title: Agreement between activity-monitoring devices during home rehabilitation: a substudy of the AAA STOP trial.
abstract: As part of a home-based rehabilitation program, 24 older adult patients (71 ± 3 years) with abdominal aortic aneurysm (AAA) disease underwent 3 days (12 awake hr/day) of activity monitoring using an accelerometer (ACC), a pedometer, and a heart rate (HR) monitor, and recorded hourly activity logs. Subjects then underwent an interview to complete a 3-day activity recall questionnaire (3-DR). Mean energy expenditure (EE) in kcals/ day for HR, ACC, and 3-DR were 1,687 ± 458, 2,068 ± 529, and 1,974 ± 491, respectively. Differences in EE were not significant between 3-DR and ACC, but HR differed from both ACC (p < .001) and 3-DR (p < .01). ACC and 3-DR had the highest agreement, with a coefficient of variation of 7.9% and r = .86. Thus, ACC provided a reasonably accurate reflection of EE based the criterion measure, an activity recall questionnaire. ACC can be effectively used to monitor EE to achieve an appropriate training stimulus during home-based cardiac rehabilitation.
