Spinal cord stimulation (SCS) has shown to be an effective treatment for patients with persistent spinal pain syndrome Type 2 (PSPS Type 2). The method used to deliver electrical charge in SCS is important. One such method is burst stimulation. Two variations of burst waveforms are currently in use: one that employs active recharge and one that uses passive recharge. It is still unknown if there are clinical differences between active recharge and passive recharge burst SCS. To date, no clinical studies have been performed that directly compared these two burst stimulation waveforms. The objective of this Randomized Clinical Trial (RCT) is to assess and compare effect of passive recharge burst SCS with active recharge burst SCS on pain relief and motivational-emotional facets of pain
