Primary Outcome Measures
NameTimeMethod
The reduction rate of VAS value between before and after tSCS treatment. If a decrease in VAS value more than 50% is observed, it has a therapeutic effect (EF), and if a decrease in VAS value less than 50% is observed, the treatment effect is poor (NE) . The optimal timing of treatment is determined by divided into two groups; Early Treatment group (ET) , Late Treatment group (LT), depending on the time of start of treatment. We examine the time when the Odd ratio between the EF group and the NE group is maximum.
Secondary Outcome Measures
NameTimeMethod
We examine the efficiency of the VAS value less than 20mm, HADS and PCS before and after tSCS treatment. We plan to examine changes in EQ-5D levels, analyze factors related to patient information and treatment effect, including spinal MRI findings, and analyze the number of complications associated with tSCS treatment.
