: 43 patients suffering from chronic low back pain were included in this controlled, randomised prospective study. They were divided in two treatment groups: homeopathy and standardised physiotherapy. Based on the initial and final clinical investigations, the Oswestry questionnaire and the visual analogue scale, that were assessed at the beginning, at the end and 18.5 months after therapy, the results were statistically evaluated. A further questionnaire documented the acceptance of treatment. RESULTS: A comparison of the groups from the beginning to the end of treatment reveals a significant decrease of the Oswestry score in patients treated by homeopathy. This tendency could not be confirmed 18.5 months later.Homeopathy was well accepted by most of the patients. CONCLUSIONS: Based on these results, nothing can be said against attempting treatment of chronic low back pain by means of homeopathy. Further research is recommended to confirm the results of our investigation, using a larger number of patients, a third treatment group, homeopathy double blinded.

Measles In the 21st Century: Is It Vaccine Refusal That Causes Outbreaks?

Whenever there are cases of measles, or any childhood illness that has a vaccine, the immediate blame falls on parents who refuse to vaccinate their children.  (Pittsburgh editorial)

In the U.S. the rate of refusal of vaccines by parents is less than 2%. (CDC 2010) Given that outbreaks often include both vaccinated and unvaccinated individuals, it is clear that the transmission of measles can take place between vaccinated individuals.

While it is enticing to simply blame outbreaks of measles on unvaccinated individuals, the reality is that the vaccine itself is not fool proof, and may provide varying immunity based even on the timing of the vaccination. “Vaccine efficacy rose from 85% in children vaccinated at 12 months of age to > or = 94% in those vaccinated at 15 months and older.” (study here)

Rather than focusing on the tiny percentage of parents refusing vaccination, public health dollars and attention should be focused on the evolving threat of measles in a vaccinated world. Studies from France found that health care workers who had been vaccinated still contracted measles, and likely passed on the virus to their charges (below). Even after mandatory universal vaccination, Singapore still sees a few cases of measles.  They also see a large number of false positive diagnoses, where the majority of cases diagnosed as measles are not that virus at all.

Measles represents the most highly effective vaccine within its MMR combination.  The mumps component has at best 88% efficacy (below), making the primary problem with its transmission the strength of the vaccine rather than the resistance of parents.

“Since early 2008, France has been experiencing a measles outbreak with almost 5,000 notified cases as of 30 June 2010, including three measles-related deaths. The proportion of cases 20 years or older reached 38% during the first half of 2010. This situation is the consequence of insufficient vaccine coverage (90% at age 24 months in 2007) that led to the accumulation of susceptibles over the last years.”

Abstract

 “Low vaccine coverage can lead to the persistence of preventable diseases and, in some cases, to a dangerous shift in the age of pathogen encounter towards adulthood. This is the case of measles in Europe, where some countries, including France, have not reached the effective vaccine coverage rate of 95%.”

“Vaccine effectiveness of one dose of the MMR vaccine ranged from 49.2% to 81.6%, whereas vaccine effectiveness of two doses ranged from 66.3% to 88.0%. If we assume vaccine effectiveness of 85% for two doses of the vaccine, vaccine coverage of 88.2% and 98.0% would be needed to interrupt community transmission of mumps”

Maine State Law Regarding Naturopathic Doctors

As a licensed Naturopathic doctor, I have public health obligations and continuing education obligations.  I carry malpractice insurance, and I am authorized to order and interpret laboratory tests as well as prescribe pharmaceutical medications.

Under Maine State Law, a Naturopathic Doctor’s scope of practice is:

“A naturopathic doctor may use and order for preventative and therapeutic purposes the following natural medicines and therapies: food, food extracts, vitamins, minerals, enzymes, digestive aids, whole gland thyroid and other natural hormones, plant substances, all homeopathic preparations, immunizations, counseling, hypnotherapy, biofeedback, dietary therapy, naturopathic manipulative therapy, naturopathic physical medicine, therapeutic devices, barrier devices for contraception and office procedures. Naturopathic doctors may also prescribe medications, including natural antibiotics and topical medicines, within the limitations set forth in subsection 4.”

The Complete Course Schedule Of A Naturopathic Doctor

While it is less relevant now that I’ve been out of school for twelve years, I think letting patients know about my course schedule gives them a sense of the way I was trained.

