Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Vestibular Rehabilitation by the standard protocol of Cawthorne and Cooksey or by the Protocol of Cawthorne and Cooksey modified (multicomponents). The standard protocol of Cawthorne and Cooksey consists of eye, cephalic and trunk exercises, in order to stabilize the gaze, reduce dizziness and improve the postural control. This protocol was based on articles: Cawthorne T. The physiological basis for head exercises. J Chart Soc Physiother. 1944;29:106-7 and Cooksey FS. Rehabilitation in vestibular injuries. Proc Roy Soc Med. 1946; 39:273–278. The Cawthorne and Cooksey modified protocol contains the same exercises of the standard protocol with others components (flexibility, cognitive, sensory interaction and strength). Vestibular Rehabilitation protocols will be held at the Neurotology clinic, taught by trained physical therapist in individual sessions twice a week with 50 minutes, for two months (total 16 sessions)

Eligibility
Key inclusion criteria
The inclusion criteria are: age and over 65 years, both genders and clinical diagnosis of chronic dizziness due to vestibular disorders. This clinical diagnosis is given when there is failure in the compensation of dizziness for 2 months or more after the triggering event.
Minimum age
65 Years
Maximum age
99 Years
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
Will be excluded elderly patients with dizziness of no vestibular origin, cognitive deficit (reference values for the education of the Mini-Mental State Examination), locomotion with a walker and wheelchair, practicing regular physical activity, which performed rehabilitation of balance disorders in the past six months and use of drugs with action on the vestibular system. Elderly with Positional Benign Paroxysmal Vertigo (BPPV) are also excluded, since the intervention protocol does not address the repositioning maneuvers.

Summary
Brief summary
This study aims to analyze and compare the effectiveness of two protocols Vestibular Rehabilitation (Cawthorne & Cooksey standard and modified Cawthorne & Cooksey) on functional capacity and body balance in elderly patients with chronic dizziness of vestibular origin.
The protocol of Cawthorne & Cooksey exercises is absent of sensorial manipulation (proprioceptive and visual), modification of the support base and other components sensorimotor. Given the fact that the good performance in daily acitivities and postural control in the elderly is dependent on the connection between all systems, not only by the vestibular system, it is believed that the exercises involving multiple components to be scaled up to the protocol of Cawthorne & Cooksey possibly resulting in gain greater independence in daily activities, the control body and consequently in reducing falls.
