2 Clinical Trial Clinical use of electrode differentiation to enhance programming of cochlear implants. 2013

Saleh, Shaza M / Saeed, Shakeel R / Meerton, Leah / Moore, David R / Vickers, Deborah A. · ·Cochlear Implants Int · Pubmed #24533757.

ABSTRACT: The effect of deactivating indiscriminable cochlear implant (CI) electrodes for unilaterally implanted adults was evaluated using the BKB (Bamford-Kowal-Bench) sentence test in quiet and in pink noise (signal-to-noise ratio of +10dBA) and the adaptive Coordinate Response Measure (CRM). Each CI recipient who failed electrode differentiation (ED) in at least one electrode-pair, based on results of a pure-tone pitch-ranking task received two research programmes to try out in a cross-over study. Research programmes (RP) either employed discriminable electrodes only or the most discriminable two-thirds of the electrodes in the electrode array for CI recipients failing ED for more than a third of the electrodes. The participants were also asked to subjectively report improvement of or decline in sound quality in everyday listening situations. There was significant improvement in CRM speech reception thresholds (SRTs) (Z = -3.24, N = 15, P = 0.001), BKB sentence scores in quiet (t = 3.17, df = 24, P < 0.005) and also in pink noise (t = 2.26, df = 19, P < 0.005) after deactivating indiscriminable electrodes.

3 Article Comparison of Different Hearing Aid Prescriptions for Children. 2018

Marriage, Josephine E / Vickers, Deborah A / Baer, Thomas / Glasberg, Brian R / Moore, Brian C J. ·Department of Paediatric Audiology, Chear, Shepreth, Royston, Herts, United Kingdom. ·Ear Hear · Pubmed #28691934.

ABSTRACT: OBJECTIVES: To assess whether there are significant differences between speech scores for different hearing aid prescription methods, specifically DSL i/o, DSL V, and NAL-NL1, using age-appropriate closed- and open-set speech tests with young children, designed to avoid floor and ceiling effects. DESIGN: Participants were 44 children with moderate or severe bilateral hearing loss, 8 aged 2 to 3 years, 15 aged 4 to 5 years, and 21 aged 6 to 9 years. Children wore bilateral hearing aids fitted with each prescription method in turn in a balanced double-blind design. The speech tests used with each child (and for some tests the levels) were chosen so as to avoid floor and ceiling effects. For the closed-set tests, the level used was selected for each child based on their hearing loss. The tests used were: (1) The closed-set Consonant Confusion Test of word identification; (2) The closed-set Chear Auditory Perception Test (CAPT) of word identification. This has separate sections assessing discrimination of consonants and vowels and detection of consonants; (3) The open-set Cambridge Auditory Word Lists for testing word identification at levels of 50 and 65 dBA, utilizing 10 consonant-vowel-consonant real words that are likely to be familiar to children aged 3 years or older; (4) The open-set Common Phrases Test to measure the speech reception threshold in quiet; (5) Measurement of the levels required for identification of the Ling 5 sounds, using a recording of the sounds made at the University of Western Ontario. RESULTS: Scores for the Consonant Confusion Test and CAPT consonant discrimination and consonant detection were lower for the NAL-NL1 prescription than for the DSL prescriptions. Scores for the CAPT vowel-in-noise discrimination test were higher for DSL V than for either of the other prescriptions. Scores for the Cambridge Auditory Word Lists did not differ across prescriptions for the level of 65 dBA, but were lower for the NAL-NL1 prescription than for either of the DSL prescriptions for the level of 50 dBA. The speech reception threshold measured using the Common Phrases Test and the levels required for identification of the Ling 5 sounds were higher (worse) for the NAL-NL1 prescription than for the DSL prescriptions. CONCLUSIONS: The higher gains prescribed by the DSL i/o and DSL V prescription methods relative to NAL-NL1 led to significantly better detection and discrimination of low-level speech sounds.

4 Article Role of Cortical Auditory Evoked Potentials in Reducing the Age at Hearing Aid Fitting in Children With Hearing Loss Identified by Newborn Hearing Screening. 2017

Mehta, Kinjal / Watkin, Peter / Baldwin, Margaret / Marriage, Josephine / Mahon, Merle / Vickers, Deborah. ·1 Ear Institute, 4919 University College London , UK. · 2 Department of Audiology, 156708 Whipps Cross University Hospital , London, UK. · 3 Chears Ltd, Royston, UK. · 4 Psychology and Language Sciences, 4919 University College London , UK. ·Trends Hear · Pubmed #29205100.

