Abstract

Tearing of the ulnar collateral ligament (UCL) is one of the most common injuries for baseball pitchers. During a pitch, the UCL experiences high levels of stress between the cocking and acceleration phase. Because this stress cannot be directly measured in vivo, a pitching robot with many biomimetic features was created to gain a better understanding of these forces. This robotic research platform was then used to design a brace that reduces the amount of stress the ligament undergoes, potentially prolonging the play time for athletes. The robotic arm featured seven independently, pneumatically actuated Hydro Muscles and a biomimetic UCL. When the brace was used on the robotic arm, the force on the artificial UCL decreased during the pitching phases which validated its effectiveness.
