需要有效和可靠的游荡措施来研究这种令人不安的行为。虽然研究者们使用了不同的视角、定义和方法来研究流浪，但自发性流浪是所有观点的一个关键特征。用于捕获运动的生物力学活动装置提供了一种索引游走的方法。本研究检查了四个设备与门诊养老院居民痴呆症（N = 178），同时佩戴设备在四个观察。在Actillume、StepWatch、Step Sensor和TriTrac-R3D中，StepWatch产生的数据来自最高比例的观察结果，解释了所有仪器中最大的方差（63.9%），并且被护理人员接受。虽然步传感器是工作人员的首选设备，其性能是最不可接受的研究目的。结果支持使用StepWatch在未来的研究流浪。
Valid and reliable measures of wandering are needed to study this troubling behavior. Although researchers have used various perspectives, definitions, and approaches to study wandering, spontaneous ambulation is a key characteristic across all views. Biomechanical activity devices for capturing movement provide one way to index wandering. This study examined four devices with ambulatory nursing home residents with dementia (N = 178) who wore devices simultaneously during four observations. Among the Actillume, StepWatch, Step Sensor, and TriTrac-R3D, the StepWatch yielded data from the highest proportion of observations, explained the most variance (63.9 percent) among all instruments, and was acceptable to nursing staff. Although the Step Sensor was the staff's preferred device, its performance was least acceptable for research purposes. Results support use of the StepWatch in future studies of wandering.
