The PROSTIM study is an ongoing prospective, multicentric and observational clinical study. Patients are recruited in three different centers in Eastern Belgium from May 2018 onwards. This real-world data collection approaches the outcome assessment of daily medical practice. A hierarchical cluster analysis is used to identify significant patient clusters based on the Visual Analogue Scale (VAS), Oswestry disability index (ODI), Pain Vigilance and Awareness Questionnaire (PVAQ), Pain Catastrophizing Scale (PCS) and EuroQol with five dimensions for health-related quality of life (EQ-5D). Patient clusters will be assessed on the change in biopsychosocial variables after six weeks, three and twelve months. Secondary outcomes include the comparison of pain medication use, SCS parameters, treatment satisfaction and return to work.

Eligible patients will undergo a SCS trial period for three weeks (as legally defined by the reimbursement authorities). The leads can be placed both surgically of percutaneously with an external trial stimulator. Surgical implantation of an implanted pulse generator (IPG) is performed if the patient achieves at least 50% pain reduction and a reduced pain medication use (reimbursement requirements) during the trial period. Subsequently, the implanted devices are programmed to the optimal parameters in collaboration with a nurse specialized in SCS treatment. The patients are educated on the use of the patient programmer.
