PainSci summary of Green 2005?This page is one of thousands in the PainScience.com bibliography. It is not a general article: it is focussed on a single scientific paper, and it may provide only just enough context for the summary to make sense. Links to other papers and more general information are provided at the bottom of the page, as often as possible. ★★★☆☆?3-star ratings are for typical studies with no more (or less) than the usual common problems. Ratings are a highly subjective opinion, and subject to revision at any time. If you think this paper has been incorrectly rated, please let me know.

Acupuncture is damned with faint praise by the results of this review, as with most other reviews. The authors do bend over backwards to conclude that “there may be short-term benefit with respect to pain and function,” but this token positivity is based on scraps of unimpressive data: “The improvements with acupuncture for pain and function were about the same as the effects of receiving a fake therapy for 2 to 4 weeks.” Emphasis mine.

“There is little evidence to support or refute the use of acupuncture for shoulder pain,” the authors conclude. Little evidence to specifically refute it, perhaps … but plenty of reasons to refute it.

original abstract

BACKGROUND: There are many commonly employed forms of treatment for shoulder disorders. This review of acupuncture is one in a series of reviews of varying interventions for shoulder disorders including adhesive capsulitis (frozen shoulder), rotator cuff disease and osteoarthritis. Acupuncture to treat musculoskeletal pain is being used increasingly to confer an analgesic effect and to date its use in shoulder disorder has not been evaluated in a systematic review.

OBJECTIVES: To determine the efficacy and safety of acupuncture in the treatment of adults with shoulder pain.

SEARCH STRATEGY: The Cochrane Controlled Trials Register, MEDLINE, EMBASE and CINAHL were searched from inception to December 2003, and reference lists from relevant trials were reviewed.

SELECTION CRITERIA: Randomised and quasi-randomised trials, in all languages, of acupuncture compared to placebo or another intervention in adults with shoulder pain. Specific exclusions were duration of shoulder pain less than three weeks, rheumatoid arthritis, polymyalgia rheumatica, cervically referred pain and fracture.

DATA COLLECTION AND ANALYSIS: Two reviewers independently extracted trial and outcome data. For continuous outcome measures where the standard deviations were not reported it was either calculated from the raw data or converted from the standard error of the mean. If neither of these was reported, authors were contacted. Where results were reported as median and range, the trial was not included in the meta-analysis, but presented in Additional Tables. Effect sizes were calculated and combined in a pooled analysis if the study end-points population and intervention were homogenous. Results are presented separately for rotator cuff disease, adhesive capsulitis, full thickness rotator cuff tear and mixed diagnoses, and, where possible, combined in meta-analysis to indicate effect of acupuncture across all shoulder disorders.

MAIN RESULTS: Nine trials of varying methodological quality met the inclusion criteria. For all trials there was poor description of interventions. Varying placebos were used in the different trials. Two trials assessed short-term success (post intervention) of acupuncture for rotator cuff disease and could be combined in meta analysis. There was no significant difference in short-term improvement associated with acupuncture when compared to placebo, but due to small sample sizes this may be explained by Type II error. Acupuncture was of benefit over placebo in improving the Constant Murley Score (a measure of shoulder function) at four weeks (WMD 17.3 (7.79, 26.81)). However, by four months, the difference between the acupuncture and placebo groups, whilst still statistically significant, was no longer likely to be clinically significant (WMD 3.53 (0.74, 6.32)). The Constant Murley Score is graded out of 100, hence a change of 3.53 is unlikely to be of substantial benefit. The results of a small pilot study demonstrated some benefit of both traditional and ear acupuncture plus mobilization over mobilization alone. There was no difference in adverse events related to acupuncture when compared to placebo, however this was assessed by only one trial.

AUTHORS' CONCLUSIONS: Due to a small number of clinical and methodologically diverse trials, little can be concluded from this review. There is little evidence to support or refute the use of acupuncture for shoulder pain although there may be short-term benefit with respect to pain and function. There is a need for further well designed clinical trials.
