本研究的目的是评估完全性脊髓损伤受试者的睡眠模式和主诉，以及周期性肢体运动（PLM）和不宁腿综合征（RLS）。志愿者被提交了两个多导睡眠图（牛津Medilog SAC系统-脑电图，肌电图，EOC）：(1)基础夜，当志愿者到达睡眠中心时，(2)在最大体能测试后（Cybex Met 300/增加12.5瓦/2分钟，直到精疲力竭）。对11名T7-T12间完全性脊髓损伤的志愿者进行评估。采用配对学生t检验（总睡眠时间）和Wilcoxon配对检验（睡眠阶段变化、睡眠中醒来次数、进入快速眼动睡眠潜伏期和腿部运动- plm +RLS）对数据进行分析。将锻炼前一晚的睡眠记录与锻炼后一晚（12小时）的睡眠记录进行比较，发现所有睡眠参数都显著减少。结果表明，体育锻炼可以改善脊髓损伤志愿者的睡眠模式。我们特别注意到，体力活动后的PLM和RLS在睡眠期间受到抑制。
The purpose of the present study was to evaluate sleep patterns and complaints, and Periodic Limb Movement (PLM) and the Restless Legs Syndrome (RLS) in subjects with complete spinal cord injury. Volunteers were submitted to two polysomnograms (Oxford Medilog SAC system - EEG, EMG, EOC): (1) basal night, when the volunteer arrived at the Sleep Center, and (2) after a maximal physical test (Cybex Met 300/increase of 12,5 watts/2 min until exhaustion). Eleven volunteers with complete spinal cord injury between T7-T12 were evaluated. Data were analyzed by the paired Student's t test (total sleeping time) and by the Wilcoxon matched paired test (change of sleep stages, number of awakenings during sleep, latency to REM sleep and leg movements-PLM+RLS). Comparison of sleep recordings from the night before with that from the night after (12 h) practice of physical activity, showed a significant reduction in all of the sleep parameters. The results indicate that physical activity improves the sleep patterns of spinal cord injured volunteers. In particular, we noticed that PLM and RLS after physical activity were inhibited during sleep.
