ReviewThe的目的本文的目的是提供一个审查最近的工作上使用的可穿戴设备测量身体活动（PA）在elderly.Recent FindingsIn老年人，PA与独立的日常生活活动和保持良好的生活质量。随着年龄的增长，PA减少，这可以解释休息和PA期间能量消耗（EE）减少。此外，流动的空间范围（生活空间）也有所减少。用于测量PA的传感器包括步数计、单轴、双轴和三轴加速度计、结合加速度计的心率监测器以及使用多种类型传感器的复杂系统。总结可穿戴传感器在测量步数、PA强度和EE方面是准确的，但需要提高测量PA类型、PA空间范围和测量非走动PA的准确性。需要制定明确的测量标准，用于计算临床相关措施的算法。
Purpose of ReviewThe goal of this paper is to provide a review of recent work on the use of wearable devices for measuring physical activity (PA) in the elderly.Recent FindingsIn older adults, PA is related to independence in activities of daily living and maintaining a good quality of life. With aging, there is a reduction in PA, which may explain reduced energy expenditure (EE) during rest and PA. In addition, there is also a reduction in the spatial extent of mobility (life-space). Sensors used for measuring PA include pedometers, uni-axial, bi-axial and tri-axial accelerometers, heart rate monitors combined with accelerometers, and complex systems using multiple types of sensors.SummaryWearable sensors are accurate at measuring step counts, PA intensity, and EE, but need to improve accuracy of measuring type of PA, spatial extent of PA, and measuring non-ambulatory PA. Clear standards for measurement, algorithms used for computing clinically relevant measures, need to be developed.