ABSTRACT: Recording of free-field cortical auditory evoked potential (CAEP) responses to speech tokens was introduced into the audiology management for infants with a permanent childhood hearing impairment (PCHI) during 2011-2015 at a U.K. service. Children with bilateral PCHI were studied from two sequential cohorts. Thirty-four children had followed an audiology pathway prior to CAEP introduction, and 44 children followed a pathway after the introduction of CAEP and were tested with unaided and aided CAEP responses. Data analysis explored the age of diagnosis, hearing aid fitting, and referral for cochlear implant (CI) assessment for each of these groups. CAEP offered a novel educative process for the parents and audiologists supporting decision-making for hearing aid fitting and CI referral. Delays in hearing aid fitting and CI referral were categorized as being due to the audiologist's recommendation or parental choice. Results showed that the median age of hearing aid fitting prior to CAEP introduction was 9.2 months. After the inclusion of CAEP recording in the infant pathways, it was 3.9 months. This reduction was attributable to earlier fitting of hearing aids for children with mild and moderate hearing losses, for which the median age fell from 19 to 5 months. Children with profound hearing loss were referred for CI assessment at a significantly earlier age following the introduction of CAEP. Although there has also been a national trend for earlier hearing aid fitting in children, the current study demonstrates that the inclusion of CAEP recording in the pathway facilitated earlier hearing aid fitting for milder impairments.

ABSTRACT: The spatial auditory change complex (ACC) is a cortical response elicited by a change in place of stimulation. There is growing evidence that it provides a useful objective measure of electrode discrimination in cochlear implant (CI) users. To date, the spatial ACC has only been measured in relatively experienced CI users with one type of device. Early assessment of electrode discrimination could allow auditory stimulation to be optimized during a potentially sensitive period of auditory rehabilitation. In this study we used a direct stimulation paradigm to measure the spatial ACC in both pre- and post-lingually deafened adults. We show that it is feasible to measure the spatial ACC in different CI devices and as early as 1 week after CI switch-on. The spatial ACC has a strong relationship with performance on a behavioural discrimination task and in some cases provides information over and above behavioural testing. We suggest that it may be useful to measure the spatial ACC to guide auditory rehabilitation and improve hearing performance in CI users.

6 Article Hearing Characteristics of Stroke Patients: Prevalence and Characteristics of Hearing Impairment and Auditory Processing Disorders in Stroke Patients. 2017

Koohi, Nehzat / Vickers, Deborah A / Lakshmanan, Rahul / Chandrashekar, Hoskote / Werring, David J / Warren, Jason D / Bamiou, Doris-Eva. ·National Hospital for Neurology and Neurosurgery, London, UK. · UCL Ear Institute, University College London, London, UK. · The Institute of Neurology, University College London, London, UK. ·J Am Acad Audiol · Pubmed #28590894.

ABSTRACT: BACKGROUND: Stroke survivors may suffer from a range of hearing impairments that may restrict their participation in postacute rehabilitation programs. Hearing impairment may have a significant impact on listening, linguistic skills, and overall communication of the affected stroke patient. However, no studies sought to systematically characterize auditory function of stroke patients in detail, to establish the different types of hearing impairments in this cohort of patients. Such information would be clinically useful in understanding and addressing the hearing needs of stroke survivors. PURPOSE: The present study aimed to characterize and classify the hearing impairments, using a detailed audiological assessment test battery, in order to determine the level of clinical need and inform appropriate rehabilitation for this patient population. RESEARCH DESIGN: A case-control study. STUDY SAMPLE: Forty-two recruited stroke patients who were discharged from a stroke unit and 40 control participants matched for age. DATA COLLECTION AND ANALYSIS: All participants underwent pure-tone audiometry and immittance measurements including acoustic reflex threshold, transient-evoked otoacoustic emissions, auditory-evoked brainstem response, and a central auditory processing assessment battery, performed in a single session. Hearing impairments were classified as peripheral hearing loss (cochlear and neural type), central auditory processing disorder (CAPD), and as a combination of CAPD and peripheral hearing loss. RESULTS: Overall mean hearing thresholds were not significantly different between the control and stroke groups. The most common type of hearing impairment in stroke patients was the combination type, "peripheral and CAPD," in the 61- to 80-yr-old subgroup (in 55%), and auditory processing deficits in 18- to 60-yr-olds (in 40%), which were both significantly higher than in controls. CONCLUSIONS: This is the first study to examine hearing function in detail in stroke patients. Given the importance of hearing for the efficiency of communication, it is essential to identify hearing impairments and differentiate peripheral and central deficits to define an appropriate intervention plan.

