Chronic Pain Clinical Trial
Official title:
Effects of Paresthesia Free Spinal Cord Stimulation on Pain Intensity, Functional Improvement, Pain Thresholds and Sensory Perceptions in Chronic Pain Patients
The goal is to document efficacy of PF-SCS therapy in a blinded fashion and better understand how SCS therapy works in the clinical setting. Overall the investigators hope to improve patient care and selection of candidates who have the best potential for effective pain relief from an expensive and invasive therapy.

Primary | 20% increase of NRS (numerical rating scale) pain scale | 20% increase on low back pain NRS pain scale (0 = no pain and 10= maximum pain imaginable) while on LAP (lowest amplitude program) compared to OPP (optimal program). | from date of consent until end of study (14-28 days) | |
Secondary | Quantitative Sensory Testing (QST) Results | Compare sensory perception on both the area of pain and the non-painful area on the opposite side while on the OPP (optimal program) and the LAP (lowest amplitude program). The following tests will be analyzed:
warm sensation (degrees Celsius) heat pain threshold (degrees Celsius) heat pain tolerance (degrees Celsius) wind-up (NRS pain scale) |
from date of consent until end of study (14-28 days) | |
Secondary | Daily diary results | Subject reported responses regarding their pain while using the OPP (optimal program):
global impression of change in pain (0=no pain, 10=worst pain) impact on sleep and mood (0= does not interfere, 10= interferes completely) daily living (0= does not interfere, 10= interferes completely) enjoyment and general activity (0= does not interfere, 10= interferes completely) |
from date of consent until end of study (14-28 days) |
