The purposes of this study of 30 patients referred to physical therapy were to describe the reliability of two measures of impairment and a measure of gait performance and to examine the relationships between the impairment and gait measures. The impairments measured were standing balance and muscle strength of the lower extremities, the former with a seven-level ordinal scale and the latter with a hand-held dynamometer. Gait performance was measured using the seven-category scale of the Functional Independence Measure. Interday reliability was acceptable for all three measures, standing balance (weighted Kappa = .95), muscle strength (intraclass correlation coefficients = .871 to .951), and gait (weighted Kappa = .915). A Spearman correlation of .860 was found between balance and gait measures. The correlations between the strengths of various muscle groups and gait were lower (.138 to .581). Multiple regression identified none of the strength scores as offering additional independent explanation of gait performance. Balance, as scored, appears to be a reliable and valid measure worth broader application among hospitalized patients.
本研究纳入30例接受物理治疗的患者，旨在描述两项功能障碍测量指标及一项步态表现测量指标的可靠性，并检验功能障碍指标与步态指标之间的关系。所测量的功能障碍包括站立平衡和下肢肌肉力量，前者采用七级序数量表，后者使用手持测力计。步态表现采用功能独立性测量的七分类量表进行测量。所有三项测量指标的日间可靠性均可接受，站立平衡（加权Kappa系数 = 0.95）、肌肉力量（组内相关系数 = 0.871至0.951）和步态（加权Kappa系数 = 0.915）。平衡指标与步态指标之间的Spearman相关系数为0.860。不同肌肉群力量与步态之间的相关性较低（0.138至0.581）。多元回归分析未发现任何力量得分能够为步态表现提供额外的独立解释。所记录的平衡似乎是一项可靠且有效的测量指标，值得在住院患者中更广泛地应用。
