Although most patients with Parkinson's disease (PD) present difficulties of bed mobility, the contributing factors to impaired bed mobility in PD are unknown.
To compare bed mobility and muscle strength between PD patients and healthy controls, and investigate the determinants of bed mobility in PD.
Sixteen patients with PD and ten age- and sex-matched healthy controls (HC) were enrolled. Time and pattern to get out of bed to their preferred side at usual speed, muscle torque in lower extremities and motor symptom burden were also measured.
PD exhibited significantly slower speed in bed mobility and lower torque in the hip adductor/abductor/flexor muscle than HC. Slower movement time in PD was correlated with weaker hip adductor torque on the more affected side (Rs = -0.56, p < 0.05) and with higher score in arm rigidity both sides (Rs≥0.79, p < 0.01). There were no significant differences between the categorised movement patterns and movement time in PD (p = 0.31).
Reduced hip adductors torque and severe arm rigidity are associated with slowness of getting out of bed, implying that these components could be used as targets for rehabilitation practice to improve bed mobility in PD.
尽管大多数帕金森病（PD）患者存在卧床移动困难，但导致 PD 患者卧床移动受损的因素尚不清楚。
比较 PD 患者与健康对照者的卧床移动能力和肌肉力量，并探讨 PD 患者卧床移动能力的决定因素。
纳入 16 例 PD 患者和 10 名年龄和性别匹配的健康对照者（HC）。还测量了以通常速度向惯用侧下床的时间和模式、下肢肌肉扭矩和运动症状负担。
PD 患者的卧床移动速度明显较慢，髋关节内收肌/外展肌/屈肌的扭矩也较低。PD 患者的运动时间较慢与患侧较弱的髋关节内收肌扭矩（Rs=-0.56，p<0.05）和双侧手臂僵硬评分较高（Rs≥0.79，p<0.01）相关。PD 患者的分类运动模式和运动时间之间无显著差异（p=0.31）。
髋关节内收肌扭矩降低和手臂僵硬严重与下床速度减慢相关，这表明这些因素可作为康复实践的目标，以改善 PD 患者的卧床移动能力。
