Stability and Motor Control Dysfunction

A term used within Functional Movement Systems to describe the intricate interplay between muscle tone, proprioception, balance, posture, breathing, the CNS, motor programs, and movement organisation.

Often, when looking at global or isolated joint movements we see differences in active and passive ranges or changes in mobility depending on posture. An athlete that can’t touch their toes while standing may have a 5cm overreach on the sit-and-reach test. This is an example multisegmental flexion Stability or Motor Control Dysfunction (SMCD). It is not a mobility problem in the traditional sense. It is the interplay between the various movement systems that creates the difference. There is no tissue extensibility or joint mobility problem to address, but a motor control problem.
