Electroacoustic evaluation of the bone conduction transducer B250 for vestibular and hearing diagnostics in comparison with Radioear B71 and B81.

International Journal of Epidemiology

The objective is to evaluate the electroacoustic performance of the B250 transducer and to compare it with the two most widely used audiometric transducers B71 and B81.

The electroacoustic performance was evaluated in terms of sensitivity level, distortion, maximum hearing level and electrical impedance.

Six B250 prototype transducers were evaluated and compared with published data of B71 and B81 together with complementary measurements of maximum hearing level at 125 Hz and phase of electrical impedance. Differences in reference equivalent threshold vibratory force levels were estimated by comparing hearing threshold measurements of 60 healthy ears using B81 and B250.

B250 has approximately 27 dB higher sensitivity levels than both B71 and B81 at 250 Hz and can generate higher maximum hearing level at low frequencies: 11.8 to 35.8 dB (125-1000 Hz) higher than B71, and 1.4 to 18.6 dB (125-750 Hz) higher than B81. The maximum average difference in reference threshold force levels was 13.5 ± 8.7 dB higher for B250 at 250 Hz compared to B81.

B250 can produce higher output force with less distortion than B71 and B81, especially at 125 and 250 Hz, which could possibly improve low frequency investigations of the audio-vestibular system.

The role of cochlear and vestibular afferents in long-latency cervical vestibular evoked myogenic potentials.

International Journal of Epidemiology

To examine the origin of cervical vestibular evoked myogenic potential (cVEMP) late waves (n34-p44) elicited with air-conducted click stimuli.

Using a retrospective design, cVEMPs from normal volunteers were compared to those obtained from patients with vestibular and auditory pathologies.

(1) Normal volunteers (n = 56); (2) severe-to-profound sensorineural hearing loss (SNHL) with normal vestibular function (n = 21); (3) peripheral vestibular impairment with preserved hearing (n = 16); (4) total vestibulocochlear deficit (n = 23).

All normal volunteers had ipsilateral-dominant early p13-n23 peaks. Late peaks were present bilaterally in 78%. The p13-n23 response was present in all patients with SNHL but normal vestibular function, and 43% had late waves. Statistical comparison of these patients to a subset of age-matched controls showed no significant difference in the frequencies, amplitudes or latencies of their ipsilateral early and late peaks. cVEMPs were absent in all patients with vestibular impairment.

The presence of long-latency cVEMP waves was not dependent on the integrity of sensorineural hearing pathways, but instead correlated with intact vestibular function. This finding conflicts with the view that these late waves are cochlear in origin, and suggests that vestibular afferents may assume a more prominent role in their generation.

Adults' recollections of discussions with their audiologist: a qualitative study of what was and was not successfully communicated about listening difficulties.

International Journal of Epidemiology

Some adults experience challenges in successfully communicating their listening difficulties to their audiologist, and report feeling that they are not always listened to or understood. This project examined adults' recollections of discussions with their audiologist to explore (1) how adults report describing their listening difficulties and (2) information that adults report they do not communicate, or do not communicate successfully, to their audiologist.

Individual semi-structured interviews were conducted. Interview transcripts were analysed using a template analysis approach.

Fifteen adults who self-report listening difficulties, and who had previously consulted an audiologist.

Four themes were identified from adults' recollections of how they describe their listening difficulties: (1) situation or context of listening difficulties, (2) behavioural responses, (3) impacts of listening difficulties and (4) contributing factors. Adults report not always successfully communicating (1) emotional concerns and impacts, (2) descriptions of sound quality and (3) descriptions of changed listening experiences.

Results provide insights about the times when adults feel that communication with their audiologist is successful, or unsuccessful. The results are useful for informing interventions to help adults and audiologists communicate more effectively together. To further inform interventions, factors affecting adults' communication should be explored.

Evaluating calcium channel blockers and bisphosphonates as otoprotective agents in cochlear implantation hearing preservation candidates.

