Efectividad de los ejercicios de Brandt-Daroff en pacientes con vértigo posicional paroxístico benigno / Effectiveness of the Brandt-Daroff Exercises in Patients with Benign Paroxysmal Positional Vertigo

El vértigo posicional paroxístico benigno se caracteriza por episodios breves pero intensos de vértigo con los cambios de postura, en su tratamiento pueden utilizarse ejercicios específicos. Objetivo: Evaluar la efectividad de los ejercicios de Brandt-Daroff en el tratamiento del vértigo posicional paroxístico benigno y su relación con los grupos de edades y sexo. Métodos: Se aplicó un método descriptivo, con una muestra de 62 pacientes adultos que presentaban diagnóstico de vértigo paroxístico posicional benigno. Se utilizó la escala dicotómica con presencia o ausencia de vértigo, al inicio y final del tratamiento con estos ejercicios. Se analizaron las variables: edad, sexo y mejoría clínica de la enfermedad. Para el análisis estadístico se utilizó la Prueba de homogeneidad λ2 con un nivel de significación de ά 0,05. Resultados: Se observó evolución favorable para el tratamiento de este trastorno mediante los ejercicios de Brandt-Daroff con el 87,09 por ciento en la eliminación del vértigo a las 7 sesiones de tratamiento, un 90 por ciento de efectividad en edades de 25 a 59 años y el 76,19 por ciento del sexo femenino, de ellas el 91,66 por ciento no presentó vértigos a final del tratamiento. Conclusiones: Se señala la efectividad de los ejercicios de Brandt-Daroff en el tratamiento del vértigo paroxístico posicional benigno con diferencias estadísticamente significativas en comparación con el tratamiento convencional. Mayor efectividad en edades de 25 a 59 años y el predominio del sexo femenino(AU)

Benign paroxysmal positional vertigo is characterized by brief but intense episodes of vertigo with changes in posture. Specific exercises can be used for its treatment. Objective: To evaluate the effectiveness of Brandt-Daroff exercises in the treatment of benign paroxysmal positional vertigo and its relationship with age and sex groups. Methods: A descriptive method was applied, with a sample of 62 adult patients who had a diagnosis of benign positional paroxysmal vertigo. The dichotomous scale with presence or absence of vertigo was used at the beginning and at the end of treatment with these exercises. The variables analyzed were age, sex, and clinical improvement of the disease. For statistical analysis, the chi-square homogeneity test was used with a significance level of 0.05. Results: A favorable evolution was observed for the treatment of this disorder by means of the Brandt-Daroff exercises, with 87.09 percent in the elimination of vertigo after seven treatment sessions, 90 percent effective in ages 25-59 years, and 76.19 percent corresponding to the female sex, of which 91.66 percent did not present vertigo at the end of treatment. Conclusions: The effectiveness of the Brandt-Daroff exercises is highlighted for the treatment of benign positional paroxysmal vertigo, with statistically significant differences compared to conventional treatment. Greater effectiveness in ages 25-59 years and the predominance of the female sex(AU)

Analysis of the diagnosis maneuver of lateral semicircular canal benign positional paroxysmal vertigo and observation of the otolith movement using physical engine / 解剖学报

Objective To analysis the diagnosis maneuvers of lateral semicircular canal benign positional paroxysmal vertigo (BPPV) and to explore the diagnostic mechanism. Methods The three-dimensional BPPV labyrinth model was established based on the physical engine. The otolith in different positions of the lateral semicircular canal was set up. The otolith movement in different positions during the horizontal roll test was analyzed, and the induced nystagmus could be inferred. Results Horizontal roll test nystagmus manifestations were diverse, including bilateral ageotropic nystagmus, which could be judged as otolith in ampullary and crista, and weak side of nystagmus was the affected side; bilateral geotropic nystagmus could be judged as otolith in the long arm of the lateral semicircular canal, and strong side of nystagmuss was the affected side; Ageotropic nystagmus in one side and geotropic nystagmus in another side, considering otolith in ampullary of long arm. The horizontal roll test may restore otolith to utricle and reduce the sensitivity of the diagnostic tests. The result of 10 repetitions were consistent. Conclusion Sixty degree horizontal roll test effectively corrects the defects of 90 degree horizontal roll test. The analysis of diagnostic tests based on the physical engine is of great significance for us to understand the diagnostic mechanism of BPPV in the lateral semicircular canal and to improve and innovate diagnostic maneuver.

A Case of Drastic Improvement in a 43 Year Old Male with Severe Refractory Incapacitating Vertigo.

Introduction: Vertigo is a common and distressing complaint seen in primary care. It can be due to central or peripheral causes, which should be determined right at the outset. In some cases, the vertigo is transient and easily manageable while in others it can be more troublesome and difficult to treat. Case: A 43 year old male presented with episodes of severe vertigo and vomiting progressively increasing since six months. Despite multiple consultations, complete work up and treatment with the standard therapy for suppressing vertigo, his symptoms persisted. On history and examination, it seemed to be a case of Ménière’s Disease and we started him on specific therapy. The patient showed marked improvement within a week and continued to do so at the end of three months despite stopping all treatment. Conclusion: Identification of the cause of vertigo, multidisciplinary management and specific treatment, rather than just vestibular suppressants, are paramount in managing a case of vertigo.
