Wearable technology in rehabilitation: assessing the impact of the Apple watch on physical activity and cardiovascular health: a scoping review.

Abstract

Introduction: The Apple Watch is increasingly used in rehabilitation to monitor physical activity, cardiovascular health, and other physiological parameters. This review evaluates its effectiveness and accuracy in various rehabilitation settings, examining its potential to enhance patient adherence and clinical outcomes.

Evidence acquisition: A comprehensive search was conducted across databases including MEDLINE, Cochrane Central, Scopus, PEDro, and Web of Science, alongside grey literature. Studies were included based on the PCC criteria (Population, Concept, Context), focusing on the use of the Apple Watch in rehabilitation programs. Bias risk was assessed using RoB 2 for RCTs and ROBINS-I for non-randomized studies.

Evidence synthesis: Five studies were reviewed. The Apple Watch showed potential in improving physical activity levels and functional outcomes, particularly when combined with behavioral interventions. It demonstrated effectiveness in detecting atrial fibrillation in large-scale screening but presented variability in heart rate and energy expenditure accuracy, especially during high-intensity activities. The studies highlighted that integrating cognitive support with the device enhances adherence and health outcomes. However, limitations in measurement accuracy and the need for hybrid monitoring approaches were noted.

Conclusions: The Apple Watch is a valuable tool in rehabilitation when used alongside behavioral support and validated clinical methods. Its effectiveness is enhanced when integrated into a multidisciplinary approach, but its limitations in accuracy necessitate further calibration and hybrid use with traditional tools. Future research should focus on long-term impacts and algorithm improvements to optimize its clinical utility in diverse rehabilitation contexts.
