Postural Assessment And Biomechanics And Bones Flashcards
Down syndrome or autism patients may have
Flat feet ,
Flex or hyperextended knee
Greater than or equals to 45 is
A good posture
Less than 19 or 19
Very bad
Forces falling on the bones are
Compression forces
Traction forces
Bending and shearing
Torsional rotational force
Endurance of the bone has to do with
Resistance capacity against forces
Elastic feature
Compression forces are
Co linear - same plane
Co planar- same line
Same direction
Compression forces do what
Potension to shorten and widen the bone
Traction forces are
Co liner
Co planar
Opposite direction
And they lengthen and narrow the bone
Bending and shearing
Co plane
Same direction and different line
Bending- compresses and tensions the bone
Shearing- severs the bone
Organic substances in bones
Collagen and protein
Bone cells
Function of organic and inorganic substance
Organic provides flexibility
Inorganic( calcium and phosphate ) provides strength to bones
Bending force and tension-traction force forces on
Concave. Convex
Mineralization of bones depends on
The age and location
Porosity or spongy depends on
Amount of calcium phosphate and calcium carbonate
Function of utricle and saccule
Dynamic balance and posture
