When a patient presents with 'tight' hamstrings, the default reaction is often to stretch them. However, in many clinical cases, this tightness is a protective tension managed by the nervous system. The brain restricts range of motion because it perceives a lack of stability in the joint, not because the muscle itself is physically short.
Stability Before Mobility
To unlock a joint, we must first prove to the nervous system that the joint is safe. This is achieved through specific strengthening at the end-ranges of motion. By building control in these vulnerable positions, we provide the stability necessary for the brain to release the protective tension, resulting in a permanent increase in functional mobility.
The Goal of Joint Centration
True mobility is the ability to maintain the center of the joint throughout a full movement arc. When a joint is centered, force is distributed evenly across the articular surfaces, reducing wear and tear. Our clinical focus should always be on quality of control rather than just the number of degrees on a goniometer.
