Subjects will have a mechanically induced bruise photographed over a period of 11 days to record the healing process. Assessors will rate the bruises to develop a bruising scale.

Observational study. Healthy normal volunteers will come into the clinic and have a bruise induced. The bruised area will be photographed each day through Day 11. Images will be provided to the Validator Team to rate on a 0-5 scale of severity.

The actual numbers of volunteers will be adjusted to ensure there are at least 15 images for each Grade.

The clinical site will be provided photography equipment, and study staff will be trained on photography technique to standardize the image quality and resolution across the study.

The Validator Team will review the images and categorize them in to Grades 0-5.
