Peripheral Artery Disease study: Far red light therapy
Official title ENhancing Exercise With LIGHT to Improve Functioning in PAD
ClinicalTrials.gov ID: NCT06399900
What this study is testing
- What it's testing
- The study wants to find out whether shining a specific light on the legs before home walking exercises can improve how far participants can walk in six minutes after four months.
- Who it's for
- Adults who have peripheral artery disease that makes walking difficult.
- What's involved
- Participants will use a 660 nm light device on their lower legs each day before their usual home walking routine, and they will be compared to a group using a sham (inactive) light.
- Time commitment
- The trial lasts about four months, with regular visits to check progress and collect walking test results.
