Available in PDF, EPUB and Kindle. Book excerpt: Introduction: Cortical auditory evoked potentials (CAEP) are a valuable tool for objective threshold estimation in adults as the technique uses highly frequency specific stimuli and can be used with difficult-to-test populations. Current clinical practice uses the four-electrode montage; the midline of the scalp (vertex) is referenced to the mastoid ipsilateral to the ear of stimulation. However, there is considerable evidence for larger cortical responses recorded from the contralateral hemisphere due to contralateral dominance of the ascending auditory pathway, raising the possibility of contralateral hemisphere electrode positioning providing an advantage in clinical CAEP recordings. Aims: The current study investigated whether there would be any differences in N1-P2 response amplitudes or latencies recorded simultaneously from the vertex and contralateral hemisphere, and whether any such differences would translate to clinically significant advantages such as faster test times or improved response detection. A secondary aim was to revisit objective analysis techniques for their utility in the clinical application of CAEPs. Method: CAEPs were measured from 20 normally hearing participants using a two-channel montage on the vertex and contralateral hemisphere, referenced to the ipsilateral mastoid. High (2000 Hz) and low (500 Hz) frequency tonal stimulation at three stimulus levels (20, 30 and 40 dB HL) were presented monaurally. Results: There were no statistically significant differences in N1-P2 amplitude, latency or residual noise measured at the two electrode positions. Residual noises were lower than the applied clinical criterion (1.5 mV), and there was relatively poor correlation between signal-tonoise (SNR) and cross-correlation across all stimulus conditions. Conclusion: Although no contralateral dominance effect could be demonstrated in the current study, the results at least provide an indication that positioning electrodes off the vertex does not degrade test performance. Thus, this allows a certain zone that extends at least as far as the F3 or F4 position in the direction anterior to the vertex where the non-inverting electrode may be placed, providing a practical advantage if, for some reason, conventional midline placement is not feasible. Cross-correlation did not provide a stand-alone indication of response presence or absence, although it can be a useful secondary assessment to support clinical interpretation.

Download or read book Hearing Loss written by National Research Council and published by National Academies Press. This book was released on 2004-12-17 with total page 321 pages. Available in PDF, EPUB and Kindle. Book excerpt: Millions of Americans experience some degree of hearing loss. The Social Security Administration (SSA) operates programs that provide cash disability benefits to people with permanent impairments like hearing loss, if they can show that their impairments meet stringent SSA criteria and their earnings are below an SSA threshold. The National Research Council convened an expert committee at the request of the SSA to study the issues related to disability determination for people with hearing loss. This volume is the product of that study. Hearing Loss: Determining Eligibility for Social Security Benefits reviews current knowledge about hearing loss and its measurement and treatment, and provides an evaluation of the strengths and weaknesses of the current processes and criteria. It recommends changes to strengthen the disability determination process and ensure its reliability and fairness. The book addresses criteria for selection of pure tone and speech tests, guidelines for test administration, testing of hearing in noise, special issues related to testing children, and the difficulty of predicting work capacity from clinical hearing test results. It should be useful to audiologists, otolaryngologists, disability advocates, and others who are concerned with people who have hearing loss.
Download or read book Threshold Estimation in Normal and Impaired Ears Using Auditory Steady State Responses written by Riette Bosman and published by . This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The Auditory Steady State Response (ASSR) procedure has been established as a frequency specific, objective audiologic measure, which can provide reliable thresholds to within 10 dB of the behavioral thresholds. In order for ASSR to find its place in the existing framework of audiometric procedures, the full potential of the procedure needs to be explored. The aim of this study was to determine the accuracy of monotic ASSR in estimating hearing thresholds in a group of 15 normal hearing subjects and 15 hearing-impaired subjects. A comparative research design was implemented. Indicating that results obtained in the study was compared to relevant literature where dichotic multiple ASSR was implemented. This was done in order to ascertain ASSR's capabilities with regard to stimulus presentation methods. Monotic single ASSR predicted behavioural thresholds in the normal hearing subjects within an average of 24 dB across the frequency range (0.5, 1, 2 & 4 kHz). In the hearing-impaired group, ASSR thresholds more closely resembled behavioural thresholds, with an average difference of 18 dB, which is consistent with recent literature. The literature suggests that better prediction of behavioural thresholds will occur with greater degrees of hearing loss, due to recruitment. The focus in this group also centered on the accurate prediction of the configuration of the hearing loss. It was found that ASSR could reasonably accurately predict the configuration of the hearing loss. In the last instance, monotic single and dichotic multiple ASSR were compared with regard to threshold estimation and prediction of configuration of the hearing loss in the hearing-impaired group. Little difference was reported between the two techniques with regard to the estimation of thresholds in both the normal hearing and hearing impaired groups. In conclusion it was established that monotic ASSR could predict behavioural thresholds of varying degrees and configurations of hearing loss in normal and hearing-impaired subjects with a reasonable amount of accuracy. At this stage, however, more research is required to establish the clinical validity of the procedure, before it is routinely included within an objective test battery.

Download or read book Human Auditory Evoked Potentials written by Terence W. Picton and published by Plural Publishing. This book was released on 2010-09-01 with total page 649 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book reviews how we can record the human brain's response to sounds, and how we can use these recordings to assess hearing. These recordings are used in many different clinical situations--the identification of hearing impairment in newborn infants, the detection of tumors on the auditory nerve, the diagnosis of multiple sclerosis. As well they are used to investigate how the brain is able to hear--how we can attend to particular conversations at a cocktail party and ignore others, how we learn to understand the language we are exposed to, why we have difficulty hearing when we grow old. This book is written by a single author with wide experience in all aspects of these recordings. The content is complete in terms of the essentials. The style is clear; equations are absent and figures are multiple. The intent of the book is to make learning enjoyable and meaningful. Allusions are made to fields beyond the ear, and the clinical importance of the phenomena is always considered.
Download or read book Intraoperative Neurophysiologic Monitoring written by Gloria M. Galloway and published by Cambridge University Press. This book was released on 2010-10-28 with total page 257 pages. Available in PDF, EPUB and Kindle. Book excerpt: Intraoperative neurophysiologic monitoring has shown a steady increase in use for surgeries in which neural structures may be at risk of injury. Some of the surgical techniques used carry inherent risks, and these risks have changed the way in which neurophysiologic monitoring has impacted patient safety and quality of care during surgical procedures. It is therefore crucial that those performing and interpreting intraoperative neurophysiologic monitoring are adequately trained. This book is a comprehensive guide to the current practice of intraoperative neurophysiology with chapters on various modalities and clinical uses. Separate chapters devoted to anesthesia, operating room environment, special considerations in pediatrics and the interpretation and reporting of neurophysiologic data are useful and complementary. Questions and detailed answers on the topics covered can be found on the accompanying website for study review. This book will be useful to the trainee as well as the neurophysiologist already in practice.
