Breathing trick may boost brain power in MS patients

This study tests whether a breathing technique called Acute Intermittent Hypoxia (AIH) can help improve arm and hand function in people with multiple sclerosis (MS). Participants will breathe short bursts of low-oxygen air while researchers measure brain signals and muscle strength. The goal is to understand how AIH affects the brain and spinal cord, not to cure MS. About 22 adults with relapsing-remitting or secondary progressive MS will take part.
