Led By Mohab Ibrahim, PhD, MD.

Research Sponsored by University of Arizona

Eligibility Criteria Checklist

Specific guidelines that determine who can or cannot participate in a clinical trial

Must have

No history of Chronic pain

18-50 years healthy men or women

Must not have

Tissue damage in areas that testing will take place (forearms, muscle at the base of the thumb on the palm of the hand, and upper back/should area)

Timeline

Screening 3 weeks

Treatment Varies

Follow Up two hours

Summary

This trial will study how green light exposure affects different types of pain in humans to better understand the mechanisms of action for this natural pain relief method.

Who is the study for?

This trial is for English-speaking men and women aged 18-50 who are generally healthy, without chronic pain or neuropathies in certain body areas. It's not suitable for those with colorblindness, uncorrected cataracts, serious mental illness, or tissue damage where testing will occur.

What is being tested?

The study aims to understand how green light exposure can relieve pain by comparing the effects of green and white light-emitting diodes (LEDs) on participants. The mechanisms behind the pain-relieving properties observed in previous studies are being investigated.

What are the potential side effects?

Since this trial involves exposure to LED lights rather than drugs or invasive procedures, side effects may be minimal but could include eye strain or headache from prolonged exposure to bright lights.

Placebo Group

Group I: Green Light ExposureActive Control1 Intervention

Subjects will complete thermal and mechanical pain threshold detection tests and Electroencephalography (EEG). After completion, subjects will be exposed to a green light-emitting diode for two hours. After exposure, thermal and mechanical pain threshold assessments and Electroencephalography (EEG) will be conducted.

Group II: White Light ExposurePlacebo Group1 Intervention

Subjects will complete thermal and mechanical pain threshold detection tests and Electroencephalography (EEG). After completion, subjects will be exposed to a white light-emitting diode for two hours. After exposure, thermal and mechanical pain threshold assessments and Electroencephalography (EEG) will be conducted.
