Telerehabilitation in Patients With Peripheral Arterial Disease

Grigore T. Popa University of Medicine and Pharmacy42 enrolled

Overview

This prospective longitudinal study evaluated the feasibility, adherence, and clinical and functional effects of a 6-month home-based telerehabilitation program in patients with peripheral arterial disease of the lower limbs. The program consisted of walking-based physical activity monitored using a smartwatch and weekly telephone counselling. Patients were encouraged to progressively increase their daily physical activity, with assessments performed at baseline, 3 months, and 6 months.

This prospective, single-arm study evaluated the feasibility and implementation of a 6-month home-based telerehabilitation program in patients with peripheral arterial disease (PAD) of the lower limbs. The intervention consisted of an individually prescribed walking-based physical activity program performed at home, supported by wearable activity monitoring and weekly telephone counselling. Participants used a Xiaomi Smart Band 8 to monitor daily step counts and were encouraged to progressively increase their physical activity according to individualized weekly targets. During the weekly telephone contacts, the investigator reviewed the participant's activity during the preceding 7 days, assessed adherence and provided individualized encouragement and guidance regarding continuation and progression of the walking program. Clinical, functional, laboratory, and health-related quality-of-life assessments were performed at baseline, 3 months, and 6 months. Functional evaluation included the 6-minute walk test, ankle-brachial index, and cardiopulmonary exercise testing. Laboratory assessments included selected cardiometabolic and inflammatory parameters. Disease-specific health-related quality of life was assessed using validated PAD-specific questionnaires. The study was designed to evaluate the feasibility and adherence to a digitally supported home-based rehabilitation model and to explore longitudinal changes in physical activity, functional capacity, quality of life, and selected clinical and laboratory parameters during the 6-month intervention period. As the study used a single-arm design without a control group, longitudinal changes were considered exploratory and cannot be interpreted as causal effects of the intervention.

Home-based telerehabilitationBEHAVIORAL

A 6-month home-based walking program supported by smartwatch-based monitoring of daily step counts and weekly telephone counselling. During weekly telephone contacts, the investigator reviewed the participant's activity during the preceding 7 days, assessed adherence, and provided individualized guidance and encouragement to continue and progressively increase walking activity.
