Introduction:  Benign paroxysmal positional vertigo (BPPV) has a prevalence of 58% in a traumatic brain injury (TBI) population. Research on idiopathic BPPV has demonstrated a higher prevalence of right-sided canal involvement. While many studies have investigated the epidemiology of canal involvement in BPPV in both idiopathic and traumatic BPPV (BPPV associated with a fall), there has been no assessment of trauma location as a predictor of the location of BPPV.

Objectives:  The aim of this study was to assess the relationship between the location of a focal TBI and canal involvement in BPPV.

Methods:  Patients who were admitted to an inpatient rehabilitation unit with a diagnosis of TBI were screened for BPPV. The primary outcome of this study was the side of the TBI, the BPPV type (posterior, horizontal, or anterior canal), and the side of the BPPV (right, left, or bilateral).

Results:  There were 42 people who had BPPV. Twenty-one had right-sided canal involvement, 14 had left-sided involvement, and 7 had bilateral involvement. Sixteen had right-side tissue involvement, 13 had left-side involvement, and 13 had bilateral involvement. There was no significant correlation between variables (χ²= 1.70, p = 0.80).

Conclusion:  All patients with a TBI should have all canals assessed for BPPV as there is no relationship between the side of focal damage and canal involvement.

Background:  This study evaluated the effects of coronavirus disease 2019 (COVID-19) on the cochlea and auditory efferent system with transient evoked otoacoustic emissions (TEOAE) and contralateral suppression (CS).

Objective:  We aimed to evaluate the pre- and post-COVID-19 TEOAE and CS results in the same participants to reveal the effect of COVID-19 on the efferent auditory system.

Study design:  The CS measurement was performed twice for each participant before a diagnosis of COVID-19 and after treatment for COVID-19 as a within-subjects study design. All participants exhibited hearing thresholds below 25 dB HL at all frequencies and all participants demonstrated bilateral Type A tympanograms. The tests were performed in the linear mode using a double probe on the Otodynamics ILO292-II device. The CS of the otoacoustic emissions was measured at 65 dB peSPL TEOAE stimulus and 65 dB SPL broadband noise. All parameters including reproducibility, noise, and stability were considered during the measurements.

Study samples:  The study included 11 patients (eight females and three males) aged between 20 and 35 years (mean age, 26 ± 3.66).

Data collection and analysis:  Wilcoxon signed rank test and Spearman's correlation test were used for statistical analysis using the Statistical Package for the Social Sciences version 23.0.

Results:  The Wilcoxon signed rank test showed that there was no significant difference between the pre-and post-COVID-19 TEOAE CS results in all tested frequencies and measurement parameters, 1000 to 4000 Hz, Z = -0.356, -0.089, -0.533, -0.533, -1.156, and p < 0.05. Although not statistically significant, the CS results obtained post-COVID-19 at all frequencies, except 4000 Hz, were lower than those before COVID-19. According to the overall TEOAE results after COVID-19, a statistically significant decrease was observed at 3000 Hz (Z = -2.847, p < 0.01) and 4000 Hz (Z = -2.401, p < 0.05) compared with the premeasurement.

Conclusions:  The study findings show that severe acute respiratory syndrome coronavirus 2 can affect the cochlea and the auditory efferent system in adults. Post-COVID-19 audiological evaluation can also be considered part of a general medical examination.

Background:  Vestibular migraine is associated with vertigo, persistent swaying, tilting, and disorientation, which suggests a heightened sensitivity of the neural mechanisms subserving spatial orientation. Whether a heightened sense of motion to vestibular stimulation in vestibular migraine is associated with sensitivity to visual motion (visual dependency) or physical motion (motion sickness susceptibility) is unclear.

Purpose:  The aim of this study was to explore whether a heightened sense of self-motion sensitivity in vestibular migraine is associated with visual dependency or motion sickness susceptibility.

Study design:  This is a prospective cross-over study.

Study sample:  Fifteen participants with vestibular migraine and 20 healthy controls (all right handed) were included in this study.

Data collection and analysis:  In the main experiment, participants were asked to align a rod to the perceived head position. Head tilt was generated by DC galvanic vestibular stimulation at 1 mA to produce head tilts to the right (left anodal/right cathodal stimulation, LA/RC) or left (right anodal/left cathodal, RA/LC). The perception of head tilt was measured in a dark room using laptop software that allowed participants to turn an illuminated rod to any angle about the midpoint. Participants were instructed to align the rod to the perceived head position before and during galvanic stimulation and the line angle was saved. Head position was objectively monitored with an ultrasound motion system. After completing the perceptual test, visual dependency was measured with a static and rotating background and the Motion Sickness Susceptibility Questionnaire (MSSQ) was completed.

