A
major postural imbalance
Anterior
positioning of the cervical spine
Common
occupational hazard
Dr Shwetha S Hegde
Poor
posture
alters spine position
mandible shifts forward
the upper and
lower teeth misalign
skull moves back on
the spinal column.
If
not addressed, pain and inflammation in the
muscles and jaw joints will develop when the
mouth opens and closes.
Forward
Head Posture (FHP) is a very common
postural issue, and it is estimated to occur in
between 66% and 90% of the population.
Dr Shwetha S Hegde
Mandibular
posture and head posture are inversely
proportional in an antero-posterior (forwardbackward) plane.
Shifting
the mandible backward causes the head to
shift forward, and shifting the head forward causes
the mandible to shift backward.
Dr Shwetha S Hegde
FHP is strongly correlated with backward mandibular posture. TMJ
disorder patients typically have both FHP and backward mandibular
posture.
Dr Shwetha S Hegde
FHP
Protective
mechanism
Decreased resting
freeway space
Increases passive
tension in
muscles of
mastication
Backward mandibular
posture
Dr Shwetha S Hegde
Head
and jaw posture are both controlled by
a hierarchy of neuromuscular reflexes, and
airway protection is top priority.
For
every inch the neck goes forward there is
an extra 4.5 kg of weight on the neck.
Dr Shwetha S Hegde
FHP
produces a progressive loss and then a
reversal of the normal cervical curve
(lordosis) of the neck
Dr Shwetha S Hegde
Changes occurring in the curvature of
the spine over time due to FHP
Dr Shwetha S Hegde
FHP
causes realignment of the curvature of
the spine due shifting of the weight of the
head.
The
weight is distributed unevenly on the
intervertebral spine causing compressive
strain on the intervertebral disc
This
leads to stiffness and arthritic changes in
the spine
Since
muscles function in groups, muscles
determining posture are also affected
Dr Shwetha S Hegde
Pain
in the muscles of mastication and
infrahyoid muscles
Pain
in the TM joints
Change
in occlusion due backward shift of
the mandible
Dr Shwetha S Hegde
Stress
worsens muscle tension by a
measurable decrease in muscle circulation
Brings
down threshold for jaw muscle pain
due to inhibition of endorphin release
Dr Shwetha S Hegde
Attitude
influences posture and resting
muscle tensions in the jaw area just like it
does in the rest of the body.
Dr Shwetha S Hegde
Chronic
neck pain
Headaches
Tingling
and numbness in the arms and hands
Improper
Poor

breathing
neck posture with outward stretching of
Chronic
fatigue
Dr Shwetha S Hegde
Re-establishing
a stable balanced resting posture
for the head and the mandible.
Has
mechanical and psychological components.
Mechanical
component- paying attention to
posture while standing, sitting sleeping etc
The psychological component involves the way
your mental state affects the resting postures of
your muscles and thereby also the stance you
use for weight bearing.
Dr Shwetha S Hegde
EXERCISE
STRETCHING
PASSIVE
PHYSICAL SUPPORT
Dr Shwetha S Hegde
Anti
inflammatory drugs
Ultrasound
TENS
Cortisone
Use
injections
of neck brace
Dr Shwetha S Hegde
Neck
exercises because the neck muscles are
the primary determinants of head posture.
Resistance
exercises to strengthen neck
muscles
Dr Shwetha S Hegde
Yoga,
Tai Chi, and swimming are popular
exercises which provide both stretching and
strengthening.
Another
way to combine strengthening with
stretching is to pull oneself upward using
overhead bars.
Dr Shwetha S Hegde
Ergonomically
perfect chair
A
simple foam rubber mattress or a relatively
hard mattress is preferable
Passive
support using a pillow under the neck
Dr Shwetha S Hegde
Make
•
•
sure your computer monitor is
ergonomically set up.
top third of your screen is at eye-level.
distance from your monitor to your eyes to
should be 18 to 24 inches
Never
carry heavy bags, backpacks or
purses
Dr Shwetha S Hegde
Get
up and walk around every half an hour
that you work at a desk, work in front of a
computer or watch television.
Buy
a supportive neck pillow, if you often
wake up with a sore neck.
