Balance Studies
Recent studies indicate the second most common complaint (after lower back pain) heard in the doctor’s office today is dizziness. Isolating the underlying causes for vertigo requires appropriate testing in order to determine whether the patient has a vestibular or non-vestibular disorder.
In a continuing effort to provide our doctors with the cutting edge technology they’ve come to expect from TLC Diagnostics, we now offer a line of innovative products designed to accurately quantify the extent of balance disruption using the latest techniques in DVA (dynamic visual acuity) and OAE (otoacoustic emissions) testing.
DYNAMIC VISUAL ACUITY (DVA) TESTING
VORTEQ™ — provides the unique testing necessary to accurately measure
a patient’s VOR (Vestibular Ocular Reflex) during normal active head movements through DVA (Dynamic Visual Acuity) testing. The VOR serves to stabilize the gaze during head movements by generating equal and opposite compensatory eye movements.
Vorteq™ testing allows for a comprehensive evaluation of the balance disorder patient.
Patients simply shake their head “yes” (vertical VOR test) or “no” (horizontal VOR test) to the beat of an electronic metronome over a frequency range specified for that test.?
Improvements during vestibular rehabilitation therapy can be serially documented to ascertain the amount of vestibular compensation.?
Offers clinicians a simple method to evaluate VOR gain, phase and symmetry.
REALEYES XDVR™ VIDEO GOGGLES — monocular and binocular video goggles are the ideal choice for eye movement observation and recording during canalith repositioning maneuvers for BPPV (Benign Paroxysmal Positional Vertigo) therapy. Leading edge technology combined with miniature infrared sensitive cameras produce exceptional image clarity.
What’s included:
RealEyes™ digital monocular camera—compatible with any laptop PC running on Windows XP!
RealEyesXDVR™ digital video software—allows you to input patient demographics,
complete nystagmus testing protocols and digitally record eye movement videos.
RealEyes XDVR™ USB footswitch—a proprietary microcontroller in the footswitch
provides system security when moving from test to test.
OTOACOUSTIC EMISSIONS (OAE'S) TESTING
Otoacoustic emissions are sounds produced by the cochlea (outer hair cells) and can be measured in the ear canal. These oae’s only occur in a normal coclea with normal hearing sensitivity.
TLC'S ERO-SCAN™is considered the most effective otoacoustic emissions testing device on the market today. Ero-Scan™ provides objective information about hearing and middle ear status with one completely non-invasive test.
Appropriate for adults, children and newborns
Complete diagnostic results of both ears in less than one minute
Results displayed as PASS or REFER
Test is completely objective…no response from patient is necessary – easy testing of non-cooperative or non-English speaking patients.
Printed results appear immediately when unit is replaced in cradle.
Optional database software allows for proper data management through printed color reports
Integrate with HiTRACK, OZ or Microsoft® programs for required state reporting.
THE ERO-SCAN™ DIFFERENCE:
• Accuracy – Patented noise algorithm allows for reliable testing in up to 70 dB of background noise, which means fewer false REFER results
• Portability – Ero-Scan™ hand-held unit runs on batteries, allowing you to move from room to room if necessary.
• Remote probe also makes it easy to maneuver around head of patient to attain a tight ear seal.
• Memory – Ero-Scan™ contains memory to store complete tests for 50 ears.
• Minimal disposable costs – The only costs include eartips (ranging from $.15 to $1.00 per tip.)
