Effects Of Neck Muscle Fatigue On The Vestibulo-Ocular Reflex, Amer Al Saif

Loma Linda University Electronic Theses, Dissertations & Projects

In order to maintain balance, the brain receives and processes input from multiple sensory systems including the visual, vestibular, and somatosensory systems. The information from these systems is sent to the brain where the information is then combined, organized and interpreted. This results in the output of reflexes (vestibulo-ocular reflex [VOR] and vestibulospinal reflex [VSR]). The VOR and the VSR work together with other motor systems to control gaze stability and control whole body equilibrium. Impairment in any of these sensory systems can result in dizziness, loss of balance, and visual instability. While the contributions of the visual, vestibular, and …
