[Post-stroke hand spasm treated with penetrating acupuncture combined with kinesiotherapy: a randomized controlled trial].

OBJECTIVE: To compare the differences in the clinical effect on post-stroke hand spasm among the combined treatment of penetrating acupuncture and kinesiotherapy, the simple application of penetrating acupuncture and the simple application of kinesiotherapy. METHODS: A total of 105 patients with post-stroke hand spasm were randomized into a penetrating acupuncture group, a kinesiotherapy group and a combined treatment group, 35 cases in each one, of which, 2 cases were dropped out in either the combined treatment group and the penetrating acupuncture group, and 1 case dropped out in the kinesiotherapy group. The routine rehabilitation training, e.g. occupational therapy and Bobath exercise and medication were adopted in all of the three groups. In the penetrating acupuncture group, the penetrating needling technique was exerted from Hegu (LI 4) to Houxi (SI 3) and from Waiguan (TE 5) to Sidu (TE 9) on the affected side. In the kinesiotherapy group, the persistent movement or passive movement was exerted on the wrist joint, the metacarpophalangeal joints and the interphalangeal joints. In the combined treatment group, the penetrating acupuncture (the same as the penetrating acupuncture group) was exerted combined with kinesiotherapy (the same as the kinesiotherapy group). In each group, the treatment was given once a day, 30 min in each time, 6 treatments a week in total, with the interval of 1 day between the courses. The treatment for 2 weeks was as one course and 2 courses were required totally. Before and after treatment, the scores of hand spasm index, hand-wrist motor function and the activity of daily living (ADL) were compared in each group. RESULTS: After treatment, the scores of hand spasm index were reduced as compared with those before treatment in each group (P<0.05) and the scores of hand-wrist motor function and ADL were increased significantly as compared with those before treatment in each group (P<0.05). After treatment, the reducing degree of the score of hand spasm index in the combined treatment group was greater than the penetrating acupuncture group and the kinesiotherapy group (P<0.01), and the increasing degree of the scores of hand-wrist motor function and ADL were higher than either the penetrating acupuncture group or the kinesiotherapy group (P<0.01). The improvements in each index were not different statistically between the kinesiotherapy group and the penetrating acupuncture group (P>0.05). CONCLUSION: Compared with the simple application of either penetrating acupuncture or kinesiotherapy, the combined treatment of them achieves the significant improvements in hand spasm degree, hand wrist motor function and ADL in patients with stroke.
