In vitro model of a semicircular canal: design and validation of the model and its use for the study of canalithiasis.
نویسندگان
چکیده
We present an experimental model for a semicircular canal with canalithiasis. Canalithiasis is a pathological condition where free-floating particles disturb the flow field in the semicircular canals. It may lead to a specific form of vertigo known as BPPV or top-shelf vertigo. A careful scaling of the physical and geometrical parameters allows us to study the mechanics of this disease on an enlarged model of a single semicircular canal with laser vibrometry and video particle tracking. Early results confirm the proper operation of the model canal and support the current theories on the mechanisms of BPPV.

متن کاملVestibulo-Ocular Reflex Abnormalities in Posterior Semicircular Canal Benign Paroxysmal Positional Vertigo: A Pilot Study
Introduction: Benign paroxysmal positional vertigo (BPPV), involving the semicircular canals, is one of the most common diseases of the inner ear. The video head impulse test (vHIT) is a new test that examines the function of the canals. This study aimed to investigate the vestibulo-ocular reflex (VOR) gain, gain asymmetry and saccades after stimulating all six canals in patients definitively d...

Abstract: The present research aimed at developing and validating a conceptual model for narrowing the gap between intended, implemented, and attained curricula in the public education system in Iran. Two fundamental questions guided this investigation: what model can be developed to reduce the gap between the three mentioned curricula? To what extent does the proposed model gain the approval? ...

متن کاملAfferent responses during experimentally induced semicircular canalithiasis.
Benign paroxysmal positional vertigo (BPPV) is a common vestibular disorder that results in brief periods of vertigo and nystagmus, when the head is tipped relative to gravity. Symptoms are commonly attributed to the pathological presence of heavy calcium carbonate particles within the lumen of the semicircular canal(s)-a condition termed canalithiasis. In the present work, we induced canalithi...
