Disturbances in the circadian activity rhythms (CARs) of inpatients in rehabilitation facilities delay the recovery of physical and mental functions. The purpose of this study is to elucidate the circadian activity rhythms of hospitalized patients in a rehabilitation facilitie using the synthetic periodic regression analysis, and investigate the relationship between their physical activity levels and CARs.An observational study was conducted. A group of thirty-four inpatients participated in the study by wearing wrist-type activity monitors to measure metabolic equivalents (METs). Using synthetic periodic regression analysis, the CARs were analyzed based on the amount of physical activity throughout the day, and the exercise intensity classification of their physical activity was assessed. In the CARs of the inpatients, the mean physical activity level was 1.23 ± 0.09 METs. The maximum amount was 1.36 ± 0.15 METs. The range was 0.30 ± 0.15 METs. The maximum phase time was 11:48 ± 2:31 h. The longer the duration of physical activity over 1.6 METs, the higher the mean, maximum and range of the CARs. Physical activities with a METs level of 1.6 or higher might have an impact on the mean, maximum, and range of circadian activity rhythms in hospitalized patients.

康复机构住院患者的昼夜活动节律紊乱会延迟身心功能的恢复。本研究的目的是使用合成周期回归分析阐明康复机构中住院患者的昼夜活动节律,并研究其身体活动水平与昼夜活动节律之间的关系。
进行了一项观察性研究。一组34名住院患者通过佩戴腕式活动监测器以测量代谢当量(METs)参与了该研究。使用合成周期回归分析,根据全天的身体活动量分析昼夜活动节律,并评估其身体活动的运动强度分类。在住院患者的昼夜活动节律中,平均身体活动水平为1.23±0.09METs。最大值为1.36±0.15METs。范围为0.30±0.15METs。最大相位时间为11:48±2:31小时。身体活动持续时间超过1.6METs越长,昼夜活动节律的平均值、最大值和范围就越高。METs水平为1.6或更高的身体活动可能会对住院患者昼夜活动节律的平均值、最大值和范围产生影响。
