Brain-controlled Spinal Cord Stimulation in Participants With Chronic Stroke for Lower and Upper Limb Rehabilitation

The purpose of this clinical study is to evaluate the preliminary safety and effectiveness of using a cortical recording device (ECoG) combined with cervical and lumbar targeted epidural electrical stimulation (EES) of the spinal cord to restore voluntary motor functions of upper and lower limbs in participants with chronic stroke suffering from mobility impairment. The goal is to establish a direct bridge between the motor intention of the participant and the spinal cord, which should not only improve or restore voluntary control of arm and leg movement and support immediate mobility, but also promote neurological recovery when combined with neurorehabilitation.
