About this trial
The primary objective of the study is to examine whether there is a difference in disability after 12 months of Spinal Cord Stimulation (SCS) in patients with Persistent Spinal Pain Syndrome Type 2 (PSPS T2) after receiving a standardized pain medication tapering protocol before SCS implantation, a personalized pain medication tapering protocol before SCS implantation, or no tapering protocol before SCS implantation. The secondary objective of the study is to examine whether there is a difference after 12 months of SCS in PSPS T2 patients after receiving a standardized pain medication tapering protocol before SCS implantation, a personalized pain medication tapering protocol before SCS implantation, or no tapering protocol before SCS implantation on pain intensity, health-related quality of life, participation, domains affected by substance use, anxiety and depression, medication use, psychological constructs, sleep, central sensitization, and healthcare expenditure.