Cochlear Implants International

Evaluate potential effects of calcium channel blockers (CCB) and bisphosphonates (BP) on residual hearing following cochlear implantation.

Medications of 303 adult hearing preservation (HP) candidates (low frequency pure tone average [LFPTA] of 125, 250, and 500 Hz ≤80 dB HL) were reviewed. Postimplantation LFPTA of patients taking CCBs and BPs were compared to controls matched by age and preimplantation LFPTA.

Twenty-six HP candidates were taking a CCB (N = 14) or bisphosphonate (N = 12) at implantation. Median follow-up was 1.37 years (range 0.22-4.64y). Among subjects with initial HP, 29% (N = 2 of 7) CCB users compared to 50% (N = 2 of 4) controls subsequently lost residual hearing 3-6 months later (OR = 0.40, 95% CI = 0.04-4.32, p = 0.58). None of the four BP patients with initial HP experienced delayed loss compared to 50% (N = 2 of 4) controls with initial HP (OR = 0.00, 95% CI = 0.00-1.95, P = 0.43). Two CCB and one BP patients improved to a LFPTA <80 dB HL following initial unaided thresholds that suggested loss of residual hearing.

There were no significant differences in the odds of delayed loss of residual hearing with CCBs or BPs.

Further investigation into potential otoprotective adjuvants for maintaining residual hearing following initial successful hearing preservation is warranted, with larger cohorts and additional CCB/BP agents.

Effects of Exercise-Induced Laryngeal Obstruction in Adolescents: A Qualitative Study.

Speech Language Path

The purpose of this study was to examine the influence of exercise-induced laryngeal obstruction (EILO) on adolescents.

Twenty patients (< 17 years) diagnosed with EILO participated in this study. Patients completed semistructured interviews examining their experience with the health care system, treatment, and the effects of EILO symptoms on quality of life. Interviews were analyzed using a combination of directed and conventional content analyses. Researchers identified seven overarching themes either prior to or during analysis, and 24 subthemes were inductively identified from patient interviews using open, axial, and selective coding.

On average, patients went 1.9 years between symptom onset and EILO diagnosis. Patients described symptom onset as frightening and confusing. Even after initially reporting symptoms to a medical provider, patients went an average of 10.5 months before diagnosis. Patients perceived that delays in diagnosis prevented efficient management and allowed symptoms to escalate. Patients reported that EILO detrimentally influenced athletic performance, forcing them to pace themselves or cease participation altogether. Social and academic effects of EILO included missed classes, difficulty in physical education courses, and resentment from teammates if athletic performance declined. Both athletes and nonathletes indicated that EILO elicited feelings of fear, frustration, dread, guilt, and embarrassment. Patients reported that therapy with a speech-language pathologist (SLP) effectively addressed symptoms; however, employing rescue breathing techniques was often more difficult than anticipated.

Physical and emotional sequelae associated with EILO may have widespread influence on patient quality of life. Therapy with an SLP reportedly ameliorated EILO symptoms; however, patients indicated that delayed diagnosis allowed negative effects to intensify prior to treatment.

Evaluating structure and content of parent-implemented early logopaedic intervention models following the three stages of communicative development in children with cleft lip and/or palate: Systematic literature review with narrative synthesis.

Int J Lang

The development of communication, speech and language follows three stages (development of the parent-child relationship, interactions and actual speech and language acquisition). Children born with cleft lip and/or palate are at increased risk of communicative problems while parents may be going through an emotionally difficult time. Early parent-implemented logopaedic intervention that supports both parents and child is important. Three systematic reviews have examined the effects of early speech and language interventions, but not their structure and content.

To investigate which early parent-implemented logopaedic interventions already exist for children with cleft lip and/or palate, and to evaluate their structure, content and time of onset against the three stages of communicative development.

