Abstract

The Nucleus 22-channel implantable hearing prosthesis (Cochlear Pty. Ltd., Lane Cove, Sydney, Australia) has been modified by computer programming (MOCQ, Inc., Scituate, Mass. USA) into a functional electrical stimulator. Individual or multiple channels can be sequenced and adjusted for their amplitude, width and frequency of the pulse so that activation of single and multiple nerves can be achieved. Sciatic nerve branches (lateral and medial) of anesthetized rabbits were stimulated to produce single contractions or co-contraction at the ankle and simultaneous bilateral joint movements. The spiral (Helix) electrode was also found suitable in these experiments. The external equipment is being re-designed for a wearable ambulation unit to be used in paraplegic subjects.
