Summary

Real-time feedback can improve balance exercises for vestibular deficits. Continuous visual feedback enhanced performance but may cause dizziness, suggesting multimodal or vibrotactile feedback for home devices.

Background:

Vestibular rehabilitation therapy (VRT) improves balance and gait in individuals with vestibular deficits.
Patient adherence to home-based VRT exercises is often inconsistent.
Real-time feedback may enhance exercise adherence, execution, and overall rehabilitation outcomes.

Purpose of the Study:

To compare the effects of visual and vibrotactile feedback on postural performance.
To inform the selection of an optimal feedback modality for home-based balance rehabilitation devices.

Main Methods:

Eight subjects with peripheral vestibular deficits and eight age-matched controls participated.
Subjects performed eyes-open tandem Romberg stance trials with various feedback modalities (vibrotactile, discrete visual, continuous visual, multimodal) and baseline (no feedback).

Outcome measures included body tilt (M/L and A/P), time within a no-feedback zone, and a user ranking survey.

Main Results:

All feedback modalities improved postural performance compared to baseline for both groups.
No significant performance differences were found between vibrotactile, discrete visual, or multimodal feedback.
Subjects with vestibular deficits showed best performance and highest ranking with continuous visual feedback; however, controls ranked it lowest.

Conclusions:

Continuous visual feedback improved postural control in individuals with vestibular deficits but may induce dizziness.
Vibrotactile, discrete visual, and multimodal feedback offer viable alternatives without significant performance trade-offs.
Further research should consider feedback modality limitations for diverse VRT exercises and patient conditions.
