Restoration of vestibular function: basic aspects and practical advances for rehabilitation

Area of Science:

• Neuroscience
• Vestibular System Function
• Human Locomotion

Background:

• The vestibular system is crucial for balance, locomotion, and spatial orientation.
• Lesions in the vestibular system lead to significant functional disruptions.

Purpose of the Study:

• To review three decades of research on vestibular compensation mechanisms.
• To present updated theories on vestibular compensation and rehabilitation principles for patients with vestibular loss.

Main Methods:

• Synthesis of the author's research on animal models and patients with vestibular defects.
• Analysis of basic mechanisms underlying vestibular compensation theories.
• Review of management and rehabilitation strategies for vestibular disorders.

Main Results:

• Static vestibular deficits are fully compensated via plastic changes in vestibular nuclei.
• Dynamic vestibular deficits show poor compensation, relying on substitution and vicarious strategies.
• Effective rehabilitation involves early intervention, active retraining, individualized programs, standardized testing, and judicious use of medications like betahistine dihydrochloride.

Conclusions:

• Optimal recovery of vestibular function is achieved through a combination of early, active rehabilitation and appropriate pharmacological support.
