Multiple Sclerosis Clinical Trial
Official title:
Epley Manoeuvre for Posterior Semi-circular Canal Benign Paroxysmal Positional Vertigo in People With Multiple Sclerosis: Protocol of a Randomized Controlled Trial
Vertigo, dizziness and control postural disturbance are one of the most disabling symptoms in Multiple Sclerosis. These could be caused by a peripheral or central vestibular disorder. Although, central vestibular damage is more prevalent, peripheral vestibular disturbance aetiology is significantly common in this disease. Within peripheral vestibulopathy, benign paroxysmal positional vertigo is the most common syndrome. Impairments of posterior semi-circular canals in benign paroxysmal positional vertigo represent among the 60-90 % of the cases. Gold standard treatment in this syndrome is the canalith repositioning procedure, called Epley manoeuvre. This manoeuvre has been deeply investigated in previous studies for participants who only suffer from benign paroxysmal positional vertigo. Any randomized clinical trials have been carried out to assess the effectiveness of Epley manoeuvre. However, a retrospective research and a case study reported encouraging results for the resolution of posterior semi-circular canal benign paroxysmal positional vertigo, through the Epley manoeuvre. The main objective of the study is to assess the effectiveness of the Epley Manoeuvre for the improvement of the benign paroxysmal positional vertigo of participants with multiple sclerosis, compared to a passive control group.

Primary | Changes in the conversion of a positive to a negative Dix Hallpike Test | The performance of Dix Hallpike Test consists on a participant sit on a table and the head is turn 45 degrees towards the tested side. Once this position is stablished, the evaluator is going to laid back the participant in a quick movement sum to a neck extension of 20 degrees with the affected ear down. Throughout the process subject will be indicated to keep eyes open to allow the search of nystagmus. If torsional nystagmus or vertigo appears while the head is down it is indicative of posterior canal benign paroxysmal positional vertigo. | Baseline, immediately after intervention and 48 hours after intervention. | |
Secondary | Impact of dizziness in the quality of life in participants with Multiple Sclerosis. Dizziness Handicap Inventory (DHI). | Dizziness Handicap Inventory is a self-assessment questionnaire of 25- items and the total score is 100. The score is calculated by summing ordinal scales responses, higher scores means higher level of disability and handicap constituted by the physical, emotional and functional subscale. Physical and emotional subscales range from 0 to 36 points, and functional from 0 to 28. | Baseline, immediately after intervention and 48 hours after intervention. | |
Secondary | Independency in activities of daily living measure by Vestibular Disorders Activities of Daily Living Scale (VADL). | Vestibular Disorders Activities of Daily Living Scale (VADL) is a self-reported questionnaire that measures the independence on activities of daily living in people with vestibular disorders. This scale is composed by 28 items divided in three subcategories: 12 questions of functional skills, 9 questions of ambulation skills and 7 questions of instrumental skills. Each item is rate un a 10-point scale, in which higher score means less independence in ADL. The total score is the median of each subscale. | Baseline, immediately after intervention and 48 hours after intervention. |
