Components of balance (static and dynamic)

Components of balance (static and dynamic)

• 1.
  COMPONENTS OF BALANCE.
• 2.
  WHAT IS BALANCE? •Control of centre of mass over the base of support. • The overall goals of balance is to control system stability, function and integrated CNS control.
• 3.
  COMPONENTS OF BALANCE •The 3 components of balance comprise of the : 1. Visual system 2. Proprioceptive system 3. Vestibular system
• 4.
  • The brainintegrates and processes all the information from these 3 systems to help us maintain our balance. • When you start to have problems with your balance one or more of the above systems might be affected.
• 5.
  VISUAL SYSTEM Receptors inthe retina are called rods and cones. When struck by light, the receptors send impulses to the brain that provide visual feedback on how a person is oriented relative to other objects .
• 6.
  VESTIBULAR SYSTEM • Thevestibular system in each ear is made up of the utricle saccule and 3 semicircular canals .The utricle and saccule detect up down and side to side movements .The semicircular canals detect rotational movement.When the head rotates in the direction sensed by a particular canal, the receptors in that canal sends impulse to the brain about movement.
• 7.
  • When thevestibular organs on both sides of the head are functioning properly.They send symmetrical information to the brain.
• 8.
  PROPRIOCEPTIVE SYSTEM • Sensory/Mechanoreceptors from the skin,muscles and joints are sensitive to stretch, pressure and movements. • With any movement of the body, the receptor respond by sending impulses to the brain which then interprets this movements. • This is how even with your eyes closed you can tell if your elbow is straight or bent or which way your head is turned.
