Aim: Spinal cord stimulation (SCS), one neuromodulation technique, has come to represent the basis of pain management in numerous chronic painful conditions, such as refractory radiculopathy, chronic regional pain syndrome, postoperative chronic pain, and particularly failed lumbar surgery syndrome. The purpose of this study was to examine whether the application of SCS causes any changes in pre- and post-procedural sleep, quality of life, and anxiety and depressive symptoms in patients with chronic pain.
Methods: The study was completed with 14 patients who were planned to undergo SCS due to treatment-resistant chronic neuropathic pain and who applied to the psychiatry outpatient clinic for pre-treatment consultation. Patients were evaluated twice, before treatment and 1 month after treatment. Patients were evaluated with the LANNS Pain Scale, Hamilton Depression Scale (Ham-D), Hamilton Anxiety Scale (HAM-A), Pittzburg Sleep Quality Inventory (PUKI), Quality of Life Scale Short Form (WHOQOL-Bref). Scale scores before treatment (pretest) and after treatment (posttest) were compared using a dependent two-sample t test.
Results: Depressive disorder was detected in 85.8% of the cases, anxiety disorder in 71.5%, and sleep disorder in 78.6%. The cases’ LANSS pain scale scores were 19.00±5.11 pre-treatment and 7.57±4.59 post-treatment, the difference being statistically significant (p=0.001). Significant differences were observed between pre- and post-test HAM-D, HAM-A, PSQI, quality of life (QoL) general health, QoL physical health, or QoL psychological health scores (p=0.002, p=0.014, p=0.002, p=0.002, p=0.002, and p=0.001, respectively) (Table 4). However, no significant differences were determined between pre- and post-test QoL social relationships or QoL environmental health scores (p=0.160 and p=0.831, respectively)
Conclusion: This study the application of SCS not only effectively reduced pain in treatment-resistant chronic pain, but also mediated significant improvements in sleep quality, anxiety, and depressive states.
