Study on Feasibility of Stimulation on the Lumbar Part of the Spinal Cord to Improve Mobility Recovery in Patients With Sub-acute Spinal Cord Injury

The STIMO-2 study aims to investigate TESS-supported rehabilitation training in sub-acute spinal cord injury (\< 6 months post-injury). The primary endpoint of this study is to assess the safety and feasibility of TESS. The preliminary effectiveness of the therapy is the secondary study endpoint. The mobility recovery status of patients, who undergo TESS-supported rehabilitation, will be assessed at 12 months post SCI, compared to their predicted recovery expectations based on standard rehabilitation program