Six databases (PubMed, Embase, Web of Science, APA PsycInfo, Cinahl and Scopus) were searched between inception and 31 March 2023 to identify published articles that reported early parent-implemented logopaedic interventions in children with cleft lip and/or palate, aged 0 to 3 years, clearly describing the strategies used to train parents. Two authors independently assessed the eligibility of the studies. Quality assessment was conducted using the Physiotherapy Evidence Database quality assessment tool, Single-Case Experimental Design tool and the National Institutes of Health pre-post-study tools. The structure and content of the interventions were analysed taking into account the needs and difficulties of both the parents and the child according to the three stages of communicative development.

The systematic literature search identified four studies that met the inclusion criteria. Three of them had a Level of Evidence III and one study had a Level of Evidence IV. Strategies appropriate for Stage 1 of communicative development (parent-child relationship) are well represented in only one study, but the psychosocial needs of parents are currently not included in these programmes. However, research shows that parental emotional difficulties can adversely impact a child's communicative development. Strategies appropriate for Stage 2 (promoting social interactions) are better represented. However, strategies appropriate for Stage 3 (acquiring correct speech and language patterns) are most represented in all intervention programmes.

What is already known on the subject Children with cleft lip and/or palate are at increased risk of speech and language problems from birth. Parents of these children often have emotional problems following their child's diagnosis. The effectiveness of early intervention to facilitate the child's speech and language development has already been proven. Early intervention is recommended for both parents and child, but little is known about early parent-implemented logopaedic interventions that also provide psychosocial support for parents. What this paper adds to existing knowledge This review has shown that existing early parent-implemented logopaedic interventions for children with cleft lip and/or palate focus mainly on facilitating responsive interactions and actual speech and language development (Stages 2 and 3 of communicative development). However, Stage 1, where the parent-child relationship develops, is currently not included, even though this stage is a prerequisite of subsequent stages. If parents are struggling with emotional problems (following their child's diagnosis) this can negatively impact their mental health, the parent-child relationship, attachment and their child's development. What are the potential or actual clinical implications of this work? A clinical implication of the findings in this review is that more attention should be paid to Stage 1 of communicative development in early parent-implemented logopaedic interventions. By working closely with the psychologist of the cleft (and craniofacial) team, any psychosocial needs of the parents can be included in the counselling. As a result, the parents and their child are seen and supported as a unit and the parent-child relationship can develop optimally.

Impaired speech input and output processing abilities in children with cleft palate speech disorder.

Int J Lang

Cleft lip and palate is one of the most common oral and maxillofacial deformities associated with a variety of functional disorders. Cleft palate speech disorder (CPSD) occurs the most frequently and manifests a series of characteristic speech features, which are called cleft speech characteristics. Some scholars believe that children with CPSD and poor speech outcomes may also have weaknesses in speech input processing ability, but evidence is still lacking so far.

(1) To explore whether children with CPSD and speech output disorders also have defects in speech input processing abilities; (2) to explore the correlation between speech input and output processing abilities.

Children in the experimental group were enrolled from Beijing Stomatological Hospital, Capital Medical University, and healthy volunteers were recruited as controls. Then three tasks containing real and pseudo words were performed sequentially. Reaction time, accuracy and other indicators in three tasks were collected and then analysed.

The indicators in the experimental group were significantly lower than those in the control group. There was a strong correlation between speech input and output processing tasks. The performance of both groups when processing pseudo words in the three tasks was worse than that when dealing with real words.

What is already known on the subject Children with cleft lip and palate often have speech sound disorders known as cleft palate speech disorder (CPSD). CPSD is characterised by consonant errors called cleft speech characteristics, which can persist even after surgery. Some studies suggest that poor speech outcomes in children with CPSD may be associated with deficits in processing speech input. However, this has not been validated in mainland China. What this paper adds to existing knowledge The results of our study indicate that children with CPSD exhibit poorer performance in three tasks assessing speech input and output abilities compared to healthy controls, suggesting their deficits in both speech input and output processing. Furthermore, a significant correlation was observed between speech input and output processing abilities. Additionally, both groups demonstrated greater difficulty in processing pseudo words compared to real words, as evidenced by their worse performance in dealing with pseudo words. What are the potential or actual clinical implications of this work? The pseudo word tasks designed and implemented in our study can be employed in future research and assessment of speech input and output abilities in Chinese Mandarin children with CPSD. Additionally, our findings revealed the significance of considering both speech output processing abilities and potential existence of speech input processing ability for speech and language therapists when evaluating and developing treatment options for children with CPSD as these abilities are also important for the development of literacy development.

