SYNAPSYS MED4

The SYNAPSYS MED4 rotary chair completes the battery of video-nystagmographic tests with rotational kinetic exams.
The kinetic tests allow the study of nystagmus induced by angular accelerations applied to the vestibular system, with or without visual reference.

Through SYNAPSYS VNG software, you can control the position of MED4 chair and the amount of energy released to the labyrinth. These examinations then allow the precise calculation of vestibular gain, phase, symmetry and time constants.

ALL KIND OF KINETIC STIMULATIONS

MED4 rotary chair can be used in manual mode or controlled by the SYNAPSYS VNG software, and allows to perform a wide range of kinetic examinations. Sixteen stimulation waveforms are available, including various sine waveforms, multi-frequency, speed step and sudden stop tests.

MAXIMUM COMFORT AND SAFETY FOR THE PATIENT

The MED4 rotary chair can be used for any other vestibular test, including, of course, kinetic tests. The fully reclining backrest allows the patient to be easily positioned at 30° for caloric tests or in a supine position for BPPV treatment maneuvers.

COMPLETES YOUR VESTIBULAR SYSTEM

The MED4 rotary chair, which perfectly integrates with the SYNAPSYS VNG system, is the ideal tool to integrate and complete your balance clinic and examine low and medium frequencies.
