posture Flashcards
involves controlling the body position in space
postural control
is the ability to maintain appropriate relationships between body segments and between the body and the environment for successful task completion
postural orientation
the ability to control the COM in relationship to the BOS
postural stability
the point at the center of the total body mass
center of mass
the center of distributionof total force applied to the supporting surface
center of pressure
is obtained when the COM is over the BOS
postural stability
the vertical projection of the COM
center of gravity
strategies underlying stance postural control
sensory
sensorimotor
attentional
frontal cortex
motor cortex
higher level planning
brainstem
spinal networks coordinating muscle response synergies
coordination
motor neurons and muscles
generation
motor control of quiet stance
alignment
muscle tone
postural tone
strategies to regain anteroposterior stability
ankle strategy
hip strategy (with larger perturbations)
stepping strategy
senses contributing to postural control
visual
somatosensory
vestibular
how should you approach fall prevention
there is no one way
