Study Summary

This trial will test if repeatedly breathing low oxygen levels for brief periods can help people with chronic spinal cord injuries to recover some motor function.

Who is the study for?

This trial is for adults aged between 18 and 75 with a chronic spinal cord injury, who can still move their legs voluntarily. They must have had the injury for over a year and be medically cleared to participate. The injury should be non-progressive and located between C2 and T12 on the spine.Check my eligibility

What is being tested?

The study tests whether breathing low oxygen levels in short bursts (intermittent hypoxia) can improve limb movement and enhance nerve pathways in people with chronic spinal cord injuries. It also includes walking exercises and strength training as part of the therapy being examined.See study design

What are the potential side effects?

While not explicitly stated, potential side effects may include discomfort from low oxygen such as headache or dizziness, fatigue from physical exercises, or muscle soreness after strength training.

Trial Design

2Treatment groups

Active Control

Group I: AIH/StrengthActive Control2 Interventions

Subjects with chronic, motor-incomplete SCI receive AIH with strength practice, then AIH with walking practice and compare their efficacy on enhancing strength and/or walking performance.

Group II: AIH/WalkActive Control2 Interventions

Subjects with chronic, motor-incomplete SCI receive acute intermittent hypoxia (AIH) with walking practice, then AIH with strength practice and compare their efficacy on enhancing strength and/or walking performance.
