Identifying Biomarkers and Changes in Cerebrospinal Fluid Collected Pre and Post Spinal Cord Stimulation in Subjects Suffering From Chronic Refractory Pain Conditions

This is a single center exploratory study in subjects suffering from chronic refractory pain to identify cellular, molecular and protein biomarkers within cerebrospinal fluid (CSF). The study aims to identify any form of correlation between biological content of CSF and pain/treatment success. The study population include individuals suffering from chronic pain which has not been effectively treated with pharmacological treatment, medical intervention or alternative non-invasive treatments who have been scheduled for spinal cord stimulation.
