Advanced Rotational Testing
The HORTMANN PDS 12 combined with the intuitive Vestlab software is designed to deliver precise, computer controlled rotational stimuli to the vestibular system. All common rotational and pendular tests can be performed quickly and easily with this advanced system. The Windows-based software also allows you to configure your own tests using variable parameters.
The major clinical advantage of computerized rotational testing is the ability to produce angular accelerations that can be precisely controlled and repeated. Multiple stimuli of varying intensities can be applied to the vestibular system within a relatively short time. These tests allow evaluation of the vestibulo-ocular reflex and the optokinetic neural pathways in a manner that is not duplicated by alternative procedures.
Rotary testing is usually better tolerated than caloric testing and is easier to use with pediatric and geriatric populations. It is useful in monitoring progression of disease, compensation over time and in validating bilateral weakness.
Vestlab software
The Rotary Chair requires the Vestlab software, which is supplied in three versions for use with different configurations of vestibular test equipment. Click here to learn more about the Vestlab software
