To examine the test-retest reliability, convergent and predictive validity and responsiveness of the modified Emory Functional Ambulation Profile (mEFAP) in assessing gait function in stroke patients undergoing rehabilitation.
Forty subacute stroke inpatients were enrolled in the validity and responsiveness study. Twenty chronic patients participated in the reliability study.
Rehabilitation department of a medical centre.
In the validity and responsiveness study, patients were tested using the mEFAP, 10-m walking speed test, Barthel Index and Rivermead Mobility Index at admission and at discharge. For the reliability study, the patients completed the mEFAP twice one week apart.
The patients' performances on the mEFAP were moderately to highly correlated with results of the 10-m walking speed test and Rivermead Mobility Index (absolute correlation coefficients > or = 0.67), indicating good convergent validity. Patients' performance on the mEFAP at admission was moderately correlated with the Barthel Index and Rivermead Mobility Index scores at discharge (Spearman's rank correlation coefficients = -0.52 and -0.78, respectively), indicating good predictive validity. The standardized response mean of the mEFAP was 1.1 (P < 0.0001), suggesting good responsiveness. The intraclass correlation coefficient ICC(3,1) for the mEFAP was 0.997, indicating excellent test retest reliability.
Our results provide strong evidence that the mEFAP has good reliability, validity and responsiveness for assessing stroke patients undergoing rehabilitation. The mEFAP is a useful scale for measuring walking function and recovery in stroke patients.
探讨改良版埃默里功能步行量表（mEFAP）在评估接受康复治疗的中风患者步态功能时的重测信度、收敛效度、预测效度及反应度。
40名亚急性中风住院患者参与效度和反应度研究。20名慢性患者参与信度研究。
某医疗中心康复科。
在效度和反应度研究中，患者在入院时和出院时接受mEFAP、10米步行速度测试、巴氏指数和里弗米德活动指数测试。在信度研究中，患者在相隔一周的时间内两次完成mEFAP测试。
患者在mEFAP上的表现与10米步行速度测试及里弗米德活动指数的结果呈中度至高度相关（绝对相关系数≥0.67），表明具有良好的收敛效度。患者入院时mEFAP的表现与出院时巴氏指数及里弗米德活动指数得分呈中度相关（斯皮尔曼等级相关系数分别为-0.52和-0.78），表明具有良好的预测效度。mEFAP的标准化反应均值为1.1（P<0.0001），表明具有良好的反应度。mEFAP的组内相关系数ICC(3,1)为0.997，表明具有出色的重测信度。
我们的结果提供了有力证据，表明mEFAP在评估接受康复治疗的中风患者时具有良好的信度、效度和反应度。mEFAP是测量中风患者步行功能和恢复情况的有用量表。
