Epidural Stimulator for Spinal Cord Injury

The overall aim is to assess whether task specific locomotor training and spinal cord electrical stimulation (SCES) can induce neural reorganization of the functionally isolated human spinal cord to improve standing and stepping in individuals with functionally complete SCI. The investigators propose that locomotor training will result in generation of more effective standing and stepping efferent patterns by restoring phase dependent modulation of reflexes and reciprocal inhibition, reducing clonus and mediating interlimb coordination. The investigators propose that the SCES will optimize the physiological state of the spinal cord interneuronal circuitry compromised by compensating for loss of supraspinal input for the retraining of these tasks.