7 Article Assessment and Outcome in Non-Traditional Cochlear Implant Candidates. 2016

Heywood, Rebecca L / Vickers, Deborah A / Pinto, Francesca / Fereos, George / Shaida, Azhar. ·Royal National Throat, Nose and Ear Hospital, London, UK. ·Audiol Neurootol · Pubmed #28222437.

ABSTRACT: The objectives of this study were to assess: (i) patient expectations met as a measure of outcome in early-deafened, late-implanted (non-traditional) cochlear implant recipients and (ii) pre-implantation predictive factors for postoperative speech perception. The notes of 13 recipients were retrospectively reviewed. The mean age at onset of profound deafness was 1.5 years (range 0-6). The mean age at implantation was 37 years (range 22-51 years). Patient expectations were assessed pre-operatively and 1 year after implantation. They were met or exceeded in 129/140 (92%) domains overall. A higher Speech Intelligibility Rating and audiovisual City University of New York sentence score before implantation were found to be positive predictive factors for improved speech discrimination after cochlear implantation.

ABSTRACT: BACKGROUND: Adult cochlear implant (CI) candidacy is assessed in part by the use of speech perception measures. In the United Kingdom the current cut-off point to fall within the CI candidacy range is a score of less than 50% on the BKB sentences presented in quiet (presented at 70 dBSPL). GOAL: The specific goal of this article was to review the benefit of adding the AB word test to the assessment test battery for candidacy. RESULTS: The AB word test scores showed good sensitivity and specificity when calculated based on both word and phoneme scores. The word score equivalent for 50% correct on the BKB sentences was 18.5% and it was 34.5% when the phoneme score was calculated; these scores are in line with those used in centres in Wales (15% AB word score). CONCLUSION: The goal of the British Cochlear Implant Group (BCIG) service evaluation was to determine if the pre-implant assessment measures are appropriate and set at the correct level for determining candidacy, the future analyses will determine whether the speech perception cut-off point for candidacy should be adjusted and whether other more challenging measures should be used in the candidacy evaluation.

ABSTRACT: INTRODUCTION: The National Institute of Health and Care Excellence (NICE) has derived candidacy guidelines for cochlear implants in the UK based on audiometric thresholds (90 dB HL or above at 2 and 4 kHz; hereafter referred to as the 90 dB HL criteria). Recent research has proposed that these criteria should be changed to 80 dB HL at 2 and 4 kHz (hereafter referred to as the 80 dB HL criteria) in the ear to be implanted. METHODS: In this study, we analysed aided SII scores derived for different hearing loss profiles falling within the current 90 dB HL criteria and equivalent profiles falling within the new 80 dB HL criteria. RESULTS: The aided SII scores demonstrated that the majority of potential hearing configurations falling within the new proposed 80 dB HL criteria have aided SII values of less than 0.65 (a recommended cut-off point below which there is not sufficient audibility to receive adequate benefit through hearing aids). CONCLUSIONS: This supports the proposed change to the 80 dB HL criterion level and also highlights the additional value of the SII score in supporting candidacy decisions for CI, especially for borderline candidates.

10 Article Developing an assessment approach for perceptual changes to tinnitus sound characteristics for adult cochlear implant recipients. 2015

Greenberg, David / Meerton, Leah / Graham, John / Vickers, Deborah. ·a UCL Ear Institute , London , UK and. · b Royal National Throat , Nose & Ear Hospital , London , UK. ·Int J Audiol · Pubmed #27146518.

