[Effect of warm acupuncture stimulation of Waiguan (TE 5) on post-stroke shoulder-hand syndrome].

OBJECTIVE: To evaluate the therapeutic effect of warm acupuncture (moxa-heated acupuncture) needle stimulation of Waiguan (TE 5) acupoint in the treatment of shoulder-hand syndrome (phase I) in patients with stroke. METHODS: Sixty stroke patients with shoulder-hand syndrome (phase I ) were equally randomized into control group and warm acupuncture group. Patients of the warm acupuncture group were treated by warm acupuncture stimulation of the affected TE 5 in combination with routine acupuncture stimulation of Jianyu (LI 15), Jianjing (GB 21), Quchi (LI 11), Wangu (SI 4), Yangchi (TE 4) and Hegu (LI 4), and rehabilitation training (passive and active upper-limb motion exercise for 30 min, once daily), and patients of the control group treated with routine acupuncture stimulation of the same acupoints mentioned above, and rehabilitation training. The treatment was conducted once daily, 5 times per week for two weeks. The patients' clinical conditions were evaluated by using Visual Analogue Scale (VAS, 0-10 points, shoulder pain degree), edema severity score (0 point:normal, 2 points: mild, 4 points: moderate, and 6 points: severe) and simplified Fugl-Meyer motor assessment scale (0, 1 and 2 points, upper-limb motor function) before and after the treatment. RESULTS: After the treatment, the scores of VAS and edema severity of the two groups were significantly decreased in comparison with pre-treatment in the same one group (P < 0.01), and the Fugl-Meyer motor scores were considerably increased (P < 0.01), suggesting an improvement of the shoulder-hand syndrome after two weeks' treatment. Of the two 30 patients in the control group and warm acupuncture group, 0 and 2 (6.7%) were cured, 7 (23.3%) and 25 (83.3%) experienced marked improvement, 17 (56.7%) and 2 (6.7%) were effective, 6 (20. 0%) and 1 (3.3%) invalid, with the effective rates being 80.0% and 96.7%, respectively. The effect of warm acupuncture group was superior to that of the control group (P < 0.05). CONCLUSION: Warm acupuncture combined with routine acupuncture and rehabilitation training is effective in improving shoulder pain, hand edema and limb motor function in stroke patients with shoulder-hand syndrome at phase I.
