About the study
This study aims to observe the effects of administration of a breathing intervention (Acute Intermittent Hypoxia (AIH)) on spasticity (tightness) in individuals with incomplete Spinal Cord Injury. It is hypothesized that hypoxia will decrease the reflex threshold of the biceps brachii, indicating an increase in spasticity following the AIH.
