Is acupuncture in addition to conventional medicine effective as pain treatment for endometriosis? A randomised controlled cross-over trial.

OBJECTIVE: The aim of the study was to examine whether acupuncture is an effective additional pain treatment for endometriosis. STUDY DESIGN: One hundred and one women aged 20-40 years participated and were randomised into two groups, each receiving two units of 10 acupuncture treatments, twice a week over a period of five weeks. Group 1 (n = 47) received verum-acupuncture during the first series, and group 2 (n = 54) received non-specific acupuncture. After the first unit of 10 treatments, an observation period of at least two menstruation cycles was set, followed by a second unit, according to a cross-over design. Prior to the study (during a two-week run-in period) the patients' actual pain intensity was surveyed. Throughout the study period, participants were asked to keep a 'pain protocol', in which they defined and recorded their pain according to the 10-point visual analogue scale (VAS). RESULTS: Eighty-three out of a total of 101 patients finished the study. Group 1 showed a significant reduction of pain intensity after the first 10 treatments. In comparison, group 2 showed significant pain relief only after the cross-over. CONCLUSION: Acupuncture treatment on specific acupuncture points appears to be an effective pain treatment for endometriosis, but this has to be confirmed in further study.

Needle acupuncture in chronic poststroke leg spasticity.

OBJECTIVE: To determine whether needle acupuncture may be useful in the reduction of leg spasticity in a chronic state. DESIGN: Single-blind, randomized, placebo-controlled trial. SETTING: Neurologic outpatient department of a medical school in Germany. PARTICIPANTS: Twenty-five patients (14 women) suffering from chronic poststroke leg spasticity with pes equinovarus deformity (Modified Ashworth Scale [MAS] score, >/=1), aged 38 to 77 years (mean +/- standard deviation, 58.5+/-10.4 y), were enrolled in the study. The mean time from stroke to inclusion in the study was approximately 5 years (mean, 65.4+/-48.3 mo; range, 7-180 mo). INTERVENTIONS: Participants were randomly assigned to placebo treatment (n=12) by using a specially designed placebo needling procedure, or verum treatment (n=13). MAIN OUTCOME MEASURES: MAS score of the affected ankle, pain (visual analog scale), and walking speed. RESULTS: There was no demonstrated beneficial clinical effects from verum acupuncture. After 4 weeks of treatment, mean MAS score was 3.3+/-0.9 in the placebo group versus 3.3+/-1.1 in the verum group. The neurophysiologic measure of H-reflex indicated a significant increase of spinal motoneuron excitability after verum acupuncture (H-response/M-response ratio: placebo,.39+/-.19; verum,.68+/-.41; P<.05). CONCLUSIONS: This effect might be explained by afferent input of A delta and C fibers to the spinal motoneuron. The results from our study indicate that needle acupuncture may not be helpful to patients with chronic poststroke spasticity. However, there was neurophysiologic evidence for specific acupuncture effects on a spinal (segmental) level involving nociceptive reflex mechanisms.
