Parkinson's disease (PD) is a neurodegenerative condition characterized by motor dysfunction and various types of non-motor impairments. The reaction time and movement time are reported to become more severe delayed in worse PD patients. Most tools for evaluating motor impairment are limited by relying on subjective observations and being qualitative in design. The aim of this study was to investigate trunk rolling performance in PD patients by using a recently developed system to detect turning in bed.
The study included 20 PD patients and 42 healthy controls. A mattress mobility detection system was employed for quantitative measurements. Each test session consisted of subjects starting by lying in a supine position on a bed and rolling 10 times onto their left side and 10 times onto their right side. Strain gauges mounted under the feet of the bed recorded changes in the center of pressure (CoP).
For turning back, the patients compared with the controls had significantly longer movement time (P = 0.017), longer time to peak counteraction (P = 0.001), larger ratio of peak counteraction to movement time (P = 0.006), shorter CoP displacement (P < 0.0001), slower turning speed (P = 0.000), weaker peak counteraction (P = 0.013), and smaller ratio of peak counteraction to weight (P = 0.032). Results for turning over were similar except there was no significant difference in the ratio of peak counteraction to weight.
The mattress mobility detection system was useful for objectively assessing trunk rolling performance of PD patients. Improved assessment of trunk function in PD patients could lead to better treatments and improved rehabilitation procedures.
帕金森病（PD）是一种神经退行性疾病，其特征为运动功能障碍和多种非运动障碍。研究报道，病情越严重的 PD 患者，其反应时间和运动时间延迟越严重。大多数评估运动障碍的工具都受到限制，因为它们依赖于主观观察，并且设计上是定性的。本研究旨在使用最近开发的检测床上翻身的系统来研究 PD 患者的躯干滚动性能。
该研究纳入了 20 名 PD 患者和 42 名健康对照者。使用床垫活动检测系统进行定量测量。每次测试时，受试者先仰卧在病床上，然后向左侧翻滚 10 次，再向右侧翻滚 10 次。安装在床脚的应变片记录了压力中心（CoP）的变化。
对于向后翻身，患者与对照组相比，运动时间显著延长（P=0.017），达到峰值对抗时间显著延长（P=0.001），峰值对抗与运动时间的比值显著增大（P=0.006），CoP 位移显著减小（P<0.0001），转身速度显著减慢（P=0.000），峰值对抗显著减弱（P=0.013），峰值对抗与体重的比值显著减小（P=0.032）。对于翻身动作，结果相似，只是峰值对抗与体重的比值没有显著差异。
床垫活动检测系统可用于客观评估 PD 患者的躯干滚动性能。对 PD 患者躯干功能的评估得到改善，可能会带来更好的治疗和改进的康复程序。
