Blood flow in small vessels during passive heating

This trial tests whether a gentle electrical stimulation (TENS) applied to the leg muscles and nerve clusters can improve blood flow behind the knee. It looks at immediate effects and might help understand better ways to support circulation.

This trial studies whether applying heat to your legs can improve symptoms and function in people with peripheral artery disease (reduced blood flow to the legs). You may be tested with a simple blood-flow check and an MRI scan, depending on eligibility.

This study tests whether heat therapy (like warm baths or heat packs) can improve blood flow and walking ability in people with peripheral artery disease (PAD). If you have leg pain when walking due to PAD, this treatment might help you walk further with less discomfort.

This study tests whether using passive heat (warming therapy, not exercise) can improve breathing and body comfort in people with COPD who are not currently flaring up. It may help by seeing if heat changes how well you tolerate breathing and physical activity during testing.

This study tests whether regularly using passive heat can lower your systolic blood pressure (the top number) and improve how your blood vessels work. If you’re eligible, you may be randomly assigned to try the heat therapy as a 6-month program.

This study tests if shining a specific type of light on your skin can improve blood flow in tiny blood vessels. You'll come in for two sessions where we apply different light wavelengths and measure your skin’s response.
