The main objective of this study is to determine the effectiveness of a new treatment regime that uses a neuroprosthesis for the improvement and recovery of grasping functions in persons with spinal cord injuries (SCI). This treatment has been shown to be useful for stroke patients with hemiplegic arm in the recovery of reaching and grasping 1, and our preliminary work indicates that this may also be the case with SCI patients 3. Further, aside from the potential of promoting voluntary grasp in SCI patients, this novel therapeutic approach may also impact the way service is currently delivered in SCI rehabilitation settings.
