This project is for the development and validation of a rigid-body spring model of the entire forearm.  Because the two bones of the forearm have multiple joints with each other and with the wrist bones and the humerus at the elbow, the only way to fully  understand the mechanics of the wrist or the elbow is to fully account for both in experimental studies and computational models.  This short-term project is to collect data to reinforce and application for funding from the National Science Foundation.

This project uses existing medical records and biomechanical experiments to determine the causes of increased ulnar variance with age and the ulnocarpal impaction syndrome which generally accompanies it.  The study also considers the difference between symptomatic and asympotmatic people with positive ulnar variance.  This short-term project is to collect data to reinforce and application for funding from the National Institutes of Health.
