Background: The broad range of vestibular tests used to diagnose labyrinth diseases allows for a functional assessment of the vestibular system. Among the many tests performed, the caloric test is considered the gold standard by providing an objective measurement of the vestibular function for each labyrinth. Objective: to correlate the different types of dizziness with the caloric test result. Methods: a descriptive study was performed based on the previous records of vestibular tests performed on patients with body balance disorders evaluated at Audiology Service between 2000 and 2020. The variables evaluated were sex, age, hearing loss, tinnitus, and caloric test result. Results: the sample was composed of 892 patients, 654 (73.4%) women, and 238 (26.6%) men. Normal results were obtained for 57.4% (N = 514) of the individuals, while peripheral disease 40.1% (N = 357), and central disease 2.5% (N = 21) accounted for the remaining. Complaint of vertigo was not common in central disorders ( P = .02; OR = 0.17) and instability was associated with bilateral vestibular weakness ( P = 0.02; OR = 5.92). Vertigo associated with tinnitus and/or hearing loss was more frequent in the caloric test with peripheral abnormality ( P = 0.008). Conclusion: complaints of vertigo associated with tinnitus and/or hearing loss must be directed for clinical observation of unilateral peripheral lesion and instability to central disease or bilateral peripheral lesion.
Virtual Reality is cogitated as one of the most favorable and challenging technologies applied in health sciences. Its use has been integrated in vestibular rehabilitation for the management of balance conditions, founded on mechanisms related to neuronal plasticity of the central nervous system. Dizziness is one of the most common symptoms after a concussion in sports and can be an issue related to a long return to play. Virtual reality may be a beneficial method for rehabilitation for athletes with dizziness after concussion. However, no studies have critically reviewed the scientific evidence in this regard. The objective was to conduct a systematic review on the effectiveness of virtual reality as a rehabilitation strategy for athletes after a concussion. A systematic review of the electronic databases Cochrane Collection, Consumer Health Complete, Oxford Journals, PubMed, Science Direct, and SPORTDiscus was conducted to identify studies related to the effect of virtual reality after a concussion in athletes. The search timeframe ranged from January 1990 to December 2019. The search resulted in the identification of 3 randomized controlled trials (RCTs) and 7 non-RCT studies. None of the studies were specific associated with athletes with dizziness after a concussion. Specific studies are necessary to establish the application that may respond optimally to the treatment of concussions associated with balance problems.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
