Sinusoidal Chair Rotation Test

The Swinging Chair Test

Comparisons in Outcome and Subject Comfort between Rotation Chair Systems

BACKGROUND AND OBJECTIVES A rotation chair test has been used to evaluate the function of the horizontal semicircular canals. Currently, two chair systems according to the presence of cylindrical darkroom are used in a clinic setting. However, it has not been thoroughly investigated whether one system is superior to the other system or not. In this study, we aimed to compare test outcomes and s...

Responses of Central Vestibular Neurons to Sinusoidal Yaw Rotation

24 After vestibular labyrinth injury, behavioral measures of vestibular function partially 25 recover through the process of vestibular compensation. The current study was 26 performed to improve our understanding of the physiology of macaque vestibular 27 nucleus neurons in the compensated state (>6 weeks) after unilateral labyrinthectomy 28 (UL). The responses of neurons to sinusoidal yaw rot...

The Supine Internal Rotation Test

Methods: A consecutive series of 309 patients underwent arthroscopic and/or open knee ligament reconstruction surgery. Seven patients were excluded based on the inability to perform a side-to-side comparison of internal rotation. Tibial internal rotation was assessed bilaterally on 302 patients during examination under anesthesia by a single orthopaedic surgeon measuring tibial tubercle excursi...

Standardization of Rotatory Chair Velocity Step and Sinusoidal Harmonic Acceleration Tests in Adult Population

Objective: To standardize the rotatory chair sinusoidal harmonic acceleration and velocity step tests in adult population. Study Design: Prospective study. Setting: Clinical tertiary care vestibular function test center. Patients: One hundred normal participants (66 male and 34 females without suspected vestibular disorder) evaluated with bithermal binaural caloric and sinusoidal and step-veloc...
