Head-shaking nystagmus
Head-shaking nystagmus. Head-Shaking Nystagmus (HSN) is a latent spontaneous vestibular nystagmus provoked by rapid passive head shaking around a vertical axis. HSN is not specific in distinguishing peripheral hypofunction from more central vestibular imbalances. This test is an excellent bedside test for detecting unilateral vestibular hypofunction but further rotatory and caloric testing will...
متن کامل[Diagnostic value of head-shaking nystagmus in vestibular clinical evaluation].
OBJECTIVES To determine the sensitivity and specificity of the head-shaking nystagmus test (HSN), the nystagmus elicited in response to a vigorous rotation of the head in the horizontal plane, in the study of patients with peripheral unilateral vestibular disease. PATIENTS AND METHODS Retrospectively, we analyze the relationships between the HSN and the rest of the videonystagmographic tests ...
متن کاملHead shaking and vestibulo-ocular reflex in congenital nystagmus.
The authors investigated the mechanisms underlying the head shaking shown by some patients with congenital nystagmus (CN). In order to improve visual function by head shaking, a patient with CN must have some visual acuity loss due to retinal image motion created by the nystagmus; an abnormal vestibulo-ocular reflex (VOR); and the head shaking must be correlated with the nystagmus. The authors ...
متن کامل[Head shaking test (HSN) using to diagnose vestibule damage].
INTRODUCTION There is described a transient nystagmus provoked by shaking the head in the horizontal plane for a few seconds in both normal subjects and patients that is called Head Shaking Test (HSN) as a diagnostic tool for vestibular dysfunction. HSN is generally accepted that is generated by an asymmetrical peripheral vestibular input and a central velocity storage mechanism, which integrat...
متن کاملAbusive head trauma: judicial admissions highlight violent and repetitive shaking.
OBJECTIVE Confessions are uncommon in abusive head trauma (AHT) cases, and there is debate over whether shaking alone can cause the injuries characteristic of AHT. The objective of this article is to correlate legal statements by perpetrators with medical documentation to offer insights into the mechanism of injury. METHODS In this retrospective observational study we examined forensic eviden...
