RESUMEN
OBJECTIVE: The aim of this study was to investigate the effect of a visual cognitive additional task on balance performance in young adults with hearing aids (HAs). METHOD: Twenty young adult HA users and 20 controls were recruited for the study. Participants were asked to stand on a force plate using computerized dynamic posturography and perform a Sensory Organization Test (SOT) as a balance task under single-task (ST) and dual-task (DT) conditions. The DT condition involved performing a visual cognitive task (Backward Digit Recall) while maintaining balance. Balance performance was measured using equilibrium scores under four different conditions. RESULTS: The results showed that SOT scores of HA users decreased significantly in the DT compared to the ST (p of Condition 1: < .001; p of Condition 4: < .001; p of Condition 6: = .001). HA users' SOT scores in the DT condition were statistically significantly lower than controls (p of Condition 1: < .003; p of Condition 4: < .009; p of Condition 6: = .004). This suggests that the presence of a visual cognitive additional task has a negative impact on balance performance in young adults with HAs. CONCLUSIONS: These findings highlight the importance of considering the impact of cognitive tasks on balance performance in young adults with HAs. Further studies should investigate the specific needs of hearing loss patients in multitasking conditions, including age, degree of hearing loss, and cognitive ability, to develop effective interventions to reduce the risk of falls.

BACKGROUND: Benign paroxysmal positional vertigo (BPPV) patients may experience balance problems in various environmental conditions other than positional dizziness. Therefore, there is a need to investigate the postural control abilities and the ability to use sensory inputs in BPPV patients in different conditions. OBJECTIVE: The aim of this study was to examine the postural control performance of middle-aged adult BPPV patients in easy and difficult balance tasks, the effect of vestibular stimulation on the maintenance of balance, and the risk of falling, by posturographic evaluation in various conditions. METHOD: A total of 26 patients diagnosed with posterior canal BPPV and 26 controls were included in the study. Sensory Organization Test (SOT), Vestibular Stimulation Test (VST), and fall risk assessment (FRA) were applied to the participants, respectively. RESULTS: Significant difference was observed in SOT medio-lateral (ML) plane in Conditions 2 and 5 (p < .05). A significant difference was observed in the vestibular score in the SOT ML plane. No significant difference was observed in VST test scores (p > .05). In the FRA test, a significant difference was observed in the energy and gain parameters in the anterio-posterior plane (p < .05). CONCLUSIONS: The current study examined postural control abilities of patients with BPPV in extensive external conditions and in both planes, using various sensory perturbations and stimulation. It was thought that while BPPV patients were in the active phase of the disease, their postural control skills in the ML plane decreased and they might be at risk of falling.

PURPOSE: The main purpose of the study is to investigate whether the presence of residual hearing before cochlear implantation has an effect on temporal pattern recognition skills and musical perception in adults. METHOD: The study included adults with cochlear implants who were between the ages of 20 and 45 years. Adults with cochlear implants were divided into two groups: absent (n = 20) and available (n = 20) groups according to residual hearing before implantation. Frequency Pattern and Duration Pattern tests were applied to evaluate temporal pattern recognition, and the "Music-Related Quality of Life Questionnaire" was applied to evaluate musical perceptions. RESULTS: There were no statistically significant differences between the groups in terms of cochlear-implanted hearing thresholds and speech recognition scores, musical perception, and musical activities, according to their residual hearing. On the other hand, the frequency and duration pattern recognition skills were statistically significantly better in adults with residual hearing. Also, statistically significant correlations were obtained in terms of temporal skills and musical perception subskills. CONCLUSIONS: The presence of residual hearing before cochlear implantation may affect temporal auditory processing skills. It is concluded that the integration of cochlear implants may affect temporal processing skills in adults as well as quality of life. It is recommended that experts be aware of this issue and pay attention to residual hearing.

PURPOSE: The aim of this study was to examine whether the medial olivocochlear hearing system functions, the high frequency hearing thresholds and speech discrimination in noise performance can guide us in assessing the risk of hearing loss among violinists. It is aimed to investigate possible hearing damage that is not reflected in pure tone hearing thresholds in violinists. METHODS: The participants (n = 50) who have normal hearing and the ages of 18-30 were included in this study in two groups: violinists and controls who are unrelated to music. High frequency audiometer, auditory figure ground test (AFG) for speech discrimination in noise performance, Distortion Product Otoacoustic Emission (DPOAE) and contralateral suppression on DPOAE for medial olivocochlear system function tests were applied to all participants as well as routine audiological tests. RESULTS: The high frequency hearing thresholds were obtained higher in violinists compared to the controls. In violinists, the AFG test scores and the suppression amount at 1 kHz were lower than the controls. In addition, DPOAE responses at 4-6 kHz were obtained lower in violinists (p < 0.05). CONCLUSION: The reason for high frequency hearing loss, decreased DPOAE response amplitudes, and poor medial olivocochlear function in violinists can be explained by the long-term exposure to high-level noise caused by the violin, one of the closest musical instruments. Routine and comprehensive audiological follow-up is crucial for musicians.

Purpose The purpose of this study was to investigate the possible effects of smartphone usage in the biomechanical balance system. Method Twenty-five healthy young adults (10 men, 15 women) between the ages of 18 and 25 years without balance problems were included in the study. Sensory organization, adaptation, rhythmic weight shift, and functional limitation tests (unilateral stance, sit to stand, walk across, tandem walk, step quick turn, step up down, forward lunge) have been applied. Results Significant results were obtained in parameters of sensory organization, tandem walk, walk across, and unilateral stance tests (p < .05). Conclusion The effects of using smartphones on postural control and balance in different circumstances, such as standing and walking, must be comprehensively determined to prevent accident.

Background/aim: Autoimmune diseases are a remarkable issue for researchers due to their adverse effects on the auditory system, but for primary Sjögren's syndrome (pSS) there is little research on the comprehensive audiological findings in literature. The main objective of this study was to investigate the medial olivocochlear efferent functions of subjects with pSS and to examine the audiological findings. Materials and methods: The study included 36 subjects with pSS and 36 healthy subjects. All the subjects underwent testing including pure tone, speech, and high frequency audiometry; tympanometry and acoustic reflexes; distortion product otoacoustic emissions (DPOAE); and suppression of DPOAE. Results: The hearing thresholds of the pSS group were higher than those of the control at all frequencies (P < 0.001). Minimal to mild sensorineural hearing loss was observed in 52.77% of all the subjects with pSS. Additionally, all of the subjects had type A curve tympanograms, but the static compliances of the pSS group were lower and the acoustic reflex thresholds were higher than in the control (P < 0.001). In suppression levels of DPOAE, no statistically significant difference was found between the groups (P > 0.05). Conclusion: The study indicates that because of obtaining normal suppression levels in DPOAE, the medial olivocochlear efferent system is functional in pSS. However, there is a need for more tests, including auditory brainstem response, to evaluate the afferent auditory system in pSS.
