Our objective was to advance the technologies for restoring walking abilities to veterans paralyzed by spinal cord injury. We developed a device that supports the knee against collapse during standing and walking and that works together with activation of the user's own paralyzed muscles by functional neuromuscular stimulation. This knee mechanism was designed to support the user without the need for muscle stimulation, thus reducing muscle activity and delaying tiredness. The results show that it is possible to use the knee mechanism in a hybrid neuroprosthesis, a system combining bracing with functional neuromuscular stimulation for walking in paraplegia.
