Postural Assessment Flashcards
Posture
manner on how we sit, stand, kneel, etc.
relative disposition of the body at any moment and composite positions of the different joints of the body at the same time
skeletal alignment in a state of balance
protects the supporting structures of the body against injury or progressive deformity
how we carry ourselves
Bad Posture
may not be biochemically sound
commit different errors especially during long hors
Primary Curves
curves found at birth
sacral and thoracic spines
Secondary
curves appear when child grows
cervical and lumbar spines
at 8 months curvatures must be formed completely
Cervical Spine
cervical lordosis (convex forward)
appears at three months when child looks up from prone position
Lumbar Spine
lumbar lordosis
appears at 6
6-8 months old when a child learns how to sit
Body Mechanics
ability to produce a motion that is safe, energy conserving, and anatomically and physiologically efficient
maintenance of a person’s body balance and control in an optimal balanced position
Balance
constant adaptation of forces to attain dynamic equilibrium before adapting and establishing a new equilibrium
achieved when center of gravity rests within the base of support (state of stability)
Equilibrium
condition of balance among forces acting within or upon a body
Center of Gravity
imaginary point in the body where all the forces acting upon it are balanced
changes as the body moves
COG of Adults
one inch anterior to S2
COG of Infants
xiphoid process/ T12
Base of Support
area which an object rests and provides stability for the object
Level of Stability
minimal displacement: still under BOS
moderate perturbations/ displacements: shifting of weight to bring body back to COG
maximum perturbations: stepping strategies
Line of Gravity (Anterior)
Head: middle of forehead, nose, and chin
Neck/ Shoulders: midline of neck and shoulder
Chest: middle of xiphoid process
Abdomen/ Hips: umbilicus
Hips/ Pelvis: equidistant from the two ASIS and through symphysis pubis
Knees: between the knees equidistant from the medial femoral condyles
Ankles/ Feet: equidistant from the medial malleoli (feet positioned shoulder-width apart)
