Vestibular rehabilitation

Vestibular rehabilitation uses the plasticity of the central nervous system, i.e. its ability to develop new balancing strategies in light of an impairment in the peripheral vestibular system. Sometimes there is no peripheral vestibular deficit but a deterioration in the central use of inputs from the inner ear.

Two types of mechanism are involved: habituation, which reduces the intensity of the response by repeating the stimulation, and adaptation, which leads to a reorganization of the neural circuits, a recalibration in vestibulo-ocular and vestibulo-spinal reflexes, and better use of visual and proprioceptive resources.

To do this, vestibular rehabilitation uses various methods of sensory habituation, substitution or illusion through a combination of physical exercises and/or instrumental manoeuvres using a rotational chair, oculo-motor ramps, optokinetic target generators, posture platforms, etc. According to the literature, the mean duration for a VR programme is 4 to 10 weeks.

Different environments are possible

Rotational chair

The patient is placed on a chair rotating at high speed to the right or left and stopped abruptly. The patient is then asked to fix their gaze on a target in front of them and to say when the target stops moving. These accelerated rotations make the vestibular inputs symmetrical.

Optokinetic stimulation

Spots of light are shone in front of the patient, who is standing and must maintain balance either on a hard surface or on a foam mat. These procedures are designed to encourage the use of vestibular inputs and adjust the patient’s faith in them and the resulting stabilisation strategies based on the use of visual information.

Proprioceptive stimulation

The patient is placed on a foam mat and must learn to maintain balance on a framiral, EquiTest or Satel moving platform. The aim is to maintain balance during the sessions.


Vestibular rehabilitation aims to generate central compensation for a unilateral or bilateral, complete or partial vestibular deficiency, compensation that, for one reason or another (age, psychological context, etc.) the patient is not able to produce spontaneously, and therefore resorts to avoidance strategies that artificially worsen the symptoms. However for vestibular rehabilitation to be effective, it is essential for the deficiency to be stable and not progressive, which, as we shall see, is important for the indications.
In elderly patients suffering from unsteadiness, vestibular rehabilitation significantly reduces complaints and prevents falls, which are the second cause of death after stroke.
