In-home Telerehabilitation for Quadriplegic Hand Function

1. To evaluate improvements in hand function in stable, cervical spinal cord injured (SCI) subjects treated with functional electrical stimulation (FES)-assisted exercise; 2. To compare the information obtained from existing qualitative and quantitative hand function tests with newly developed tests of sensorimotor performance. Hypotheses: 1. the performance of tasks representative of activities of daily living (ADL) will improve with daily tele-supervised exercise of the affected hand. 2. The improvements will be greater in one exercise protocol than the other, the protocols being a) FES-assisted exercise on a workstation, b) cyclical FES, weight training and precision tasks. 3. Scores derived from quantitative data obtained from sensors on the workstation will correlate with the qualitative scores of the primary outcome measure, the ARAT hand function test.
