摘要

The purposes of this study are 1. To monitor the improvement of muscle performance following Russian stimulation training by muscle strength test and compound muscle action potential (CMAP) recording. 2. To investigate the place of quantitative CMAP recording technique in evaluation of muscle power. the APB and ADQ muscles from 20 healthy volunteer were included. Muscle strength was recorded by strain gauge, and CMAP of both muscles were recorded by Viking EMG following supramaximal electrical stimulation at wrist. Two evaluation sequences were done before and after Russian stimulation training of APB and ADQ muscles for 1 month. Results disclosed that, although muscle strength increased significantly after training (p＜0.001), the latency, amplitude, duration and surface area of the CMAP failed to show statistical differences before and after training. We conclude that Russian stimulation training may improve the muscle strength, but this improvement can not be monitored by just recording the CMAP. Further advanced techniques such as integrated EMG and power spectrum analysis will be considered as our future investigation tools.
