New Neuromuscular Training for Peripheral Nerve Disorders Using an Ankle Joint Hybrid Assistive Limb: A Case Series

Peripheral nerve disorder of the lower extremities causes drop foot and disturbs daily living activities patients. The ankle joint hybrid assistive limb (HAL) provides voluntary training using surface bioelectrical signals from muscles extremities. We investigated neurological effects HAL in three Sensory action potentials (SNAPs) compound muscle (CMAPs) were analyzed for peroneal tibial nerves prior to first session. Integrated electromyography EMG recorded before after sessions evaluate neuromuscular disorders. patients hospitalized receive rehabilitation with 2 weeks. was performed two 60 min sessions. All cases demonstrated severe impairment according result CMAP. integrated measurements antagonistic decreased training. manual testing (MMT) scores each slightly increased intervention Case 2(tibialis anterior, 2+; gastrocnemius muscles, 2− 2; extensor digitorum longus, hallucis 1 3). MMT also except 3 (tibialis 2). These contractions CMAP Even though amplitude CMAPs low, may provide movements by reducing contraction via computer processing. enhance movement coordination through motor learning feedback.
