Abstract

The aim of this study was to examine the quantitative relationship between physical activity and heart rate in dementia patients. Acceleration at the waist, wrist and ankle and ECGs were measured by an ambulatory monitor. At the same time as these measurements subject records were noted by a psychotherapist. Fourteen late stage dementia patients and fifteen normal elderly performed daily activity between 10 am and 4 pm. Changes in heart rate were associated with changes in acceleration in both groups, but intermittent activity changes were observed in dementia patients. The mean acceleration frequency and amplitude in the dementia group were significantly lower than those in normal elderly subjects. There was no correlation between the severity of intellectual deterioration and the degree of behavior disintegration in dementia patients. The elderly shifted smoothly between activities. The dementia patients showed sudden fluctuations of activity. The ambulatory monitor is an effective method for the quantitative assessment of dementia patients.

通过持续身体活动监测对痴呆患者行为进行定量评估

这项研究的目的是检验痴呆症患者体力活动和心率之间的定量关系。通过动态监护仪测量腰、腕、踝加速度和心电图。在进行这些测量的同时，心理治疗师会记录受试者的记录。14名晚期痴呆患者和15名正常老年人在上午10点到下午4点之间进行日常活动。在两组中，心率的变化与加速度的变化有关，但在痴呆患者中观察到间歇性的活动变化。痴呆组的平均加速度频率和振幅明显低于正常老年人。痴呆患者智力退化的严重程度与行为解体的程度无相关性。老人在各种活动之间转换自如。痴呆症患者表现出活动的突然波动。动态监测是对痴呆患者进行定量评估的有效方法。
