opp exam 1

Center (Mid) gravity line

-midway between the feet

-extend superiorly up midline of spine

-divides body into 2 equal parts

-no rotation in horizontal plane

-no sidebending in the coronal plane

Center of gravity/weight bearing line travels through:

-just anterior to lateral malleolus

-just behind mid-knee

-femoral head

-ant 1/3 of sacral base

-middle of body of L3 vertebra

-external auditory meatus

• -head forward, cervical lordotic, thoracic kyphotic,
• scapulae abducted, lumbar spine lordotic, anterior pelvic tilt, hip joint
• slightly flexed, knee joints extended, plantar flexion of ankle joints in
• relation to angle of legs

• head forward, cervical spine lordotic, thoracic spine
• kyphotic, dec. lordosis of lumbar spine, post. tilt of pelvis, hips & knee
• joints hyperextended

• -head forward, cervical spine slight inc. lordosis, thoracic
• spine slight kyphotic in upper portion, then flattens in lower segments, lumbar
• lordosis flattened, hips/knees extended

• SLandmark
• assessment*

• SPostural
• analysis*

SActive ROM

SGait analysis

• Sbodies weight
• in relation to gravity over a base of support (structures from feet to skull)

• SBalanced
• configuration of the body

• SNormal arches
• of feet

• SVertical
• alignment of ankles

• SHorizontal
• orientation of sacral base

• SEqual
• distribution of body mass around the center of gravity

• SCompressive
• force on spinal discs is balanced by ligamentous tension

• SMinimal energy
• expenditure

• Spinal curves
• occurring from unilateral muscle contractions

• Curve
• disappears when muscle hypertonicity resolves

• Involves long
• term adaptation associated with positional changes

• Over time
• tissues associated with this curve change

• Tissues
• lengthen/shorten and resist change to the neutral position

*rotoscoliotic

Rotation & sidebending are occurring together

• Occurs in
• coronal plane
