Abstract
This independent study in Dr. Lake’s Musculoskeletal Soft Tissue Lab focused on two main projects. The first was creating a platform and harness system to secure a rat while its elbow range of motion (ROM) was measured in vivo. Multiple prototypes were designed, 3D printed, and tested on a deceased animal, and each design was improved upon to yield more consistent results. The final prototype yielded semi-consistent results, with further improvements identified and planned. The second project focused on developing a protocol to confirm the integrity of a rat’s ulnar nerve after an ulnar collateral ligament (UCL) transection. Two methods for confirming nerve integrity were investigated: paw pricking and electrical stimulation. The electrical stimulation method was selected, and a stimulation device was chosen and obtained to test in a live animal in January 2025.
