Abstract
Epidural spinal cord stimulation has been demonstrated to help the recovery of walking abilities of patients with incomplete spinal cord injury when combined with partial weight bearing therapy. However, no work has been done in studying the dynamics of these signals generated with and without stimulation. In this paper, we show that the underlying dynamics of such signals is chaotic. We also estimate the correlation dimension of these signals and show the difference in the dynamics of gait with and without stimulation using the kinematic data of right knee and right hip. The correlation dimension thus estimated can be used to evaluate the efficiency of epidural spinal cord stimulation in patients.
