The active head-impulse test in unilateral peripheral vestibulopathy.
BACKGROUND The head-impulse test, which is sensitive and specific for detecting severe unilateral peripheral vestibulopathy, is an accepted part of the neurological examination, especially in patients with vertigo and balance disorders. OBJECTIVE To discover if the head-impulse test is just as useful diagnostically when patients are asked to rotate their own heads, the active head-impulse tes...
متن کاملThe video head impulse test: diagnostic accuracy in peripheral vestibulopathy.
BACKGROUND The head impulse test (HIT) is a useful bedside test to identify peripheral vestibular deficits. However, such a deficit of the vestibulo-ocular reflex (VOR) may not be diagnosed because corrective saccades cannot always be detected by simple observation. The scleral search coil technique is the gold standard for HIT measurements, but it is not practical for routine testing or for ac...
متن کاملCerebellar haemorrhage mimicking acute peripheral vestibulopathy: the role of the video head impulse test in differential diagnosis
Dizziness and vertigo without neurological signs are typically due to a peripheral vestibular disease. Although the most common causes are benign, differential diagnosis must include potentially life-threatening central diseases such as cerebrovascular pathologies. A systemic clinical approach needs a careful work-up, bedside examination and appropriate instrumental investigation. The head impu...
متن کاملAbnormal Head Impulse Test in a Unilateral Cerebellar Lesion
BACKGROUND The findings of head impulse tests (HIT) are usually normal in cerebellar lesions. CASE REPORT A 46-year-old male presented with progressive dizziness and imbalance of 3 weeks duration. The patient exhibited catch-up saccades during bedside horizontal HIT to either side, which was more evident during the rightward HIT. However, results of bithermal caloric tests and rotatory chair ...
متن کاملThe video head impulse test.
CONCLUSION Additional research is needed to validate the importance of the video head impulse tests (vHIT), but it provides an important contribution to the evaluation of anterior and posterior semicircular canal disorders. OBJECTIVES To share observations of the vHIT test in clinical neurotology and to discuss the significance of the study findings. METHODS This study comprised 200 patient...
