  "account": "On 24 October 2023, teams led by Zhao Guoguang (Xuanwu Hospital) and Hong Bo (Tsinghua University) implanted the NEO wireless epidural brain-computer interface (BCI). The patient was a 54-year-old man with complete C4 spinal cord injury (ASIA A) from a car accident, quadriplegic for 14 years. Discharged ten days later, he trained three months at home. At a 29 January 2024 trial-phase summary meeting the team reported he could drive a pneumatic glove with his brain activity to drink water unaided. Grasp-decoding accuracy was above 90%, with improved ASIA scores and somatosensory evoked potentials. A September 2024 preprint reported nine months of home use: a 0.91 grasp-detection F1-score, eating and drinking, and a 27-point ARAT gain.",

Calibrated in about ten minutes on beta, low-gamma and high-gamma features of eight-channel epidural ECoG, it detects grasp intention and triggers the pneumatic glove. The preprint reports 94% calibration accuracy and a grasp-detection F1-score rising above 0.9 after three months (average 0.91 over nine months). It gives 100% object-transfer success with the BCI against 35% without. The electrodes, implant, surgery and glove are not AI. The authors attribute the later neurological recovery to repeated BCI training, not the decoder alone."

At a 29 January 2024 trial-phase summary meeting the team reported he could drive a pneumatic glove with his brain activity to drink water unaided. Grasp-decoding accuracy was above 90%, with improved ASIA scores and somatosensory evoked potentials. A September 2024 preprint reported nine months of home use: a 0.91 grasp-detection F1-score, eating and drinking, and a 27-point ARAT gain.",

The patient was a 54-year-old man with complete C4 spinal cord injury (ASIA A) from a car accident, quadriplegic for 14 years. Discharged ten days later, he trained three months at home. At a 29 January 2024 trial-phase summary meeting the team reported he could drive a pneumatic glove with his brain activity to drink water unaided. Grasp-decoding accuracy was above 90%, with improved ASIA scores and somatosensory evoked potentials. A September 2024 preprint reported nine months of home use: a 0.91 grasp-detection F1-score, eating and drinking, and a 27-point ARAT gain."
