通过定期但不频繁的办公室访问对患者进行持续或治疗后监测的现有范例具有许多局限性。依靠患者或其家属的自我报告同样不可靠。我们提出了一种替代范式，其中连续的，不显眼的监测是用来观察随着时间的推移在身体行为的变化。我们强调使用这种技术来监测运动活动，这可能是老年人早期认知变化的预测。使用低成本的无线传感器系统的初步结果，连同适当的分析和解释这些数据的讨论。使用低成本的无线传感器网络加上算法来检测相关行为模式的变化，我们能够检测到可能需要医疗干预的急性和渐进的变化。
The existing paradigm of ongoing or posttreatment monitoring of patients through periodic but infrequent office visits has many limitations. Relying on self-report by the patient or their family is equally unreliable. We propose an alternative paradigm in which continuous, unobtrusive monitoring is used to observe changes in physical behavior over time. We highlight the use of this technique for monitoring motor activity that may be predictive of early cognitive changes in the elderly. Initial results using a system of low-cost wireless sensors are presented, together with a discussion of appropriate analyses and interpretation of such data. Using low-cost wireless sensor network coupled with algorithms to detect changes in relevant patterns of behavior, we are able to detect both acute and gradual changes that may indicate a need for medical intervention.
