The effectiveness of acupuncture for depression – a systematic review of randomised controlled trials

Objective To summarise the existing evidence on acupuncture as a therapy for depression. Methods RCTs were included, in which either manual acupuncture or electroacupuncture was compared with any control procedure in subjects with depression. Data were extracted independently by two authors. The methodological quality was assessed. Pre and post means and SDs for depression specific measures were extracted, when available, for meta-analysis. Results Seven randomised comparative trials involving 509 patients were included. The evidence is inconsistent on whether manual acupuncture is superior to sham, and suggests that acupuncture was not superior to waiting list. Evidence suggests that the effect of electroacupuncture may not be significantly different from antidepressant medication, weighted mean difference −0.43(95% CI −5.61 to 4.76). There is inconclusive evidence on whether acupuncture has an additive effect when given as an adjunct to antidepressant drugs. Conclusion The evidence from controlled trials is insufficient to conclude whether acupuncture is an effective treatment for depression, but justifies further trials of electroacupuncture.

Applicability of press needles to a double-blind trial: a randomized, double-blind, placebo-controlled trial.

ObjectivesOwing to a lack of a suitable needle procedure, it has been impossible to evaluate the efficacy of acupuncture in clinical studies using double-blind testing. We evaluated the applicability of a new kind of press needle (Pyonex) to a double-blind trial by comparing the press needle with a placebo (lacking the needle element). MethodsThe purpose of the study consisted of 2 phases. In the phase 1, to evaluate the applicability and efficacy of the press needles, 90 participants who had never been treated using acupuncture were randomly assigned to receive either the press needle (n=45) or a placebo (n=45). The applicability was measured using a questionnaire regarding the perception of penetration, and efficacy was measured using a visual analog scale of low back pain (LBP). When the applicability and efficacy of the press needles were confirmed in phase 1, the mechanism of LBP relief by the press needles was examined in phase 2. ResultsIn phase 1, intergroup comparisons showed no significant differences concerning the perception of penetration. In addition, for patients with LBP, the press needles reduced the subjective evaluation of LBP compared with the placebo (P<0.05). In phase 2, visual analog scale results indicated that LBP was reduced significantly more in the press needle group than in the local anesthesia group (P<0.05). DiscussionThe participants could not distinguish between the press needle and a placebo, and the data from the press needle group suggested a specific influence on patients with LBP. These findings imply that the press needle and a placebo provide an effective means of realizing a double-blind setting for clinical studies of acupuncture.

Effects of active individual muscle stretching on muscle function.

[Purpose] We investigated the effect of active individual muscle stretching (AID) on muscle function. [Subjects] We used the right legs of 40 healthy male students. [Methods] Subjects were divided into an AID group, which performed stretching, and a control group, which did not. We examined and compared muscle function before and after stretching in the AID and control groups using a goniometer and Cybex equipment. [Results] A significant increase in flexibility and a significant decrease in muscle strength output were observed in the AID group after the intervention. [Conclusion] These results suggest that AID induces an increase in flexibility and a temporary decrease in muscle output strength.

Graded meridian test program to prevent bullying: Preliminary study

We conducted a study on the effects of a graded meridian test (M‐Test) program on bullying and stress emotions in an elementary school.

Relaxing effect of lower leg acupuncture in sedentary university students with regard to physical movement and autonomic nerve activity: Randomized controlled trial

To demonstrate the utility of press needles on the lower limbs in improving response to straight leg raise (SLR) test and cervical movement.

Acupuncture practitioner-patient communication in Japan.

We evaluated acupuncture practitioner–patient communication using pairs of practitioners and patients. Our primary objective was to evaluate the concordance of practitioner and patient perceptions in terms of explanations regarding consultation, therapy, and patient satisfaction. The subjects were 250 practitioners and their 1250 patients in Fukuoka, Japan. Answers were obtained from 91 acupuncture practitioners (36.40%) and 407 patients (32.56%). Of these, responses from 125 pairs without missing values were used for the analysis. When practitioner–patient communication, as evaluated by the difference between the patients’ and the practitioners’ perceptions with respect to the level of practitioner explanation, was good, patient outcome (ie, satisfaction with therapy, improvement in health) was also good. Factors related to poor practitioner–patient communication included age of the practitioner, the number of practitioners at a clinic, the experience of the practitioner, and the age of the patient. These findings may be useful in improving practitioner–patient communication.
