Summary

This trial will investigate if calf stretching can improve calf muscle and vascular health, as well as walking performance, in patients with PAD.

Who is the study for?
This trial is for men and women aged 40-85 with stable peripheral artery disease (PAD) symptoms for at least three months. They must not be pregnant, nursing, or have had major surgeries recently. Excluded are those with uncontrolled diabetes, recent heart issues, habitual exercisers, ankle injuries within a year, severe lung disease, current smokers or nicotine users.
What is being tested?
The study tests if using an inflatable calf muscle stretching device at home can improve muscle and vascular health as well as walking performance in PAD patients. Participants will stretch daily for 30 minutes over four weeks followed by four weeks without stretching.
What are the potential side effects?
Potential side effects may include discomfort or pain from stretching the calf muscles too much. There might also be risks of worsening PAD symptoms due to increased activity levels during the intervention.

Trial Design

2Treatment groups
Experimental Treatment
Active Control
Group I: 4-weeks of passive calf stretching for 30 minutes 5 days a weekExperimental Treatment1 Intervention
A modified plantar fasciitis ankle splint will be used to passively stretch the calf muscle.
Group II: 4-weeks of no-stretchingActive Control1 Intervention
No device will be used to stretch the calf muscle. Participants will go about their normal daily activity for 4-weeks.
