Balance is a highly integrated network vestibular system -rotatory stimulation and linear acceleration Information proprioceptive system -information input from the feet, ankle, hip and neck ocular system-visual perception of spatial orientation is supplied by the central nervous system -integrated these information and translated to fine motor movements
