Are there some genetic reasons I get unsteady gait off and on?

See below. A normal gait is a very complex and fluid set of movements. The arms move synchronously with the opposite leg, the ankles nearly touch, and the heel strikes first. A normal gait requires the integration of the following systems: visual, vestibular, auditory, cerebellar, basal ganglia, sensory, and muscular. An abnormality in any one of the systems can cause a problem with gait and can lead to fall.
