Systematic review of tracking-based technology for patients with claudication.

Introduction: Peripheral artery disease (PAD) typically presents with claudication. Although supervised exercise therapy is recommended, many hospitals do not have a program and therefore patients are unable to receive optimal therapy. Tracking-based technology (TBT), including activity monitors and mhealth applications, have stimulated the expansion into PAD management. This systematic review evaluates the effectiveness of TBT for claudication based on walking performance, perceived walking impairment, and quality of life (QoL).

Methods: A multidatabase search was undertaken using the terms PAD OR intermittent claudication AND wearable devices OR mobile health applications. This systematic review was conducted according to PRISMA guidelines.ResultsA literature search identified 586 studies, of which 18 were eligible for inclusion. This totaled 1055 patients, with 15 randomized controlled trials and three cohort studies. Patients in the TBT group showed improvements in all walking ability parameters (including 6-minute walking distance, claudication onset time, maximum walking time, maximum walking distance, and claudication distance), QoL, and in the self-reported walking impairment questionnaires.

Conclusion: There is evidence for supporting the introduction of TBT into the management of PAD as TBT improves walking performance, functional status, and QoL in patients with PAD. However, further information regarding adherence and compliance rates, as well as long-term outcomes, are imperative in assessing the effectiveness of TBT due to limited existing studies.
