U.S., Feb. 6 -- ClinicalTrials.gov registry received information related to the study (NCT06809569) titled 'A Study to Evaluate Laser Speckle Contrast Imaging to Assess Changes in Chemical Agent-Induced Skin Blood Flow in Healthy Participants (MK-0000-420)' on Jan. 30.

Brief Summary: Pain is a significant issue and there is a need for better treatments for pain management. Local changes in skin blood flow can be used as an indicator of pain in the body. Capsaicin and allyl isothiocyanate (AITC) increase blood flow and cause pain. The purpose of this study is to evaluate the use of laser speckle contrast imaging (LSCI) as a tool to assess changes in skin blood flow. Researchers want to learn about the effect size and reproducibility of usin...
