目的：评价加速度计量仪测量上肢康复效果的信度和效度。设计：验证性研究。地点：社区记录的数据。参与者：连续强制诱导运动疗法(CIMT)患者(n=10)和志愿社区居民(n=10)。干预：所有研究参与者在治疗前和治疗后立即在实验室外佩戴加速度计3天，或在大致相同的非治疗期间(对照组)。主要观察指标：参与者在每只手臂、胸部和受影响更严重的腿上佩戴加速度计，并完成运动活动日志(MAL)，这是对真实手臂使用情况的半结构化访谈。结果：转换后的加速度计记录的重测信度大于0.86。在接受CIMT治疗的患者中，改变的多损伤与少损伤的手臂记录的比率也有很大的增加(d‘=0.9，P
Objective: To evaluate the reliability and validity of accelerometry for measuring upper-extremity rehabilitation outcome.Design: Validation study.Setting: Data recorded in the community.Participants: Consecutive Constraint-Induced Movement therapy (CIMT) patients (n=10) and volunteer community residents with stroke (n = 10). All participants were more than I year poststroke and had mild to moderate motor impairment of the more affected arm.Intervention: All study participants were asked to wear accelerometers outside the laboratory for 3 days immediately before and after treatment, or for an approximately equivalent no-treatment period (controls).Main Outcome Measures: Participants wore an accelerometer on each arm, the chest, and the more affected leg and completed the Motor Activity Log (MAL), which is a semi-structured interview of real-world arm use.Results: Test-retest reliability of transformed accelerometer recordings was greater than .86. There was also a large increase in the ratio of transformed more- to less-impaired arm recordings in CIMT therapy patients (d'=0.9, P
