Cervical Mobility and Vestibular Rehabilitation

Study Overview
=================
Brief Summary
-----------------
Vertigo, dizziness and imbalance are the main symptoms of vestibular dysfunction. They can lead to physical consequences, such as the reduction of postural control and falls, psychological and / or psychiatric consequences such as anxiety and depression, panic and cognitive changes, especially in the elderly. It is known that individuals affected by these disorders may improve with the completion of vestibular rehabilitation protocol.Treatment protocols can introduce variability of exercises to control the signs and symptoms related to vestibular diseases, in order to customize the treatment to affected individuals .

Detailed Description
-----------------
The objective of this study will be to compare the effectiveness of a multisensory exercises protocol of vestibular rehabilitation versus conventional protocol of Cawthorne & Cooksey exercises for the treatment of patients with vestibular disorders. Methods: There will be a Clinical Trial Random, blind, Hidden Allocation. The sample will consist of 54 subjects submitted to two different protocols of vestibular rehabilitation exercises (Intervention Group (IG) and Control Group (CG)), to be held with individual treatment once a week, totaling 12 attendences. All will be assessed before and after treatment and the main variables analyzed are general characteristics of the clinical signs and symptoms caused by vestibular diseases, perception of quality of life and functional capacity paras activities of daily life, body flexibility, range of motion in the region cervical, parameters of static and dynamic postural balance and the perception of the results promoted by the treatment of vestibular rehabilitation and will compare the results of the groups. Expected results: It is expected, clinically, that subjects who receive treatment through multisensory exercises Protocol for VR present reduction of clinical signs and symptoms of dizziness, complaints of pains and cervical joint limitations, parameters of improvement related to postural balance, aspects of functional capacity and quality of life.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Active Comparator: Intervention Group (IG)<br>Participants in the intervention group subjects (IG) will receive physiotherapy treatment in vestibular rehabilitation based on multisensory exercises consisting of the group of therapeutic proposals that stimulation of the vestibular, proprioceptive and visual associated with manual therapy treatment proposed by the techniques cervical global pompage and classic massage therapy on neck and shoulder girdle . | Other: Intervention Group (IG)<br>* Therapeutic approaches to this proposal are intended to promote muscle relaxation to increase range of motion and analgesia of neck and shoulder girdle region, as well as the fascial release these regions with the intervention of cervical global pompage, exercises for body mobility for upper limb and trunk in the positions supine, lateral and dorsal, sitting and standing and gradually followed by proprioceptive exercises to the lower limbs and trunk in sitting and standing positions with aid devices such as foams, pool baguettes, balance boards, Swiss balls, steps, trampolines and BOSU ( BOSU® Home Balance Trainer ). The exercises will be held in individual treatments lasting sixty minutes with a frequency of once a week for all group members.<br>* Other names: Multisensory Exercises Protocol of Vestibular Rehabilitation;|
| Experimental: Control Group (CG)<br>Participants in the control group subjects (CG) will receive physiotherapy treatment in vestibular rehabilitation based on Cawthorne and Cooksey Exercises, consisting of eye movements in different directions, slowly and quickly; head movements in different planes, with open and closed eyes, slow and fast; and body exercises such as lifting and sit, walk open and closed eyes, up and down ramps and stairs, as well as some activities and ball games. | Other: Control Group (CG)<br>* The exercises consist of eye movements in different directions, slow and fast; head movements in different planes, with open and closed eyes, slow and fast; and body exercises such as lifting and sit, walk open and closed eyes, up and down ramps and stairs, as well as some activities and ball games. The exercises will be held in individual treatments lasting sixty minutes with a frequency of once a week for all group members.<br>* Other names: Conventional Protocol of Cawthorne & Cooksey Exercises;|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Balance Measure from force platform (COP Measure) | To assess postural control by means of a force platform named BIOMEC400 (EMG System Brazil, SP Ltda), and the data sampled at 100 Hz variables will be used: pressure downtown area (A-COP in cm2), average velocity of COP (VEL in cm/sec), amplitude (AMP cm) and average frequency of COP (FM in Hz) in both movement directions: anterior-posterior (A/P ) and medial-lateral (M/L). | 12 weeks | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Timed Up and Go test (TUG) | Which evaluates the risk of falls. Starting from the sitting position, analyzes the transfer from sitting to standing, stability and progress of the ongoing changes without using compensatory strategies . | 12 weeks | 
| Functional Reach test (FRT) | Measure the mobility test with emphasis on the assessment of the balance. It is performed by asking the individual to stand up, next to a wall with shoulder flexion 90° and upper limbs in extension. Then he asks the individual to conduct an anterior flexion of the trunk, without the heels lose contact with the ground. Performance is measured by the distance traveled by the body's displacement (in centimeters), with the mean of three test attempts. | 12 weeks | 
| Agility Test | Agility test to evaluate the agility and dynamic balance. | 12 weeks | 
| Dizziness Handicap Inventory (DHI) | This questionnaire was developed and validated in order to evaluate the self- perception of the tax effects of dizziness on quality of life. | 12 weeks | 
| Vestibular Disorders Activities of Daily Living Scale Questionaire (VADL) | Evaluates the impact of dizziness and body imbalance in daily activities of vestibular individuals. | 12 weeks | 
| Visual Analog Scale (VAS) of Dizziness | Which indicates the intensity of vertigo symptoms, and varies on a numerical scale from zero to ten, where zero indicates the absence of dizziness and ten, the worst intensity of dizziness. | 12 weeks | 
| Fleximeter | Fleximeter to assess the range of motion of the cervical spine, consisting in a gravity - dependent inclinometer, whose range is a degree, attached to a velcro tape to be secured in head circumference participant. | 12 weeks |
