Inclusion Criteria:

  • Age 18~70
  • Spinal cord injury staging(AIS) A,B,C or D
  • Level of lesion is T10 and above
  • Distance between lesion and conus >60mm
  • Injured Time > 3 months
  • Capable of participating rehabilitation program
  • Agree to comply with all conditions of the study and to attend all required study training and visits

Exclusion Criteria:

  • With Obvious psychiatric disorder that cannot complete relevant questionaires
  • Cognitive impairment
  • Severe autonomic reflex disorder
  • Severe muscle atrophy and joint contracture
  • Cannot participate in spinal cord stimulation surgery or follow-up visits
  • Life expectancy less than 12 months
  • Abnormal blood or other physiological examinations that cannot conduct surgery, such as blood coagulation disorder or kidney/liver abnormalities
  • Uncontrollable hypertension, heart diseases, respiratory diseases or took related medicine in last 3 months
  • Unsuitable candidates in PI's perspective

Arms of the Study

Arm 1

Arm Type

Experimental

Arm Label

Stimulation

Arm Description

Participants will receive pre-implantation rehabilitation, implantation of the closed-loop spinal cord stimulator, and stimulation (according to the functional mapping) assisted rehabilitation post-implantation during the trial.

Outcomes

Primary Outcome Measures

WISCI III
A Common method used to evaluate SCI patient's walking capability in clinical setting
10-metre Walking Test 10-metre Walking Test 10-metre Walking Test 10 meter wlaking
10-Meter Walk Test (10MWT) is commonly used to measure walking speeds during two conditions: a self-selected normal speed, and a self-selected 'faster-than-normal' speed.
Weight Bearing Capacity
Weight-bearing capacity (WBC) is an important outcome to monitor and particularly relevant in patients with severe motor impairments who cannot walk independently. The investigators use LPG HUBER360 to examine subjects' weight bearing capacity

5. Study Description

Brief Summary
The purpose of this experiment is to evaluate the efficacy of Closed-loop Functional Spinal Cord Stimulation on Walking Rehabilitation in Patients after Spinal Cord Injury
Detailed Description
The whole course will last around 12 months, during which there will be: Pre-implant evaluations and standard rehabilitation (6-10 weeks), Stimulator implantation and stimulation optimization (4-8 weeks), Rehabilitation training with stimulation (6 months). At the end of the protocol, the study aims to make the patients walk better and faster.
