A neuroprosthesis for grasping is a device that can improve or restore the grasping, holding, and releasing functions in persons with SCI 2, 3. The neuroprosthesis applies functional electrical stimulation (FES) to artificially generate a muscle contraction by applying short current pulses to motor nerves innervating muscles. FES can be applied to individuals with incomplete SCI to help them restore functions such as walking and grasping by contracting groups of paralyzed muscles in an orchestrated manner 4. FES was originally envisioned as an intervention that was 'permanent' in nature. In other words, an individual had to wear/use an FES orthotic device at all times if s/he wanted to generate the function that was impaired by SCI 4. Our application of the neuroprosthesis for grasping in this proposal presents a departure from this standard and established approach of FES application. Rather than having people be dependent on the neuroprosthesis to perform their activities of daily living (ADL), we plan to use the neuroprosthesis for grasping as a short-term intervention that will help SCI individuals recover voluntary grasping function. Hence, we believe that those participants who undergo our FES therapy with the neuroprosthesis should be able to perform grasping functions without its use once the treatment program is completed.
