摘　　要：目的明确特殊学校脑瘫儿童步行能量消耗测定的重测信度及测量误差。方法以2010年9月-12月上海浦东新区特殊学校在校脑瘫儿童13例为研究对象,令受试者在往返50 min的步道上连续步行6 min,测定步行距离、休息与步行时的心率,计算物理消耗指数（PCI）。同一受试者在间隔1周后的相同时间、地点、状况下进行重复测定,通过比较前后测定结果之间的相关性确定重测信度和测量误差。结果重测信度检验显示,步行时心率具有良好的信度,步行距离和PCI具有较好的信度（ICC=0.77-0.83）,而休息时心率的信度较低（ICC=0.38）,但是PCI指数的测量误差较大。结论 PCI指数的重测信度较好,但是测量误差较大,易于受到被测者情绪的影响,用于脑瘫儿童步行能耗具有一定的局限性。Objective To determine the retest reliability and measurement error of walking energy consumption measurement in children with cerebral palsy in special school.Methods 13 children with cerebral palsy studying in Shanghai Pudong Special Education School from September to December in 2010 were enrolled in this study.They were asked to walk up and down continuously on a 50-meter-long walking pace in 6 minutes,while the distance of walking and the heart rate of both rest and walking were measured to calculate physical cost index（PCI）.After 1 week,they took the 2nd measurement at the same time,the same location and the same condition.Then the results between the former and the later measurements were compared to identify the retest reliability and measurement error.Results The study showed a good retest reliability in heart rate of walking,distance of walking and PCI（ICC=0.77~0.83）,but a low retest reliability in heart rate of rest（ICC=0.38）.The study also showed a high measurement error in PCI.Conclusion PCI had good retest reliability and high measurement error,and was easily affected by the emotion of the children.So it was limited as a measurement of walking energy consumption in children with cerebral palsy.
