Chapter 2
 Posture is how the body balances.
 Muscles, bones, and ligaments all work together to
exert postural control.
 The nervous system innervates these structures to
regulate growth and function.
 Muscles and their nerves…
 A) provide stability to the trunk.
 B) produce movement during physiologic activity.
 The motor system consists of bones, muscles, and
ligaments.
 The nervous system controls the motor system.
 Postural analysis is an assessment of the function of
the motor system as well as the nervous system.
 The brain and nervous system utilize information from
three sources to balance the body in space.
 Sources of balance…
 Eyes – level.
 Ears – vestibular apparatus.
 Muscles and joints – proprioceptive pathways.
 A postural reaction that turns a falling animal's body
in space so that its paws or feet are pointed at the
ground.
 Returns the animal to sternal recumbency after being
placed on its back or side.
 A normal reaction is dependent on normal vestibular,
visual and proprioceptive functions.
 Postural changes can be the cause of a clinical
problem.
 Postural changes can be the effect of a clinical
problem.
 Orthopedic problems can cause a postural change,
which can worsen the orthopedic problem.
 Asymptomatic postural problems can produce
mechanical stress, which can predispose an
individual to injury.
 There is no “normal” posture.
 Ideal posture serves as a reference point.
 Ideal posture…
 Distributes gravitational stress for balanced muscle
function.
 Allows joints to move in their mid range to minimize
stress on ligaments and articular surfaces.
 Effective for the individual’s activities of daily living.
 Allows the individual to avoid injury.
 Good habits contribute to a strong and stable posture.
 Bad habits contribute to poor posture and instability.
 Excessive sitting.
 Carrying a heavy backpack.
 Slumping.
 Poor sleeping positions.
 One-sided activities…
 Carrying a heavy purse.
 Sitting on a wallet.
 Sitting in a twisted position.
 Overstressed muscles tighten.
 Favored muscles weaken.
 This imbalance perpetuates the poor posture.
 Anterior to posterior.
 Lateral.
 Helical.
 Foundational distortions create changes above.
 Palpate for hypertonic (overused) muscles.
 Palpate for weak / inhibited muscles.
 A muscle is weak because it is unstressed and should
be strengthened with exercise.
 An inhibited muscle is not being used because it’s
antagonistic muscle is being overused.
 Reciprocal inhibition describes muscles on one side of
a joint relaxing to accommodate contraction of
muscles on the other side of a joint.
