A multi-centric randomized controlled trial to be conducted at two sites, department of phyhysiotherapypy, Punjabi University, Patiala and rehabilitation department, Indian Spinal Injury Centre, New Delhi, India.

To determine the effectiveness of activity-based therapy in comparison with surface spinal stimulation (SSS) in traumatic incomplete spinal cord injury (SCI) with special reference to locomotion-a central pattern generator controlled function.

A major goal for many patients after SCI is to regain the function of locomotion. It is crucial that rehabilitation strives to maximize locomotor ability and functional recovery after SCI. Experimental evidence of improvement in stepping and motor control after activity-based training in animal models and human SCI has been translated into clinical neuro-rehabilitation.

Control group participants will undertake an intensive 24-week duration thrice weekly program of activity-based therapy. In addition to this the participants in experimental group will also receive a session of 45 minutes of SSS on thrice weekly basis. The primary analysis for our study will be at 24 weeks. Linear regression will be used to determine the mean between-group differences and 95% confidence interval for all continuous outcomes using baseline scores and group allocation as covariates.

The primary outcome measure is improvement in the level of walking index for SCI-II. The secondary outcome measures are modified Ashworth scale, Penn spasm frequency score, spinal cord independence measure-III, SCI functional ambulation inventory, Hoffman's reflex, somatosensory evoked potential, and American Spinal Injury Association Impairment Scale scores.

An insight into training-induced mechanisms will be of great importance to fine tune such combined treatments and vindicate their efficacy in restoration of locomotion and functional activities in individuals with SCI.
