Supervised Exercise Therapy using Mobile Health Technology in Patients with Peripheral Arterial Disease: A Pilot Randomized Controlled Trial.
ABSTRACT
Background:
Mobile interventions are intended to digitally nurse complex health care needs in chronic diseases, but they are mainly targeted at general health improvement and neglect disease-specific requirements. Therefore, we designed TrackPAD, a smartphone app to support supervised exercise training (SET) in patients with peripheral arterial disease (PAD).
Objective:
The aim of the present pilot study was to evaluate suitability, feasibility, and the impact on a prognosis relevant outcome measure for patients with PAD, the 6-minutes walking test, by using TrackPAD.
Methods:
Twenty-nine participants with symptomatic PAD were randomized. The study group (n=19) received usual care with additional use of TrackPAD. The control group (n=20) only received usual care.
Results:
The study group improved their 6-minutes walking distance, while the control group decreased their mean distance after 3 months of follow-up (83±72.2 vs. -38.8±53.7 m; p<0.01). The PAD-related quality of life improved significantly in terms of ‘symptom perception’ and ‘limitations in physical functioning’. Users’ feed-back showed increased motivation and a changed attitude to perform SET, while raising the educational background.
Conclusions:
Besides the rating as a valued support tool by the user group, the mobile intervention TrackPAD was linked to an improvement in prognosis relevant outcome measure combined with an enhanced disease coping. Clinical Trial: International Registered Report Identifier (IRRID): DERR1-10.2196/13651
