Effectiveness of pedometer-based exercise program in phase 1 and phase 2 cardiac rehabilitation: A Systematic Review

Background: Physical Inactivity (PI) and sedentary behaviour are the most important and modifiable risk factors to prevent cardiovascular diseases (CVD). Cardiac rehabilitation (CR) is a multidisciplinary program for patients who have undergone cardiac surgeries. Through CR, monitoring physical activity (PA) is possible and may reduce the rate of rehospitalization. The pedometer is a device that is useful to track the step count of the person day to day. It helps in self-monitoring of PA. The purpose of this review was to summarise the evidence about the effect of pedometer-based exercise program in phase 1 and phase 2 CR. Methods: Databases such as MEDLINE, Cochrane, Scopus, Embase, and Web of Science were searched. This search is limited to randomized controlled trials (RCTs), human trials, a 10-year period, and English language journals. Based on inclusion criteria of pedometer-based exercise programs in phase 1 (inpatient phase) and phase 2 (outpatient phase) of CR and exclusion criteria of studies using pedometer in maintenance phase CR. The primary outcome of the study is step count, while secondary is PA (in terms of time), heart rate, sedentary behaviour, and quality of life. This study quality was assessed by the Downs and Black’s checklist. Results: The study includes 6 RCTs based on the inclusion and exclusion criteria. Most studies show a considerable increase in step count associated with increased patient PA. Few studies have explained a significant increase of PA in the study group and maintained for longer terms. More research is needed to determine the impact of cardiovascular risk factors.
