Over-the-counter (OTC) and self-fitting strategies have emerged to improve accessibility, allowing users to select and adjust their devices independently. However, concerns remain that reducing professional involvement may compromise electroacoustic accuracy, speech-in-noise outcomes, and overall patient satisfaction. <b>Methods:</b> A comprehensive literature search across PubMed, Web of Science, CENTRAL, Scopus, and Embase was conducted up to 1 June 2026. Parallel-group and crossover randomized controlled trials (RCTs) comparing self-fitting with professional-fitting were included. The primary outcome was patient-reported hearing benefit. Standardized mean differences (SMDs) and risk ratios (RRs) were pooled using a random-effects model. <b>Results:</b> Seven RCTs involving 1092 participants were included. The analysis revealed no statistically significant difference between self-fitting and professional-fitting strategies regarding patient-reported hearing benefit (SMD: 0.01, 95% CI [-0.44, 0.46], <i>p</i> = 0.97, I² = 89.2%, very low certainty of evidence). Similarly, no significant differences were observed across secondary outcomes, including speech-in-noise performance (SMD: 0.11, 95% CI [-0.25, 0.47]; <i>p</i> = 0.55), hearing loss (<i>p</i> = 0.12), hearing-aid satisfaction (<i>p</i> = 0.31), device adherence (<i>p</i> = 0.65), or the need for follow-up adjustment (RR: 0.46, 95% CI [0.12, 1.71]; <i>p</i> = 0.25). Safety outcomes were sparse and did not demonstrate a statistically significant difference between the fitting approaches; however, the evidence was imprecise and inconclusive. <b>Conclusions:</b> Self-fitting hearing aids showed no clear differences from professional best-practice fitting across several patient-reported and functional outcomes in adults with uncomplicated mild-to-moderate hearing loss. However, the certainty of evidence was very low because of risk of bias, substantial heterogeneity, imprecision, and the small number of trials. These findings are therefore hypothesis-generating and suggest that well-designed self-fitting pathways may have potential as an accessible alternative for selected users, but larger, rigorous, and longer-term trials are needed before broader clinical implementation can be recommended.</p>","PeriodicalId":44133,"journal":{"name":"Audiology Research","volume":"16 5","pages":""},"PeriodicalIF":1.7,"publicationDate":"2026-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13600142/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149031813","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

MST and DTT showed a positive association at T0 (Pearson r = 0.833, 95% CI 0.497-0.952), whereas no clear association was observed at T1 (r = 0.074, 95% CI -0.583-0.672).

The accurate diagnosis of BPPV requires high-quality physician training and knowledge of the advantages and disadvantages of different diagnostic methods. Most studies focus on a limited number of diagnostic approaches; the purpose of this review is to consolidate and systematize the available information on the wide range of existing methods. This review includes comparative descriptions of the clinical utility of 12 different techniques used to diagnose BPPV. The diagnosis of BPPV relies primarily on a thorough analysis of clinical history and the professional application of positional tests (primarily the Dix-Hallpike and the Pagnini-McClure maneuvers). Several methods can be used to enhance the efficiency of positional testing: rotary chair, electronystagmography (ENG), videonystagmography (VNG), and potentially artificial neural networks for the analysis of VNG results. The VEMP (vestibular evoked myogenic potential) technique, vestibular caloric testing, the video head impulse test, computerized posturography, and CT and MRI of the head are all useful auxiliary methods for the differential diagnosis of BPPV in complex cases. When selecting diagnostic approaches, it is important to consider the balance between resource and time expenditure and diagnostic accuracy.

We explicitly distinguish established evidence from interpretations and model-derived hypotheses. Recent human and nonhuman primate work on internal models, active self-motion, and multisensory recalibration is integrated with developmental and clinical evidence. The framework is then tested conceptually across congenital and acquired vestibular loss, altered gravity, and aging. Its proposed novelty lies not in Bayesian inference or internal models themselves, but in combining phylogenetic constraints, prenatal calibration, a qualitative transition at birth, time-dependent plasticity, and life-span context switching within a single developmental account. Finally, we operationalize the model through measurable predictions involving VOR adaptation, sensory-weighting coefficients, anticipatory postural responses, context-specific readaptation, and postural stability.
