Postural Control Flashcards
The cycle of postural control
Goodposture Against antagonist muscle power Flexible antigravity muscles Body awareness Strong joint structure
In postural control the musculoskeletal system is supported by
Vestibular
Proprioceptive system
Cerebellar
Visual
What is postural orientation
Correction or being in a more suitable posture by means of established postural control during a static or dynamic action
Postural orientation is divided into
Environmental information (external) Bodily information (internal)
Conditions for balance
Support surface should be wide
Gravity center should be close to the support surface
Gravity line should pass from gravity center
Gravity line should be in the support surface
Balance strategy includes
Hip strategy
Ankle strategy
Suspension strategy
Stepping strategy
Control of vestibular system comprises of
Semicircular canals : utricle & saccule
Vestibular nucleuse in midbrain
Vestibular tract pathways
Control of visual system is divided into
Afferent motion perception
Efferent motion perception
The postural control is preserved
At conscious and unconscious levels
Utricle is sensitive to
Linear accelaration
Foward backwards,, running, sprinting , walking
Saccule is responsible for
Vertical movement
Jumping standing sitting
What should we control to have good postural sense
Posture- position- coordinated movement
