MED4 chair (VNG option)

MED4 chair (VNG option)

Synapsys has designed the MED4 chair for an ENT practice as to complet the VNG tests with the kinetic rotational test

It enables to calculate :
- The vestibular gain
- The phase
- The symmetry
- The time constants
It offers a large range of kinetic tests:
- Various sinusoidal tests (SHA profiles, decreasing sinus
- Multi-frequencies (sweep)
- Multi-turn (step velocity)
- Sudden stop stimulations (square back and forth)

Its ergonomics ensures the patient’s comfort and security when carrying out middle frequencies tests.

DESCRIPTION

The MED4 enables the patient to be in different positions and thus can be used for several vestibular tests complementary to the kinetic test.

OPTIONS

- Safety harness

CONNECTIVITY

The MED4 can be controlled by VNG software or used manually.
