Emotional Outcomes in Chronic Pain Patients Following Spinal Cord Stimulation: A Systematic Review

INTRODUCTION

•Chronic pain affects health-related quality of life by imposing physical and psychological limitations.

•Recent studies support Spinal Cord Stimulation (SCS) efficacy in reducing pain, improving physical functioning and decreasing opioid consumption1,2.

•Our objective is to assess SCS impact on emotional functioning in patients with chronic pain syndromes.

METHODS

The PRISMA guidelines were followed.

Inclusion criteria: Original research reporting emotional outcomes following SCS implantation for chronic pain.

Emotional functions were assessed by validated questionnaires: emotional component of Short-Form-36 (SF-36 MHS), SF-12 MHS, Pain Catastrophizing scale (PCS), Beck Depression Inventory (BDI), Hospital Anxiety and Depression Scale (HADS).

RESULTS

A total of 1277 studies were screened. Eighty-three articles were included in the qualitative analysis.

The most frequently reported measures were PCS (n=28), BDI (n=27), SF-36 MHS(n=25), and SF-12 (n=7).

SF-36 MHS/SF-12 reached statistically significant improvement in 16 out of 32 studies. Ten studies showed a positive trend, and five reported no significant change following the SCS implantation

Conclusions

This review highlights the importance of multifactorial patient assessment when evaluating SCS efficacy.

SCS therapy can provide improvements in patient’s mental health-related quality of life measured by SF-36 MHS and SF-12 MHS.

The observed increase coincides with reduction in anxiety and pain catastrophizing.
