(as of April 2025)
1. Technological Breakthroughs and Core Directions
Neurotechnology and brain-computer interfaces (NeurotechBCI) have established three key pathways in medical rehabilitation:
- Invasive BCI: Led by Neuralink and Tsinghua University’s NEO, addressing challenges in minimally invasive implantation and long-term biocompatibility.
- Non-invasive BCI: Pioneered by Meta’s neural decoding and BrainCo’s bionic limbs, focusing on high-precision signal acquisition and multimodal feedback.
- Hybrid Closed-Loop Systems: Integrating EEG, fMRI, and functional electrical stimulation (FES), such as MIT’s brain-spinal cord stimulation interface.
2. Progress in Key Disease Areas
Stroke and Motor Function Recovery
- Motor Imagery Breakthrough: Shanghai Advanced Research Institute’s MI-BCI algorithm improved hand function recovery in stroke patients by 40%.
- Exoskeleton-BCI Integration: Japan’s Cyberdyne HAL system enables paralyzed patients to walk autonomously via cortical intent detection.
- Closed-Loop Neuroregulation: ZhenTian’s BCI-VR-robotics system enhances upper limb mobility by 35% through neural plasticity induction.
Spinal Cord Injury (SCI) Rehabilitation
- Wireless Implant Revolution: Tsinghua’s NEO device achieved the first at-home BCI trial, allowing patients to perform tasks like drinking via brainwave-controlled gloves (accuracy >90%).
- Brain-Spinal Interfaces: EPFL’s closed-loop system restored standing ability in chronic paraplegics by converting motor cortex signals into epidural stimulation.
- Speech Restoration: Harvard’s brain-controlled speech synthesizer enables basic communication at 15 words/minute for aphasia patients.
Neurodegenerative Disease Intervention
- Parkinson’s Therapy: NeuroOne’s Evo sEEG electrodes reduce tremors by 68% through basal ganglia monitoring and stimulation (FDA-approved).
- Alzheimer’s Early Intervention: Fudan University’s non-invasive BCI slows cognitive decline by modulating default mode network activity.
Mental Health Treatment
- Depression Therapy: JingYu Medical’s dual-target deep brain stimulation achieved 55% remission in treatment-resistant depression (FDA Breakthrough Designation).
- Addiction Control: NeuroSee’s neurofeedback system reduced heroin relapse rates to 22% within six months.

Conclusion: From Functional Replacement to Neural Remodeling
NeurotechBCI has transitioned from replacing lost functions to enabling neural plasticity. By 2030, advancements in flexible electronics, optogenetics, and quantum computing aim to:
- Restore independent living for >50% of chronic paralysis patients.
- Reduce post-stroke motor recovery to <3 months.
- Achieve 95% accuracy in early neurodegenerative disease diagnosis.
To ensure equitable benefits, global governance must evolve through interdisciplinary ethics committees, diffusion control frameworks, and affordable licensing models.
