Objective: To validate a new activity monitor (CAM) in patients with chronic organ failure during 1 hour of unconstrained activity assessment.
Design: A validation study in which participants wore a CAM (placed on the thigh) for 1 hour while they were videotaped. Participants were instructed to continue their normal daily routine at the rehabilitation center.
Setting: CIRO+, A Centre of Expertise for Chronic Organ Failure.
Participants: Chronic organ failure patients (N=10) with a large range of functional exercise capacity.
Interventions: Not applicable.
Main outcome measure: Agreement in time spent on activities and postures according to video and CAM.
Results: Cohen kappa coefficients for transient events resulted in an almost perfect agreement (0.85 ± 0.08) between the CAM and video.
Conclusions: The CAM is a promising single-sensor unobtrusive tool for providing accurate data on the type and duration of daily activities in the home environment of patients with chronic organ failure.
