| Research Abstract |
Objective : The effect on spastic hemiparesis of a hybrid therapy consisting of functional electrical stimulation (FES) and block therapy was examined. Design : Nonblinded randomized controlled trial. Participants : Consecutive sample of 16 stroke patients, recruited more than 1 year after stroke, had spastic upper-extremity impairments. Interventions Experimental patients underwent hybrid FES therapy on their Extensor Carpi Radialis Longs & Brevis (ECRL & B), Extensor Digitorum Communis (EDC), and Extensor Indicis Proprius muscles once or twice a week for 4 months after motor point blocks at the spastic finger flexor muscles. Surface electrodes picked up the EMG signal and stimulated those muscles in proportion to the integrated EMG signal obtained by FES device. Main Outcome Measures : The root mean square (RMS) of the ECRL and EDC maximum voluntary EMGs, active ROM of wrist extension, finger extension (MP, PIP), Modified Ashworth Scale (MAS) and 2 clinical tests were examined before and after training. Results : RMS, Active ROM, MAS and 2 clinical tests showed marked improvement in all the experimental patients as compared to the controls. Conclusions : The hybrid therapy was effective for chronic patients with spastic hemiparesis. Proprioceptional sensory feedback may have an important role in power-assisted FES therapy.
