Acupuncture for chronic shoulder pain. An experimental study with attention to the role of placebo and hypnotic susceptibility. [A comparison between the pain relief effect of electroacupuncture, regional never block and electroacupuncture plus regional never block in frozen shoulder]. Acupuncture for frozen shoulder. Acupuncture and Trager psychophysical integration in the treatment of wheelchair user's shoulder pain in individuals with spinal cord injury. International research project to devise a protocol to test the effectiveness of acupuncture on painful shoulder. Randomised clinical trial comparing the effects of acupuncture and a newly designed placebo needle in rotator cuff tendinitis.
One half of 42 subjects treated for painful shoulders received classic acupuncture, and one half received a placebo in which the needles did not penetrate the skin. Half of each of these groups was treated in a positive setting to encourage the subject, and half in a negative setting designed to keep encouragement at a minimum. All patients were independently rated for susceptibility to hypnosis. Although range of motion did not improve, the majority of patients reported significant improvement in shoulder discomfort to a blind evaluator after treatment; placebo and acupuncture groups did not differ in this respect, however. The positive and negative settings did not affect treatment outcome. In all groups, those who were not rated as highly susceptible to hypnosis tended to fail to achieve the highest levels of relief, but such differences were not statistically significant. Frozen shoulder is a kind of spontaneous, progressive peri-arthritis over the shoulder joint. The etiology is not yet clear. Traditional treatments for frozen shoulder included conservative medical therapy, physical therapy, nerve block and acupuncture and so on. The purpose of our study is to determine the pain relief effect of electroacupuncture (EAP), regional nerve block (RNB) and the combination of EAP + RNB for frozen shoulder.
                One hundred and fifty patients with fresh frozen shoulder were, randomly divided into 3 groups. Group I patients (n = 50) had RNB with stellate ganglion block and suprascapular nerve block by 1% xylocaine 10 ml. Group II patients (n = 50) had EAP with local acupoint--Chien-Yu, Chien-Ching, Chien-Nei-Ling, Ah-Shih Hsueh treatment and Group III (n = 50) patients had RNB+EAP performed with acupuncture first, then followed by the regional nerve block. Six vectors of movements were checked in all methods. Four graded Bromage score was used for pain assessment, Grade 1 means complete painless; Grade 2 means slight pain (i.e. pain on motion); Grade 3 means moderate pain (i.e. pain on silence); Grade 4 means severe pain (i.e. need analgesics). The range of shoulder joint was also recorded. Patients were requested for second treatment if pain recurred. The onset (time from injection to maximal pain relief), duration (time from injection to grade 3) Bromage score and side effects were recorded.
                The results showed that the combined EAP and RNB method had significant high pain control quality, longer duration, and better range of movement of the shoulder joint than that of EAP or RNB performed alone. This randomised controlled trial was undertaken to evaluate the effectiveness of acupuncture as a treatment for frozen shoulder. Thirty-five patients with a diagnosis of frozen shoulder were randomly allocated to an exercise group or an exercise plus acupuncture group and treated for a period of 6 weeks. Functional mobility, power, and pain were assessed by a blinded assessor using the Constant Shoulder Assessment, at baseline, 6 weeks and 20 weeks. Analysis was based on the intention-to-treat principle. Compared with the exercise group, the exercise plus acupuncture group experienced significantly greater improvement with treatment. Improvements in scores by 39.8% (standard deviation, 27.1) and 76.4% (55.0) were seen for the exercise and the exercise plus acupuncture groups, respectively at 6 weeks (P=0.048), and were sustained at the 20-week re-assessment (40.3% [26.7] and 77.2% [54.0], respectively; P=0.025). We conclude that the combination of acupuncture with shoulder exercise may offer effective treatment for frozen shoulder. To determine the effectiveness of acupuncture and Trager Psychophysical Integration (a form of manual therapy) in decreasing chronic shoulder pain in wheelchair users with spinal cord injury (SCI).
                A prospective clinical trial, with subjects randomized to acupuncture or Trager treatment condition. Subjects served as their own controls by including a 5-week pretreatment baseline period and a 5-week posttreatment follow-up period.
                Rehabilitation hospital research department.
                Eighteen subjects with chronic SCI and chronic shoulder pain who used manual wheelchairs as their primary means of mobility.
                Ten acupuncture or 10 Trager treatments over a 5-week period.
                Changes in performance-corrected Wheelchair User's Shoulder Pain Index (PC-WUSPI) scores during baseline, treatment, and follow-up periods were assessed by using analysis of variance.
                The mean PC-WUSPI score +/- standard deviation of the 18 subjects at entry was 48.9 +/- 24.6 (range, 8.0-94). No significant change in mean PC-WUSPI scores occurred during the pretreatment baseline period. Mean PC-WUSPI scores decreased significantly during the treatment period in both the acupuncture (53.4%; 23.3 points) and Trager (53.8%; 21.7 points) treatment groups. The reduced PC-WUSPI scores were maintained in both groups throughout the 5-week posttreatment follow-up period.
                Acupuncture and Trager are both effective treatments for reducing chronic shoulder pain associated with functional activities in persons with SCI. To describe in detail the questions and deliberations leading to the development of a methodologically rigorous protocol to test the effectiveness of acupuncture on painful shoulder.
                Randomized controlled trial using three groups, including one control group.
                A hospital in the north of Italy treating at least 8-10 painful shoulders a day, with physician/acupuncturists, physiotherapists, and assessors available to participate in the study.
                Sixty patients with monolateral painful shoulder. A list of exclusion criteria is given.
                Acupuncture + mobilization; mobilization alone (control); ear acupuncture + mobilization.
                Severity of pain, scored on a visual analogue scale (VAS) and on the McGill Pain Questionnaire and restriction of range of motion (ROM) of the shoulder joint. Voluntary use of pain medication, Tenoxicam 20 mg, was added to the protocol.
                The research team developed a protocol and methodology that avoids the common flaws and difficulties of previous clinical trials on acupuncture.
                Physicians and acupuncture specialists will benefit from the advice and support of a project group consisting of experienced clinicians, researchers, and statisticians when designing and preparing clinical trials on acupuncture and other complementary and alternative therapies. Acupuncture has gained increasing attention in the treatment of chronic pain. The lack of a satisfying placebo method has made it impossible to show whether needling is an important part of the method or whether the improvement felt by the patient is due to the therapeutic setting and psychological phenomena. Also, the effectiveness of acupuncture has not been demonstrated sufficiently. We treated 52 sportsmen with rotator cuff tendinitis in a randomised single-blind clinical trial using a new placebo-needle as control. Patients were treated for 4 weeks. The primary endpoint of the trial was the change in the modified Constant-Murley-score from the baseline. Assessment of the treatment outcome was made by experienced orthopaedists not informed of the treatment allocation. Acupuncture with penetration of the skin was shown to be more effective than a similar therapeutic setting with placebo needling in the treatment of pain. The acupuncture-group improved 19.2 Constant-Murley-score points (SD 16.1, range from -13 to 50), the control-group improved 8.37 points (SD 14.56, range from -20 to 41), (P=0.014; C.I. 2.3;19.4). This study showed that needling is an important part of the acupuncture effect in the treatment of chronic shoulder pain in athletes. No conclusions can be derived from this study concerning the importance of choosing points and the rules of Traditional Chinese Medicine. Using the new placebo method as control for other ailments could improve the evidence of specific acupuncture effects beyond pain treatment.
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.