Criterion (Concurrent) Validity and Clinical Utility of the Tongueometer Device.

Speech Language Path

Tongue manometry (i.e., tongue pressure measurement) is a commonly used assessment for patients with suspected oral-motor involvement in swallowing disorders. Availability of lingual manometry has changed in recent years, with the introduction of the Tongueometer device being a more affordable tongue manometry system. The purpose of this study was to test concurrent (criterion) validity of the Tongueometer compared to the current standard reference device, the Iowa Oral Performance Instrument (IOPI).

Adults without dysphagia were recruited for participation in this study. Standard lingual measurements (swallowing-related pressures, maximum isometric pressure [MIP], and maximum isometric endurance) were recorded, with the bulb anteriorly placed, with both devices, in a randomized order. The Bland-Altman method was used to determine concurrent (criterion) validity of these measurements compared to the clinical standard IOPI device. A recently available suggested corrective value by Curtis et al. (2023) was also applied, with comparisons made between devices both with and without the Curtis correction.

The final sample included 70 adult participants aged 20-89 years (Mage = 52.3 years). Measures with the Tongueometer device were significantly lower when compared with the same measures taken using the IOPI (p < .01) for all measures including MIP, endurance, and swallow pressures. The correction suggested by Curtis and colleagues did not ameliorate these differences.

The Tongueometer lingual measurements were consistently lower compared to the IOPI. Clinical use of values taken with the Tongueometer device should be compared to normative data published for each specific device. Available features of each device (e.g., display, bulb texture, technology/application) should be considered when selecting which device to use with an individual patient.

Exploring Health-Related Social Needs and Components of Social Competence Following Childhood Traumatic Brain Injury.

Speech Language Path

Health-related social needs (HRSNs) impact general health care and educational outcomes for children with traumatic brain injury (TBI) and their families. Furthermore, children with TBI of all severities experience negative social competence outcomes chronically postinjury. However, studies have not investigated the relationship between HRSNs and social competence outcomes for children after TBI. The aim of this study was to identify the relationship between HRSNs and components of social competence (i.e., social skills, social communication, family functioning, and behavioral domains per the biopsychosocial framework for social competence) for children with TBI, per parent report.

This study used a prospective, cross-sectional study design with a convenience sample. Online surveys were completed by parents of children with TBI (N = 22). On average, children with TBI were 4.84 years old at the time of their TBI and 9.24 years old at the time of study participation.

Having a parent identify an HRSN in the domain of mental health was associated with social communication and family functioning difficulties for children with TBI. Statistically significant relationships were found between social communication and family functioning, externalizing behavior, and total behavior; family functioning and social relations; and family functioning and externalizing behavior.

The findings of this study support that children with TBI experience chronic deficits in components of social competence, and HRSNs are associated with these outcomes. Further research needs to consider HRSNs to improve equitable prevention, supports, and services for children with TBI.

Effects of Cervical Bracing on Elderly Patients With Dysphagia.

Speech Language Path

This study aimed to determine if cervical bracing with a PMT collar increases risk of airway invasion and pharyngeal residue in elderly patients with dysphagia. Additionally, it aimed to identify patient preference for cervical bracing during deglutition.

Twenty-one patients underwent a videofluoroscopic swallow study. Thin liquid, nectar thick liquid, pudding, and cracker were administered with cervical collar on and off with order of condition randomized. The Penetration-Aspiration Scale (PAS) was used to grade swallows, with McNemar's test of symmetry used to determine whether the categorical PAS score was similar between conditions. Pharyngeal residue was measured following swallows. Patients were asked which condition they preferred, and which was more comfortable with "no difference" being a selection.

