目的：描述截肢者活动度预测(C)(AMP)工具的研制，以测量使用假体(AMPPRO)和不使用假肢(AMPnoPRO)的截肢者的步行能力，并测试其可靠性和效度。设计：采用已知组群方法进行测量研究，与现有测量方法同时进行。地点：学术医学中心。参与者：完成假肢训练的191名截肢者，24名可靠性研究(平均年龄+/-标准差，68.3+/-17.9y，范围，28-99y)和167名效度研究的受试者54.8+/-8.6岁；主要观察指标：评委内和评委间的信度；已知组方法的结构效度；与6分钟步行试验、合并症指数、年龄和截肢时间比较的同时效度；控制其他因素后与6分钟步行试验的预测效度比较。结果：接受假肢和不戴假肢的受试者，评委间信度为0.99；AMPnoPRO(P
Objectives: To describe the development of the Amputee Mobility Predictor(C) (AMP) instrument designed to measure ambulatory potential of lower-limb amputees with (AMPPRO) and without (AMPnoPRO) the use of a prosthesis, and to test its reliability and validity.Design: Measurement study using known groups method and concurrence with existing measures.Setting: Academic medical center.Participants: A convenience sample of 191 lower-limb amputee subjects who had completed prosthetic training, 24 in the reliability study (mean age +/- standard deviation, 68.3 +/- 17.9y, range, 28-99y) and 167 in the validity study (mean age, 54.8 +/- 8.6y; range, 18-100y).Interventions: Not applicable.Main Outcome Measures: Intra- and interrater reliability; construct validy by known groups method; concurrent validity by comparisons with 6-minute walk test, Comorbidity Index, age, and time since amputation; predictive validity by comparison with 6-minute walk test after controlling for other factors.Results: Interrater reliability was.99 for subjects tested with and without their prosthesis; intrarater reliability was .96 and .97. Both the AMPnoPRO (P
