Although very simple, balance exercises can greatly strengthen your center of gravity. Any exercise that is done on one leg can be considered a balance exercise. Standing on one leg will improve your body's ability to center its mass over one leg.
The body's center of gravity may change over the years, causing a change in the degree of knee flexion needed to maintain one's balance when walking. Some individuals with neuromuscular disorders walk with a shuffling gait or move with lurching actions. At times a gait disorder may be the result of a medication that causes confusion or loss of coordination or an eye or ear disturbance that affects the sense of balance.
