The Rivermead Mobility Index is used to measure mobility in patients with head injury or stroke. The purpose of the study was to examine construct validity, predictive validity, and the responsiveness of the Rivermead Mobility Index in stroke patients. Thirty-eight stroke inpatients participated in the study. The Rivermead Mobility Index, the Barthel Index, and the Berg Balance Scale were administered at admission to the rehabilitation ward and at discharge. The results showed that the Rivermead Mobility Index fulfilled the Guttman scaling criteria (coefficients of reproducibility > 0.9, coefficients of scalability > 0.7). The Rivermead Mobility Index scores were highly correlated with the Barthel Index scores (Spearman rs > 0.6) and the Berg Balance Scale scores (Spearman rs > = 0.8, all ps < 0.001). The Rivermead Mobility Index score at admission was closely correlated with the Barthel Index score at discharge (Spearman r = 0.77, p < 0.001). About 76% (29) of the subjects improved by more than 3 Rivermead Mobility Index points (median = 5) during their stay. The relationship between the change in score of the Rivermead Mobility Index and the Barthel Index was fair (Spearman r = 0.6, p < 0.001). These results indicate that the Rivermead Mobility Index is valid and sensitive to change over time. It is therefore a useful scale for the assessment of mobility in stroke patients.
里弗米德运动指数用于测量脑损伤或中风患者的运动能力。本研究的目的是检验里弗米德运动指数在中风患者中的结构效度、预测效度和反应性。38名中风住院患者参与了该研究。在康复病房入院时和出院时分别进行里弗米德运动指数、巴氏指数和伯格平衡量表评估。结果显示，里弗米德运动指数符合古特曼量表标准（再现性系数>0.9，可扩展性系数>0.7）。里弗米德运动指数得分与巴氏指数得分高度相关（斯皮尔曼等级相关系数rs>0.6），与伯格平衡量表得分也高度相关（斯皮尔曼等级相关系数rs>=0.8，所有p值<0.001）。入院时的里弗米德运动指数得分与出院时的巴氏指数得分密切相关（斯皮尔曼等级相关系数r = 0.77，p<0.001）。约76%（29名）受试者在住院期间里弗米德运动指数得分提高超过3分（中位数=5分）。里弗米德运动指数得分变化与巴氏指数变化之间的关系尚可（斯皮尔曼等级相关系数r = 0.6，p<0.001）。这些结果表明，里弗米德运动指数是有效的，且对随时间的变化敏感。因此，它是评估中风患者运动能力的一个有用量表。
