VertiChair™: A Smarter Approach to Vestibular Diagnosis, Therapy, and Clinical Efficiency

Vestibular disorders are among the leading causes of dizziness and balance impairment, affecting patients of all ages and placing significant demands on healthcare providers. Accurate diagnosis often requires controlled rotational testing and precise observation of eye movements, while effective treatment—particularly for Benign Paroxysmal Positional Vertigo (BPPV)—depends on consistent repositioning maneuvers.

Traditional examination methods frequently rely on manual operation and clinician experience, which can lead to variability in testing and treatment. As vestibular medicine continues to advance, there is a growing need for intelligent systems that improve precision, standardize procedures, and enhance both clinician and patient experiences.

Developed by ZEHNIT Medical Technology, VertiChair™ is designed to meet these needs by combining advanced motion control, automated positioning, and integrated vestibular assessment into a single comprehensive platform.

A Comprehensive Platform for Vestibular Care

Modern dizziness clinics require more than individual diagnostic devices. They need integrated solutions that support the entire clinical pathway—from evaluation and diagnosis to treatment and follow-up.

VertiChair™ combines rotary chair testing and motorized BPPV repositioning within one system, allowing clinicians to perform multiple procedures without transferring patients between different devices.

This integrated approach not only simplifies clinical workflows but also improves examination efficiency, helping healthcare providers deliver consistent, high-quality vestibular care.

Motorized Precision for Reliable Testing

Accurate vestibular assessment depends on controlled and repeatable movements. Even slight differences in rotation speed or positioning can influence examination results.

VertiChair™ features a fully programmable motorized control system that allows clinicians to precisely adjust:

• Rotation angle

• Rotation speed

• Acceleration and deceleration

• Movement direction

• Examination sequences

Predefined protocols and customizable settings help ensure every examination follows standardized procedures, reducing variability and improving diagnostic consistency.

By replacing manual manipulation with intelligent automation, VertiChair™ enables more reproducible clinical outcomes while reducing operator workload.

Optimizing BPPV Diagnosis and Treatment

BPPV is one of the most common vestibular disorders encountered in clinical practice. Successful treatment relies on accurately identifying the affected semicircular canal and performing appropriate repositioning maneuvers.

VertiChair™ is specifically designed to support these procedures through precise motorized positioning. The system guides patients through controlled movements that help clinicians perform repositioning maneuvers with greater confidence and consistency.

Compared with traditional manual techniques, the automated approach offers several advantages:

• Standardized treatment procedures

• Improved positioning accuracy

• Reduced physical effort for clinicians

• Enhanced patient comfort

• Better workflow efficiency

These benefits are particularly valuable in busy vestibular clinics where consistency and productivity are equally important.

Integrated Eye Movement Analysis

Vestibular diagnosis is most effective when body movement and eye movement can be evaluated together.

When connected with VertiGoggles™, VertiChair™ enables synchronized three-dimensional eye movement recording throughout diagnostic and therapeutic procedures.

Clinicians can observe and analyze:

• Horizontal eye movements

• Vertical eye movements

• Torsional eye movements

• Slow-phase velocity (SPV)

• Vestibulo-ocular reflex responses

This synchronized analysis provides objective clinical data that supports more accurate diagnosis and comprehensive documentation.

The integration of automated chair movement with advanced eye tracking creates a highly efficient vestibular assessment environment suitable for both routine examinations and complex clinical cases.

Designed Around Patient Safety

Patients undergoing vestibular examinations often experience dizziness, nausea, or anxiety during testing. Ensuring their comfort and safety is therefore a key consideration in system design.

VertiChair™ incorporates several ergonomic and safety-focused features, including:

• Adjustable head support

• Secure safety harnesses

• Stable seating structure

• Smooth motorized movements

• Comfortable positioning throughout examinations

These features help minimize unnecessary discomfort while allowing clinicians to conduct examinations safely and effectively.

A secure and comfortable testing environment also encourages better patient cooperation, contributing to more reliable diagnostic results.

Supporting Advanced Vestibular Testing

Beyond BPPV diagnosis and treatment, VertiChair™ supports a variety of sophisticated vestibular function assessments.

The system is capable of performing protocols such as:

• Sinusoidal Harmonic Acceleration (SHA)

• Velocity Step Test (VST)

• Vestibulo-Ocular Reflex (VOR) evaluation

• Visually Enhanced Vestibulo-Ocular Reflex (VVOR)

• Vestibulo-Ocular Reflex Suppression (VORS)

• Additional programmable rotational assessments

These testing capabilities enable clinicians to investigate vestibular disorders in greater detail while supporting research and specialized clinical applications.

For hospitals, academic institutions, and dedicated balance centers, VertiChair™ provides the flexibility needed for comprehensive vestibular evaluation.

Seamless Integration Across the ZEHNIT Ecosystem

Healthcare technology is increasingly moving toward integrated platforms rather than isolated devices.

VertiChair™ works seamlessly with other ZEHNIT solutions, including:

• VertiGoggles™ for infrared eye movement recording

• VertiPACS™ for centralized patient management and reporting

• VertiAI™ for AI-assisted vestibular analysis

• VertiPlatform™ for computerized posturography

• VertiSVV™ for subjective visual vertical testing

• VertiRehab™ for vestibular rehabilitation

Together, these systems create a connected ecosystem that supports standardized workflows, efficient data management, and comprehensive patient care from diagnosis through rehabilitation.

Improving Clinical Productivity

Healthcare providers are continually looking for ways to improve efficiency without compromising diagnostic quality.

VertiChair™ contributes to this goal by:

• Reducing manual repositioning time

• Simplifying complex examination procedures

• Standardizing testing protocols

• Improving examination repeatability

• Enhancing documentation through integrated software

These operational benefits allow clinicians to evaluate more patients while maintaining high standards of accuracy and consistency.

Preparing Clinics for the Future of Vestibular Medicine

Vestibular care is becoming increasingly technology-driven, with greater emphasis on automation, digital integration, and objective clinical measurement.

VertiChair™ reflects this evolution by combining intelligent motion control, advanced vestibular testing, and seamless software connectivity into a single platform.

Its innovative design helps healthcare providers adapt to changing clinical demands while supporting evidence-based diagnosis and treatment for patients with dizziness and balance disorders.

Conclusion

VertiChair™ is more than a motorized examination chair—it is a comprehensive vestibular diagnosis and treatment solution designed for modern clinical practice.

By integrating automated positioning, advanced rotational testing, synchronized eye movement analysis, and digital workflow management, it enables clinicians to deliver more precise, efficient, and standardized vestibular care.

As balance medicine continues to evolve, VertiChair™ provides healthcare professionals with the technology needed to improve diagnostic confidence, optimize treatment outcomes, and enhance the overall patient experience.
