Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
This study compare vestibular rehabilitation with three different strategies (dynamic posturography exercises, optokinetic stimuli and exercises at home) and a control group, in people over 65 years. Balance tests are performed before vestibular rehabilitation and three weeks, six months and one year after it. Number of falls are quantified one year after vestibular rehabilitation.

RANDOMIZED
PARALLEL
PREVENTION
DOUBLE
After the first screening visit, the patients who grant their consent will be included in the study and randomised to one of the following study arms. Randomisation will be performed by C.H.U de Santiago Clinical Epidemiology and Biostatistics Unit. Once the informed consent form is signed, the care provider will contact the unit, which will give him the code of the arm to which the patient is assigned. A n= 20 block balanced randomisation sequence will be used. The investigator will analyse results and evolution, being blind type and duration of vestibular rehabilitation.
Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Vestibular rehabil.: CDP
Group A. The Smart Equitest program was used with a protocol of 10 exercises per session, which were customized depending on each patient´s deficit. The exercises involve visual biofeedback together with sensitive, real-time monitoring of movement. In some exercises, patients must maintain their center of gravity (COG) over the base of support, while in others the COG must be moved to a series of targets. In addition, the support surface and/or visual surround may also move in response to the patient´s own movement. The exercise difficulty was progressively increased throughout the rehabilitation sessions. The duration of each session was approximately 15 minutes. The distribution of sessions was one per day and five per week (2 weeks).
Vestibular rehabil.: CDP
Vestibular rehabilitation, ten sessions
Vestibular rehabil.: optokinetic stimuli
Group B. Patient has to stand in a dark room, wiht optokinetic stimuli around him/her. Ten sessions (one per day, five per week, two weeks), with progressive increase of stimulus speed (from 30º/sec the first day to 100º/sec the last), duration of session (from 5 minutes the first day to 15 minutes the last), stimulus complexity (horizontal stimuli in the first sessions, progressively adding vertical and rotating stimuli) and support surface difficulty (initially hard surface, last sessions on foam).
Vestibular rehabil.: optokinetic stimuli
Vestibular rehabilitation, ten sessions
Vestibular rehabil.: home exercises
Group C. The patient is given a list of exercises (and explained how to do them) to stabilise eye position and improve postural control. They are to be performed twice a day for two weeks. Approximate duration of each session: 15 minutes. The exercises must be supervised by a family member to verify adherence to the programme.
Vestibular rehabil.: home exercises
Exercises performed twice a day for two weeks. Approximate duration of each session: 15 minutes
Control group
Group D. No vestibular rehabilitation is developed.

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
* Having fallen at least once in the last 12 months.
* Using more than 15 seconds or needing support in the TUG test (normal limit calculated in previous studies).
* Obtaining a mean CDP SOT balance score of \< 68% (normal limit calculated in previous studies).
* Having fallen at least once in the CDP SOT.
Exclusion Criteria
* Organic conditions that prevent standing on two feet, necessary for assessment of balance and performance of vestibular rehabilitation exercises.
* Balance disorders caused by conditions other than age (neurologic, vestibular...).
* Reduced cultural level that prevents the patient from understanding the examinations and from granting informed consent.
