History of Changes

Purpose

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).

experimental rehabilitation program 20 patients are expected in this arm. Patients perform walking treadmill exercises with active recovery (no stop walking).

Procedure: experimental rehabilitation program

Duration training = 40 min : 5 cycles of 6 min each Week 1 speed of the walking exercise fixed at 70% of the max walking test's speed done on the initial walking test speed of the walking recovery fixed at 40% Walking slope : 0% Increase of the speed = 0.1 km/h after each training without pain.

Week 2 Walking speed = average of the walking speeds done on week 1 Walking slope = 1% Recovery slope = 0% Increase of the slope = 0.5% after each training without pain.
Week 3 Walking speed = 70% of the maximal walking test's speed Recovery speed = 40 % of the maximal walking test's speed Slope = average of the slopes done on week 2 Increase of the speed = 0.1 km/h .
Week 4 Speeds = average of the walking speeds done on week 3 Walking slope = 1% Recovery slope = 0% Increase of the slope is 0.5% .

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.
