Agreement Between Activity Monitoring Devices During Home Rehabilitation: A Sub-Study of the AAA Stop Trial

Purpose To assess the association between activity monitoring devices for estimating energy expenditure (EE) in the context of a home-based rehabilitation program.

Methods Twenty four patients with abdominal aortic aneurysm (AAA) disease participating in a home-based rehabilitation program were studied. For 3 consecutive days (12 awake hours/day), subjects wore an accelerometer (ACC), a pedometer, and a heart rate monitor (HR), and recorded hourly activity logs. Subjects then completed a 3-day activity recall questionnaire (3-DR), which was used as the criterion. Standardized equations were used to estimate EE in kcals.

Results Total mean EE in kcals/day for HR, ACC, and 3-DR were 1674±464, 2068±529, and 1966±511, respectively. Differences in EE were not significant between 3-DR and ACC, but HR differed from both ACC.

Conclusions ACC provided an accurate reflection of EE based on the criterion measure, an activity recall questionnaire. ACC can be effectively used to monitor EE in order to achieve an appropriate training stimulus during home-based rehabilitation.
