Objective physical activity assessment in patients with chronic organ failure: a validation study of a new single-unit activity monitor.
OBJECTIVE
To validate a new activity monitor (CAM) in patients with chronic organ failure during 1 hour of unconstrained activity assessment.


METHODS
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.


METHODS
CIRO+, A Centre of Expertise for Chronic Organ Failure.


METHODS
Chronic organ failure patients (N=10) with a large range of functional exercise capacity.


METHODS
Not applicable.


METHODS
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.
