With the close collaboration of the expert teams of Hainan University, Beijing Tiantan Hospital and Haikou People's Hospital, an innovative rehabilitation program combining epidural electrical stimulation with lower-limb exoskeleton has brought hope to an 11-year-old boy who was paralyzed due to a fall from a high altitude. After six months of systematic treatment, the child, who was once diagnosed with the most serious level of spinal cord injury (ASIA A), has now significantly improved his muscle strength and sensory function, successfully recovered to ASIA D, and will return to school in September this year.

On the one hand, this innovative rehab program activates the neural circuit by precisely implanting spinal cord electrodes, and uses the 32-channel programmable neural control chip independently developed by Hainan University, which breaks through the technical difficulties of the non-programmable imported equipment while restoring the natural movement timing of the human body. On the other hand, the core link of rehabilitation treatment is the coordinated application of EES and RoboCT's UGO220 rehab exoskeleton. Since December 2024, the boy M has been conducting 30-40 minutes of systematic training every day. "The equipment reminds me how to walk", M's feelings during the first training confirmed the activation effect of the program on neural remodeling.

The mechanical feedback provided by the rehab exoskeleton and the neural stimulation of EES form a "central-peripheral" closed loop, achieving a rehabilitation effect of 1+1>2, which is highly consistent with the latest research conclusions of the top international journal "Science Robotics". As the core equipment supplier of this solution, RoboCT's UGO220 exoskeleton achieves millisecond-level coordination with the EES system with its high-precision motion control capabilities. Its active training mode effectively stimulates the patient's residual muscle strength, and cooperates with the EMG adaptive filtering algorithm developed by the Hainan team to dynamically optimize the stimulation parameters and provide precise peripheral support for neural function reconstruction.

In fact, "spinal cord injury rehabilitation is a tough battle, and it requires the innovative power of combining both medicine and engineering." Associate Professor Liang Fengyan of Hainan University said that the team is currently working with a number of top institutions to continue to tackle key problems in the fields of stimulation chips, electrode materials and brain-computer interfaces. As the day for the boy to return to school is approaching, this solution that combines cutting-edge neural regulation and rehab exoskeleton is lighting up the hope for spinal cord injury patients.
