Introduction to Postural Dysfunction/Movement Impairment

By Brent Brookbush DPT, PT, COMT, MS, PES, CES, CSCS, H/FS



  • Ideal Posture - Ideal arthro- and osteo-kinematics maintained by optimal myofascial activity and length, as a result of accurate sensation, integration and activation by the nervous system - both statically and dynamically.
  • Postural Dysfunction - The absence of ideal posture as a result of maladaptation by one or multiple tissues within the human movement system.

    • Example, rounded shoulder posture (RSP) and altered motion post surgical intervention for shoulder impingement syndrome (SIS), both result in compensatory patterns that may be termed "postural dysfunction." "Movement impairment" is a synonym for "postural dysfunction."

Postural Dysfunction, Movement Impairment, Human Movement Science and Predictive Models:

The articles in the category “Postural Dysfunction & Movement Impairment” are my attempt to refine previously published models of postural dysfunction and movement impairment. The goal is to improve the power of these models to accurately predict an optimal set of assessments, manual techniques, exercises, and outcome measures with the goal of improving posture, reducing the risk injury, enhancing sports performance and optimizing rehabilitation. As an educator, I believe these models provide an excellent
