Postural Assessment Flashcards
Position in which minimum stress is applied to each joint
Correct posture
Any static position that increases the stress on the joints.
Faulty posture

2nd MTT
The area within the points of contact of the body and any object individual relies on for support
Base of Support (BOS)
And imaginary vertical line that passes from the COG to the ground or surface the object or person is on.
Line of Gravity (LOG)
Line of Gravity for UE

When the LOG is within the BOS
Stable
When the LOG falls outside of the BOS
Unstable
How to increase stability
Larger BOS
Lower COG
