High Intensity Exercise in Incomplete SCI

About this trial

This trial is enrolling individuals with chronic incomplete spinal cord injuries to study the effect of high-intensity exercise on walking speed. Previous studies have shown that high-intensity stepping (e.g. overground walking or locomotor training on a treadmill) leads to increased walking ability when compared to low-intensity training. Improvements in walking will also be compared between participants with different degrees of nerve and muscle activity, cardiovascular (heart) function, or genetic characteristics. If selected for the trial, participants will be randomly assigned to one of two groups; 1) a high-intensity (30 sessions of walking related activities for 40 minutes with heart rate close to 80% of reserve) or 2) a low-intensity group (control group, same exercise duration but with heart rate closer to 30% to 40% of reserve).
