Combining breathing therapies to help restore breathing after neck-level spinal cord injury

Official title: Combinatorial respiratory rehabilitation approaches to enhance breathing recovery after cervical spinal cord injury

Funded at University of Florida · NIH-11335738 · Data updated 2026-11-12

This project will see whether brief bursts of low oxygen combined with breathing exercises or exercise can help people with chronic neck spinal cord injuries breathe better.

Who could benefit from this research

Could help

Ideal candidates are people with chronic (not new) incomplete cervical spinal cord injuries who have weakened breathing but retain some spinal nerve function and can participate in in-person therapy sessions.

Less likely to help

People with complete cervical spinal cord injuries with no spared respiratory pathways, those in the acute phase of injury, or those who cannot safely tolerate low-oxygen or higher-CO2 exposures are unlikely to benefit.

What this research studies

You would come to the research center for guided sessions that pair short periods of lowered oxygen (therapeutic acute intermittent hypoxia) with either physical exercise or controlled breathing with slightly higher carbon dioxide. The team will measure how your breathing muscles respond, check blood gases, and monitor breathing during daily activities before and after a course of treatments. Treatments are given repeatedly over weeks so researchers can tell if breathing gets stronger and more reliable over time. The aim is to strengthen any spared nerve pathways to improve everyday breathing ability.

Why it matters

Potential benefit: If successful, this approach could increase breathing strength and reduce breathing problems for people with chronic cervical spinal cord injuries.

How similar studies have gone: Previous animal studies show that therapeutic acute intermittent hypoxia can improve breathing in acute injury models and that combining intermittent hypoxia with task-specific training helps other motor systems in chronic spinal cord injury, but pairing it specifically with respiratory training in chronic cervical injury is a newer approach.
