About the study
The goal of this clinical trial is to assess the effects of passive calf muscle stretching in patients diagnosed with peripheral artery disease (PAD). The main question it aims to answer are:
1. To determine if daily calf muscle stretching at home improves calf muscle and vascular health. 2. To determine if daily calf muscle stretching at home improves walking performance.
Participants will use inflatable ankle splints for 30 minutes a day, 5 days a week for 4-weeks on both days and 4-weeks of no stretching.
