Study summary

The aim of this study is to determine the effects of different types of low back pain on pain intensity and quality of life in patients with failed low back surgery syndrome.

The study will include 200 patients with failed lumbar spine surgery syndrome who present to the physical therapy and rehabilitation (FTR) outpatient clinics of Konya Beyhekim Training and Research Hospital with complaints of lower back pain lasting at least 3 months.

Patients will be evaluated in a single session. The Visual Analog Scale (VAS), Pain Catastrophizing Scale (PCS) will be used to determine the patients' pain level and impact, the Roland-Morris Disability Questionnaire (RMDQ) will be used for functionality assessment, and the SF-36 score will be used for quality of life assessment.

To determine the type of pain:

Those with pain levels above the cutoff value on the DN4 (Douleur Neuropathique 4 Questions) pain scale will be diagnosed with neuropathic pain.

For nociplastic pain affecting the musculoskeletal system, a diagnosis of nociplastic pain will be made according to clinical criteria and grading scores.

Those who do not meet these criteria will be classified as having nociceptive pain.
