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

neck posture with outward stretching of
 Chronic

 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.
Dr Shwetha S Hegde
 People
in the software field
 Surgeons
 Dentists
 Factory/high precision workers
 People with a desk job
 People with sedentary lifestyle-prolonged TV
watching
Dr Shwetha S Hegde
 Create
awareness among the target
population
 Counsel
them to develop better posture and
eliminate parafunctional habits
 Treat
the symptoms
