目的：确定社区居住的下肢截肢者自我报告活动的准确性。设计：描述性研究。设置：区域假肢门诊服务。参与者：77名单侧下肢截肢者，假肢康复后至少6个月。干预：不适用。主要结果测量：测量的活动计数（步数/分钟）和自我报告的活动（休息，低，中，高）在15分钟的时间间隔超过1 week被记录为每个participant.Results：参与者平均每天3063 +/- 1893步。在上午9：00至晚上9：00之间，只有34%的参与者的自我报告和测量活动之间存在强烈的一致性（γ>= 0.7）。测量和自我报告的各种活动状态所用时间比例也显示出不一致（休息，r= 0.41;低水平活动，r= 0.39;中等水平，r= 0.26;高水平，r= 0.40）。有没有偏向于过度或低估reporting.Conclusions：大多数参与者无法准确地自我报告他们的活动水平（睡眠排除）相比，测量的活动水平。这可能对处方适当的假肢和为患者提供促进健康建议的临床医生具有重要意义。
Objective: To determine the accuracy of self-reported activity by community-dwelling, lower-limb amputees.Design: Descriptive study.Setting: A regional prosthetics outpatient service.Participants: Seventy-seven unilateral lower-limb amputees at least 6 months after prosthetic rehabilitation.Interventions: Not applicable.Main Outcome Measures: Measured activity counts (in steps/min) and self-reported activity (rest, low, medium, high) in 15-minute intervals over 1 week were recorded for each participant.Results: Participants averaged 3063 +/- 1893 steps per day. Strong agreement (gamma >= 0.7) between self-reported and measured activity was found for only 34% of participants between the hours of 9:00 AM to 9:00 Pm. The measured and self-reported proportion of time spent in various states of activity also showed poor agreement (rest, r=.41; low level activity, r=.39; medium level, r=.26; high level, r=.40). There was no bias toward either over- or under-reporting.Conclusions: The majority of participants were unable to accurately self-report their activity levels (sleep excluded) as compared with measured activity levels. This may have important implications for prescribing appropriate prosthetics and for clinicians who provide patients with advice on promoting health.
