Tablet-Based Telerehabilitation Versus Conventional Face-to-Face Rehabilitation After Cochlear Implantation: Prospective Intervention Pilot Study

Computer-based Auditory Training by New Adult Cochlear Implant Recipients Is Associated With Durable Improvements in Cochlear Implant Quality of Life

OBJECTIVE

The process of adapting to communicate with a cochlear implant (CI) is complex. The use of auditory training after cochlear implantation may help to facilitate improvements in postoperative speech recognition and quality-of-life outcomes in new adult CI recipients. However, the effectiveness of auditory training remains uncertain and long-term effects have not been examined in a large sample of new adult CI users. As such, the objective of this study was to examine the influence of common forms of auditory training on speech recognition and CI-related quality-of-life (CI-related QOL) outcomes at 1 year after cochlear implantation. We hypothesized that patients who reported use of computer-based auditory training (CBAT) would show improved speech and CIQOL-35 Profile scores at 1 year after activation of their implant, compared with their peers.

DESIGN

This study was designed as a prospective study and was undertaken at a tertiary academic CI center. Participants included 114 adults undergoing cochlear implantation for bilateral hearing loss. Patients serially self-reported use of the following types of post-CI auditory training over their first-year postactivation: (1) face-to-face training (e.g., speech-language pathologist), (2) passive home-based training (e.g., listening to audiobooks), and (3) CBAT (e.g., self-directed software). Outcomes measures for this study included change in Consonant-Nucleus-Consonant phoneme (CNCp), CNC word (CNCw), AzBio sentences in quiet, and CIQOL-35 Profile global and domain scores from pre-CI to 12-mo post-CI.

RESULTS

Of 114 patients, 94 (82.5%) used one or more auditory training resources. Of these, 19.3% used face-to-face training, 67.5% passive home-based training, and 46.5% CBAT. Of 114 patients, 73 had complete CIQOL data. At 12 mo, only CBAT use was associated with significantly greater improvements in global and all domain-specific CIQOL scores ( d -range  =  0.72-0.87), compared with those not using CBAT. Controlling for demographics and use of multiple training resources, CBAT remained the strongest positive predictor of CIQOL improvement, with significant associations with global score (ß  =  12.019[4.127,19.9]) and all domain scores at 12-mo post-CI: communication (ß  =  11.937[2.456,21.318), emotional (ß  =  12.293[1.827,22.759), entertainment (ß  =  17.014[5.434,28.774), environment (ß  =  13.771[1.814,25.727]), listening effort (ß  =  12.523[2.798,22.248]), and social (ß  =  18.114[7.403,28.826]). No significant benefits were noted with use of CBAT or any other form of auditory training and speech recognition scores at 12-mo post-CI ( d -range  =  -0.12-0.22).

CONCLUSIONS

Auditory training with CBAT was associated with improved CI-related QOL outcomes at 12-mo post-CI. Given its availability and low cost, this study provides evidence to support using CBAT to improve real-world functional abilities in new adult CI recipients.

Hearing Rehabilitation With a Chat-Based Mobile Auditory Training Program in Experienced Hearing Aid Users: Prospective Randomized Controlled Study

Background

Hearing rehabilitation with auditory training (AT) is necessary to improve speech perception ability in patients with hearing loss. However, face-to-face AT has not been widely implemented due to its high cost and personnel requirements. Therefore, there is a need for the development of a patient-friendly, mobile-based AT program.

Objective

In this study, we evaluated the effectiveness of hearing rehabilitation with our chat-based mobile AT (CMAT) program for speech perception performance among experienced hearing aid (HA) users.

Methods

A total of 42 adult patients with hearing loss who had worn bilateral HAs for more than 3 months were enrolled and randomly allocated to the AT or control group. In the AT group, CMAT was performed for 30 minutes a day for 2 months, while no intervention was provided in the control group. During the study, 2 patients from the AT group and 1 patient from the control group dropped out. At 0-, 1- and 2-month visits, results of hearing tests and speech perception tests, compliance, and questionnaires were prospectively collected and compared in the 2 groups.

