Overview

Effects of Caffeine and Intermittent Hypoxia on Leg Function in Human Spinal Cord Injury

Status:
Active, not recruiting
Trial end date:
2021-12-01
Target enrollment:
0
Participant gender:
All
Summary
Accumulating evidence suggests that repeatedly breathing low oxygen levels for brief periods (termed intermittent hypoxia) is a safe and effective treatment strategy to promote meaningful functional recovery in persons with chronic spinal cord injury (SCI). The goal of the study is to understand how caffeine may augment the effects of intermittent hypoxia on motor function and spinal plasticity (ability of the nervous system to strengthen neural pathways based on new experiences) following SCI.
