Intermittent Hypoxia Therapy for Spinal Cord Injury
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial tests whether breathing low-oxygen air for short periods, known as Acute Intermittent Hypoxia (AIH) therapy, can help individuals with incomplete spinal cord injuries improve leg strength and walking ability. Researchers aim to determine if these brief low-oxygen sessions can strengthen leg muscles and enhance reflexes. Two groups will be compared: one will breathe low-oxygen air, while the other will breathe normal room air as a control. Individuals with incomplete spinal cord injuries who can take a step without assistance might be suitable for this study. As an unphased trial, this study offers a unique opportunity to explore innovative treatments that could enhance mobility and quality of life.
Will I have to stop taking my current medications?
The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.
What prior data suggests that this protocol is safe for spinal cord injury patients?
Studies have shown that acute intermittent hypoxia (AIH) is generally safe and well-tolerated. Research indicates that AIH sessions can improve movement abilities without causing major side effects. For example, one study found that using oxygen levels as low as 9% was safe for people with long-term conditions like traumatic brain injuries.
In people with spinal cord injuries, AIH has been linked to temporary improvements in breathing and limb strength. The treatment involves breathing short bursts of low oxygen, which appears to quickly boost strength and coordination. Although some heart and blood vessel effects require further research, AIH is considered a safe option for enhancing nerve function.12345Why are researchers excited about this trial?
Researchers are excited about Intermittent Hypoxia Therapy for spinal cord injury because it offers a novel approach by using short bouts of low oxygen to potentially enhance recovery. Unlike traditional treatments such as physical therapy or medications that focus on managing symptoms, this therapy might stimulate neural pathways and improve motor functions directly. The method is non-invasive and works through a new mechanism of action, which could provide significant benefits without the need for surgical intervention. This innovative approach is especially promising because it targets the body's natural adaptive responses to low oxygen, potentially leading to improved outcomes for individuals with chronic spinal cord injuries.
What evidence suggests that this trial's treatments could be effective for spinal cord injury?
This trial will compare Acute Intermittent Hypoxia (AIH) with a sham treatment. Research has shown that breathing low-oxygen air for short periods, known as AIH, can improve leg function in individuals with partial spinal cord injuries in the neck area. Studies have found that AIH boosts leg strength and walking ability. This method activates the nervous system and strengthens muscles, offering hope for those with motor-incomplete spinal cord injuries seeking to enhance leg strength and mobility.678910

Are You a Good Fit for This Trial?
This trial is for adults aged 18-75 with incomplete spinal cord injury from C2-L5, medically stable and able to take a step without help. It's been over 6 months since their injury. People can't join if they have heart or lung issues, are in physical therapy, have severe pain or infections, fractures due to osteoporosis, leg nerve damage, cognitive impairment (score <24 on Mini-Mental), are pregnant or at risk of frequent autonomic dysreflexia.Inclusion Criteria

What Are the Treatments Tested in This Trial?
Interventions
- Acute Intermittent Hypoxia
- SHAM - Intermittent Room Air
Trial Overview
The study tests how low oxygen periods (AIH) affect leg muscle control and strength in people with cervical spinal cord injuries compared to normal air breathing (SHAM). The goal is to see if AIH improves voluntary leg strength, reflexes in the legs, and walking ability.
How Is the Trial Designed?

Treatment groups
Active Control
Placebo Group
Subjects with chronic, motor-incomplete SCI will breath mild bouts of low oxygen. Intervention: AIH - Intermittent Hypoxia - hypoxia air mixture Dosage: 10% oxygen Frequency: 1.5 minutes bouts of low oxygen with 1.0 minute intervals of room air Duration: 38 minutes
Subjects with chronic, motor-incomplete SCI will breath mild bouts of room air. Intervention: SHAM - Intermittent Room Air - room air mixture Dosage: 21% oxygen Frequency: 1.5 minutes bouts of room air with 1.0 minute intervals also of room air Duration: 38 minutes
