Prolonged sitting and sedentary behavior, common among office workers (often referred to as Office Syndrome, OS), are significant risk factors for the development of non-specific low back pain (NSLBP). These issues may be related to key muscles of the back and hip, specifically the hip flexor (Psoas major, PM) and the quadratus lumborum (QL), which are deep muscles critical for movement and spinal support. Previous studies have shown that prolonged sitting can lead to excessive tension in the PM
