Clinical Trial Summary

The study aims to examine the plausible interventional mechanisms underlying the effects of epidural spinal cord stimulation.

Description:

The purpose of this study is for the treatment of spinal cord injury (SCI) paralysis patients use the signal by electrophysiological analysis of epidural spinal cord stimulation (SCS) settings that promote limbs activity so that SCI patients can restore motor ability under multiple sensory stimuli and multimodal electrical stimulation rehabilitation. The investigators hope to establish an atresia nerve regulation strategy and observe that the original blocked neural circuits can improve nerve plasticity by SCS. Even can establish new connections through residual nerves and allow SCI patients to rebuild neural circuits without SCS to restore limbs mobility and improve quality of life.
