Effects of Active Versus Passive Recharge Burst Spinal Cord Stimulation on Pain Experience in Persistent Spinal Pain Syndrome Type 2: a Multicenter Randomized Trial (BURST-RAP Study)

This study compares two different settings of a spinal cord stimulator for people who still have back and leg pain after spine surgery. The device delivers small electrical bursts to the spinal cord to reduce pain. The trial compares an "active recharge" mode versus a "passive recharge" mode to see which works better for patients who tend to catastrophize their pain experience. You may be eligible if... - You are between 18 and 70 years old - You have Persistent Spinal Pain Syndrome Type 2 (ongoing pain after back surgery) lasting at least 6 months - Your back and/or leg pain scores 5 or higher on a 0–10 scale - You score at least 20 on the Pain Catastrophizing Scale - A multidisciplinary team including a psychologist has approved you for a spinal cord stimulator implant - You have no significant motor (movement) deficits on neurological exam You may NOT be eligible if... - You are pregnant, nursing, or plan to become pregnant - Your pain has been rapidly escalating or changing in the last month - Your BMI is 35 or higher - You had injection therapy or radiofrequency treatment for your back/leg pain in the last 3 months - You already have an implanted cardiac device (pacemaker, ICD) or a previous spinal cord stimulator or pain pump - You had previous neurostimulation therapy - You are unable to operate the device Talk to your doctor to see if this trial is right for you.
