Intensive Rehabilitation in Peripheral Arterial Disease With Claudication: Effects of a Treadmill Training With Active Recovery

Phase 3
Completed
Conditions
Peripheral Arterial Disease
Claudication
Registration Number
NCT01734603
Lead Sponsor
University Hospital, Grenoble
Brief Summary

Rehabilitation is the first intention treatment of peripheral arterial disease (PAD) with claudication. Initially proposed in the sixty's, rehabilitation programs dedicated to patients with PAD have recently been proved effective and defined in many guidelines. Supervised walking training on treadmill is recommended. Usually patients walk up to a mild or moderate pain (evaluated at 3 or 4 on the claudication pain scale; maximum pain =5), then stop until pain completely subsides and walk again .

The Artex study assesses the efficacy of a fractionated mode of training avoiding pain by alternating short sequences of intensive training and active recovery (without rest).

Detailed Description

Fractionated mode of training with active recovery has been proved effective in sport training as well as in Cardiac rehabilitation. We hypothesized it might be also interesting in the rehabilitation of patients with a peripheral arterial disease. The active recovery period might magnified the beneficial effect of a short intensive training.

PARALLEL
Primary Outcome Measures
NameTimeMethod
Intensive Rehabilitation in Peripheral Arterial Disease with Claudication: effects of a treadmill training with active recoveryBetween day 0 and day 28

Change in walking distance between day 0 and day 28, measured on a graded treadmill test

Secondary Outcome Measures
NameTimeMethod
Determine vascular and respiratory parameters which participate to improve the walking abilities after rehabilitation.Between day 0 and day 28

* Measure of ABI(Ankle-to- Brachial systolic blood pressure Index) and recovery time

* Measure of the transcutaneous oxygen pression

* Measure of the maximal cardiac frequency

* Measure of peak oxygen consumption and lactatemy

One year follow-upone year

All patients included are invited to be assessed at a one year. Interview, Clinical Examination, and Assessemnts are performed in day hospital (half a day).

Criteria are:

Patients 'satisfaction about protocole using an ad hoc ordinal scale Medical and duplex scan examinations Vascular risk factors and comorbidities Occurence of any medical event during the year Changes in WIQ and HADS changes in walking distance at the Graduated Treadmill Test.

Reproducibility test of the walking graduated treadmillDay 0 et day 1

The fifteen last patients are invited to perform the consecutive graduated treadmill test on day 0 et day 1. Reproducibility of the walking distance assess by this novel test is quantified.
