What do R1 and R2 represent in joint end-feel assessment?

Explanation:
In joint end-feel assessment, you move the joint passively and note where resistance first starts and where a second, stronger resistance occurs as you approach the end of available motion. The first resistance barrier, R1, is the point at which tissue tension begins to be felt. The second barrier, R2, is the near-end point where further motion is limited by structures like ligaments or the joint capsule. This distinction helps describe how the joint is restricting movement and the quality of its end range. The end feel itself is the overall sensation at the end of range, not the two barriers; pain threshold or relaxation aren’t what R1 and R2 represent, and there’s no relevance to devices here.
