Which movement has Hard end feel at 0 degrees?

• A. Finger MCP flexion
• B. Shoulder internal rotation
• C. Elbow extension
• D. Wrist extension

Answer: (C)

Hard end feel happens when two hard surfaces come into contact and stop motion. At full elbow extension (0 degrees), the olecranon of the ulna fits into the olecranon fossa of the humerus, creating a bony block that prevents further movement. That is why elbow extension has a hard end feel at zero degrees. The other movements don’t typically produce a true bone-on-bone stop at full extension; they usually end with soft tissue compression or a firm capsular/ligament–driven end feel.
