Effects of Breathing Mild Bouts of Low Oxygen on Limb Mobility After Spinal Injury

Participants will breathe intermittent low oxygen via air generators. The generators will fill reservoir bags attached to a non-rebreathing face mask. Oxygen concentration will be continuously monitored to ensure delivery of fraction of inspired oxygen (FiO2) = 0.10±0.02 (hypoxia). Participants will receive treatment on 5 consecutive days.
