9 POSTURE Flashcards
POSTURE
Position or attitude of the body.
Good posture-good body mechanics-energy conservation.
VERTEBRAL BODIES
Vertebral bodies & discs perform WB and shock-absorbing functions.
Facet joints & articular processes control movement.
Transverse and Spinous processes provide sites for muscle & ligament attachment
BONES, LIGAMENTS AND MUSCLES OF THE SPINE
SPINE CURVES
Natural curves in the back augment the strength of the spinal column by increasing the amount of compression the vertebrae can withstand.
FACET JOINTS
Slant and direction of the facet joints control mvmt in various regions of the spine.

POSTURAL SWAY
As we maintain our posture, we utilize our muscles to control the ‘postural’ sway.
PLUMB LINE IN STANDING IN NORMAL POSTURE
Opening of ear.
Acromion process.
Lumbar bodies.
Posterior of the greater trochanter.
Posterior patella.
Anterior to lateral malleolus.
JANDA’S UPPER & LOWER CROSSED SYNDROMES
Weak deep neck flexors, tight upper trapezius and levator scapula.
Tight pectoralis, weak lower trapezius and serratus anterior.
Tight erector spinae, weak abdominal.
Weak gluteus maximus, tight iliopsoas.
POSTURAL DEVIAITONS (10)
Lordosis.
Swayback posture.
Flat lower back (hypolordosis).
Flat upper back.
Kyphosis.
Scoliosis.
Forward head posture.
Flat neck posture/ military neck.
Kyphotic-lordotic posture.
Shoulder forward posture.
POSTURE AND PAIN
Faulty alignment causes undue stress/strain on bones, joints, muscles, and ligaments.
Joint positions can indicate which muscles are short or long.
Muscle shortness holds origin and insertion closer together.
Adaptive shortening can occur over time.
Muscle weakness allows separation of the origin and insertion.
Stretch weakness can occur in one-joint muscles that remain in elongated conditions.
EXERCISES FOR POSTURE CORRECTION
DNF strength.
Suboccipital stretches.
Lower Trap strength.
Pec Minor stretches.
Thoracic extension strength/mobility.
Glute strength.
Lower abdominal strength.
Hip flexor stretches.
