我们每天都会向后走，比如从厨房水槽后退，或者在一辆快速行驶的公共汽车经过时从路边后退。对于患有帕金森病 (PD) 的人来说，这项任务可能尤其困难，因为他们经常因向后移动或受到干扰而跌倒。本研究的目的是评估 PD 患者的倒退行走 (BW)。对 78 名处于 ON 状态的特发性 PD 患者（H&Y 范围：0.5-3）和 74 名年龄和性别匹配的对照者进行了向前行走 (FW) 和 BW 的评估。在 FW 中，与对照组相比，PD 患者的步幅明显更短，摆动百分比更低，站立百分比更高，功能性行走曲线也更低。与 FW 相比，BW 期间两组人的行走速度都明显慢一些，并且获得的支持基础更广泛。此外，在 BW 中，与对照组相比，PD 患者的行走速度明显减慢，步幅更短，摆动百分比更低，双支撑和站立百分比更高，功能性行走曲线更低。患有轻度至中度 PD 的患者 FW 和 BW 均受损，但患有和不患有 PD 的患者之间的 BW 差异更为明显。 (C) 2008 运动障碍协会
We walk backward on a daily basis, such as when backing away from the kitchen sink or stepping back from a curb as a swiftly moving bus passes. This task may be particularly difficult for individuals with Parkinson's disease (PD) who often fall as a result of moving or being perturbed in the backward direction. The aim of this study was to assess backward walking (BW) in individuals with PD. Both forward walking (FW) and BW were assessed in 78 people with idiopathic PD (H&Y range: 0.5-3) in the ON state, and 74 age- and sex-matched controls. In FW, those with PD had significantly shorter strides, lower swing percents, higher stance percents, and lower functional ambulation profiles than controls. Both groups walked significantly slower and with a wider base of support during BW than FW. Additionally, in BW those with PD walked significantly slower with shorter strides, lower swing percents, and higher double support and stance percents, and lower functional ambulation profiles compared with controls. Those with mild to moderate PD have impaired FW and BW, but differences between those with and without PD are more pronounced in BW. (C) 2008 Movement Disorder Society
