目的：开发一种有效且可靠的足优势临床表现测量方法。设计：重复测量的前瞻性横断面研究。地点：实验室。参与者：总共 175 名年龄 16 至 37 岁的健康男性和女性受试者。干预措施：总共 12 项下肢功能执行熟练和非熟练任务。主要结果测量：所选测量的内部一致性和可靠性。结果：采用最大方差旋转的主成分因子分析导致任务被分为 3 个特征值大于 1 的成分，这解释了 55% 的方差。我们发现 4 项技能组成任务的清单可以可靠地确定立足点。源自 Cronbach's alpha 的内部一致性对于熟练任务产生的值为 0.819。 4 项技能任务中的 3 项被发现具有出色的可靠性 (>0.75)，几乎完全一致。结论：考虑到人类大脑半球功能、肢体形态和运动表现参数的正常偏侧性变化，确定足优势在康复环境中非常重要。这项研究开发了一份技能表现任务清单，以可靠地确定立足点。确定了四项双边任务，这些任务具有出色的重测可靠性和高度的内部一致性，并被推荐作为立足点的全球决定因素。总理报告 2010；2:835-841
Objective: To develop a valid and reliable clinical performance measure of foot dominance.Design: Prospective cross-sectional study with repeated measures.Setting: Laboratory. Participants: A total of 175 healthy male and female subjects ages 16 to 37 years.Interventions: A total of 12 lower limb functional performance skilled and unskilled tasks.Main Outcome Measure: Internal consistency and reliability of selected measures.Results: Principal components factor analysis with varimax rotation resulted in tasks being grouped into 3 components with Eigen values greater than 1, which explained 55% of the variance. An inventory of 4 skilled component tasks was found to reliably determine footedness. Internal consistency derived from Cronbach's alpha produced a value of 0.819 for the skilled tasks. Three of the 4 skilled tasks were found to have excellent reliability (>0.75) with almost perfect agreement.Conclusions: Determining foot dominance is important in a rehabilitation setting, considering the normal laterality variation in cerebral hemisphere function, limb morphology, and motor performance parameters encountered in humans. This study developed an inventory of skilled performance tasks to reliably determine footedness. Four bilateral tasks were identified that had excellent test-retest reliability and high internal consistency and are recommended as global determinants of footedness. PM R 2010;2:835-841
