The Finger Flexion Sign is a simple yet powerful clinical test for assessing ulnar nerve integrity, especially in cases of cubital tunnel syndrome or suspected interosseous muscle weakness. In this short video, observe how placing a piece of paper between the middle and ring fingers and pulling it distally can reveal compensatory MCP joint flexion, a positive sign of dysfunction. 📽️ Access the full video in the Physiopedia Plus library: 🔗 View the full video library https://members.physio-pedi

The percentage contribution for ulnar deviation is calculated by dividing an individual muscle’s torque by the sum of all muscles involved. According to the Holzbaur et al. (2005) model, we determine raw force through PCSA (the total area of muscle fibers), which is 2.1 cm^2 for the ECU and a beefier 2.9 cm^2 for the FCU. However, leverage makes a difference. The moment arm is a measure of mechanical advantage measured by tracking how far a tendon moves during rotation (Garland et al. (2018). Be
