Details the special considerations required for vision correction, including glasses and contact lenses. 2020-11-16 · Observation of myotactic and vestibulo-ocular reflexes Introduction The purpose of this experiment was to study the anatomy of human reflexes, specifically to compare monosynaptic reflexes to polysynaptic reflexes. The monosynaptic reflex in this experiment is the myotactic, or Hoffman, reflex that 2020-08-10 · Assessment of the vestibulo-ocular reflex takes place using the Halmagyi-Curthoys test, also known as the rapid impulse test. To perform this, the physician will rapidly move the patient’s head in one direction (left or right), and the eyes should remain in place focused on a particular object in front of them despite the head movement. The video head impulse test, in which the vestibulo-ocular reflex is tested, can reveal an early specific sign of selective dysfunction in the medial vestibular nuclei by demonstrating selective dysfunction of the horisontal vestibulo-ocular reflex.

For a review, we refer to a previous paper on this subject (Huygen, 1983). Since this previous study, we learnt more about normal and abnormal rotatory responses and therefore we decided to study the vestibulo-ocular reflex (VOR) again in an entirely new group of patients. A more thorough vestibular analysis is now attempted.

This is known as gaze stability. The VOR also sends a signal down to the postural muscles of the trunk/arms/legs, which is crucial for maintaining balance.
