The profiles of malay muslims with vestibular disorders and the outcome of vestibular rehabilitation.

Abstract
Those who are diagnosed with chronic vestibular disorders are anticipated to
experience disturbing vestibular symptoms when pursuing their daily life activities. In the
present study, it was of interest to know the specific difficulties faced by Muslims when
performing their daily tasks (including solat) and whether the conventional vestibular
rehabilitation would be effective in reducing the symptoms. This is a mixed-design study
with three consecutive phases. In the first phase, triggering and/or worsening factors to
vestibular symptoms were determined. In the subsequent phases, a mixed-convergent
study design was employed, i.e., quantitative (VHIT, cVEMP and MyVRBQ) and
qualitative (in-depth interview) methods. Of 91 respondents, 68% reported that their
symptoms were triggered by body and head movements. Nearly half of them reported at
least one prayer movement triggered and/or worsened their symptoms. In the second phase
of the study, despite normal findings from VHIT and cVEMP (except for P13 and N23
latencies), MyVRBQ showed that the participants were affected by the symptoms.
Content analysis unveiled five content areas: 1) Common symptoms, 2) Effects on general
activities, 3) Effects on performing solat, 4) Conditions that may exacerbate and/or
provoke vestibular symptoms, 5) Compensatory strategies to overcome and/or hinder
from having the symptoms. Following rehabilitation, significant reductions in MyVRBQ
scores were seen in all categories (as early as two weeks). Two content areas were
discovered: 1) Improvements in general activities, and 2) Improvements in solat. While
the objective assessments (VHIT and cVEMP) were insensitive, the occurrence of the
symptoms and the benefit of the rehabilitation were clearly shown by MyVRBQ. The
content analysis was able to discover other important aspects missed to be covered by the
quantitative assessments (including the ability to perform solat before and after the
rehabilitation). The study findings would be useful to clinicians in providing optimum
services to Muslim patients with chronic vestibular disorders.
