Study Summary

This trial will evaluate the effectiveness of red light in stimulating blood flow changes in healthy adults.

Who is the study for?

This trial is for healthy adults aged 18-60, from any ethnic background. Participants must be able to understand and consent to the study in English. It's not suitable for those with heart or artery disease, high BMI, uncontrolled medical conditions, certain blood pressure levels, diabetes, kidney disease, neurological issues like stroke or cancer history.Check my eligibility

What is being tested?

The study tests how red light at a wavelength of 670 nm affects blood flow when applied to the leg. Additionally, participants will receive an infusion of Definity (octafluoropropane) contrast agent during the procedure.See study design

What are the potential side effects?

Potential side effects may include reactions to octafluoropropane such as shortness of breath or allergic responses. The red light treatment is generally considered safe but could cause localized skin changes.

1Treatment groups

Experimental Treatment

Group I: 670 nm lightExperimental Treatment2 Interventions

Subjects will have baseline blood flow measured in the gastrocnemius using octafluoropropane infusion and ultrasound.After baseline flow measurements are obtained, a 670 nm light emitting diode will be placed 1 cm above the gastrocnemius muscle. The diode will not be in direct contact with the skin. Subjects will be exposed to 75 mW/cm2. Contrast images will be obtained up to 5 minutes after the commencement of light.

Are new enrollees being accepted into this trial at present?

"Clinicaltrials.gov declares that this research project is searching for participants, with the initial posting being on November 1st 2014 and most recent update occurring at May 9th 2022."

Answered by AI

What criteria must an individual satisfy to qualify for this experiment?

"This clinical trial is searching for 40 individuals aged 18 to 59 that are exposed to man-made visible light. The study is open to all ethnicities and genders, making it an inclusive research effort."

Answered by AI

How many participants have been registered for this clinical trial?

"Yes, according to information on clinicaltrials.gov this research is presently recruiting patients; it was initially posted in November 2014 and has been amended as recently as May 2022. In total, 40 participants need to be sourced from a single medical site."

Answered by AI

What health conditions can be addressed with 670 nm light therapy?

"The therapeutic application of 670 nm light is best known for its use in echocardiography. However, this form on phototherapy can also help with cardiovascular diseases, diagnostic imaging, and left ventricular imaging."

Answered by AI

Are elderly individuals eligible for participation in this research endeavor?

"This trial has stipulated that participants must be between 18 and 59 years old to qualify for inclusion."

Answered by AI

What antecedent examinations have been undertaken that incorporate 670 nm light?

"Currently, 19 studies exploring 670 nm light are underway. Of those currently in operation, 1 study is already at Phase 3. Philadelphia Pennsylvania hosts the most clinical trials for this treatment but there are 26 sites across America running investigations into these phototherapy techniques."
