Nonspecific chronic low back pain (NSLBP) is one of the most common musculoskeletal disorders worldwide, associated with consequences such as disability, reduced quality of life, work absenteeism, and economic burdens on healthcare systems. This type of back pain typically lacks a specific pathological cause and is influenced by various factors, including individual, occupational, psychological, and environmental elements. Impaired core muscle function, reduced proprioception, poor balance, and decreased muscular endurance are among its key characteristics.



Given the limited effectiveness of pharmacological treatments and patients' inclination toward non-invasive approaches, exercise therapy has gained attention as an effective intervention. Dynamic Neuromuscular Stabilization (DNS) exercises, aimed at improving motor control and core stability, have shown positive outcomes in reducing pain and enhancing patient function. Additionally, combined exercise programs incorporating strength, aerobic, and flexibility components have also proven effective in improving functional outcomes.



This study aims to compare the effectiveness of two exercise approaches—DNS and combined training—in reducing pain and improving function among male office workers with NSLBP.



The research is applied in nature, quasi-experimental, cross-sectional in design, and uses a within-subject (pre-test–post-test) format. It is conducted as a randomized controlled clinical trial with 33 participants randomly assigned to three groups.
