Anatomic Barrier limits which ROM?

Explanation:
The key idea is that the anatomic barrier is the physical limit imposed by the joint’s passive structures—bones, ligaments, joint capsule, and articular surfaces. This boundary defines the maximum motion you can achieve when the joint is moved passively, with no active muscle contraction. So the anatomic barrier limits passive range of motion. Active range of motion, by contrast, can be limited earlier by muscle strength, motor control, or pain, and the end feel describes the quality of resistance at the limit, not the limit itself.
