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

Participants will have a 16-electrode epidural array implanted in the C4-C7 and T11-L2 areas of the spinal cord. Following a 2 weeks recovery period, patients will engage in a structured training of physical rehabilitation and electrical stimulation.

American Spinal Injury Association (ASIA-2019) Impairment Scale
To measure and record disease history In simpler terms, it's a 5-point scale that categorizes individuals from "A" (complete spinal cord injury) to "E" (normal sensory and motor function), with each letter representing a different level of injury severity: A: Complete spinal cord injury. B: Sensory incomplete injury. C: Motor incomplete injury. D: Motor incomplete injury. E: Normal sensory and motor function.
Time frame: To measure assessing change between pre-implant and every 3 months until 24 months.

Modified Ashworth scale
To measure the increase of muscle tone,it uses a 6-point system. Scores range from 0 to 4. Lower scores indicate normal muscle tone, while higher scores indicate spasticity or increased resistance to passive movement.
Time frame: To measure assessing change between pre-implant and every 3 months until 24 months.
Barthel Index
To measure performance in activities of daily living
Time frame: To measure assessing change between pre-implant and every 3 months until 24 months.

A brief version scale of World Health Organization Quality-of-Life scale
Time frame: To measure assessing change between pre-implant and every 3 months until 24 months.
Spinal Cord Independence Measure

Action Research Arm Test Scoring Sheet
To measures upper limb function by scoring the ability to complete functional tasks.
Time frame: To measure assessing change between pre-implant and every 3 months until 24 months.
Berg Balance Scale
To measure balance and the risk of falls,it's a list of 14 things to rate, where each thing has a scale from 0 to 4. Zero means the lowest function, while four means the highest function.
