| Research Abstract |
This study was performed to determine whether gait-related imaginary and visual feedback could change a cortical activation pattern during robot-aided gait in normal healthy subjects and SCI patients. Eight healthy volunteers and 4 patients with chronic SCI (2 complete paraplegia and 2 incomplete quadriplegia) were included in this study. We measured the cortical activation of the motor area during robot-aided gait by means of a near-infrared spectroscopic imaging system. The subjects performed actual and imaginary movement of their lower extremities in several ways. In both normal subjects and incomplete SCI patients, small cortical activations were observed during imaginary leg movement, but the patterns of activation during the active assisted movement and imaginary leg movement. Despite these findings, cortical activation was observed under the mirror visual feedback in the same patients.
