RESUMO
OBJECTIVES: To examine the effects of Cawthorne-Cooksey exercises on individuals with vestibular dysfunction symptoms. METHODS: Systematic search was conducted using PubMed, EBSCO SCOPUS, Web of Science, and Google Scholar from inception to March 2023. The Physiotherapy Evidence Database (PEDro) scale was employed to evaluate the risk of bias in the included studies. RESULTS: Ten randomized controlled trials met the eligibility criteria. In total, 610 participants, 41.31 % of whom were men were included in this review. The PEDro scale scores ranged from 6 to 8 with a median of 6.5/10. Our findings revealed improvements in patients' vestibular dysfunction symptoms after Cawthorne-Cooksey exercises and other conventional interventions. CONCLUSIONS: The initial findings showed that Cawthorne-Cooksey exercises are not superior to other concurrent vestibular rehabilitation interventions in improving vestibular dysfunction symptoms. Additional trials with long-term follow-ups are strongly recommended to understand the impacts of Cawthorne-Cooksey exercises on vestibular dysfunction symptoms.

Una propiedad fundamental de los sistemas sensoriales es su capacidad para detectar estímulos novedosos en el entorno. El sistema nervioso posee neuronas que disminuyen su respuesta a los estímulos sonoros que se repiten a lo largo del tiempo y otras neuronas que aumentan su frecuencia de disparo ante estímulos novedosos, siendo la diferencia entre ambas respuestas conocida como adaptación-específica a estímulos. En las últimas décadas, se ha propuesto que el cerebro establece, continuamente, predicciones de los estímulos novedosos y del entorno basándose en sus experiencias previas y en modelos de representación internos, teoría denominada codificación predictiva. En esta revisión, abordaremos algunos conceptos de la adaptación-específica a estímulos y codificación predictiva, centrándonos principalmente en el sistema auditivo. Por último, propondremos una explicación teórica basada en el marco de la codificación predictiva para algunas disfunciones neuropsiquiátricas, auditivas y vestibulares.
A fundamental property of sensory systems is their ability to detect novel stimuli in the environment. The nervous system possesses neurons that decrease their response to sound stimuli that are repeated over time and other neurons that increase their firing rate to novel stimuli, the difference between the two responses being known as stimulus-specific adaptation. In recent decades, it has been proposed that the brain continuously makes predictions of novel stimuli and the environment based on its previous experiences and internal representational models, a theory called predictive coding. In this review, we will address some concepts of stimulus-specific adaptation and predictive coding, focusing mainly on the auditory system. Finally, we will propose a theoretical explanation based on the predictive coding framework for some neuropsychiatric, auditory, and vestibular dysfunctions.

OBJECTIVE: The objective of the work was to study the clinical and electrophysiological disorders in vestibular and acustic dysfunctions in clean up workers of Chornobyl accident depending on the dose and duration of action of ion izing radiation, the peculiarities of determined effects for 30 years after the accident. MATERIALS AND METHODS: The standard clinical and electrophysiological examinations of vestibular and acoustic ana lyzers functions were conducted in 7812 males' clean up workers including 325 persons selected for prolonged stud ies in 1986 2015. The mathematical methods of analysis were carried out using the software package SYSTAT, EPICURE and EGRET. RESULTS: Vestibular dysfunction and acoustic dysfunction according the central type of progressive development of inhibitory processes in the brain stem, subcortical and cortical structures of vestibular and acoustic analyzers were determined. The dependence of changes in these structures on the dose and duration of ionizing radiation effect was defined. The regularities of determined radiation effects in correlation with the formation of organic cerebrovascu lar pathology in the clean up workers in remote post accident years that are consistent with neurophysiological, MRI and other examinations confirmed with correlation analysis were established. CONCLUSIONS: It was registered that the vestibular and acoustic dysfunctions in the clean up workers were manifest ed by the clinical and electrophysiological changes at the level of central structures in the studied analyzers, which indicate the parallelism of common mechanism of determined radiation effects already at a dose of 0.20 Gy, and also their dose dependency in dynamics of 30 post accidental years. It was established that vestibular dysfunction in the clean up workers is clinically early manifested, and the electroacoustic and electrophysiological changes in a case of normal hearing are evidence of preclinical inhibitory processes in the brain stem, subcortical and cortical structures of acoustic analyzer in the early post accident years. The features of the clinical course of vestibular and acoustic dysfunctions in long term monitoring of short term effects of ionizing radiation in high doses in the group of the clean up workers who have acute radiation sickness, and the manifestation of change is greater and accelerated in time under long term IR effect, than the relatively short term ones in similar small doses in distant years. Significant increase of hearing disorders by type of presbyacuzis precox in the respective age categories, which is one of the symptoms of their premature their aging was studied in clean up workers.
