ABSTRACT
Objective To sift and optimize pulse width for electroacupuncture prevention and treatment of muscular atrophy. Method A model of lower limb muscle atrophy was made in 40 rats. They were randomized into groupsⅠ (no electroacupuncture),Ⅱ (a pulse width of 0.5 ms and a frequency of 2 Hz), Ⅲ (a pulse width of 100 ms and a frequency of 2 Hz) and Ⅳ (a pulse width of 200 ms and a frequency of 2 Hz). Points Zusanli (ST36) and Chengshan(BL57) were given electroacupuncture. Sciatic function index (SFI), gastrocnemius muscle wet weight ratio (GW), the cross-sectional area of gastrocnemius muscle fibers (GC), gastrocnemius muscle cell diameter (GD) and gastrocnemius muscle cell apoptosis index (AI) were used as indicators of therapeutic effect. Result Compared with group Ⅰ, SFI and GW increased significantly in groups Ⅲ and Ⅳ (P<0.05). Compared with groupsⅠ and Ⅱ, AI on the affected side decreased significantly in groups Ⅲ and Ⅳ (P<0.05). Conclusion The therapeutic effect of electroacupuncture is related to its pulse width. The pulse widths of 100 ms and 200 ms are significantly more effective than a pulse width of 0.5 ms from a conventional electroacupuncture device in preventing and treating muscular atrophy.