Results

The AT group (n=19) showed better improvement in word and sentence perception tests compared to the control group (n=20; P=.04 and P=.03, respectively), while no significant difference was observed in phoneme and consonant perception tests (both P>.05). All participants were able to use CMAT without any difficulties, and 85% (17/20) of the AT group completed required training sessions. There were no changes in time or completion rate between the first and the second month of AT. No significant difference was observed between the 2 groups in questionnaire surveys.

Conclusions

After using the CMAT program, word and sentence perception performance was significantly improved in experienced HA users. In addition, CMAT showed high compliance and adherence over the 2-month study period. Further investigations are needed to validate long-term efficacy in a larger population.

Comparing the Clinical Effectiveness of Telerehabilitation with Traditional Speech and Language Rehabilitation in Children with Hearing Disabilities: A Systematic Review

Introduction: The use of telerehabilitation for the treatment of speech and language disorders in the field of hearing is increasing. A comprehensive study comparing telerehabilitation's effectiveness with traditional rehabilitation can help us understand it better. Therefore, this systematic review aimed to compare the effectiveness of telerehabilitation with traditional rehabilitation for speech and language disorders in children with hearing disabilities in 2023. Methods: A systematic search was conducted in PubMed, PubMed Central, Cochrane, Scopus, Google Scholar, Science Direct, and the Web of Science from 2000 to February 28, 2023. The articles were selected based on keywords, determined criteria, and reviewed in terms of title, abstract, and full text. Finally, articles that were relevant to our aim were evaluated. Results: The initial search resulted in the extraction of 1,788 articles. After reviewing the articles and applying the inclusion and exclusion criteria, nine articles were selected for analysis. Four (44.44%) and 3 (33.33%) studies were case-control and quasi-experimental studies, respectively. Four (44.44%) studies were conducted in the United States. SPSS, Preschool Language Scales, fifth edition (PLS-5), and microphone were the most common tools, each of which included 4 (44.44%), 3 (33.33%), and (333.33%) studies. Conclusions: Traditional rehabilitation and telerehabilitation can effectively improve the speech and language skills of children with hearing disabilities. However, it is always suggested to use traditional rehabilitation first to achieve better results.

Systematic Review of Auditory Training Outcomes in Adult Cochlear Implant Recipients and Meta-Analysis of Outcomes

Objective: to review evidence on the efficacy of auditory training in adult cochlear implant recipients. Data Sources: PRISMA guidelines for a systematic review of the literature were followed. PubMed, Scopus, and CINAHL databases were queried on 29 June 2023 for terms involving cochlear implantation and auditory training. Studies were limited to the English language and adult patient populations. Study Selection: Three authors independently reviewed publications for inclusion in the review based on a priori inclusion and exclusion criteria. Inclusion criteria encompassed adult cochlear implant populations, an analysis of clinician- or patient-directed auditory training, and an analysis of one or more measures of speech recognition and/or patient-reported outcome. Exclusion criteria included studies with only pediatric implant populations, music or localization training in isolation, and single-sample case studies. Data Extraction: The data were collected regarding study design, patient population, auditory training modality, auditory training timing, speech outcomes, and data on the durability of outcomes. A quality assessment of the literature was performed using a quality metric adapted from the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) Working Group guidelines. Data Synthesis and Meta-Analysis: Data were qualitatively summarized for 23 studies. All but four studies demonstrated significant improvement in at least one measured or patient-reported outcome measure with training. For 11 studies with sufficient data reporting, pre-intervention and post-intervention pooled means of different outcome measures were compared for 132 patients using meta-analysis. Patient-direct training was associated with significant improvement in vowel-phoneme recognition and speech recognition in noise (p < 0.05 and p < 0.001, respectively), and clinician-directed training showed significant improvement in sentence recognition in noise (p < 0.001). Conclusions: The literature on auditory training for adult cochlear implant recipients is limited and heterogeneous, including a small number of studies with limited levels of evidence and external validity. However, the current evidence suggests that auditory training can improve speech recognition in adult cochlear implant recipients.

