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

High accuracy and reliability in the diagnosis and treatment of BPPV
Rotundum R1 provides roll and yaw, to be able to position the patient anywhere within 360°. The patient is comfortably secured in the seat and integrated scales and brakes ensure precise and repeatable positioning of the patient

Ergonomic design 
Regardless of patients physical stature: all fixations can be adjusted, therefore the patients comfort is guaranteed throughout all possible maneuvers. Comfort is particularly important for physically disabled or elderly patients. With the patient comfortably and securely positioned in the chair, the therapist is able to perform the necessary manoeuvres while maintaining an optimal ergonomic posture. Very little eff ort is required to turn the roll and yaw into the desired position.

Easy to assemble and disassemble
For mobile use, Rotundum R1 folds into itself for compact transport suitable for a panel van or similar sized vehicle. Ideal for providing service to patients in retirement and nursing homes.
