Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Patients will participate in 12-week supervised treadmill training 3 times a week. During each exercise session, treadmill walking is performed at a speed 2 mph and individually matched grade that will induce moderate claudication within 3–5 minutes. The initial grade is based on the entry treadmill tests results. 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, where 1 = no pain, 2 = onset of claudication, 3 = mild pain, 4 = moderate pain, and 5 = maximal pain). Therefore, the patient starts walking with no pain and after the onset of claudication pain walking is continued until the pain is considered moderate.
After exercise, the patient is resting in sitting position until claudication is lessened and then treadmill walking is resumed. Each session of intermittent treadmill walking exercise will be applied for 35 minutes at the start of the program with progressive increase of session time by 5 minutes per 2 weeks. On following sessions the grade of the treadmill will increase when patient is able to walk for 8 minutes or longer on previous workload. Warm up and cool down are not planned.
Physical therapist will administrate the intervention. It will be one-on-one face-to-face exercise session. There will be an attendance list to monitor patients adherence to intervention. Also, each walking time on each session will be noted.
