Neurotech BCI: Restoring Mobility and Treating Neurological Disorders Through Brain-Computer Interfaces
Neurotech BCI: Restoring Mobility and Treating Neurological Disorders Through Brain-Computer Interfaces
Key Application Areas
1. Motor Function Restoration for Paralysis Patients
Spinal Cord Injury (SCI) Treatment:
- Utilizes invasive/non-invasive BCI to decode brain signals for exoskeleton or wheelchair control
- Case Study: Dutch paraplegic regained walking/stair-climbing ability via wireless brain-spine interface (BSI)
- Mechanism: WIMAGINE system converts neural signals to spinal cord stimulation in real-time
- Efficacy: RCTs show significant Fugl-Meyer score improvements with FES integration
Post-Stroke Rehabilitation:
- EEG-BCI captures impaired cortex signals combined with robotic training
- Clinical Evidence: BCI+VR training improves fine motor recovery efficiency
- Innovation: Action Observation BCI (AO-BCI) reduces traditional rehab duration
2. Neurological Disorder Interventions:
- Parkinson’s Disease: Modulates basal ganglia activity to reduce tremors
- Chronic Pain: Closed-loop neurofeedback provides substantial pain relief
- ALS: Enables text communication for locked-in patients via intracranial EEG-BCI
