A Novel App for Assessing the Caregivers' Physical Activity: A Pilot/Feasibility Study

This study sought to determine the feasibility and clinical value of using a novel mobile application (app) to record the muscle/physical activity (PA) of caregivers. In all, 23 caregivers were enrolled and they were trained to use the app and a wearable device that automatically recorded their care activities and PA/burden. Data were collected for 42 days. Muscle activity was measured for 3 weeks during maximum voluntary isometric contraction (MVIC) and PA. Approximately 80% of the caregivers agreed that they conveniently used the wearable device through the mobile app. The most active %MVIC was noted for the back muscles during feeding assistance. As regard subjective pain evaluation, back pain was the most prevalent and pain level in the left knee was the highest. Incorporating mobile apps with wearable devices to record every activity of the caregivers may be feasible and can provide valuable clinical data for optimizing their pain management.
