What happens
when we work on a computer ?
• Distribution of weight.
• Our heads are very
heavy.
• 1/ we reduce the
normal curve of our
lower back ( lordosis)
maintain the balance
of the body
• spine
• legs
• neck
• muscles
and joints.

2/pectoral muscles
• Shortened pects
cause the shoulders
to roll forward
• This along with
muscle fatigue cause
head forward
movement
• The result is strain on
the neck
• The main stabilizer
of hand position is
the pect muscles
• after hours :
weak+ short

3/ lower neck and upper back
• stress is transferred
at there.
• contains a complex
network of nerves
that go to your arm
and hands
• Reduced strength
in arm and hand
• Changes in
sensation
• Changes in
reflexes

4/ Brain
• If the neck is not in its proper
alignment vessels (Vertebral
artery ) are
compromised and the brain
gets a decreased blood
flow which in turn causes
headaches.
Vertebral artery
