# NBI — Neural Balance Innovations > Neural Balance Innovations develops Galvanic Vestibular Stimulation (GVS) devices to reduce motion sickness, cybersickness, and advance vestibular research. Made in France. --- ## Home — NBI Galvanic Vestibular Stimulation Device Unlock Sensory Potential. Powered by GVS. NBI is a research laboratory specializing in vestibular stimulation for breakthrough applications. Our technology relies on a clinically validated, calibrated electrical stimulation applied to the vestibular nerve. This precise signal reduces the sensory conflict in VR, eliminating cybersickness for a smooth, comfortable immersion -- no nausea, no disorientation. ### How GVS Works **What is Cybersickness?** Cybersickness is the discomfort -- nausea, dizziness, eye strain, disorientation -- experienced when using VR headsets or simulators. It results from a sensory conflict: your eyes perceive motion, but your inner ear senses that you're stationary. This mismatch confuses the brain and triggers symptoms similar to motion sickness. Between 25% and 60% of VR users are affected. **The Vestibular System** The vestibular organ is located in the inner ear. It consists of the semicircular canals (detecting rotational movement) and the utricle and saccule (detecting linear acceleration and gravity). Together, these structures are essential for maintaining balance, posture, and spatial orientation. Your inner ear is the body's motion sensor. **How GVS Bridges the Gap** Galvanic Vestibular Stimulation applies a gentle, calibrated electrical current to the vestibular nerve via electrodes behind the ears. This modulates the balance signals sent to the brain, reducing the conflict between visual and vestibular inputs. The result: a more comfortable, immersive VR experience without nausea or disorientation. GVS aligns what you see with what you feel. ### Clinical Studies Our clinical studies validate the safety and efficacy of our vestibular stimulation technology in real-world conditions. - Federal University of Ceará (Brazil, Q3 2025): Within-subject crossover study with 20 volunteers -- VR immersions (sham vs GVS), assessed via SSQ, tolerance and acceptability. - Federal University of Ceará (Brazil, Q3 2026): Second phase of clinical study in collaboration with the Federal University of Ceará. - ESIEA (Laval, France, Q4 2026): Clinical study in partnership with ESIEA in Laval. - ESIEA (Laval, France, Q1 2027): Second clinical study in partnership with ESIEA in Laval. --- ## Stimbox® GVS — Product The Stimbox® uses clinically validated calibrated electrical stimulation for gentle, non-intrusive vestibular nerve stimulation.
