Abstract
Background and purpose: To validate an activity monitor, the Patient Resident Mobility Tracker (PREEMPT), appropriate for use with hospitalized individuals.
Methods and main outcome measures: Ten healthy older adults and 46 hospitalized patients wore the PREEMPT activity monitor while performing various physical activities. To determine accuracy and validity, the PREEMPT activity data were compared with video truth data. The five mobility metrics included stride length, number of steps, stepping time (total time spent walking), sedentary time and activity time. In addition to the objective data, participants answered 8 Likert scale usability questions about their experience wearing the PREEMPT device.
Results: The measurements taken by the PREEMPT device were statistically equivalent to criterion data for all five metrics with a geometric mean ratio ranging from 0.97 to 0.99. Statistical significance values (p) ranged from 0.043 to < 0.001 depending on the metric. The device received an average total score of 9.4 out of 10 on the Likert scale usability questions, indicating that the prototypical device was comfortable to wear and well received.
Discussion: These results demonstrate the initial validity and accuracy for the prototype PREEMPT device in healthy community-dwelling older adults as well as in hospitalized patients. The prototype PREEMPT device accurately measured physical activity in a relatively immobile population residing within a hospital setting.
Reporting method: This paper adheres to STROBE guidelines.
Trial registration: This research was not a clinical trial and did not require registration.
期刊介绍：
Physiotherapy Research International is an international peer reviewed journal dedicated to the exchange of knowledge that is directly relevant to specialist areas of physiotherapy theory, practice, and research. Our aim is to promote a high level of scholarship and build on the current evidence base to inform the advancement of the physiotherapy profession. We publish original research on a wide range of topics e.g. Primary research testing new physiotherapy treatments; methodological research; measurement and outcome research and qualitative research of interest to researchers, clinicians and educators. Further, we aim to publish high quality papers that represent the range of cultures and settings where physiotherapy services are delivered. We attract a wide readership from physiotherapists and others working in diverse clinical and academic settings. We aim to promote an international debate amongst the profession about current best evidence based practice. Papers are directed primarily towards the physiotherapy profession, but can be relevant to a wide range of professional groups. The growth of interdisciplinary research is also key to our aims and scope, and we encourage relevant submissions from other professional groups. The journal actively encourages submissions which utilise a breadth of different methodologies and research designs to facilitate addressing key questions related to the physiotherapy practice. PRI seeks to encourage good quality topical debates on a range of relevant issues and promote critical reflection on decision making and implementation of physiotherapy interventions.
