Taking Good Balance for Granted

It's Not Until Dizziness Becomes a Problem That We Notice How Important Our Balance Is To Us

According to the Vestibular Disorders Association (VEDA), the body maintains balance with sensory information from three main systems:

  • Vision
  • Proprioception (touch sensors in the feet, trunk, and spine)
  • Vestibular system (inner ear)

The Brain Integrates Sensory Information to Help Us Keep Our Balance

These three systems send information to the brain, and in response, the brain figures out where you are in space and sends information to the eyes for steady vision, and to the muscles for balance. When your balance system is working properly, you feel normal when you are standing or moving around:
  • you can keep your balance when you're doing different activities
  • you can see everything clearly when you move around
  • you don't give a second thought to whether or not you should move your head
But when the balance system isn't working, even small activities like walking on uneven ground or walking down the stairs can be challenging and even cause an accident.
When the balance system isn't working, walking down the stairs can be challenging

Conflicting Information to the Brain Causes Disorientation

If the brain is getting conflicting sensory information from the vestibular system, the eyes, muscles or joints, it is difficult to process it. The goal of vestibular rehabilitation is to correct problems in the inner ear, or create a treatment program for you that will help the brain re-establish the coordination between your inner ears, eyes, muscles and joints.
