Masking Details
The day of the SCS implantation (RestoreSensor Surescan MRI Neurostimulator, Medtronic ©) the patients are randomized based on a random number assigned from www.randomization.com. The random number table is sent to the MedTronic representative in charge of the SCS mode control by the operating nurse who has no information about the study protocol. At this time, implantation practitioners and other research participants don't know which group is assigned first. Subjects with SCS implantation will be assigned 1:1 to either group C (conventional stimulation) or H (High-Density stimulation) to find an effective mode of pain relief.

Intervention Model
CROSSOVER
Model Details: V1 SCS trial for 6 days (3d conventional + 3d HD stimulation). V2 Enrolled if positive response (≥50% pain reduction) in one of the two modes during V1 + informed consent and randomization + blinding * Group C Conventional mode (2 weeks) + HD mode (2 weeks) * Groups H HD mode (2 weeks) + conventional mode (2 weeks) V3 After 2 weeks (+3d allowed) from V2. Cross-over performed by the MedTronics person in charge of adjusting the SCS mode. Mode-related information will not be shared with other researchers V4 (unblinding) 2 weeks from V3 (+3d allowed). Patients will be questioned about the more effective mode (primary endpoint). The SCS will be programmed accordingly V5 (follow-up 1) 4 weeks after V4 (±5d). Short-term assessment of effectiveness and safety V6 (follow-up 2) 12 weeks after V4 (±5d). Middle-term assessment of effectiveness and safety V7 (follow-up 3) 24 weeks after V4 (±5d). Long-term assessment of effectiveness and safety
