We use 3 main systems to balance: our eyes, inner ears (Vestibular System), and joint sense of position or proprioception.  We can still function if some of them are not working at 100%; however, the more problems with each system we have, the more difficult it will become to balance.  Some patients lose balance due to muscle weakness.  this is more common in the elderly.  As a person begins to move less and less, the muscles begin to get smaller in size and length.  This usually contibutes to a flexed (bent over) posture, which further puts a person at risk for falling.

So, our muscles are important to keep us upright, but also to reduce the chance of a fall.  For example, if we stumble or get bumped, we have to take quick steps to stop ourselves from falling.  If the muscles are 'de-conditioned' (not in shape), we may not be able to step quickly enough to stop a fall.  If we are not standing straight, but leaning because of poor posture, gravity will try to pull us over.  

Therapy may be the answer to reduce falls!  A Physical or Occupational Therapist evaluates their patient's balance and tests muscle strength, range of motion, and posture.  They may also evaluate the systems that help us balance, and create a specific excercise plan to work on any body system that isn't working up to its potential.  (Balance Training)
