Posture Body Alignment

• Posture is defined as the position the body or
  parts of the body that necessitates a minimum
  amount of energy to sustain a mechanically
  efficient function of the joints and muscles.
• Incorrect posture can result in chronic pain and
  potential injury
• Line of gravity (LOG) goes through the center of
  most joint axies

3
Results of good posture

• Proper alignment of vertebral column
• Improved balance
• Overall balance of the muscles
• Optimal performance in daily activity

4
Center of gravity

• COG the point where all forces acting on the
  body are at equilibrium.
• LOG travels vertically straight through the COG
• Performing postural assessments requires a
  knowledge of the ideal LOG for proper posture

5
Static Versus Dynamic Posture

• Static posture- not moving (i.e. sitting or
  standing)
• Dynamic posture- moving body segments (i.e.
  walking or running)
• Injuries can occur when either form of posture is
  improper alingment for a prolonged period of
  time.

6
ROM

• Defined as the amount of motion that occurs
  around a joint
• Starts in anatomical position (0?)
• Active Range of Motion (AROM)
• Performance without assistance
• Pain free
• ROM assessment should be stopped if the client
  experiences any pain or discomfort
• Joint function and ROM depends the type of joint.

7
Goniometry

• Goniometry provides
• ROM data
• A determination muscular imbalances
• a ROM baseline
• Assistance in establishing ROM goals
