Normative Data For Neurodiagnostic Auditory Brainstem Response Testing (Abr), David Alan Ness

Doctoral Dissertations

Auditory Brainstem Response (ABR) tests are procedures routinely performed to assess auditory function from the peripheral auditory system to the level of the lower brainstem. The ABR is used as a neurodiagnostic tool to detect retrocochlear pathologies of the auditory system, such as space occupying lesions, tumors, auditory neuropathy, and multiple sclerosis that effect the structures located above the level of the cochlea.

An ABR consists of eliciting and recording waveforms. These waveform recordings elicited are compared to normative data to determine normal versus abnormal (retrocochlear lesion) responses. Generalized normative data is available for ABR test results; however, research states …
