Abstract

The purpode of this study was to determine the EMG characteristies of 7 subjects with hemiplegic gait receiving therapeautic exercise after stroke. The akin electrode and gait analysis system were used. The normal gait of 6 health volunteers was analysised. The results were following. 1. Gluteus maximus, the extensor of hip joint had high level of activity compared to normal, and had two peak in late stance phase and early Swing phase. 2. Medial hamstring, the flexor of knee joint had low level of activity compared to normal, and had continuous low amplitude pattern. 3. Vastus lateralis, the extensor of knee joint had high level of activity compared to normal, and had not continuous high amplitude. From early stance phase and mid stance phase, activity had high level but after swing phase. similar to normal. 4. Gastrocnemius, plantar flexor of ankle joint had low level of activity compared to normal and had continuous low amplitude. 5. Tibialis anterior, dorsiflexor of ankle joint had similar muscle activity to normal and had continuous low amplitude.
