Linköping University, Department of Clinical and Experimental Medicine, Technical Audiology. Smooth pursuit (SP) maintains visual acuity of slow-moving objects by keeping their image near the fovea. SP impairment is recognized by saccadic pursuit and occurs toward the side of lesions at the parietal, occipital, and temporal lobe junction (area V5); the frontal eye field and their projections to the basal pontine nuclei; paraflocculus; and caudal cerebellar vermis. The smooth-pursuit eye-tracking test is useful in evaluating drug toxicity, central nervous system tumors, posterior or middle cerebral artery thrombosis, enceph alitis, whiplash injury, and parkinsonism [3]. Both tests (saccades and eye-tracking) are rarely pathological in peripheral vestibular damage. Based on these observations, some investigators have suggested that the fixation suppression test is a test of the smooth pursuit system and nothing more (Barnes, Benson, and Prior, 1978).

Smooth pursuit test

About 10% of normal, sober individuals have lack of smooth pursuit, but they will not be tested at a traffic stop unless the officer suspects impairment. b. Smooth pursuit eye tracking test is a useful one in drug toxicity, central nervous system tumors, posterior or middle cerebral arteries thrombosis, encephalitis, whiplash injury, Parkinsonism. The test is rarely patholo-gical in the peripheral vestibular damage, but the strong spontaneous nystagmus can produce abnormalities of pendular eye movement. Smooth Pursuit Exercises “Follow the Kitty” The exercises are much like the tests.

Smooth pursuit, or just pursuit, is a class of 14 Jan 2020 Smooth pursuits are just one of the metrics that can be measured using eye tracking, and even alone they offer great insight into a patient's In smooth pursuit tracking, the patient is instructed to follow a sinusoidal moving target with his or her eyes only.

Have them follow as you move a stickered pencil slowly. Go to the right, and back to the center 10 times. Then to the left and back to center 10 times. It should take about 8 seconds to … SPNT - Smooth Pursuit Neck Torsion Test.

2007-04-09 These include greater lag during smooth pursuit tracking and lower gain of pursuit velocity in subjects with mTBI and PCS symptoms [19,27]. To investigate smooth pursuits, researchers often utilize circular tracking tests, a type of predictive visual tracking that necessitates attention and working memory [22].As If playback doesn't begin shortly, try restarting your device.

The test is rarely patholo-gical in the peripheral vestibular damage, but the strong Objective . This study aimed to determine how the smooth pursuit neck torsion (SPNT) test is affected by various diseases associated with disturbances in balance and arising in the neck, in the posterior intracranial fossa, and in the labyrinth in patients having such conditions, and to compare the findings with those in healthy subjects. The smooth pursuit neck torsion test was performed and analysed taking into account subjects' reported levels of pain, anxiety and dizziness. The results confirm that there are significant The smooth pursuit neck torsion test is thought to be a measure of neck afferent influence on eye movement control and is useful in assessing subjects with whiplash, especially those complaining In smooth pursuit test most often second degree (35.0%), in OKN test first degree (28.3%) and in saccades the third degree (31.6%) of dysfunction was observed.
