K. Determination of the effectiveness of accelerometer use in the promotion of physical
activity in cardiac patients: a randomized controlled trial.
Objective
To investigate the effect of the self-monitoring of physical activity by hospitalized
cardiac patients attending phase I cardiac rehabilitation (CR).
Design
Randomized controlled trial.
Setting
University hospital CR program.
Participants
CR patients (N=126) with a mean age of 59.1 years.
Interventions
Patients were randomly assigned to the self-monitoring group (group A, n=63) or the
control group (group B, n=63). Along with CR, group A patients performed self-monitoring
of their physical activity at the beginning of a phase I CR program (acute in-hospital
phase for inpatients) and ending just before they began a phase II CR program (postdischarge
recovery phase for outpatients).
Main Outcome Measures
Physical activity (averages of daily number of steps taken and daily energy expenditure
for 1wk) as measured by accelerometer was assessed in both groups at baseline (t1)
and before the beginning of phase II CR (t2).
Results
Although there were no significant differences in physical activity values between
groups A and B at t1, values of group A at t2 were significantly higher than those
of group B (8609.6 vs 5512.9 steps, P<.001; 242.6 vs 155.9kcal, P<.001).
Conclusions
Self-monitoring of patient physical activity from phase I CR might effectively increase
the physical activity level in preparation for entering a phase II CR program. Results
of the present study could contribute to the development of new strategies for the
promotion of physical activity in cardiac patients.
