Digital Support for Supervised Exercise Therapy in Peripheral Arterial Disease (TrackPAD)
Supervised Exercise Therapy Using Mobile Health Technology in Patients With Peripheral Arterial Disease: Randomized Controlled Pilot Trial.
The individual restrictions of daily life for patients with PAD are more important than statistical facts for mortality and morbidity. Intermittent claudication causes a progressive reduction of the pain-free walking distance (PWD) as an expression of a worsening PAD. This decrease in physical capability results in a decline of mental health and relevantly reduces the patients' quality of life (QoL).
Supervised exercise therapy (SET) is a cornerstone in the conservative management of intermittent claudication and extends the PWD. Even though SET is easy to practice and highly cost effective, the adherence to perform SET on a regular base is rather low. The underuse of exercise can be partly explained by the lack of institutional resources, but also by both patients' and physicians' lack of interest in exercise.
Mobile health (mHealth) technologies increase the incentives and provide digital support for patients with PAD on several treatment levels. They might lead to a higher adherence to exercise training and offer new scopes in patient-centered healthcare, but so far studies show opposite results. Because app stores are flooded with health and fitness apps, specific support tools are highly desired by patients with PAD and PAD-specific solutions are missing so far. Based on this background, the investigators developed a smartphone app named TrackPAD to provide PAD-specific support for SET.
The TrackPAD pilot study was designed as a 2-armed randomized controlled trial and included patients with diagnosed and symptomatic PAD. Patients were randomized by the Center for Clinical Studies in Essen using the TENALEA software into 2 groups. The control group included participants with standard care and no further mobile intervention. The intervention group included participants with standard care and additional mHealth-based self-tracking of their physical activity using trackPAD.

|
peripheral arterial disease-related quality of life
Periodo de tiempo: baseline, 3 months follow-up
|
measured with the Peripheral artery disease Quality of Life Questionnaire (PADQOL) questionnaire, a validated PAD-specific questionnaire.
Minimum score is 38 and maximum is 228, with higher values indicating a better outcome.
|
baseline, 3 months follow-up
|
|
Usability of the TrackPAD app
Periodo de tiempo: baseline, 3 months follow-up
|
measured with the User version of the Mobile Application Rating Scale (uMars) questionnaire.
The uMARS includes 3 factors, namely app quality, app subjective quality and perceived impact.
Minimum score of the app quality scale is 4 and the maximum is 20.
The App Subjective Quality scale has a minimum of 4 and a maximum of 20, and the Perceived Impact scale has a minimum of 6 and a maximum of 30.
Higher values indicate a better outcome.
