Pain Neuroscience Education and Exercise for Chronic Nonspecific Low Back Pain

This randomized controlled study aims to investigate the effects of combining PNE with motor control exercises in individuals with CNSLBP who demonstrate central sensitization (≥28 points on the Central Sensitization Inventory). Participants are randomly assigned into two groups: the intervention group (motor control exercises + PNE) and the control group (motor control exercises only). Both groups participate in motor control exercises twice a week for 8 weeks, under the supervision of a physiotherapist. The intervention group additionally receives six PNE sessions once per week for six weeks. PNE sessions are delivered by a certified physiotherapist using interactive presentations and question-answer discussions. Assessments are performed pre- and post-intervention using the following tools: * Central Sensitization Inventory (CSI) to determine the presence and severity of central sensitization. * Numeric Pain Rating Scale (NPRS) for pain intensity. * Revised Neurophysiology of Pain Questionnaire (rNPQ) for pain knowledge. * Pain Catastrophizing Scale (PCS) for catastrophic thinking. * Pressure Pain Threshold (PPT) using a digital algometer. * Electromyographic (EMG) evaluation of trunk and lower extremity muscles using surface electrodes. * Spatiotemporal gait analysis using OptoGait and Ultium Insole systems. * Tampa Scale for Kinesiophobia (TSK) for fear of movement. * Roland-Morris Disability Questionnaire (RMDQ) for disability level. * Nottingham Health Profile (NHP) for quality of life. Data will be analyzed using SPSS version 27. Normality of distribution will be tested with the Shapiro-Wilk test. Depending on the distribution, either parametric (paired t-test, independent t-test) or non-parametric tests (Wilcoxon signed-rank, Mann-Whitney U) will be applied. Pearson or Spearman correlation analyses will be used where appropriate.
