Breathing trick and back zap boost walking after spinal injury

This study tested a new approach to help people with spinal cord injury walk better. Participants received brief sessions of mild low-oxygen air (acute intermittent hypoxia) combined with gentle electrical stimulation on the back, plus walking practice. The goal was to see if this combination improves walking distance and speed more than walking practice alone. The study included 14 adults with spinal cord injury and compared the new method to a sham treatment.
