Exam 1: Posture Analysis Flashcards
_______: Position or attitude of the body that requires minimum muscular energy to maintain mechanically efficient function of joints and musculoskeletal balance.
Posture
True or false:
-Static posture is a neuromuscular-skeletal event.
True
Influences on Posture

Must Understand Poor Posture First!
*Zero and anatomical joint positioning can reveal tight or elongated muscle structures.
- Adaptive shortening
- Distance between origin and insertion [increases/decreases].
- Muscle weakness
- Distance between origin and insertion [increases/decreases].
*Limited _____ Range of Motion
decreases
increases
Joint
Kinetic Chain
*You are as strong as your _______ link.”
- Kinetic Chain is comprised of
1) Ankle/foot complex
2) Knee
3) Hip
4) Vertebral Column
5) Shoulder
*One segment in the kinetic chain becomes out of alignment, the other structures have to over __________ to balance the weight distribution from the dysfunctional structure.
weakest
compensate
Concepts
- Anatomical Position
- Position of reference.
- _____ posture, with face forward, arms at sides, palms forward and fingers extended.
- Zero Position
- Same as anatomical position except the _____ face toward the body and the forearm is semi-________.
- Zero posture is equilibrium in the body where all internal forces equal ____.
Erect
hands
pronated
zero
Concepts
- Center of Gravity (COG)
- Point where the weight of the body is ________.
- Line of Gravity (LOG)
- Vertical line transecting the ______ of gravity.
- Base of Support (BOS)
- Parts of the body in contact with the supporting surface; the _____ the base of support, the greater the stability of the erect body; the center of gravity is more easily maintained through a stable base of support.
concentrated
center
wider
Posture Dysfunction
- Muscular imbalances
- Restricted Range of Motion
- Asymmetries
=
- Force Production Limited
- Movement Efficiency Decreased
- Poor Stabilization