For those of you who want to know exactly what I’ve been trained in, I am including my class schedules for four years.  Ask all your doctors for their course schedules.  Many of them have all their education stuffed into one or two years. Look particularly for classes in nutrition, as most of us trust them to know about what we should eat, and many of them have had no training. Comparisons in class time actually show I took more class hours than MDs at John Hopkins or Harvard. The difference is that the MD medical students are working 120 hour weeks in the hospitals. They learn a great deal about acute hospital care. I do not work in a hospital setting, and all my clinical training is in an outpatient setting. Since most MD students complete primarily hospital training, our outpatient training is comparable.

What Is A Naturopath?

How do I define a Naturopath? (Go to my youtube video where I discuss my personal definition of what I do).

Short answer according to an online dictionary:

na•tur•op•a•thy   /ˌneɪtʃəˈrɒpəθi, ˌnætʃə-/ Show Spelled

[ney-chuh-rop-uh-thee, nach-uh-] –noun

a system or method of treating disease that employs no surgery or synthetic drugs but uses special diets, herbs, vitamins, massage, etc., to assist the natural healing processes.

A Naturopath treats disease differently from an Osteopath or an Allopath.

So what are those?

An Osteopath is someone who practices primary care and who was trained in osteopathic manipulation. At this point, many never use their manipulation training but they maintain a separate identity from the Allopaths. Most Osteopaths consider primary care to be very important. Beyond that, Osteopathy has been absorbed into Allopathy. Less than a third of Osteopaths could give an example of any philosophical or physical difference in their practices from their Allopathic colleagues. (http://en.wikipedia.org/wiki/Comparison_of_MD_and_DO_in_the_United_States)

An Allopath is a conventional M.D. who treats using primarily drugs and surgery. A number of sites claim that this is a derogatory term, but it is used both by the Association of American Medical Colleges and the national student association to differentiate M.D.s from others. Allopaths do not share a common philosophy, and, despite the common myth, do not all even take the same Hippocratic Oath. There is a call for M.D.s to generate a common Hippocratic Oath, but it is unlikely to take hold.

Naturopathy is fortunate in that its practitioners agree on a philosophy of treatment. While Naturopathic treatment is extremely diverse, all Naturopaths should adhere to the following philosophy of treatment.

From The Southwest Naturopathic School:

The six principles that guide the therapeutic methods and modalities of Naturopathic medicine include:

First Do No Harm – primum non nocere
Naturopathic medicine uses therapies that are safe and effective.

The Healing Power of Nature – vis medicatrix naturae
The human body possesses the inherent ability to restore health. The physician’s role is to facilitate this process with the aid of natural, nontoxic therapies.

Discover and Treat the Cause, Not Just the Effect – tolle causam
Physicians seek and treat the underlying cause of a disease. Symptoms are viewed as expressions of the body’s natural attempt to heal. The origin of disease is removed or treated so the patient can recover.

Treat the Whole Person – tolle totum
The multiple factors in health and disease are considered while treating the whole person. Physicians provide flexible treatment programs to meet individual health care needs.

The Physician is a Teacher – docere
The physician’s major role is to educate, empower, and motivate patients to take responsibility for their own health. Creating a healthy, cooperative relationship with the patient has a strong therapeutic value.

Prevention is the best “cure” – praevenire
Naturopathic physicians are preventive medicine specialists. Physicians assess patient risk factors and heredity susceptibility and intervene appropriately to reduce risk and prevent illness. Prevention of disease is best accomplished through education and a lifestyle that supports health.

Allopathy: The system of medical practice which treats disease by the use of remedies which produce effects different from those produced by the disease under treatment. MDs practice allopathic medicine.

The term “allopathy” was coined in 1842 by C.F.S. Hahnemann to designate the usual practice of medicine (allopathy) as opposed to homeopathy, the system of therapy that he founded based on the concept that disease can be treated with drugs (in minute doses) thought capable of producing the same symptoms in healthy people as the disease itself.

In 2005, Jordan Cohen, the president of the Association of American Medical Colleges wrote,

“after more than a century of often bitterly contentious relationships between the osteopathic and allopathic medical professions, we now find ourselves living at a time when osteopathic and allopathic graduates are both sought after by many of the same residency programs; are in most instances both licensed by the same licensing boards; are both privileged by many of the same hospitals; and are found in appreciable numbers on the faculties of each other’s medical schools.[5]

U.S. News surveyed the 126 allopathic medical schools accredited by the Liaison Committee on Medical Education (LCME) in 2008, plus the 20 osteopathic medical schools accredited by the American Osteopathic Association the same year. In total, 122 schools provided the data necessary to rank the quality of their research and primary care components.
