This case report explores how respiratory muscle training (RMT) affects sleep quality in a person with a spinal cord injury (SCI). SCI can weaken respiratory muscles, leading to poor sleep. The study examines if RMT can improve sleep quality, using polysomnography (PSG) to measure sleep patterns. A 38-year-old male with cervical SCI underwent 10 weeks of RMT. Before and after the training, his sleep was assessed using PSG, respiratory muscle strength tests, and a subjective sleepiness scale. Results showed improvements in sleep quality and reduced daytime sleepiness after RMT. The findings suggest that improving respiratory activity can positively impact EEG arousal activity during sleep. Reducing arousals leads to less fragmented sleep and better overall sleep quality, which can improve daytime function and reduce issues like excessive sleepiness.
Individuals with SCI who report sleep disturbances or daytime sleepiness should undergo thorough medical evaluation, including polysomnography.
RMT may be a beneficial intervention to improve sleep quality, particularly for individuals with SCI who exhibit respiratory muscle weakness.
Larger-scale studies are needed to confirm the effects of RMT on sleep and arousal indices in the SCI population.
