A self-monitoring approach during cardiac rehabilitation significantly improves exercise maintenance, self-efficacy, and objective physical activity levels in post-myocardial infarction patients.

Self-monitoring should be integrated into post-MI cardiac rehabilitation; extends self-efficacy theory with RCT evidence on objective activity.
OBJECTIVE: To evaluate the effect of the self-monitoring approach (SMA) on self-efficacy for physical activity (SEPA), exercise maintenance, and objective physical activity level over a 6-mo period after a supervised 6-mo cardiac rehabilitation (CR) program. DESIGN: We conducted a randomized, controlled trial with 45 myocardial infarction patients (38 men, seven women; mean age, 64.2 yrs) recruited after completion of an acute-phase, exercise-based CR program. Patients were randomly assigned to an SMA group (n = 24) or control group (n = 21). Along with CR, the subjects in the SMA group self-monitored their weight and physical activity for 6 mos. The SMA used in this study was based on Bandura's self-efficacy theory and was designed to enhance confidence for exercise maintenance. The control group participated in CR only. All patients were evaluated with the SEPA assessment tool. Exercise maintenance, SEPA scores, and objective physical activity (average steps per week) as a caloric expenditure were assessed at baseline and during a 6-mo period after the supervised CR program. RESULTS: Mean period from myocardial infarction onset did not differ significantly between the SMA and control groups (12.1 +/- 1.3 vs. 12.2 +/- 1.2 mos, P = 0.692). All patients maintained their exercise routine in the SMA group. Mean SEPA score (90.5 vs. 72.7 points, P < 0.001) and mean objective physical activity (10,458.7 vs. 6922.5 steps/wk, P < 0.001) at 12 mos after myocardial infarction onset were significantly higher in the SMA than control group. SEPA showed significant positive correlation with objective physical activity (r = 0.642, P < 0.001). CONCLUSIONS: SMA during supervised CR may effectively increase exercise maintenance, SEPA, and objective physical activity at 12 mos after myocardial infarction onset.

Izawa et al. (2005) conducted an RCT in Myocardial infarction (n=45). Self-monitoring approach (SMA) vs. Cardiac rehabilitation only was evaluated on Mean self-efficacy for physical activity (SEPA) score (p=<0.001). A self-monitoring approach during cardiac rehabilitation significantly increased mean self-efficacy for physical activity scores (90.5 vs. 72.7 points, P<0.001) and objective physical activity.
