This study examined the concurrent validity between gait parameters from the GAITRite walkway and functional balance test commonly used in fall risk assessment. Patients were sampled from one geriatric outpatient clinic. One physiotherapist evaluated the patients on the GAITRite walkway with three repetitions in both single- and dual-task conditions. Patients were further evaluated with Bergs Balance scale (BBS), Dynamic Gait index (DGI), Timed Up and Go (TUG), and Sit To Stand test (STS). Correlations between quantitative gait parameters and functional balance test were analyzed with Spearman's rank correlations. Correlations strength was considered as follows: negligible <0.1, weak 0.10-0.39, moderate 0.40-0.69, and strong ≥0.70. We included 24 geriatric outpatients in the study with a mean age of 80.6 years (SD: 5.9). Patients received eight (SD: 4.5) different medications on average, and seven (29.2%) patients used walkers during ambulation. Correlations between quantitative gait parameters and functional balance test ranged from weak to moderate in both single- and dual-task conditions. Moderate correlations were observed for DGI, TUG, and BBS, while STS showed weak correlations with all GAITRite parameters. For outpatients analyzed on the GAITRite while using walkers, correlations showed no clear pattern across parameters with large variation within balance tests.
本研究检验了GAITRite步道的步态参数与跌倒风险评估中常用的功能平衡测试之间的同时效度。患者来自一家老年门诊。一名物理治疗师在GAITRite步道上对患者进行评估，单任务和双任务条件下均重复三次。患者还接受了伯格平衡量表（BBS）、动态步态指数（DGI）、定时起立行走测试（TUG）和坐立测试（STS）。采用Spearman等级相关分析定量步态参数与功能平衡测试之间的相关性。相关性强度分类如下：可忽略<0.1、弱0.10 - 0.39、中等0.40 - 0.69、强≥0.70。本研究纳入了24名老年门诊患者，平均年龄80.6岁（标准差：5.9）。患者平均服用八种（标准差：4.5）不同药物，七名（29.2%）患者在行走时使用助行器。在单任务和双任务条件下，定量步态参数与功能平衡测试之间的相关性从弱到中等。DGI、TUG和BBS观察到中等相关性，而STS与所有GAITRite参数均显示弱相关性。对于在使用助行器时在GAITRite上进行分析的门诊患者，相关性在各参数间无明显模式，平衡测试中变化较大。
