13 Cranial Nerve Exam: Abnormal Examples: Cranial Nerve 7 - Sensory, TasteThe patient has difficulty correctly identifying taste on the right side of the tongue indicating a lesion of the sensory limb of the 7th nerve. NeuroLogic Exam has been supported by a grant from the Slice of Life Development Fund at the University of Utah, the Department of Pediatrics and the Offic...Cranial Nerve ExaminationNeuroLogic Exam: An Anatomical Approach
14 Coordination Exam: Anatomy: Midline Ataxia (includes Spanish audio & captions)Clinically, the ataxic syndromes caused by vestibulocerebellar and spinocerebellar disease are lumped together and are called midline or equilibratory (gait) ataxias. The hallmarks of these midline ataxic syndromes are truncal instability manifested by titubation (tremor of the trunk in an anterior-...Coordination Examination; Anterior Lobe of Cerebellum; Flocculonodular LobeNeuroLogic Exam: An Anatomical Approach
15 Coordination Exam: Abnormal Examples: Speech - Rapid Alternating Movements - Dysarthria (x2) (includes Spanish audio & captions)Impaired speech articulation of cerebellar origin is characterized by being slow, indistinct, and scanning (scanning refers to decomposition of words into monosyllabic parts and loss of normal phrasing and intonation). NeuroLogic Exam has been supported by a grant from the Slice of Life Development ...Coordination ExaminationNeuroLogic Exam: An Anatomical Approach
16 Cranial Nerve Exam: Abnormal Examples: Cranial Nerve 11 - MotorWhen the patient contracts the muscles of the neck the left sternocleidomastoid muscle is easily seen but the right is absent. Looking at the back of the patient, the left trapezius muscle is outlined and present but the right is atrophic and hard to identify. These findings indicate a lesion of the...Cranial Nerve ExaminationNeuroLogic Exam: An Anatomical Approach
17 Coordination Exam: Abnormal Examples: Station (x2) (includes Spanish audio & captions)Patient's feet will be placed wider apart then usual in order to maintain balance (broad or wide-based station). Midline ataxias cause instability of station with eyes opened or closed. NeuroLogic Exam has been supported by a grant from the Slice of Life Development Fund at the University of Utah, t...Coordination Examination; StationNeuroLogic Exam: An Anatomical Approach
18 Coordination Exam: Abnormal Examples: Hand - Rapid Alternating Movements (x2) (includes Spanish audio & captions)Movements are slow and irregular with imprecise timing. Inability to perform repetitive movements in a rapid rhythmic fashion is called dysdiadochokinesia.

19 Gait Exam: Abnormal Examples: Hemiplegic Gait DemonstrationThe patient has unilateral weakness and spasticity with the upper extremity held in flexion and the lower extremity in extension. The foot is in extension so the leg is too long therefore, the patient will have to circumduct or swing the leg around to step forward. This type of gait is seen with a U...Gait Examination; Hemiplegic GaitNeuroLogic Exam: An Anatomical Approach

It fine-tunes the force of agonist and antagonist muscle activity simultaneously and sequentially across multiple joints to produc...Coordination ExaminationNeuroLogic Exam: An Anatomical Approach
23 Cranial Nerve Exam: Abnormal Examples: Cranial Nerves 2 & 3 - Pupillary Light Reflex (x2)The swinging flashlight test is used to show a relative afferent pupillary defect or a Marcus Gunn pupil of the left eye. The left eye has perceived less light stimulus (a defect in the sensory or afferent pathway) then the opposite eye so the pupil dilates with the same light stimulus that caused c...Cranial Nerve Examination; Marcus Gunn PupilNeuroLogic Exam: An Anatomical Approach
24 Coordination Exam: Abnormal Examples: Finger-to-nose (includes Spanish audio & captions)Under (hypometria) and over (hypermetria) shooting of a target (dysmetria) and the decomposition of movement (the breakdown of the movement into its parts with impaired timing and integration of muscle activity) are seen with appendicular ataxia.
