High Intensity Interval Training In pATiEnts With Intermittent Claudication — INITIATE  

Peripheral Arterial Disease Clinical Trial

Official title:
High Intensity Interval Training In pATiEnts With Intermittent Claudication (INITIATE): a Proof-of-concept Prospective Cohort Study to Assess Acceptability, Feasibility and Potential Clinical Efficacy

Clinical Trial Summary

This INITIATE study evaluates the use of high-intensity interval training as a treatment modality for patients with intermittent claudication - an ambulatory leg pain caused by narrowed arteries that supply the lower limbs. It is an observational cohort study considering HIIT as a treatment for intermittent claudication, consisting of two workstreams. Workstream 1: an initial observational cohort study to consider the feasibility of the intervention and exclusion criteria. Workstream 2: a proof of concept study utilising the altered intervention and exclusion criteria following recommendations highlighted during workstream 1.

Clinical Trial Description

Patients with peripheral vascular disease (PVD) may develop a reproducible pain in their legs when they walk, which usually subsides with rest. This is known as intermittent claudication (IC) and is caused by a reduced blood supply to the legs as a result of narrowed or hardened arteries that supply the lower limbs. This ambulatory pain impedes on activities of daily living, functional capacity and quality of life. NICE clinical guidance recommends a 12-week supervised exercise programme as first-line treatment for IC, whereby patients are encouraged to walk to the point of maximal pain. Robust clinical trials have demonstrated that supervised exercise programmes are efficacious for improving both pain-free and maximal walking distances, whilst also potentially improving quality of life. Despite this, supervised exercise programmes are vastly under-utilised and not always available to consultant vascular surgeons. This means that further programmes need to be developed in order to provide a range of options to patients to improve uptake and adherence rates. One such programme is a 6-week high-intensity interval training programme. An initial observational cohort study of the 6 week HIIT programme will be conducted to determine to determine the feasibility of the intervention and inclusion criteria. The results from this will be used to make any necessary changes to the HIIT intervention before moving into a proof of concept study, considering the utility, safety, acceptability and potential clinical efficacy of this programme. ;
