The re-positioning chair Rotundum R1 is
designed for research and therapeutic treatment of
patients with Benign Paroxysmal Positional Vertigo
(BPPV).



It is used to perform the re-positioning manoeuvres
to relocate the dislodged calcium crystals (otoconia
or otoliths) in the inner ear of the patient.

The re-positioning chair can be used in combination with
suitable systems for the diagnostic and therapeutic
treatment.
Rotundum R1 is the result of a close collaboration
between the University Hospital of Zürich, the Swiss
Concussion Center, and the Swiss Engineering
Company prolim engineering