Sustainable Benefits of High Variability Phonetic Training in Mandarin-speaking Kindergarteners With Cochlear Implants: Evidence From Categorical Perception of Lexical Tones

OBJECTIVES

Although pitch reception poses a great challenge for individuals with cochlear implants (CIs), formal auditory training (e.g., high variability phonetic training [HVPT]) has been shown to provide direct benefits in pitch-related perceptual performances such as lexical tone recognition for CI users. As lexical tones in spoken language are expressed with a multitude of distinct spectral, temporal, and intensity cues, it is important to determine the sources of training benefits for CI users. The purpose of the present study was to conduct a rigorous fine-scale evaluation with the categorical perception (CP) paradigm to control the acoustic parameters and test the efficacy and sustainability of HVPT for Mandarin-speaking pediatric CI recipients. The main hypothesis was that HVPT-induced perceptual learning would greatly enhance CI users' ability to extract the primary pitch contours from spoken words for lexical tone identification and discrimination. Furthermore, individual differences in immediate and long-term gains from training would likely be attributable to baseline performance and duration of CI use.

DESIGN

Twenty-eight prelingually deaf Mandarin-speaking kindergarteners with CIs were tested. Half of them received five sessions of HVPT within a period of 3 weeks. The other half served as control who did not receive the formal training. Two classical CP tasks on a tonal continuum from Mandarin tone 1 (high-flat in pitch) to tone 2 (mid-rising in pitch) with fixed acoustic features of duration and intensity were administered before (pretest), immediately after (posttest), and 10 weeks posttraining termination (follow-up test). Participants were instructed to either label a speech stimulus along the continuum (i.e., identification task) or determine whether a pair of stimuli separated by zero or two steps from the continuum was the same or different (i.e., discrimination task). Identification function measures (i.e., boundary position and boundary width) and discrimination function scores (i.e., between-category score, within-category score, and peakedness score) were assessed for each child participant across the three test sessions.

RESULTS

Linear mixed-effects (LME) models showed significant training-induced enhancement in lexical tone categorization with significantly narrower boundary width and better between-category discrimination in the immediate posttest over pretest for the trainees. Furthermore, training-induced gains were reliably retained in the follow-up test 10 weeks after training. By contrast, no significant changes were found in the control group across sessions. Regression analysis confirmed that baseline performance (i.e., boundary width in the pretest session) and duration of CI use were significant predictors for the magnitude of training-induced benefits.

CONCLUSIONS

The stringent CP tests with synthesized stimuli that excluded acoustic cues other than the pitch contour and were never used in training showed strong evidence for the efficacy of HVPT in yielding immediate and sustained improvement in lexical tone categorization for Mandarin-speaking children with CIs. The training results and individual differences have remarkable implications for developing personalized computer-based short-term HVPT protocols that may have sustainable long-term benefits for aural rehabilitation in this clinical population.

A systematic review of economic analyses of home-based telerehabilitation

PURPOSE

Telerehabilitation, or the delivery of rehabilitation using information and communication technologies, may improve timely and equitable access to rehabilitation services at home. A systematic literature review was conducted of studies that formally documented the costs and effects of home-based telerehabilitation versus in-person rehabilitation across all health conditions.

MATERIALS AND METHODS

Six electronic databases were searched from inception to 13 July 2021 (APA, PsycInfo, CINAHL, Embase, EmCare, Medline (Ovid), and PubMed) using a protocol developed by a medical librarian. A quality appraisal of full economic evaluation studies was conducted using the Drummond 10-point quality checklist.

