Galvanic vestibular stimulation (GVS) shows potential for balance rehabilitation by stimulating neural pathways. This review identifies clinical applications for GVS in various neurological and vestibular disorders.
Area of Science:
- Neuroscience
- Rehabilitation Medicine
- Clinical Neurology
Background:
- Vestibular rehabilitation aims to improve balance and reduce dizziness.
- Galvanic vestibular stimulation (GVS) is a non-invasive neuromodulation technique.
- Evidence for GVS in clinical practice requires systematic evaluation.
Approach:
- Systematic review of scientific literature.
- Searched PubMed, Web of Science, MEDLINE, Scopus, LILACS, and SciELO.
- Included studies on clinical applications of GVS, excluding reviews and case reports.
Key Points:
- Identified clinical applications of GVS for Ménière's disease, vestibular neuritis, and Parkinson's disease.
- GVS applications extend to central nervous system lesions, spinal cord diseases, and cognitive functions.
- The review compiled evidence from 23 selected articles.
Conclusions:
- Galvanic vestibular stimulation is a promising strategy for balance rehabilitation.
- GVS stimulates central connections crucial for postural balance.
- It facilitates neuroplasticity, aiding recovery from postural imbalance.
