Assessment of spinal cord stimulation and radiofrequency: Chronic pain and psychological impact

Abstract

Pain has a major impact on anxiety and depression levels. The aim of this study is to demonstrate how these symptoms (depression and anxiety) could positively influence the perception of pain after neurostimulation system implantation.We enrolled 100 patients and divided in 2 different groups, by using tests screening such as Beck Depression Inventory (BDI), Hamilton Anxiety Rating Scale (HAM-A), Nursing Rating Scale (NRS): the group with spinal cord stimulation (SCS) and the group with pulsed spinal cord radiofrequency (RFP).We highlighted a significant decrease of scores (BDI, HAM-A, NRS) in each group between T0 (baseline) and T1. Moreover, the intra-group analysis showed a positive significant correlation between NRS and depressive and anxiety symptoms.We assert that the use of alternative methods (SCS and RFP) to the traditional pharmaceutical-surgical treatments, provide the reduction of the algic and anxiety-depressant symptoms, restoring also the perception of psychological well-being.
