The goal of this contract is to develop Functional Neuromuscular Stimulation (FNS) systems to restore coordinated, directed upper extremity function by synergistically controlling stimulated and voluntary movements in tetraplegic individuals with high, middle, and low cervical injuries. Evaluation of these FNS systems will be conducted in human subjects who have paralyzed upper extremities as a result of upper motor neuron lesions. The contract will consist of a base contract period of 30 months, followed by one possible 30 month option period.
