presentation on POSTURAL CONTROL AND MOVEMENT SYSTEMS

1. POSTURE AND MOVEMENT SYSTEMS

2. INTRODUCTION Functional activities are controlled by two different but complementary systems Postural system Movement system

3. POSTURAL SYSTEM Maintain alignment of body in any position Anticipate changes to allow goal directed movements and make adjustments before, during and after movement Tries to Maintains COM with in BOS Protects the integrity of joints

4. MOVEMENT SYSTEM Provide range and speed to motor function Mobility To overcome the inertia Energize the initiation Decelerate the termination Transfers To translate the body segments in space Progression, stability and adaptation

5. Characteristics Postural system Movement system Muscle configuration Bi/multipinnate Unipinnate, penniform Muscle fiber length Short Long Number of joints the muscle crosses Single Two or more Muscle attachments Broad Narrow Muscle placement Deep Superficial Muscle fiber type STO FTO,FTG Fatigue Slow Fast Contraction speed Slow Fast Capillary network Very rich Rich Type of muscle contraction Slow, sustained, short range, Fast, rapid, quick, short burst, large range Proprioceptive feedback Requires continuously Requires

6. Examples of postural and movement muscles Postural Movement

7. POSURAL CONTROL Steady state Anticipatory Adaptive Reactive Righting reactions Equilibrium reactions Protective reactions

8. Some important requirements for designing the treatment Centre of gravity Line of gravity Base of support Alignment Symmetry Characteristics of normal movement Weight bearing and weight shifting Planes of movement Biomechanics Motor control / motor learning Anatomy and physiology of neuromuscular system
