Resumen
Objetivo

En este trabajo se analizan la función vestibular y grado de discapacidad en dos poblaciones de pacientes con historia congruente de vértigo posicional y resultado dispar en la maniobra de Dix-Hallpike.

Material y Métodos

Se estudiaron 114 pacientes con vértigo posicional. En 65 el Dix-Hallpike fue positivo (DH+) y en 49 fue negativo (DH-). Se realizó prueba calórica y se determinó el grado de discapacidad vestibular utilizando diferentes cuestionarios.

Resultados

Los pacientes del grupo DH+ manifestaron un mayor nivel de discapacidad en la subescala física del DHI y una percepción de mayor deterioro en su calidad de vida. Los pacientes del grupo DHmanifestaron un mayor nivel de discapacidad en la subescala emocional del DHI.

Conclusiones

Descartado el fenómeno de fatigabilidad del nistagmo en el VPPB, los pacientes del grupo DH- no representan una forma menor del VPPB

Abstract
Objective

The aim of this work is to analyze the vestibular function and level of disability in two populations of patients with positional vertigo but with differents results in the Dix- Hallpike test.

Material and Methods

114 patients were assessed. In 65 the Dix-Hallpike test was positive (DH+) and in 49 negative (DH). The caloric test was performed as well as the assessment of disability with the pertinent questionnaires for vestibular disability.

Results

Patients in the DH+ group showed a higher level of disabilty in the physical subscale of the DHI and a higher perception of a deteriorated quality of life. Patients in the DH- group showed a more severe disability in the emotional subscale of the DHI.

Conclusions

Once the phenomenon of nystagmus fatigability is ruled out, patients with positional vertigo and DH- must not be considered a minor form of positional vertigo.
