背景：手术后早期活动可降低多种并发症的发生率。可穿戴运动传感器测量一段时间内的运动情况并无线传输这些数据，这有可能监测患者的康复情况并鼓励患者进行自己的康复。目的：我们试图确定现成的活动传感器远程监测患者术后活动能力的能力。方法：哥伦比亚大学神经外科连续招募受试者。患者在物理治疗期间被纳入。将两位盲人研究人员计算的总步数与位于不同身体位置的四个活动传感器记录的步数进行比较。结果：总共生成了 148 个运动数据点。设备准确记录每次步行的开始时间、结束时间和持续时间，并可远程供研究人员分析。放置在脚踝上的传感器精度明显高于放置在臀部上的传感器精度（P
Background: Early mobilization after surgery reduces the incidence of a wide range of complications. Wearable motion sensors measure movements over time and transmit this data wirelessly, which has the potential to monitor patient recovery and encourages patients to engage in their own rehabilitation.Objective: We sought to determine the ability of off-the-shelf activity sensors to remotely monitor patient postoperative mobility.Methods: Consecutive subjects were recruited under the Department of Neurosurgery at Columbia University. Patients were enrolled during physical therapy sessions. The total number of steps counted by the two blinded researchers was compared to the steps recorded on four activity sensors positioned at different body locations.Results: A total of 148 motion data points were generated. The start time, end time, and duration of each walking session were accurately recorded by the devices and were remotely available for the researchers to analyze. The sensor accuracy was significantly greater when placed over the ankles than over the hips (P