ABSTRACT: OBJECTIVE: To investigate the impact of cochlear implantation on tinnitus suppression, characteristics, localization, and duration. DESIGN: A cochlear implant (CI) recipient-focused postal questionnaire survey. STUDY SAMPLE: The questionnaire was posted, with consent, to 100 adults who had received a unilateral CI at the RNTNEH between 1988 and 1999. All adults spoke English as their first language and were postlingually deafened. Sixty-eight adults (38 female, 29 male, one unspecified) aged 31-80 years (mean 61 years) completed and returned the questionnaire without interview. RESULTS: With the processor 'ON', CI recipients experienced total or partial suppression of tinnitus ipsilateral to their CI in 57% of cases, and in 43% where tinnitus was perceived contralateral to the CI. The percentage of CI recipients who experienced high tone tinnitus was reduced from 60% pre-implant to 29% post-implant with the processor 'ON' while pulsatile tinnitus was reduced from 38% pre-implant to 13% post-implant. CIs were also found to reduce the tonal complexity and duration, and change the source localization of tinnitus post-implantation. CONCLUSIONS: Perceptual changes to tinnitus can take place post-implantation. Changes can occur within the four categories explored: tinnitus suppression, characteristics, localization, and duration of awareness per day.

11 Article Simultaneous Assessment of Speech Identification and Spatial Discrimination: A Potential Testing Approach for Bilateral Cochlear Implant Users? 2015

Bizley, Jennifer K / Elliott, Naomi / Wood, Katherine C / Vickers, Deborah A. ·University College London, London, UK j.bizley@ucl.ac.uk. · University College London, London, UK. ·Trends Hear · Pubmed #26721927.

ABSTRACT: With increasing numbers of children and adults receiving bilateral cochlear implants, there is an urgent need for assessment tools that enable testing of binaural hearing abilities. Current test batteries are either limited in scope or are of an impractical duration for routine testing. Here, we report a behavioral test that enables combined testing of speech identification and spatial discrimination in noise. In this task, multitalker babble was presented from all speakers, and pairs of speech tokens were sequentially presented from two adjacent speakers. Listeners were required to identify both words from a closed set of four possibilities and to determine whether the second token was presented to the left or right of the first. In Experiment 1, normal-hearing adult listeners were tested at 15° intervals throughout the frontal hemifield. Listeners showed highest spatial discrimination performance in and around the frontal midline, with a decline at more eccentric locations. In contrast, speech identification abilities were least accurate near the midline and showed an improvement in performance at more lateral locations. In Experiment 2, normal-hearing listeners were assessed using a restricted range of speaker locations designed to match those found in clinical testing environments. Here, speakers were separated by 15° around the midline and 30° at more lateral locations. This resulted in a similar pattern of behavioral results as in Experiment 1. We conclude, this test offers the potential to assess both spatial discrimination and the ability to use spatial information for unmasking in clinical populations.

12 Article Using singing to nurture children's hearing? A pilot study. 2015

Welch, Graham F / Saunders, Jo / Edwards, Sian / Palmer, Zoe / Himonides, Evangelos / Knight, Julian / Mahon, Merle / Griffin, Susanna / Vickers, Deborah A. · ·Cochlear Implants Int · Pubmed #26561889.

ABSTRACT: This article reports a pilot study of the potential benefits of a sustained programme of singing activities on the musical behaviours and hearing acuity of young children with hearing impairment (HI). Twenty-nine children (n=12 HI and n=17 NH) aged between 5 and 7 years from an inner-city primary school in London participated, following appropriate ethical approval. The predominantly classroom-based programme was designed by colleagues from the UCL Institute of Education and UCL Ear Institute in collaboration with a multi-arts charity Creative Futures and delivered by an experienced early years music specialist weekly across two school terms. There was a particular emphasis on building a repertoire of simple songs with actions and allied vocal exploration. Musical learning was also supported by activities that drew on visual imagery for sound and that included simple notation and physical gesture. An overall impact assessment of the pilot programme embraced pre- and post-intervention measures of pitch discrimination, speech perception in noise and singing competency. Subsequent statistical data analyses suggest that the programme had a positive impact on participant children's singing range, particularly (but not only) for HI children with hearing aids, and also in their singing skills. HI children's pitch perception also improved measurably over time. Findings imply that all children, including those with HI, can benefit from regular and sustained access to age-appropriate musical activities.

14 Article Bilateral cochlear implantation for hearing-impaired children: criterion of candidacy derived from an observational study. 2015

Lovett, Rosemary Elizabeth Susan / Vickers, Deborah Anne / Summerfield, Arthur Quentin. ·1Ear Institute, University College London, London, United Kingdom; and 2Department of Psychology and Hull York Medical School, University of York, York, United Kingdom. ·Ear Hear · Pubmed #25170781.

