Trial Review

Please note the ANZCTR will be unattended from Friday 20 December 2024 for the holidays. The Registry will re-open on Tuesday 7 January 2025. Submissions and updates will not be processed during that time.

Study type
Interventional
Description of intervention(s) / exposure
Patients will undergo 12-week supervised treadmill walking training 3 times a week (group A) and 12-week supervised walking training with poles 3 times a week (group B).

Supervised walking training with poles will take place in a park. One session of walking with poles will last approximately 1 hour. GPS watches with compatible heart rate monitors will be used to track distance, time and pace of walking and monitor heart rate.

Supervised walking treadmill training will be conducted indoors according to TASC II guidelines (beginning with 30 minutes of training but then increasing to approximately 1 hour per session - extending 5 minutes every 2 weeks). All the interventions are administered on an individual basis according to the entry treadmill tests results. During the exercise session, treadmill exercise is performed at a speed and grade that will induce claudication within 3–5 minutes.
Patients should stop walking when claudication pain is considered moderate. (Moderate pain is a submaximal ischemic pain felt in lower extremity/extremities at level 4 on the 5-point pain intensity scale developed by the American College of Sports Medicine ACSM). Level 2 in the scale: Start of claudication may be described as pain, ache, cramping, a sense of fatigue, or nonspecific discomfort felt in lower extremity/extremities that occurs with exercise. The patient will then rest until claudication has abated, after which the patient should resume walking until moderate claudication discomfort recurs.
Target exercise intensity for each group: 65-75% maximal heart rate.
Physical therapist will be administering the intervention.
