According to acupuncture therapy for dystonia patients practised at the Outpatient Clinic, Kansai College of Oriental Medicine, there is a report that remote acupuncture therapy by the meridian concept is effective. It was reported that dystonia is sensory defect rather than dyskinesia, and we report acupuncture therapy of soft stimulus to normalize the upper central nervous system for stimulated sensory nerve. Based on the meridian theory, we investigated the influence of acupuncture stimulus to the sternocleidomastoid muscle (L14) through which the large intestine meridian (L1) passes on the hand, on the central nervous system and muscles by comparison of surface EMGS among 3 groups: no stimulus, 5 min stimulus, 20 min stimulus. After 20 min stimulus, both PMT and MT were significantly shortened compared with before stimulus. However, in the no stimulus and 5 min stimulus groups there were no differences in PMT and MT compared with before stimulus. This suggests that to excite the central nervous system and muscle function via the sternocleidomastoid muscle, 20 min acupucture is needed.
