Background:
The success of neurofeedback training for vestibular rehabilitation depends largely on the type of feedback signal as well as on the specific parameters. Ideal training should be based on the individual balance deficits in patients in everyday situations. The present study is therefore aimed at investigating the therapeutic outcome of a new vibrotactile neurofeedback system for the first time in a pilot study.
Patients And Methods:
A total of 36 patients performed daily vibrotactile neurofeedback training (for 10 days) based on a sway analysis on the first day. The reduction of body sway and vertigo symptom scale (VSS) scores were calculated after the training and compared with those of the placebo group.
Results:
All five patient groups (characterized by different vestibular disorders) which performed the training with the correct feedback signal showed reduced body sway and VSS score (n=30). This effect was not visible in the placebo group.
Conclusions:
Individualized vibrotactile neurofeedback training as presented here with the Vertiguard® system appeared to improve balance during daily activities in all patient groups investigated, but not in controls. Future studies should investigate the efficacy of this new method in a larger sample as well as its long term effects.
