Clinical Trial to Evaluate the Safety and Efficacy of an Implantable Neural Acquisitor & Stimulator System in Patients With Motor Disability

To evaluate the safety and efficacy of an implantable neural acquisitor & stimulator system in patients with motor disability（Complete or incomplete quadriplegia due to spinal cord injury, brain stem stroke, amyotrophic lateral sclerosis and other motor neuron disorders).

Through brain-computer interface alternative technology, patients can control the external equipment（wheelchairs, robotic arms, the WeChat app and other physical aids）with brain signals to improve the patients quality of life.

Inclusion criteria

• Aged between 18 and 80 years of age;
• Complete or incomplete quadriplegia due to spinal cord injury, brain stem stroke, amyotrophic lateral sclerosis and other motor neuron disorders;
• After the neurological assessment, the brain motor-related cortex is functional, and there is no obvious organic disease or functional disease；
• The above diseases have been diagnosed for at least 12 months and stable for at least 6 months after standard treatment；
• The patient had normal cognitive function, good compliance and volunteered to participate in the clinical trial.

Exclusion criteria

• Visual impairment such that extended viewing of a computer monitor would be difficult even with ordinary corrective lenses；
• Combined with progressive neurological disease；
• Combined with surgical contraindications identified by surgeons and anesthesiologists;
• Participating in other clinical trials;
• Other conditions deemed inappropriate by investigators and medical staff.
