Work-related musculoskeletal disorders disorders (WMSDs) are increasingly prevalent among desk-based employees due to prolonged sitting, inadequate workstation design, and insufficient postural awareness in modern workplaces. This study investigates the effectiveness of a combined ergonomic redesign and physiotherapy-based corrective intervention in reducing musculoskeletal disorders pain, improving functional capacity, and lowering ergonomic risks among sedentary office workers. A quasi-experimental pre-post design was employed involving 60 employees who underwent an 8-week integrated intervention program. Baseline assessments included the Rapid Office Strain Assessment (ROSA), Visual Analog Scale (VAS) for pain, and Neck Disability Index (NDI), alongside postural alignment measurements. The ergonomic redesign involved individualized adjustments in chair height, monitor position, lumbar support, and keyboard-mouse alignment, while the physiotherapy component consisted of targeted stretching, strengthening, posture correction exercises, and neuromuscular re-education. Post-intervention findings revealed statistically and clinically significant reductions in pain and disability, with VAS scores improving from moderate to mild ranges and NDI scores showing substantial functional recovery. ROSA scores indicated a shift from high-risk to low-to-moderate-risk workstation configurations, and postural analysis demonstrated meaningful improvements in head-forward posture and shoulder symmetry. The results highlight that the combined intervention was more effective than ergonomic redesign alone, supporting the need for integrative approaches in occupational rehabilitation. The study concludes that addressing both environmental and physical determinants of WMSDs is essential for optimizing musculoskeletal disorders health among desk-based employees. Practical implications include the incorporation of routine ergonomic audits, structured physiotherapy-based corrective programs, micro-break scheduling, and organizational policies promoting active posture management. These findings reinforce the value of multidisciplinary workplace health strategies and offer a comprehensive framework for preventing and managing WMSDs in sedentary occupational settings.
