Brain-Computer Interfaces for Tetraplegia Patients

Tetraplegic patients lose all four limbs' motor function due to cervical spinal cord injury and are the earliest and most central target population for invasive BCIs. This topic tracks clinical trials, decoding solutions, and daily-use cases for tetraplegia.

Eastern China's Shandong Performs Its First Invasive Brain-Computer Interface Implant

Surgeons in eastern China have implanted a brain-computer interface in a man who has been unable to move his limbs for more than two years. Eight ultraflexible electrodes sit 4 mm into his cortex, wired to a chip mounted on the skull. It is the first invasive BCI operation performed in Shandong province, and the patient now begins up to six months of training to control devices by thought.

VA optimizes implanted BCI to help paralyzed veterans use computers at home

The VA Office of Research and Development is advancing a high-performance implanted brain-computer interface (BCI) to improve independence for Veterans and others with tetraplegia or inability to speak due to ALS, spinal cord injury, or stroke. The project enhances deep learning decoders and multi-state gesture decoding, deployed on a battery-powered mobile BCI device for independent home use of computers and touch-enabled devices. Accuracy and usability will be evaluated in participants already enrolled in the BrainGate investigational clinical trial.

NeuroXess Says Two Paralyzed Patients Played Brain-Controlled Chess 800 km Apart

NeuroXess said two people with high-level paralysis played chess against each other across about 800 kilometers, between Shanghai and Nanchang in eastern China, using its "Triple-Full" (三全) brain-computer interface: one selected and placed pieces on a virtual board by thought, with the commands relayed in real time to a robot stand-in that moved the pieces at the other end, where the second participant gripped physical pieces through a brain-controlled exoskeleton glove. The company said the first participant was implanted at Huashan Hospital, Fudan University, in October 2025, moved a cursor by thought on the fifth day after surgery and reached 5.2 bits per second after 17 days of training, while the second was implanted at the First Affiliated Hospital of Nanchang University in December 2025 and was eating, drinking and writing with a brain-controlled exoskeleton one month after surgery. The outcomes come from the vendor's own account and have not been validated in peer-reviewed publication.