No significant difference in PAS categorization score was measured for any consistency (p = .317-.919). Significantly more pyriform sinus residue was measured in the collar off condition (p = .003), albeit amounts were within normative range, with no difference measured in vallecula residue between conditions (p = .939). Forty-five percent of participants preferred to swallow with the collar off, while 55% indicated no preference. Forty-one percent of participants indicated increased comfort with collar off, while 59% indicated no difference in comfort. No participant preferred swallowing or indicated increased comfort with the collar on.

Presence of a cervical collar in elderly patients with dysphagia did not result in a significant difference in airway invasion or total pharyngeal residue. There was significantly more residue in the pyriform sinuses when cervical bracing was removed. The majority of patients did not indicate a difference in preference or comfort between collar on/off conditions.

Safety-Seeking Behaviors and Anxiety Maintenance in People With Aphasia: A Viewpoint.

Speech Language Path

People with aphasia (PWA) often experience higher levels of anxiety and social isolation than people without aphasia. Although the presence of anxiety is appreciated in PWA, literature examining the etiology and persistent nature of anxiety in PWA is underdeveloped. Safety-seeking behaviors, or maladaptive acts used by individuals to decrease anxiety from a feared outcome, have been reported as key facilitators of long-term anxiety toward feared situations across a variety of clinical populations. The purpose of this viewpoint is to explore the concept of safety-seeking behaviors and discuss their potential relevance to the maintenance of anxiety in PWA. We further discuss the distinction between maladaptive (i.e., safety seeking) and adaptive (i.e., coping) behaviors and how this knowledge may improve the quality of clinical services for PWA.

The present review advocates for further exploration of the safety-seeking behaviors that are used by PWA. Until critical attention is given to this subject, clinicians may remain ill-equipped to identify and depict whether a self-management strategy is facilitative or inhibitive to PWA's communicative participation goals. Critically, a behavior that may be "maladaptive" for one individual may be "adaptive" for another. Future research should seek to identify common behavioral and cognitive strategies that PWA implement to reduce acute perceptions of anxiety. This knowledge may help facilitate holistic aphasia rehabilitation by allowing clinicians to foster conversations around behaviors that inhibit or promote successful communicative participation.

Montreal Cognitive Assessment Scores Do Not Associate With Communication Challenges Reported by Adults With Alzheimer's Disease or Parkinson's Disease.

Speech Language Path

Screening for cognitive-communication challenges in people with Alzheimer's disease (AD) or Parkinson's disease (PD) may benefit from multiple kinds of information about the client (e.g., patient-reported, performance-based). The purposes of this report are (a) to describe, using recently published score range descriptors (e.g., "mild," "moderate"), the patient-reported communication challenges of people with AD or PD using the Communicative Participation Item Bank (CPIB) and the Aphasia Communication Outcome Measure (ACOM); and (b) to examine the relationships between the performance-based Montreal Cognitive Assessment (MoCA), a cognitive screener, and patient-reported CPIB and ACOM scores.

Participants were a convenience sample of 49 community-dwelling adults with AD or PD. Participants completed the measures in person as part of a larger assessment battery.

MoCA total scores ranged from 7 to 28. CPIB T-scores fell in the following ranges: 31% were "within normal limits," 57% reflected "mildly" restricted participation, and 12% reflected "moderately" restricted participation. ACOM T-scores fell in the following ranges: 50% were either "within normal limits" or reflected "mild" impairment, 29% reflected "mild-moderately" impaired functional communication, and 21% reflected "moderately" impaired functional communication. There were only weak and nonsignificant correlations between T-scores on the ACOM or CPIB and scores on the MoCA, and there were no group differences on the ACOM or CPIB between individuals who screened positive versus negative on the MoCA.

When screening individuals with AD or PD, patient-reported communication challenges seem to be complementary to information provided by the MoCA and perhaps most useful in screening for mild communication challenges.
