The Figure-of-8 Walk Test (F8W) is a valid measure of walking skill in older adults with a mobility disability. Use of the F8W in assessing walking skill in persons with Parkinson's disease (PWP) is unknown.
We examined the validity of the F8W by associations with mobility, and cognitive and physical function, and determined the ability of the F8W to discriminate the motor skill of walking in PWP from that of older adults (OA).
Participants, PWP (n = 60) and OA (n = 34) performed the F8W, usual straight path walking, the Montreal Cognitive Assessment (MoCA), and the Late-Life Function and Disability Instrument (LLFDI).
Among PWP, F8W time and steps related to: usual gait speed (r = -0.660, -0.650); stride time variability (r = 0.377, 0.438); cognition (r = -0.293, time only); and physical function (r = -0.532, - 0.619), all < .05. Area under the curve (AUC) analyses demonstrated greater sensitivity and specificity of F8W performance (0.811, 0.790) compared to usual gait speed (0.729) to recognize the motor skill of walking in PWP from that of OA.
The F8W is a valid indicator of the motor skill of walking in PWP. Use of the F8W may uncover walking difficulties not identified by usual gait speed.
8字步行测试（F8W）是评估有行动障碍的老年人步行技能的有效方法。F8W在评估帕金森病患者（PWP）步行技能方面的应用尚不清楚。
我们通过与行动能力、认知和身体功能的关联来检验F8W的有效性，并确定F8W区分PWP与老年人（OA）步行运动技能的能力。
参与者，即PWP（n = 60）和OA（n = 34）进行F8W、常规直线步行、蒙特利尔认知评估（MoCA）和晚年功能与残疾量表（LLFDI）。
在PWP中，F8W时间和步数与以下因素相关：常规步态速度（r = -0.660，-0.650）；步幅时间变异性（r = 0.377，0.438）；认知（r = -0.293；仅时间）；以及身体功能（r = -0.532，-0.619），所有相关性均<0.05。曲线下面积（AUC）分析表明，与常规步态速度（0.729）相比，F8W表现（0.811，0.790）在识别PWP与OA的步行运动技能方面具有更高的敏感性和特异性。
F8W是PWP步行运动技能的有效指标。使用F8W可能会发现常规步态速度未识别出的步行困难。
