Muscle activities and three dimentional photographic pictures at the same time.Each values are converted to digital values through adequate digitazing tools. By measuring photographic pictures, positions and velocities of hand movement are obtained. Electromyographic wave are put into computer through A/D convertor, processed by the method of ordinary digital processing of signals, give the necessary information of muscle activites.The relation between the joint position and role and activities of muscles in each stages of hand movement were made clear by spontaneous recording of electromyography and pictures.
