The SPNT test is a smooth pursuit eye movement test. The subjects are placed in a neutral position, and then they turn 45° to the right and to the left. The difference between the average gain in neutral and torsion positions is the test parameter.

slower then VOR Gain testing Hold the patient’s head stationary. Have the patient follow your slowly moving finger horizontally (from center to 30 degrees right and then to 30 degrees left), and then vertically (center to 30 degrees up to 30 degrees down). Vestibular Testing: Smooth Pursuit . The smooth-pursuit test (also known as sinusoidal or oscillating tracking) is performed with the patient seated in front of a light bar. The patient is asked to “follow the lights” while holding their head perfectly still. DiVA portal is a finding tool for research publications and student theses written at the following 49 universities and research institutions. Objective: 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 of … Smooth pursuit (SP) maintains visual acuity of slow-moving objects by keeping their image near the fovea.

in patients using a new technique to test these cognitive controls. Methods: Twelve patients treated at the Department of Otolaryngology at our hospital underwent SPEM testing using both electronystamography (ENG) and VOG. Post hoc tests showed that these parameters were different between children aged 7 or younger and adults.

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.

Lo smooth pursuit (SP) è una deviazione angolare dei bulbi oculari coniugata e riflessa che consente di mantenere sulla fovea un’immagine- bersaglio in movimento lento e continuo. elaborata dal sistema extra-genicolo-striato, per permettere al sistema genicolo striato l’osservazione foveale dell’immagine stessa. Smooth pursuit, Maintains gaze stabilization when rate of eye movement is. < 60d/sec, i.e.

Isotalo E(1), Pyykkö I, Juhola M, Aalto H. Author information: (1)Department of Otolaryngology, University of Helsinki, Finland. We examined the pseudo random smooth pursuit test in patients with cerebellopontine angle (CPA) tumors. 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). If so, the fixation suppression test is redundant because the pursuit function is tested in two other tests within the ENG test battery: the tracking and optokinetic tests.

Objective: 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 of dizziness. Smooth pursuit eye movements (SPEMs) and saccadic eye movements are both commonly impaired following sport-related concussion (SRC). Typical oculomotor assessments measure individual eye movements in a series of restrictive tests designed to isolate features such as response times.

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. It has also been suggested that malingering and symptom amplification for financial gain could underlie such symptoms in some cases of WAD (14,15).Recently Tjell & Rosenhall (7) reported on a method (the Smooth Pursuit Neck Torsion Test (SPNT)), which is thought to test the proprioceptive reflexes of the neck, the cervico-collic reflex (CCR) and the cervico-ocular reflex (COR). tude. These results show that the response of the smooth-pursuit subsystem to target motion above 0.5 Hz is poor, even though the velocity and the acceleration of th motions are low. Models of smooth pursuit in which the re-sponse of the eye depends exclusively on the velocity, acceleration, or position of the target do not account for our results.

EOG recordings of smooth pursuit tests with 0.3, 0.4, 0.5 and 15 Hz amplitude and gain calculation were preformed.
