Head posture and musculoskeletal pain in computer using office workers in Sri Lanka

A cross-sectional study was conducted with 198 computer-using office workers in two regional offices in Sri Lanka. The head posture angles (neck flexion, head flexion, and craniocervical) were captured using photogrammetry and calculated using ImageJ software. The musculoskeletal pain (neck, shoulder, and back) in the previous 24 hours and >3 months (chronic pain), duration of computer usage, age, and sex were recorded using a self-administered questionnaire.
