The ability to maintain balance is significantly compromised in children with visual impairment and has higher risks of falls than the normal sighted children. Children with visual disability reported delayed motor dexterity such as eye-hand coordination, gross and fine motor control involving struggle in gait procurement and postural control. Vestibular rehabilitation is  the relevant therapy to restitute for maintaining postural control in the absence of visual information. This study aimed to find the effect of vestibular rehabilitation on postural stability in children with visual impairment. \u0000Methods: A quasi-experimental study was done in pre and post-test type design on 30 boys in the age group of 7-16 years’ children with visual impairment.

We investigated the effect of integrating alternate auditory attention (ALAUDIN©) tasks with White Noise (WN) and its reliability using contralateral suppression of Transient Evoked Otoacoustic Emission (TEOAE). \u0000Methods: This study was conducted at the Audiology Clinic, Universiti Kebangsaan Malaysia, with fifty normal-hearing adults. All subjects underwent standard audiological testing to ensure normal hearing, middle ear, and cochlear function. Contralateral suppressors with and without attention tasks were delivered randomly to the non-test ear while simultaneously measuring TEOAE amplitude in the test ear to investigate the effect of auditory attention on OHC electromotility. Suppressors with and without attention refer to the combination of a 1000 Hz tone and speech stimulus embedded in WN and WN alone, respectively. Subsequently, the difference in TEOAE amplitude during the presence and absence of suppressors was calculated, and thus suppression magnitude was determined. \u0000Results: Intraclass correlation revealed that 4 suppressors produced high reliability. In paired sample t-tests, the tasks significantly reduced the amplitude of the TEOAE in the right ear compared to the left ear (p<0.05). However, the suppression magnitude did not differ significantly between ears (p>0.05). Descriptively, females showed greater TEOAE suppression. \u0000Conclusion: This study demonstrated that directing ALAUDIN© tasks to one ear can affect OHC electromotility, as evidenced by TEOAE amplitude changes, but it did not impact the overall suppression magnitude. Additionally, it hinted at potential gender differences in TEOAE suppression, warranting further investigation. \u0000  \u0000Keywords: Suppression; otoacoustic emissions; efferent pathway; auditory attention","PeriodicalId":34089,"journal":{"name":"Auditory and Vestibular Research","volume":null,"pages":null},"PeriodicalIF":0.5,"publicationDate":"2024-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140489502","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Vestibular Rehabilitation Therapy (VRT) is an effective treatment for people with this disease. This study aimed to determine effect of VRT on the daily life aspects of military men with PPPD. \u0000Methods: In this clinical trial, participants were 56 military men with PPPD. They underwent VRT that included exercises for gaze stabilization, adaptation, and habituation. The impact of balance problems caused by PPPD on different physical, emotional, and functional aspects of daily life was evaluated using the Dizziness Handicap Inventory (DHI) before and one month after the intervention. \u0000Results: There was a significant decrease in functional, emotional, physical, and total scores on the DHI after VRT (p<0.001). The DHI scores at baseline showed a moderate handicap (48.64%) which decreased to a mild handicap (24.53%) after VRT. The lowest score at baseline was related to the functional aspect, which showed the highest improvement after VRT. \u0000Conclusion: The VRT can improve all aspects (physical, emotional, and functional) of daily life in military men with PPPD and diminishes the severity of symptoms. Therefore, this treatment can be used as a suitable treatment for these patients. \u0000IRCT Registration Number: IRCT20230520058237N1 \u0000  \u0000Keywords: Persistent postural-perceptual dizziness; dizziness handicap inventory; vestibular rehabilitation; military \u0000 ","PeriodicalId":34089,"journal":{"name":"Auditory and Vestibular Research","volume":null,"pages":null},"PeriodicalIF":0.5,"publicationDate":"2023-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138600347","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The imbalance in the chemical composition of otoconia can make people susceptible to Benign Paroxysmal Positional Vertigo (BPPV). The primary outcome was to compare serum magnesium levels in BPPV patients with controls. The Ca/Mg ratios in participants are also recorded and analyzed in the present study. \u0000Methods: In this case-control study, we measured the serum Mg, Ca, and vitamin D in BPPV patients and age-, sex-matched subjects without BPPV. The results were adjusted for Ca, vitamin D, hypertension, and body mass index. \u0000Results: A total of 123 BPPV patients participated in this study. The mean Mg value was higher in patients than controls (2.01 vs. 1.95 mg/dL, p=0.030).

Various studies recommend auditory processing training to improve auditory processing difficulties in CI users. The aim of the present study was to evaluate phoneme processing difficulties in CI users and to investigate the efficacy of the Persian version of the Phonemic Synthesis Program (P-PSP) in improving phonological abilities in this population. \u0000Methods: A total of 28 prelingually hearing-impaired children aged 8–12 who underwent unilateral (right ear) cochlear implantation were included in this study. They were divided into experimental and control groups. The P-PSP was implemented on the experimental group, and the results were analyzed over three phases: baseline, intervention, and follow- up. \u0000Results: The present study’s results indicate that P-PSP training is suitable for CI children, particularly for the DEC subcategory.
