Which movement has 0-90 degrees range with Hard or Firm end feel?

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

Answer: (A)

The movement being tested is finger MCP (metacarpophalangeal) flexion. This joint commonly moves from full extension to about 90 degrees of flexion, giving a 0–90 degree range. The end feel at that end range is firm, not soft or hard, because the joint is held in place by the tension of the volar plate and the collateral ligaments around the MCP joint, along with the joint capsule. These soft-tissue structures limit further motion as you approach 90 degrees, producing a firm end feel.

The other options don’t fit this pattern: shoulder internal rotation typically does not reach 90 degrees in standard clinical measures; wrist extension usually ends well below 90 degrees; elbow extension has a different ROM pattern (often measured from full extension toward flexion, not 0–90), and its end feel at the limit isn’t the MCP’s typical firm end feel.
