So assuring to see that BLT and SRT are concordant🎅

Bow-and-Lean Test (BLT): Lean Nystagmus directed to the patient's right and Bow Nystagmus to the patient's left. Supine Roll Test (SRT): elicits Lying-Down N...

Torsional component is subtle in apo-PSC-BPPV, but is important for lateralisation; repositioning manoeuvres in apo-PSC-BPPV are dependent on lateralisation.

Torsional component of downbeating positional nystagmus is very subtle in apogeotropic posterior canal BPPV. (apo-PSC-BPPV). Since the direction of torsional...

Rarest of rare case of combined - Right Horizontal Semicircular Canalolithiasis and Right Posterior semicircular Cupulolithiasis in a patient. Possibly the 2 conditions existed together at the onset. In any positional test the generated nystagmus would be net result of stimulation/inhibition of the 3 semicircular canals. Once the right lateral canalolithiasis was fixed by Gufoni Maneuver the nystagmus of Posterior Cupulolithiasis is unveiled.

A 42-year-old male visited our Otoneurology Centre in the mid-summer of 2023, with 18 days history of rotational vertigo on getting up from supine, and in ei...

Unveiling positional nystagmus in a patient with BPPV, when initial positional tests are unyielding. From "no nystagmus", through diagnostic head-shaking and unveiling of positional nystagmus, therapeutic manoeuvre to "cure" - all in one video. Video is long but highly educational for beginners in Otoneurology. ☺️

Left Horizontal Semicircular Cupulolithiasis (Cup-U variant), that responded to therapeutic head-shaking maneuver (HSM). Videos are long showing prolonged duration apogeotropic positional nystagmus on lateral head roll to either sides (stronger on right), HSM and verifying supine roll test demonstrating the disappearance of apogeotropic positional nystagmus and accompanying vertigo.

Supine Roll Test (Diagnostic): Supine roll test elicits apogeotropic horizontal positional nystagmus on yawing the head maximally to the right and to the lef...
