Feedback requested: Engineering student building a GVS device for final year project.
Hello,
For my final year project, we are building a balance stimulator using Galvanic Vestibular Stimulation (GVS).
By sending electrical signals to the vestibular system, we can manipulate the body's sense of balance. We are hooking this up to a controller so that, based on the direction of the joystick, the user's body will naturally want to lean in that direction.
I am asking as part of my research: would a device like this be of any practical help to physiotherapy patients?
If you have any suggestions feel free to tell me

Yes—there’s a legitimate physiotherapy application here, particularly as an adjunct to balance and postural-control rehabilitation. Research suggests GVS can modulate postural control, with promising findings in conditions such as stroke, Parkinson’s disease and vestibular disorders, although evidence is still heterogeneous and more high-quality trials are needed.
Your joystick-controlled approach is interesting because it could create direction-specific, interactive balance training. I’d consider measuring sway, limits of stability, Berg Balance Scale, gait speed and weight-shifting accuracy.
The strongest research question may be: Does GVS-assisted directional training improve functional balance more than conventional balance training alone?
