Bio-logic Systems Corp. Navigator Pro Stacked ABR

Standard ABR measures have been used by clinicians as a tool to assist in the assessment of auditory nervous system abnormalities for the past 25 years. Stacked ABR is a modification of standard ABR. It involves collection of data using click stimuli mixed with high-pass masking noise, calculation and alignment of derived band waveforms and calculation of the Stacked ABR. Developed in cooperation with the inventor, Manuel Don, Ph.D. at House Ear Institute1, the stacked auditory brainstem response test procedure displays activity from virtually all auditory nerve fibers rather than just a subset.

Bio-logic Systems Corp. CHAMP

CHAMP was developed in cooperation with the inventor, Manuel Don, Ph.D. at House Ear Institute for the assessment of Meniere's disease/cochlear hydrops. As an option for the Navigator Pro AEP System, CHAMP measures of the Wave V latency change caused by the addition of the high pass masking noise are used in combination with amplitude measures to assess the presence and characteristics of an undermasked response. These data are compared to normative values to assist with analysis.

Bio-logic Systems Corp. VEMP

The Vestibular Evoked Myogenic Potential (VEMP) is a short latency EMG (eletromyographic) response evoked at high level acoustic stimulation and recorded from surface electrodes over the contracted sternocleidomastoid (SCM) muscle. As an option for the Navigator Pro AEP System, VEMP assesses the saccule and inferior vestibular nerve which other tests do not assess. The ability to identify disorders in this area of the vestibular system may improve management of patients with balance disorders. The added diagnostic information can help you design vestibular rehabilitation therapy exercises to more effectively treat patients.

Grason-Stadler Audera

Audera meets your needs for Evoked Potential testing by providing a unique combination of Auditory Steady State Response (ASSR) testing and traditional cochlear and retro-cochlear auditory potentials (ABR, ECochG, AMLR and CAEP). Auditory Steady-State Response (ASSR) is the solution for frequency-specific hearing assessment for people of all ages. Also called the steady-state auditory evoked potential (SSEP), ASSR meets all the criteria for follow-up diagnostic testing. GSI Audera also provides DPOAE testing for hospitals, clinics and offices.

Interacoustics EP15/25

EP15 is a modern 2 channel Evoked Potential system. The EP15 can run automatic test routines for ease of operation, and it comes with common examples already preprogrammed. Stimuli include masking, clicks and tone bursts, allowing frequency specific threshold tests. The included normative data, and the feature of automatic placement of Jewett marks facilitate the diagnostic evaluation. The EP25 is identical to EP15, but additionally allows tests like ECochG, MLR, LLR, P300 and MMN, each with dedicated filters and marking tools etc. Also the EP25 allows connection to Cochlear Implant stimulators for EABR tests. Database A database and integrated report generator is included, and the possibility to send individual sessions by e-mail or any kind of data storage for evaluation elsewhere is a highly practical feature. The extensive display control options like filtering, display gain etc. can all be manipulated after the recording has taken place and may even be handled by any workstation in a network, if the EP15/25 is run within a PC network. Upgrading to OAE The EP15/25 can be upgraded with Interacoustics' TEOAE / DPOAE system. This will make up a fully integrated system for OAE and ABR. In addition to the economical saving due to shared hardware, it allows for very smooth and efficient patient handling, also for those failing a first stage OAE test.
