Eligibility

Sex/Gender
All

Inclusion criteria

Inclusion criteria: -Patients with intractable neuropathic pain resistance to medication treatments using more than two drugs -18 years of age or older -Pain scale of VAS (Visual analog scale) is more than 4 point -Patients who have obtained written consent from the patient

Exclusion criteria

Exclusion criteria: -Patients receiving anti-cancer therapy -Patients with a history of drug abuse -Patients with histories of spine or spinal cord surgery at the site through which the spinal cord stimulation electrode passes or will be placed -Patients for whom local and general anesthesia cannot be performed -Patients with high risk of surgery, such as patients with unstable angina pectoris and with end-stage liver disease presenting with hepatic encephalopathy -Patients with diabetes mellitus who are not well controlled (HbA1c 9% or more) -Patients with serious complications (liver disease, kidney disease, heart disease, lung disease, blood disease, brain disease, etc.) -Pregnant or potentially pregnant patients -Patients who are considered as inappropriate by a head of research or research assignations

Design outcomes

Primary

MeasureTime frame
Effective is defined as achieving more than 33% for pain improvement by VAS. Verify the new stimulus method (DTM or FAST stimulation) has higher rates of pain improvement than conventional stimulation at the end of the SCS trial.

Secondary

MeasureTime frame
1 Evaluate improvement rates of pain scale VAS for each stimulation methods by each causative disease at the SCS trial. 2 Comparison of improvement rates of DTM and FAST stimulation of pain scale VAS by all cases and causative diseases. 3 Assessments of changes of pain scales and psychiatric scores compared to preoperative and postoperative at 1, 3, 6, 12, 18 months, and final follow-up (24 months) from spinal cord stimulation implantation. 4 Long-term effect is defined as the effect (improvement of more than 33% by VAS before preoperative) is continued at postoperative 1, 3, 6, and 12 months. Assessments of the correlation with the long-term effect and related background factors. 5 Extraction of diseases related to this study 3 months after surgery.