RESULTS

Thirty-five studies were included in this review covering various rehabilitation types and diverse populations. The majority were published in the last six years. Available evidence suggests that telerehabilitation may result in similar or lower costs as compared to in-person rehabilitation for the health care system and for patients. However, the impact of telerehabilitation on long-term clinical outcomes and health-related quality of life remains unclear.

CONCLUSIONS

More high quality and robust economic evaluations exploring the short- and long-term costs and other impacts of telerehabilitation on patients, caregivers, and health care systems across all types of patient populations are still required.Implications for rehabilitationHome-based telerehabilitation may reduce barriers in access to care for individuals living in the community.Economic analyses can inform health care system decision-making by evaluating the costs and effects associated with telerehabilitation.This study found that telerehabilitation may result in similar or lower costs as in-person rehabilitation; however, its impact on health-related quality of life is unclear.

[Teletherapy after cochlear implantation during the COVID-19 pandemic]

BACKGROUND

Due to the COVID-19 pandemic, digitalization in healthcare grew rapidly. Auditory training after cochlear implantation usually takes place face-to-face but social distancing interferes with this therapeutic approach.

MATERIALS AND METHODS

In follow-up treatment, 42 adult cochlear implant (CI) users aged 53.8 (±15.6) years received video therapy 1 x/week for 5 weeks on a certified platform. After each therapy session, the technical process and therapeutic content were assessed. At the end of the study, usability and the relationship between therapist and patient were evaluated by patients and therapists using the System Usability Scale (SUS), a final questionnaire and by the Skala Therapeutische Allianz - Revised (STA-R). Furthermore, a cost-benefit analysis was done.

RESULTS

Usability for both users was high (87.97 versus 93.0). Despite the lack of personal contact, therapeutic alliance was highly appreciated by patients and therapists (87.8% versus 84.8%). The main advantages for the patients were reductions in time and costs. In contrast, the rehabilitation center faced higher costs initially due to the longer time therapists needed to prepare the lessons. Technical problems had to be solved in > 75% of the first sessions but did not bother training thereafter. In total, 47.6% of the patients believe that teletherapy can completely fulfill their therapeutic needs.

CONCLUSION

Video therapy has been judged as a useful tool by all users and the majority wants to continue. However, it remains questionable whether the therapist-patient relationship can be sufficiently maintained over a longer period and whether online therapy is as effective as face-to-face therapy.

Outcome Measures Following Tele-rehabilitation and Conventional Face to Face Rehabilitation in Paediatric Cochlear Implant Users during COVID-19 Pandemic: A Pilot Study in a Tertiary Care Setup

Background

Following the COVID-19 pandemic, majority of paediatric cochlear implantees (CI) lost follow ups for rehabilitation and tele-therapy was initiated. Present study thus compared the outcome measures of paediatric CI users on tele-therapy versus conventional face to face therapy following COVID-19 pandemic.

Method

Twenty seven unilateral paediatric cochlear implantees in the age range of 2–11 years were divided into two groups based on the therapy modality, viz, tele- and face-to-face therapy. Based on the hearing age, participants were further divided into three groups, viz, 0–2, 2–4, and greater than four years. A complete the test battery comprising Integrated Scales of Development, Speech Intelligibility Rating scale, and Revised Categorical Auditory Perception were administered. The speech & language test battery was performed prior to initiating the rehabilitation and post 12 months of rehabilitation.

Results

Results of the present study revealed that conventional rehabilitation had better outcomes compared to teletherapy. The rate of progress after one year of rehabilitation with respect to hearing-age showed a significant difference for the hearing-age group of 0–2 years across the domains of audition, speech and language.

Conclusion

The present study indicates that conventional method of the speech-language and auditory rehabilitation is far better compared to the tele rehabilitation services especially for those visiting tertiary care hospitals as most of them belong to lower and middle socioeconomic status. From the results, it can be delineated that with lesser hearing experience, paediatric CI users always need to initially enroll for conventional therapy for better speech-language and auditory outcomes.