Results:  In an upright head position, without stimulation, the perceived head position was 1.1 degrees in controls and -0.69 degrees in vestibular migraine participants with no significant difference between groups. During galvanic vestibular stimulation, participants with vestibular migraine had an increased perception of head tilt compared with controls (RA/LC: controls -4.7 degrees and vestibular migraine -9.29, p = 0.002; and LA/RC: controls 6.5 degrees and vestibular migraine 11.12 degrees, p = 0.017), although the size of head movement was similar between groups. The average perception of head tilt correlated to the MSSQ score, but not to the degree of visual dependency in a static or moving background.

Conclusion:  A heightened sensitivity of the vestibular system to vestibular stimulation in vestibular migraine is consistent with reports of self-motion sensitivity in vestibular migraine.

Background:  There is limited evidence demonstrating the ability of audiometric bone vibrators to elicit ocular vestibular evoked myogenic potentials (oVEMPs). The RadioEar B71 bone vibrator has insufficient power output to reliably evoke oVEMPs, which has previously left nonaudiometric and nonmedically approved devices such as the Brüel & Kjær Mini-shaker 4810 as the only feasible alternative. The newer RadioEar B81 model has a higher power output than its predecessor, but evidence for its suitability for eliciting oVEMPs has so far been mixed. This variability may be due to factors other than simply the power output, such as whether sufficient static force is applied to hold the transducer in place and transfer vibratory energy into the bone.

Purpose:  This study aimed to test the hypothesis that bone-conducted oVEMPs can be obtained with the B81 that are equivalent to those from the Mini-shaker, the de facto gold-standard transducer for this response, when the outputs of the two transducers are matched and they are coupled with sufficient static force.

Research design:  oVEMPs elicited by both transducers were recorded in a counterbalanced within-groups design.

Study sample:  Sixteen healthy adults (12 female; 22-47 years) with no history of hearing, balance, or neurological disorders were included in the study.

Data collection and analysis:  One-cycle alternating tone-burst stimuli at 500 Hz were delivered to the mastoid from each transducer. The vibratory force levels were matched at 127 dB peak-to-peak equivalent force levels, and both were held in place with a static force around 10 N. oVEMP waveforms were gathered from the contralateral eye using the belly-tendon montage and were assessed for statistical equivalence.

Results:  There was an absence of any statistically significant difference in N10 and N10-P15 amplitudes in oVEMPs from each transducer.

Conclusions:  Our results indicate that B81 can elicit oVEMPs with no meaningful differences to those from the Mini-shaker, provided effective stimulus levels are matched and static force is sufficient. Although further work is necessary to investigate equivalence at other stimulus frequencies and stimulation sites, the results support the use of the B81 to elicit 500Hz oVEMPs at the mastoid in a clinical setting.

Background:  Cervical vestibular evoked myogenic potentials (cVEMPs) are inhibitory myogenic responses that have commonly been elicited using a variety of stimuli. Yet the comparison of the effects of multifrequency tone bursts and narrow-band Claus Elberling chirps (NB CE-chirps) on cVEMPs has never been studied in homogeneous age groups.

Purpose:  The present study focused on comparing the effect of multifrequency NB CE-chirps and tone bursts on the various parameters of cVEMP responses in normal-hearing younger adults.

Research design:  A within-group study design was applied, and purposive sampling was utilized for the collection of the data sample.

Study sample:  The present study involved the elicitation of NB CE-chirp and tone burst-evoked cVEMPs across four-octave frequencies in 25 normal-hearing younger adults.

Results:  NB CE-chirp and tone burst evoked cVEMPs were found to have a 100% response rate for all frequencies except 4,000 Hz. Across frequencies, P1 and N1 latencies were seen to be significantly shorter for NB CE-chirps than tone bursts at 500 Hz and 1,000 Hz stimulation. No differences were seen in the P1N1 amplitudes and interaural asymmetry ratio between the two stimuli across all four-octave frequencies. Furthermore, we found a significantly higher number of ears tuned to NB CE-chirps than tone bursts at 500 Hz.

