Teledelivery of Aural Rehabilitation to Improve Cochlear Implant Outcomes.

OBJECTIVE(S): This randomized controlled study evaluated the effectiveness of a Telehealth Aural Rehabilitation (TeleAR) training protocol to improve outcomes for adult cochlear implant (CI) users. METHODS: This was a multisite clinical study with participants randomized to either an AR treatment or active control group. The AR protocol consisted of auditory training (words, sentences, and speech tracking), informational counseling, and communication strategies. The control group participants engaged in cognitive stimulation activities (crosswords, sudoku, etc.). Each group completed 6 weekly 90-min individual treatment sessions delivered remotely. Twenty postlingually deafened adult CI users participated. Assessments were completed pretreatment and 1 week and 2 months posttreatment. RESULTS: Repeated-measures ANOVA and planned contrasts were used to compare group performance on AzBio Sentences, Hearing Handicap Inventory (HHI), Client Oriented Scale of Improvement (COSI), and Glasgow Benefit Inventory (GBI). The two groups were statistically equivalent on all outcome measures at pre-assessment. There was a statistically significant main effect of time for all measures. Improvement over time was observed for participants in both groups, with greater improvement seen for the AR than the CT group on all outcome measures. The AR group showed medium to large effect sizes on all measures over time, suggesting clinically significant outcomes. CONCLUSION: This randomized controlled study provides evidence of improved speech recognition and psychosocial outcomes following 6 weeks of TeleAR intervention. For adult post-lingually deafened CI users, including those >3 months post-activation, AR treatment can leverage neuroplasticity to maximize outcomes.

Assessment of Reliability and Validity of the Cochlear Implant Skills Review: A New Measure to Evaluate Cochlear Implant Users' Device Skills and Knowledge.

Purpose The Cochlear Implant Skills Review (CISR) was developed as a measure of cochlear implant (CI) users' skills and knowledge regarding device use. This study aimed to determine intra- and interrater reliability and agreement and establish construct validity for the CISR. Method In this study, the CISR was developed and administered to a cohort of 30 adult CI users. Participants included new CI users with less than 1 year of CI experience and experienced CI users with greater than 1 year of CI experience. The CISR administration required participants to demonstrate skills using the various features of their CI processors. Intra- and interrater reliability were assessed using intraclass correlation coefficients, agreement was assessed using Cohen's kappa, and construct validity was assessed by relating CISR performance to duration of CI use. Results Overall reliability for the entire instrument was 92.7%. Inter- and intrarater agreement were generally substantial or higher. Duration of CI use was a significant predictor of CISR performance. Conclusions The CISR is a reliable and valid assessment measure of device skills and knowledge for adult CI users. Clinicians can use this tool to evaluate areas of needed instruction and counseling and to assess users' skills over time.

Evaluation of a novel bimodal fitting formula in Advanced Bionics cochlear implant recipients.

Purpose: The study's objectives were to (1) evaluate benefit from a novel bimodal fitting formula (Adaptive Phonak Digital Bimodal Fitting Formula [APDB]), and (2) compare outcomes with APDB and a traditional fitting formula (NAL-NL2). Methods: This prospective study evaluated outcomes in ten adults with unilateral Advanced Bionics (AB) cochlear implants (CI). Participants were tested bimodally with NAL-NL2 and APDB programed on Naída Link UP HAs. Measures of speech perception, sound quality, and preference were obtained with two bimodal configurations (CI + HANAL-NL2 and CI + HAAPDB). Participants used the CI + HAAPDB configuration for an acclimation period, after which measures were repeated. Results: Significant bimodal benefit was measured from both HA fitting formulae for speech perception in noise compared to the CI-only condition. Improved individual outcomes with the APDB were observed, but group differences were not statistically significant. Participants reported subjective benefit from APDB on blind comparisons of preference and sound quality. Conclusions: Significant benefit was found with both bimodal conditions compared to the CI-only condition; however, bimodal speech perception results were not significantly different. Users reported benefit from the APDB formula over NAL-NL2 formula. Due to individual improved speech perception and overall subjective preference for APDB, clinicians should consider APDB with AB CI recipients.

Stability of audiometric measures and challenges in long-term management of the elderly cochlear implant patient.

OBJECTIVE: To determine the long-term audiometric stability and the types and frequency of management challenges encountered when working with elderly cochlear implant users. STUDY DESIGN: Retrospective chart review. SETTING: University hospital. PATIENTS: The final sample is 23 cochlear implantees over the age of 60, followed an average of 8.4 years. INTERVENTION: Rehabilitative (cochlear implantation for clinical purposes, audiologic management). MAIN CLINICAL OUTCOME MEASURES: Warble tone thresholds, spondee thresholds, speech recognition scores, and frequency counts of management problems. RESULTS: Warble tone thresholds were stable over the study period. Speech recognition performance was not significantly changed statistically over the study period, but examination of individual results showed that 26% improved in performance, 17% participants decreased, and 17% remained the same. Thirteen percent of the sample had noteworthy thinning of the flap, including one individual whose flap deteriorated and required explantation.Management challenges relating to failing health, broken and lost equipment, thinning of the skin flap, critical judgment and emotional difficulties during programming sessions, and the need for repeated instructions on device use were noted with varying frequencies. CONCLUSION: Cochlear implantation is beneficial for elderly patients with severe-profound sensorineural hearing loss as demonstrated by long-term stability of function, with the caveat that some individuals may experience significant decreases in speech recognition over time. However, unique management challenges resulting from age-related cognitive decline, health problems, and/or reduced dexterity may present themselves. Audiologists must keep these issues in mind during preoperative counseling and when structuring postoperative follow-up sessions.
