开发了一种动态加速度监测器，用于评估老年人的身体活动。记录正常日常活动的在职和退休老年妇女的心电图和腕、腰、踝关节的加速度，并评估单位时间内的心率和加速度频率和振幅。心率与手腕加速度密切平行。被试的行为模式可以通过时间间隔信号和直方图分布来区分。这一系统似乎是一种定量和客观地理解和描述老年人特征活动的有效方法。
An ambulatory acceleration monitor was developed and used to evaluate physical activity in the elderly. The ECG and accelerations at the wrist, waist, and ankle were recorded, and the heart rate and frequency and amplitude of accelerations per unit time were evaluated in both working and retired elderly women performing normal daily activities. The heart rate closely paralleled wrist acceleration. The behaviour patterns of the subjects could be differentiated by time interval signals and histogram distributions. This system appears to be an effective method of understanding and describing the characteristic activities of the elderly in a quantitative and objective fashion.
