Introduction Some patients with severe impairment of body balance do not
obtain adequate improvement from vestibular rehabilitation (VR). Objective To
evaluate the effectiveness of Vertiguard™ biofeedback equipment as a sensory
substitution (SS) of the vestibular system in patients who did not obtain
sufficient improvement from VR. Methods This was a randomized prospective
clinical study. Thirteen patients without satisfactory response to
conventional VR were randomized into a study group (SG), which received the
vibrotactile stimulus from Vertiguard™ for ten days, and a control group (CG),
which used equipment without the stimulus. For pre- and post-treatment
assessment, the Sensory Organization Test (SOT) protocol of the Computerized
Dynamic Posturography (CDP) and two scales of balance self-perception,
Activities-specific Balance Confidence (ABC) and Dizziness Handicap Inventory
(DHI), were used. Results After treatment, only the SG showed statistically
significant improvement in C5 (p = 0.007) and C6 (p = 0.01). On the ABC scale,
there was a significant difference in the SG (p = 0.04). The DHI showed a
significant difference in CG and SG with regard to the physical aspect, and
only in the SG for the functional aspect (p = 0.04). Conclusion The present
findings show that sensory substitution using the vibrotactile stimulus of the
Vertiguard™ system helped with the integration of neural networks involved in
maintaining posture, improving the strategies used in the recovery of body
balance.

Introdução Alguns pacientes com déficit severo do equilíbrio corporal
submetidos à reabilitação vestibular (RV) podem não apresentar resultados
satisfatórios. Objetivo Verificar a eficácia do equipamento de biofeedback
Vertiguard™ como substituto sensorial do sistema vestibular em pacientes sem
bons resultados à RV. Método Estudo prospectivo clínico randomizado. Treze
pacientes sem resposta satisfatória à RV convencional foram randomizados entre
grupo de estudo (GE), que utilizou o estímulo vibratório do Vertiguard™ por
dez dias e grupo controle (GC) que usou o equipamento desligado. Para
avaliação pré e pós-tratamento foi utilizado o protocolo Teste de Integração
Sensorial (TIS) da Posturografia Dinâmica Computadorizada (PDC) e duas escalas
de autopercepção do equilíbrio: ABC (Activities-specific Balance Confidence) e
DHI (Dizziness Handicap Inventory). Resultados Apenas o GE apresentou melhora
estatisticamente significante em C5 (p = 0,007) e C6 (p = 0,01) da PDC após
treinamento. Na escala ABC houve diferença significante no GE (p = 0,04). No
DHI ocorreu diferença significante no aspecto físico em ambos os grupos e no
aspecto funcional (p = 0,04) apenas no GE. Conclusão O estímulo de
substituição sensorial do Vertiguard™ auxiliou a integração das redes neurais
e na manutenção da postura, melhorando as estratégias utilizadas na
recuperação do equilíbrio corporal.
