 Treadmill therapy has the potential to improve the physical fitness and voluntary function of incomplete-lesion spinal cord injured SCI patients. However, if it is to be offered as a rehabilitation strategy, evidence must be gathered to support its effectiveness. Present methods used to determine the efficacy of treadmill training do not provide accurate means of monitoring changes in physical fitness during the exercise, or to accurately measure the changes in voluntary muscle function which may occur during a training intervention.
