Posture and Movement System Margo Prim Haynes, PT, DPT, MA, PCS Mary Rose Franjoine, PT, DPT, MS, PCS Posture and Movement Functional skills are controlled by two different but complementary subsystems, one for posture and one for movement. 2009 Prim Haynes & Franjoine 2 What is Posture? 2009 Prim Haynes & Franjoine 3 Functions of Postural System Maintain alignment of the body by overcoming the effects of gravity in all positions at all times (postural tone) Preserving joint integrity Maintain COM within BOS Prepare the body for movement 2009 Prim Haynes & Franjoine 4 What is Movement? 2009 Prim Haynes & Franjoine 5 Function of Movement System Provide mobility of various body segments in space. Initiation Continuation / (sustain) Termination 2009 Allows expression of well timed, coordinated, sequenced fluid movement Prim Haynes & Franjoine 6 To Climb 2009 Prim Haynes & Franjoine 7 we need both systems to work efficiently but most importantly…… ……together 2009 Prim Haynes & Franjoine 8 What functions allow for each system to be unique and role specific? 2009 Prim Haynes & Franjoine 9 The Role of the Muscles Postural System Movement System Bi Pennate Multi Pennate Uni- Pennate Penniform Attachment Angular Parallel Fiber Length Short & Broad Long & Slender Configuration 2009 Prim Haynes & Franjoine 10 Multifidus Muscle Postural System http://en.wikipedia.org/wiki 2009 Prim Haynes & Franjoine 11 Movement System http://en.wikipedia.org/wiki 2009 Prim Haynes & Franjoine 12 Gluteus Medius http://en.wikipedia.org/wiki 2009 Prim Haynes & Franjoine 13 Duel Role of Gluteus Medius 2009 Prim Haynes & Franjoine 14 The Role of the Peripheral Nervous System = Motor Units Posture System Unit type: S Slow to fatigue Contraction speed slow Rich capillary action 2009 Movement System Motor unit types FR resist fatigue FF fatigue rapidly Prim Haynes & Franjoine 15 What is…. Postural Control? Balance ? Functional Balance? 2009 Prim Haynes & Franjoine 16 Postural Control Steady State Postural Control Maintain the COM within BOS Sway Strategies Dynamic Postural Control Anticipatory: Prepares Reactive Righting & Equilibrium Reactions Modifies Response due to environment Proactive & Task 2009 for movement (feedforward) Prim Haynes & Franjoine 17 Postural Control Interaction of Multi-systems that influence the motor output Response ….. 2009 Prim Haynes & Franjoine 18 …Balance Balance what we see and measure clinically How we measure Balance? Steady State Balance Anticipatory Balance Proactive Balance Reactive Balance 2009 Prim Haynes & Franjoine 19 Functional Balance is… Integration of the postural and movement system which allows us to freely move in space to complete our desired functional tasks with orientation of the body in space and fluid execution of the movement.
