中风和其他神经系统疾病后转诊到康复服务的一个关键原因是改善一个人在日常生活中的功能。衡量一个人在日常生活中的活动变得非常重要，而不仅仅是衡量他们在诊所或实验室的结构化环境中的活动能力。现在能够测量日常运动的可穿戴传感器是加速度计。加速度计是一种商用设备，类似于大型手表，可以全天佩戴。来自加速度计的数据可以量化肢体如何参与人们的家庭和社区活动。本报告描述了一种方法来收集加速度计数据，并将其转化为临床相关的信息。首先，通过让参与者佩戴两个加速度计（每个手腕上一个）24小时或更长时间来收集数据。然后下载并处理加速度测量数据，以产生描述日常生活中上肢活动的关键方面的四个不同变量：使用小时数、使用比率、幅度比率和双侧幅度。可以构建密度图，直观地表示24小时佩戴期的数据。这些变量及其产生的密度图在神经系统完整的社区居住成年人中高度一致。这种惊人的一致性使它们成为确定上肢日常表现是否与正常不同的有用工具。该方法适用于调查上肢功能障碍的研究和旨在改善卒中患者和其他患者人群日常生活中上肢表现的干预措施。由于其相对简单，它可能不会很久之前，它也被纳入临床神经康复实践。
A key reason for referral to rehabilitation services after stroke and other neurological conditions is to improve one's ability to function in daily life. It has become important to measure a person's activities in daily life, and not just measure their capacity for activity in the structured environment of a clinic or laboratory. A wearable sensor that is now enabling measurement of daily movement is the accelerometer. Accelerometers are commercially-available devices resembling large wrist watches that can be worn throughout the day. Data from accelerometers can quantify how the limbs are engaged to perform activities in peoples' homes and communities. This report describes a methodology to collect accelerometry data and turn it into clinically-relevant information. First, data are collected by having the participant wear two accelerometers (one on each wrist) for 24 h or longer. The accelerometry data are then downloaded and processed to produce four different variables that describe key aspects of upper limb activity in daily life: hours of use, use ratio, magnitude ratio, and the bilateral magnitude. Density plots can be constructed that visually represent the data from the 24 h wearing period. The variables and their resultant density plots are highly consistent in neurologically-intact, community-dwelling adults. This striking consistency makes them a useful tool for determining if upper limb daily performance is different from normal. This methodology is appropriate for research studies investigating upper limb dysfunction and interventions designed to improve upper limb performance in daily life in people with stroke and other patient populations. Because of its relative simplicity, it may not be long before it is also incorporated in clinical neurorehabilitation practice.
