ROTUNDUM rotary chair
Rotundum is a manual rotary chair for the diagnosis and therapy of benign paroxysmal positional vertigo (BPPV). Thanks to its continuously adjustable axes, patients can be moved into any desired position effortlessly and in complete safety. With Rotundum, maximum precision allows systematic and reproducible diagnosis and treatment of BPPV. And most importantly: sophisticated technology caters to every requirement in research as well as in clinical practice.
The advantages of ROTUNDUM at a glance:
All conceivable manoeuvres in BPPV diagnosis and therapy can be performed safely and precisely
Effortless, ergonomic work regardless of the patient’s body weight
Systematic and reproducible work
-
Ergonomic operation regardless of the patient’s body weight.
Rotundum is perfectly balanced thanks to a patented mechanism, i.e. adjusted for any body weight. The patient’s body weight is intelligently utilised as a counterweight.
Safety and control at all times during all manoeuvres.
Rotundum cannot move without intentionally applying the axis brakes. This makes it impossible to rotate without an operator.
Reproducible and systematic work thanks to high-precision angle adjustment.
Yaw, roll and pitch axes are equipped with high-resolution degree scales for very high-precision angle adjustment.
Fast immobilisation of the patient.
Our experience shows that with a little practice, patients can be safely immobilised in three minutes.

How ROTUNDUM works.
QUOTE
‘Since being deployed in 2019, the Rotundum has become indispensable for diagnosing and treating benign paroxysmal positional vertigo at the Baden Cantonal Hospital. Thanks to the en bloc positioning and precise alignment of the patient, as well as the wide selection of manoeuvres, we can now provide patients with pre-existing conditions such as cervical spine pathology with suitable diagnostics and therapy. At the same time, the Rotundum has been continuously developed by the balcare engineers who pay particular attention to user feedback and suggestions for improvement.’

Chief Physician, Neurology, Cantonal Hospital Baden
VIDEO GOGGLES
We also offer various video goggles (Video Frenzel, VNG systems) for the ROTUNDUM rotary chair. The combination of Rotundum and video goggles has now become a must-have in vestibular diagnostics and therapy
How the combination of ROTUNDUM and video goggles works:
Video Frenzel VNG goggles – ICS Impulse
The advantages of ICS IMPULSE at a glance.
Extremely lightweight and comfortable to wear video goggles.
One pair of goggles for 5 possible modules – individually adaptable 5-in-1 option for vestibular diagnostics.
ICS Impulse can be ideally combined with the Rotundum rotary chair.
The diagnosis of vestibular disorders can be time-consuming and difficult. ICS Impulse, the customisable solution for balance diagnostics, offers different options to help your patients faster and better.
All features of ICS Impulse have been developed to integrate perfectly into your normal workflow, thus supporting it optimally. With the innovative visual block solution, you can prevent fixation suppression and record data with visual block. The external monitor allows better observation of the patient’s reactions – particularly during positioning tests and position change manoeuvres. A remote control allows you to stay close to the patient throughout the data recording process.
-
At the heart of ICS Impulse are the high-performance Video Frenzel goggles, which allow you to examine and treat vestibular disorders cost-effectively and quickly.
-
The globally leading solution for examining all six semicircular canals using head impulse testing.
-
Achieve even greater accuracy in the examination and treatment of BPPV patients. This is possible thanks to head position and head velocity feedback, 3D nystagmus assessment and real-time SPV.
-
This new approach to performing oculomotor tests allows you to differentiate between central and peripheral disorders quickly and easily.
-
Assesses the lateral semicircular canal function with head position feedback, 3D nystagmus assessment and an external monitor with superior playback function.
Video Frenzel VNG goggles – VertiGoggles
The advantages of VertiGoggles at a glance.
Extremely lightweight video goggles.
The accompanying VertiPACS software offers a variety of individually selectable modules for vestibular diagnostics.
VertiGoggles can be ideally combined with the Rotundum rotary chai
VertiGoggles are a state-of-the-art infrared goggle system for simultaneous recording of eye and head movements in daylight and in the dark. They are configurable in frame rate (up to 220 fps) and resolution (up to Full HD) and are thus suitable for performing head impulse testing as well as all VNG tests. At just 118 g, the goggles are very light and comfortable to wear. They allow either the left or the right eye to be recorded. Due to the special elastic design, they are also suitable for examining children. A simple magnetically held cover allows examination in complete darkness, and an integrated, program-controlled LED offers a fixation target.
-
The symmetrical design of the monocular video goggles allows testing of the left and/or right eye. The goggles weigh 118 g, have a frame rate of up to 220 fps and a built-in gyro sensor. They can be darkened using the magnetic cover.

