Clinical Trial 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

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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	WISCI III	A Common method used to evaluate SCI patient's walking capability in clinical setting	Change from Baseline to the 8 month after implantation.
Primary	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.	Change from Baseline to the 8 month after implantation.
Primary	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	Change from Baseline to the 8 month after implantation.
