Postures And Planes Lab Flashcards
What is the coronal plane axis of motion and plane motion?
- axis of motion= anterior/posterior
- plane motion= lateral flexion or side bending
What is the sagittal plane axis of motion and plane motion?
- axis of motion= right/left or transverse
- plane motion= flexion and extension
What is the transverse/horizontal plane axis or motion and plane motion?
- axis of motion= superior/inferior or longitudinal
- plane motion= rotation
What is an axis vs a plane?
- motion takes place within a plane about an axis
- axis= imaginary line about which motion occurs, axes are perpendicular to anatomic planes
What is the gravitational line?
- viewing patient from the side an imaginary line in a coronal plane which starts at or slightly anterior to the lateral malleolus, passes across lateral condyle of the knee, greater trochanter, lateral head of the humerus at tip of the shoulder to the external auditory meatus
- would intersect body of L2/L3 and anterior sacrum
Landmarks for gravitational line
- external auditory canal
- lateral head of humerus
- 3rd lumbar vertebrae
- anterior third of sacrum
- greater trochanter
- lateral condyle of knee
- lateral malleolus
What is postural decompensation?
-distribution of body mass away from ideal when postural homeostatic mechanisms are overwhelmed
-occurs in all planes
-failure of body to align
Ex) coronal= scoliosis, horizontal= rotation, sagittal= lordosis/kyphosis
What are 4 types of postural alignment?
- ideal
- kyphosis-lordosis
- flat back
- sway-back= decrease lumbar lordosis
What is important about osteopathic postural exam?
- MSK exam focus on static and dynamic response of body to gravity while erect
- pt stand on level surface w/o shoes
- all extermities extended
- feet 6-8 inches apart
- heels in same frontal plane
- examiners eyes at levels of body part being viewed and light palpation used
