Abstract | We present the modelling and design of an implantable system with monopolar half-cuff for selective stimulation of fibres within the superficial region of the human common peroneal nerve. A half-cuff electrode is capable of making a long term selective activation, mainly of those muscles that contribute to strong dorsal flexion and moderate eversion of the hemiplegic foot. One of the modelling objectives was to detemine the three dimensional spread of the electric field that would be generated by the half-cuff within the deep peroneal branch of the nerve by the half-cuff. Moreover, the extent of initial excitation of the nerve fibres within the superficial region was predicted. For this purpose a total equivalent driving function at six positions within the half-cuff was calculated. The modelling objective was also to introduce a time delay between the cathodic and anodic parts of the stimulating pulse pair, mainly to predict eliciting more gradual recruitment of motor units. | |
