Investigating forward head posture and its influence on postural alignment among desk-based employees

Abstract

Background: Forward Head Posture is a common musculoskeletal issue increasingly observed among desk-based employees, particularly those engaged in prolonged sitting and frequent use of digital devices. It’s linked to musculoskeletal problems such as neck pain, headaches and decreased quality of life. this study examined the relationship between forward head posture and various postural deviations, including body alignment deviation, head tilt, shoulder misalignment, pelvic tilt, knee asymmetry and foot asymmetry. Objective: to explore the connection between forward head posture and postural deviations in desk-based employees through cross-sectional study. Methods: Ninety-eight desk-based employees exhibiting symptoms of forward head posture were assessed using two mobile applications: the assessment of postural and ergonomic conditions for workers application and the forward head posture app. Preliminary statistical analysis applied to the collected postural alignment parameters for identifying data outliers. Data were analyzed using Pearson correlation coefficients, multiple regression analysis and factor analysis to identify key factors influencing forward head posture. Results: Forward head angle (FHA) was highly correlated with body alignment deviation (r = 0.931), head tilt (r = 0.877), shoulder alignment deviation (r = 0.883) and computer &mobile usage (r = 0.819). Regarding to factor analysis body alignment deviation was the most significant predictor of FHA. Conclusion: FHP is strongly linked to poor upper body alignment and prolonged use of digital devices. Body alignment deviations and other biomechanical factors had a major effect on forward head angle and total posture with a regression model explaining 95.8% of the variance in forward head angle.
