Balance
Most of us think of balance as the ability to move without falling. Balance actually starts with the inner ear and eye movement. For some, those internal systems are not in sync.
There are two senses that affect body awareness and balance: Proprioception and Vestibular senses.
Trouble with body awareness and balance can have a big impact on motor skills. People who have trouble with proprioception or the vestibular sense could struggle with motor skills in a number of ways.
