To evaluate functional mobility and postural control in participants with essential tremor (ET).
Cross-sectional cohort study.
Motor performance research laboratory.
Sixteen participants with ET including head tremor (age, 59.4+/-12.0 y), 14 participants with ET and no head tremor (age, 57.1+/-15.9 y), and 28 healthy controls (age, 58.4+/-12.4 y).
Not applicable.
We assessed the Timed Up & Go, time to ascend and descend stairs, Dynamic Gait Index, and Berg Balance Scale (BBS). Participants completed the Activities-specific Balance Confidence Scale and the Human Activity Profile. We assessed postural control using center-of-pressure measures from force platform recordings of quiet standing in 5 conditions.
Participants with ET including head tremor performed worse than controls on all functional mobility performance and self-report measures (P<.05) except the BBS and stair descent time. Mean performance of ET participants without head tremor was intermediate between the other 2 groups. Sway speed measures of postural control showed similar patterns, but no significant group differences in post hoc analysis. There were no statistically significant or clinically important correlations between measures of tremor status and functional mobility status.
Participants with ET show reduced functional mobility, especially those with head tremor.
评估特发性震颤（ET）患者的功能活动能力和姿势控制能力。
横断面队列研究。
运动表现研究实验室。
16名伴有头部震颤的ET患者（年龄59.4±12.0岁），14名无头部震颤的ET患者（年龄57.1±15.9岁），以及28名健康对照者（年龄58.4±12.4岁）。
不适用。
我们评估了计时起立行走测试、上下楼梯时间、动态步态指数和伯格平衡量表（BBS）。参与者完成了特定活动平衡信心量表和人类活动概况。我们使用在5种条件下安静站立时力平台记录的压力中心测量值来评估姿势控制。
伴有头部震颤的ET患者在所有功能活动能力表现和自我报告测量方面（除BBS和下楼梯时间外）均比对照组差（P<0.05）。无头部震颤的ET患者的平均表现介于其他两组之间。姿势控制的摇摆速度测量显示出类似模式，但事后分析中组间无显著差异。震颤状态测量与功能活动能力状态之间无统计学上显著或临床上重要的相关性。
ET患者的功能活动能力下降，尤其是伴有头部震颤的患者。
