Inversion Test and Sitting-Up Oculomotor Patterns in Patients with Graviceptive Heavy Posterior Cupula - A Case Series.

A graviceptive heavy posterior cupula typically results from cupulolithiasis and clinically manifests as short vertigo spells when the head moves in the provocative position. Half-Hallpike test (HHT) in posterior cupulolithiasis (PSC-BPPV-) elicits an upbeating ipsitorsional nystagmus (UBITN), which lasts more than a minute as per the consensus criteria developed by the Barany Society. In the last decade, cases with canalolithiasis in the short arm of the posterior semicircular canal (PSC-BPPV-), wherein the otoconial debris falls on the utricular side of the posterior cupula on getting up from supine, rendering it heavy (graviceptive), have been reported.

Vestibular Rehabilitation of the Persons affected by Benign Paroxysmal Positional Vertigo (BPPV) by Physical Therapy and Repositioning Maneuvers.

Vestibular rehabilitation therapy (VRT) mainly comprises physical therapies that encourage head, eye, and truncal movements, accelerating the recovery of patients with acute peripheral labyrinthine dysfunction. VRT aims to improve vestibular hypofunction by reinforcing vestibulo-ocular, vestibulospinal, and vestibulocollic reflexes. An asymmetry in peripheral vestibular inputs from the pair of membranous labyrinths to the central nervous system frequently results from vestibular lithiasis, causing benign paroxysmal positional vertigo (BPPV).

A case of apogeotropic horizontal canal benign paroxysmal positional vertigo that transformed to the geotropic variant during treatment with Appiani maneuver, followed by successful treatment with Gufoni maneuver.

Lesions at three possible sites can masquerade as apogeotropic horizontal semicircular canal benign paroxysmal positional vertigo (HSC-BPPV), namely: 1) short anterior (ampullary) arm canalolithiasis; and 2) culpulolithiasis, which may be either canal (Cup-C) or utricle-sided (Cup-U). There are no clinical methods or investigations to determine the exact pathological site when a patient with a history compatible with HSC-BPPV is found to have apogeotropic positional nystagmus on the supine roll test. Therefore, the treatment of apogeotropic variant of HSC-BPPV not only poses difficulties but the therapeutic options need to be tailored according to the ostensible localization of the pathology.