Conclusions:  Comparative differences in the latencies of cVEMP responses between and within stimuli could be due to the variation in stimuli duration. Also, the difference in amplitudes across stimulation frequencies might have resulted due to the predominance of saccular responses at lower mechanical resonance frequencies. Thus, the tuning was also seen at 500 Hz and was relatively higher for NB CE-chirps than tone bursts.

Background:  There is an increasing need to evaluate the quality of life of individuals who are hearing impaired. However, most of the generic "quality of life" questionnaires do not include communication-related questions. Recently, a new "Meaning of Life" (MOL) questionnaire was developed to measure quality of life based on everyday issues, enabling a comprehensive evaluation of tinnitus patients and cochlear implant users. A Mandarin Chinese version of this questionnaire for the Mandarin population is needed. Many of the existing Mandarin Chinese questionnaires currently in use are not effectively assessing hearing-related conditions.

Purpose:  We aimed to translate and validate the MOL questionnaire into Mandarin Chinese to make it applicable as a tool for measuring quality of life in patients with hearing loss or tinnitus.

Research design:  For this study, the original version of the MOL questionnaire was translated into the Mandarin Chinese language. A prospective cohort study was then performed on adults with hearing loss or tinnitus to preliminarily examine the reliability and validity of the Mandarin Chinese version.

Study sample:  A total of 206 Mandarin-speaking subjects with hearing loss or tinnitus were included in the study and divided into three groups according to their chief complaints: group B included patients suffering from both hearing loss and tinnitus (N = 113), group T contained patients with tinnitus alone (N = 49), and group H was composed of patients with hearing loss alone (N = 44).

Data collection and analysis:  The Mandarin version of the MOL (C-MOL) was administered to the participants. The reliability of the C-MOL was evaluated using Cronbach's α and item total correlation coefficients. Exploratory factor analysis was performed to examine the relationships among the questions. Correlations between the patient characteristics and total scores were tested.

Results:  The Cronbach's α coefficient of C-MOL was 0.921. Four factors were identified by exploratory factor analysis: (1) mental state and positive outlook; (2) friendship; (3) physical health; and (4) hearing and negative experience. The total scores of groups B, T, and H were 76.4 (standard deviation [SD] = 13.5), 81.3 (SD = 10.6), and 82.4 (SD = 12.5), respectively. The total score was correlated with the affected ears (r = 0.179, p < 0.05), age (r = 0.179, p < 0.05), hearing of the better ear (r = 0.188, p < 0.01), and educational background (r = 0.181, p < 0.01).

Conclusion:  The Mandarin Chinese version of the MOL questionnaire showed good reliability. It can be used to quantify the quality of life of patients with hearing loss or tinnitus.

Background:  The Hispanic population is growing, and Spanish is the second most spoken language in the United States. When individuals experience a hearing problem, culturally and linguistically responsive services represent an important part of person-centered care, contributing to wellbeing and intervention outcomes.

Purpose:  The purpose was to identify research in clinical audiology conducted with Spanish speakers to illuminate gaps and inform future research.

Research design:  A scoping literature review.

Data collection and analysis:  A database search was completed in January 2022. Included research was conducted in clinical audiology, had Spanish-speaking deaf or hard-of-hearing (DHH) adults/parents of a DHH child in the United States, Spanish language data collection, and published in English in a peer-reviewed journal. Studies were categorized by the area of audiology and a narrative description provided.

Results:  The search identified 655 articles. Following screening, 11 studies met the inclusion criteria and 1 article was identified from the reference lists of included articles for a total 12 articles. The articles were published between 1997 and 2021. Most studies were conducted with adults and a few were with parents of DHH children. Research was conducted in four areas: hearing loss experiences, hearing aid experiences, hearing screening, and communication.

Conclusions:  There is limited research with Spanish-speaking DHH individuals and parents of DHH children. There is an urgent need for future research to inform culturally and linguistically responsive clinical practice, and to provide evidence-based interventions for effective hearing health care management.

Background:  When performing oculomotor testing during standard videonystagmography (VNG), the vestibular system is not actively stimulated. Therefore, responses are generated from the cerebellum, brainstem, and oculomotor tract. Many patients seen for vestibular testing fall outside of the standard age norms, making it difficult to determine whether an abnormal finding is due to age or oculomotor dysfunction.

Purpose:  The purpose of this study was to further evaluate the effect of age on a standard clinical VNG oculomotor test battery consisting of saccades, smooth pursuit, and optokinetic (OPK) testing.

Research design:  This is a cross-sectional, between-group prospective study comparing oculomotor tests between age groups.

