Coordination Exam: Normal Exam: Station (x2) (includes Spanish audio & captions) | Have the patient stand still. Note the position of the feet and how steady the patient is with eyes open. In the demonstrated exam, the patient is asked to hop and pat at the same time. This is a good way to test upper and lower extremity coordination and balance simultaneously. NeuroLogic Exam has ... | Coordination Examination; Station | NeuroLogic Exam: An Anatomical Approach |

Cranial Nerve Exam: Abnormal Examples: Vergence (x2) | Light-near dissociation occurs when the pupils don't react to light but constrict with convergence as part of the near reflex. This is what happens in the Argyll-Robertson pupil (usually seen with neurosyphilis) where there is a pretectal lesion affecting the retinomesencephalic afferents controllin... | Cranial Nerve Examination | NeuroLogic Exam: An Anatomical Approach |

 |
Coordination Exam: Abnormal Examples: Check Reflex (includes Spanish audio & captions) | The patient is unable to stop flexion of the arm on sudden release so the arm may strike the chest and doesn't recoil to the initial position. This is most likely due to failure of timely triceps contraction.

Cranial Nerve Exam: Abnormal Examples: Cranial Nerves 9 & 10 - Motor (x2) | When the patient says ah there is excessive nasal air escape. The palate elevates more on the left side and the uvula deviates toward the left side because the right side is weak. This patient has a deficit of the right 9th & 10th cranial nerves.

Cranial Nerve Exam: Abnormal Examples: Cranial Nerve 2 - Visual Acuity (x2) | This patient's visual acuity is being tested with a Rosenbaum chart. First the left eye is tested, then the right eye. He is tested with his glasses on so this represents corrected visual acuity. He has 20/70 vision in the left eye and 20/40 in the right. His decreased visual acuity is from optic ne... | Cranial Nerve Examination | NeuroLogic Exam: An Anatomical Approach |