ABSTRACT: OBJECTIVES: Policy-makers have struggled to define the minimum degree of hearing impairment at which children should be offered cochlear implants rather than the less invasive alternative of acoustic hearing aids. This study compared outcomes for children with bilateral cochlear implants and children with bilateral hearing aids, to determine a criterion of candidacy for pediatric bilateral cochlear implantation. DESIGN: This observational study measured the listening skills of children who received routine audiological care in the United Kingdom. Participants were recruited from hospitals, educational services, and charities. Eligibility criteria included a diagnosis of hearing impairment before 31 months of age and pure-tone thresholds greater than or equal to 50 dB HL at 2 and 4 kHz bilaterally. Seventy-one children participated, aged 46 to 86 months (mean 64 months). Twenty-eight children used bilateral implants provided in a simultaneous surgery; 43 used bilateral digital hearing aids. The two groups of children were demographically similar in variables that predict outcomes for children with hearing impairment. Children's ability to understand speech was measured using closed-set tests of word discrimination in three conditions: in quiet, in pink noise, and in two-talker babble. For each listening test, an actuarial method was used to compare the distribution of scores from children with cochlear implants and children with hearing aids. The aim was to calculate the unaided pure-tone average (PTA) hearing level at which a child has odds of 4:1 of a better outcome with implants than with hearing aids. The PTA associated with odds of 4:1 has been used previously to define criteria of candidacy for implantation. The main analyses used a four-frequency PTA (mean of unaided thresholds at 0.5, 1, 2, and 4 kHz in the better-hearing ear). Additional analyses used a three-frequency PTA (0.5, 1, and 2 kHz) and two-frequency PTA (2 and 4 kHz). RESULTS: Odds of 4:1 of a better outcome with implants were associated with a four-frequency PTA of 79, 86, and 76 dB HL for tests of word discrimination in quiet, noise, and babble, respectively. The mean of these three estimates is 80 dB HL. It can be difficult to measure a four-frequency PTA in young children, but a two-frequency PTA typically can be measured. Odds of 4:1 were associated with a two-frequency PTA of 83, 92, and 80 dB HL for tests of word discrimination in quiet, noise, and babble, respectively. The mean of these three estimates is 85 dB HL. CONCLUSIONS: Children with an unaided four-frequency PTA of 80 dB HL or poorer in both ears should be considered candidates for bilateral cochlear implantation. In cases where a four-frequency PTA cannot be measured, the criterion of candidacy should be a two-frequency PTA of 85 dB HL or poorer in both ears. If adopted by policy-makers, these recommendations would expand the provision of cochlear implants among children in England and Wales.

15 Article Test-retest reliability of the Toy Discrimination Test with a masker of noise or babble in children with hearing impairment. 2013

Lovett, Rosemary / Summerfield, Quentin / Vickers, Deborah. ·Ear Institute, University College London, London, UK. r.lovett@ucl.ac.uk ·Int J Audiol · Pubmed #23516964.

ABSTRACT: OBJECTIVE: The Toy Discrimination Test measures children's ability to discriminate spoken words. Previous assessments of reliability tested children with normal hearing or mild hearing impairment, and most studies used a version of the test without a masking sound. We assessed test-retest reliability for children with hearing impairment using maskers of broadband noise and two-talker babble. DESIGN: Stimuli were presented from a loudspeaker. The signal-to-noise ratio (SNR) was varied adaptively to estimate the speech-reception threshold (SRT) corresponding to 70.7% correct performance. Participants completed each masked condition twice. STUDY SAMPLE: Fifty-five children with permanent hearing impairment participated, aged 3.0 to 6.3 years. Thirty-four children used acoustic hearing aids; 21 children used cochlear implants. RESULTS: For the noise masker, the within-subject standard deviation of SRTs was 2.4 dB, and the correlation between first and second SRT was + 0.73. For the babble masker, corresponding values were 2.7 dB and + 0.60. Reliability was similar for children with hearing aids and children with cochlear implants. CONCLUSIONS: The results can inform the interpretation of scores from individual children. If a child completes a condition twice in different listening situations (e.g. aided and unaided), a difference between scores ≥ 7.5 dB would be statistically significant (p <.05).
