Summary

This study tests whether brief periods of breathing low oxygen can improve leg strength and walking in people with chronic spinal cord injury. Thirty adults with incomplete spinal cord injury will inhale low oxygen for short sessions over time. Researchers will measure walking endurance and speed to see if this simple approach helps recovery.