Study sample:  Twenty-one older adults between the ages of 60 and 90 years with no history of central or peripheral vestibular dysfunction were included in the study. Previously collected data from 29 children aged 4 to 6 years and 33 adults aged 20 to 60 years were also included.

Data collection and analysis:  Participants completed oculomotor testing using infrared goggles consisting of saccades, smooth pursuit, and OPK. Statistical analyses were completed using multivariate analysis of variance and analysis of variance and follow-up analysis when indicated.

Results:  Significant group differences were noted for saccade latency and speed, smooth pursuit gain, and OPK gain and speed. Children and older adults demonstrated longer saccade latencies compared with the controls, and older adults exhibited slower saccade speed than the controls and children. These results also indicated that smooth pursuit gain was reduced for children and older adults compared with controls, and gain decreased across all groups as frequency increased. Analyses of OPK results indicated older adults had reduced gain and speed compared with the children and control group.

Conclusions:  The findings of prolonged saccade latencies and reduced smooth pursuit gain in both children and older adults suggest possible cerebellar rather than attentional effects. However, other findings such as reduced saccade speed and reduced OPK gain were noted only in the older adults, which suggests oculomotor degeneration and/or insufficient coverage of the visual field during testing, respectively. These results also indicate the importance of age-specific normative data for use in clinical oculomotor testing.

Objective: This study investigates the potential correlation between in vitro fertilization (IVF) and hearing impairment in twins compared to naturally conceived twins.

Method: Analyzing data from 2416 twin infants born between 2019 and 2021. Analyze the pregnancy conditions and complications of mothers, the birth conditions of newborns, perinatal diseases, initial hearing screening results, and subsequent follow-up conditions.

Results: Our findings reveal that the incidence of hearing impairment in IVF-conceived twins is comparable to that in naturally conceived twins. Significant differences in low birth weight, preterm birth, respiratory distress syndrome, and hyperbilirubinemia were observed between infants who passed and referred the hearing screening (P ＜ 0.05). The IVF group exhibited a lower incidence of low birth weight (P < 0.05) and older maternal age (P < 0.05), while showing higher rates of placental abnormalities and placental abruption (P < 0.05). Notably, these distinctions did not translate into a significant impact on hearing impairment. Regardless of the method of conception, the following key factors contributing to hearing impairment in twins were identified: low birth weight, preterm birth, respiratory distress syndrome, and hyperbilirubinemia.

Conclusion: IVF technology does not exert specific effects on hearing impairment in twins, with perinatal complications being the primary influencing factors.

Background: Hearing loss significantly affects an individual's well-being, communication, social interaction, and quality of life. Cochlear implants serve as a viable management option. Given the variability in the impact of impairment, self-report measures are crucial for evaluating the perceived benefits of management options.

Purpose: The study aims to assess the reliability of the International Outcome Inventory for Cochlear Implants (IOI-CI) and establish normative cutoffs. This questionnaire evaluates patient's satisfaction with cochlear implants and contributes to the understanding of their experiences, addressing the increasing interest among cochlear implant clinicians.

Research design: The design relies on electronic medical databases within the Veterans Affairs (VA) and Department of Defense (DOD) systems. After identification of eligibility, recruitment was based on participants responding to mailed study documents. This research adopts a descriptive approach of the analysis of questionnaire responses as well as quantitatively evaluating the reliability.

Study sample: Forty-nine service members, Veterans, and their dependents, including 32 men and 17 women, participated in the study. The participants had a mean age of 68.0 years, with cochlear implants ranging from 6 months to 2 years post-initial stimulation. The majority had a unilateral cochlear implant with a hearing aid on the contralateral ear.

Data collection and analysis: Data collected involved mailing baseline study packets, including the IOI-CI questionnaire, to potential participants identified through medical databases. Participants indicated consent by returning the study packet. Follow-up packets were sent at a later time. Intraclass Correlation Coefficients (ICC) were utilized for test-retest reliability and Generalized Linear Models (GLM) for exploring the impact of clinical and demographic factors. Data were analyzed using R.

Results: The ICC revealed a good level of agreement (ICC=0.84) between baseline and follow-up assessments for the IOI-CI total score. The GLM did not identify significant factors influencing IOI-CI scores. Normative values were established, indicating total scores between 18 and 35 as within the normal range for this questionnaire.

Conclusions: The study contributes valuable insights into the reliability of the IOI-CI and establishes normative cutoffs, aiding clinicians in assessing cochlear implant users' experiences and satisfaction.
