Using light therapy to enhance exercise for better mobility in older adults with peripheral artery disease.

Official title: ENhancing exercise with LIGHT to improve functioning in PAD: the ENLIGHTEN PAD Trial

Funded at Northwestern University at Chicago · NIH-10851012 · Data updated 2026-11-12

This study is looking at whether using special red light therapy before walking exercises can help older adults with peripheral artery disease walk longer and feel better, making it easier for them to stay active at home.

Who could benefit from this research

Could help

Ideal candidates for this research are older adults diagnosed with peripheral artery disease who experience walking difficulties.

Less likely to help

Patients who do not have peripheral artery disease or those who are unable to participate in walking exercises may not benefit from this research.

What this research studies

This research investigates the use of 670 nm light therapy to improve the effectiveness of walking exercises for older adults suffering from peripheral artery disease (PAD). The study aims to determine if administering light therapy before exercise can help increase the duration and intensity of walking, thereby enhancing overall mobility and reducing symptoms. Participants will engage in home-based walking exercises, with some receiving light therapy to see if it improves their exercise adherence and outcomes. The approach focuses on leveraging the body's natural signaling mechanisms to improve blood flow and muscle function.

Why it matters

Potential benefit: If successful, this research could significantly improve mobility and quality of life for patients with peripheral artery disease.

How similar studies have gone: Previous studies have shown promising results with light therapy in enhancing exercise outcomes, suggesting potential for success in this approach.
