Shining a light on leg pain: new trial tests simple home therapy for PAD

This study tests whether shining a specific red light on the legs each day before a walking session can help people with peripheral artery disease (PAD) walk farther. PAD causes leg pain and difficulty walking due to poor blood flow. The trial will involve 32 adults aged 50 and older with PAD, comparing real light treatment to a sham (fake) light over 4 months. The main goal is to see if the light improves walking distance and leg blood flow.
