The task of wall painting produces considerable risk to the workers, both male and female, primarily in the development of upper extremity musculoskeletal disorders. The aim of this study was to investigate the influence of gender, work height, and paint tool design on shoulder muscle activity and exerted forces during wall painting. 

Results: For both genders, the high working height imposed greater muscular demands compared to middle and low heights.

Conclusion: These findings suggest that, if possible, avoiding work at extreme heights will reduce fatigue onset and subsequently assist to prevent and mitigate potential musculoskeletal shoulder/neck injuries
