Summary

This study looked at how sleep apnea and low oxygen levels affect muscle strength and breathing in people with chronic spinal cord injury. Thirty adults with neck-level spinal cord injuries were tested using hand grip strength and muscle activity measurements. The goal was to understand if sleep apnea makes muscle weakness worse, which could guide future treatments.