Case history
This feature allows the systematic recording of a patient’s case history of vertigo. The case history function allows the delegation and documentation of the vertigo case history.Clinical findings
Information on ear findings, vestibulospinal tests, visual tests, blood tests and other tests can be entered here. The main findings and optional further findings complete the clinical picture.Image capture
Images generated in the course of vertigo diagnostics, photos of otoscopic examinations of the tympanic membrane, ophthalmoscopic images of the ocular fundus or, for example, X-rays and documents available digitally can be consolidated here. These images can be stored in the patient database and printed out as part of the report.Dizziness Handicap Inventory
When this familiar questionnaire is used with VertiPACS®, the program calculates the score and subscores and generates a result immediately. This test can be performed independently by patients with VertiQuest®. -
Calibration
This test is used to calibrate the video goggles. The distance between the eye and the mirror of the goggles is calibrated.Direction of gaze test
This test is used to document the direction of gaze-dependent spontaneous nystagmus and calculates its direction and strength automatically.Position test
This test is used to document position-dependent nystagmus, which often occurs in patients with atypical positional vertigo or central disorders.Positional test
This test is to diagnose typical positional vertigo. It can also be used to document repositioning manoeuvres in BPPV therapy.Caloric test
The classic test of the labyrinth. In addition to visualising spontaneous nystagmus, the results of the irrigation are shown in typical culmination diagrams and Freyss diagrams, thus allowing diagnosis at a glance. Values of the lateral difference, directional predominance and fixation index are calculated automatically and displayed in tabular form.User-defined test
This feature allows users to freely configure their own VNG tests, which can be used separately or in conjunction with other tests as part of a test procedure. -
Calibration
This test is used to calibrate the video goggles. The distance between the eye and the mirror of the goggles is calibrated.HIMP
The head impulse test (HIMP) allows a side-dependent evaluation of all semicircular canals. The eye tracking can be shown superimposed on the head movement or mirrored in the test result. It is also possible to mirror the diagram for the left ear. The playback function allows simultaneous playback of the eye video and the measurement curves in the location and speed domain.SHIMP
SHIMP (Suppression Head Impulse Test) is a new variant of the head impulse test. This test allows you to see whether and to what extent there is still residual function on the affected side. During the test, the patient stares at a built-in LED in the VertiGoggles video goggles as a fixation target in order to suppress the vestibulo-ocular reflex. The completely light-excluding and magnetically held eye cover facilitates the test. -
Torsion
The diagnosis of peripheral and central disorders requires the systematic examination of the eye movements. For an assessment, it is necessary to detect horizontal, vertical and torsional eye movements.The registration of torsional eye movements is performed in the following tests:
» Direction of gaze
» Position test
» Positional test
» Individual test -
Optokinetics
Disorders caused by a malfunction of the optokinetic system can be detected with this test. The test allows examination of the optokinetic system with different horizontal and vertical stimuli at three speeds.Smooth gaze sequence
Disorders caused by a malfunction of the gaze-following system can be detected with this test. It allows examination of the gaze-following system with horizontal and vertical stimuli at four speeds. The horizontal and vertical stimuli have a fixed amplitude of ±15° (horizontal) and ±10° (vertical).Conventional saccades
The test assesses the saccade system with horizontal and vertical stimuli. The amplitude of the stimulus is between ±5° and ±30°. It alternates in direction and is equal in number. Speed, precision and latency are assessed and the number of attempts, missed saccades, valid saccades and express saccades are determined.Gaze-holding function
This test is used to detect gaze direction-dependent nystagmus. The measurement duration, as well as the step duration and step amplitude horizontally and vertically, can be set in the test settings.
QUOTE
‘Thanks to the Rotundum, we’ve been able to achieve a considerable improvement in the diagnosis and therapy of benign paroxysmal positional vertigo in our clinic. The positioning with simultaneous video oculography allows us to detect considerably more cases, and for quite a few patients, it’s only with the Rotundum that efficient relief becomes possible.’
