RESUMEN
Abstract Introduction: The Epley maneuver is applied in the treatment of benign paroxysmal positional vertigo, the BPPV. However, dizziness and balance problems do not improve immediately after the treatment. Objective: In this study, the effectiveness of the head-shaking maneuver before the Epley maneuver was investigated in the treatment of BPPV. Methods: Between March 2020 and August 2020, ninety-six patients with posterior semicircular canal BPPV were analyzed prospectively. The patients were divided into two groups: patients who underwent the Epley maneuver only in the treatment (Group 1) and patients who underwent the Epley maneuver after the head-shaking maneuver (Group 2). The results of the Berg balance scale and dizziness handicap index were evaluated before the treatment and at the first week after the treatment. Results: The improvement in functional, emotional, and physical dizziness handicap index and Berg balance scale values after the treatment was found to be statistically significant in both groups. It was determined that the change in functional and physical dizziness handicap index and Berg balance scale values of the patients in Group 2 was statistically higher than those in Group 1. Although, the change in emotional dizziness handicap index values in Group 2 was higher than those in Group 1, no statistical significance was found between the groups. Conclusion: As a result of our hypothesis, we think that in the treatment of posterior semicircular canal BPPV, the otoliths adhered to the canal can be mobilized by the head-shaking maneuver, and this will contribute to the increase of the effectiveness of the Epley maneuver.
Resumo Introdução: A manobra de Epley é aplicada no tratamento da vertigem posicional paroxística benigna (VPPB). Entretanto, a tontura e os problemas de equilíbrio não melhoram imediatamente após o tratamento. Objetivo: Investigar a eficácia da manobra de balançar a cabeça antes da manobra de Epley no tratamento da VPPB. Método: De março de 2020 a agosto de 2020, 96 pacientes com VPPB de canal semicircular posterior foram analisados prospectivamente. Os pacientes foram divididos em dois grupos: pacientes que foram submetidos apenas à manobra de Epley no tratamento (Grupo 1) e pacientes que foram submetidos à manobra de Epley após a manobra de balanço da cabeça (Grupo 2). Os resultados da escala de equilíbrio de Berg e do dizziness handicap index foram avaliados antes do tratamento e na primeira semana após o tratamento. Resultados: A melhoria nos valores funcionais, emocionais e físicos do dizziness handicap index e da escala de equilíbrio de Berg após o tratamento foi estatisticamente significante em ambos os grupos. Foi determinado que a alteração nos valores funcionais e físicos do dizziness handicap indexe da escala de equilíbrio de Berg dos pacientes do Grupo 2 foi significantemente maior do que aqueles do Grupo 1. Embora a alteração nos valores do dizziness handicap index emocional no Grupo 2 tenha sido maior do que no Grupo 1, não houve significância estatística entre os grupos. Conclusão: Como resultado de nossa hipótese, acreditamos que no tratamento da VPPB do canal semicircular posterior os otólitos aderidos ao canal podem ser mobilizados através da manobra de balanço da cabeça, o que contribuirá para o aumento da eficácia da manobra de Epley.
RESUMEN
BACKGROUND: It has been reported worldwide that patients with a diagnosis of COVID-19 usually suffer a loss of smell and taste. In this study, we aimed to evaluate the relationship between the severity of the disease and the loss of smell and taste. In addition, we evaluated patients' smell and taste functions after recovery. METHODS: Between March and May 2020, 418 patients diagnosed with COVID-19 were divided into 3 groups: home-quarantined, hospitalized, and intensive care patients. The disease, smell, and taste functions of patients were evaluated with visual analog scores before diagnosis of COVID-19, during the disease, and fourth week after recovery. The types of smell loss and types of taste flavor loss occurring during the disease were questioned. RESULTS: In all 3 groups, changes in smell and taste loss during the disease were statistically detected (Pâ=â0.001). The smell loss rates determined in groups 1 to 3 were 45%, 43.7%, and 31.2%, respectively. The taste loss rates determined in groups 1 to 3were 46.6%, 32.1%, and 31.2% respectively. The rate of patients with a total recovery of smell loss in groups 1 to 3 were 95.5%, 93.7%, and 100%, respectively (Pâ=â0.768). The rate of patients with a total recovery of taste loss in groups 1 to 3 were 97.1%, 91.4%, and 100%, respectively (Pâ=â0.423). CONCLUSION: COVID-19 causes significant loss of smell and taste in patients. The loss of smell and taste does not correlate with the severity of COVID-19 disease. The loss of smell and taste improves at a high rate after the disease.
