The improvement effects of active dorsiflexion of the ankle joint of the hemiplegic lower extremity through the application of weak electrical stimulation below the contraction threshold of the M.tibialis anterior (Sub-threshold Therapeutic Electrical Stimulation: STES) on the common peroneal nerve were investigated. During the delivery of STES, the active range of motion during dorsiflexion increased significantly in four of the six hemiplegic patients in whom active dorsiflexion had been observed without STES. After one month of active dorsiflexion exercise using this stimulation method, the active range of motion had clearly increased for all four hemiplegic patients in whom active dorsiflexion had not been observed without STES. Furthermore, a hemiplegic patient in whom active dorsiflexion had not been observed without STES was able to perform active dorsiflexion without STES after one year of active dorsiflexion exercise with STES. The results of this study demonstrate the feasibility of improving the active dorsiflexion motion of the ankle joint of the hemiplegic lower extremity through this stimulation method.
