Musculoskeletal symptom survey among mason tenders.
BACKGROUND
Low back pain (LBP) constitutes a major problem in construction. The magnitude and musculoskeletal injury characteristics in certain construction trades have been studied extensively. Musculoskeletal research targeting mason tenders is limited. High physical demands of the job primarily contribute to an increased risk of LBP experienced by these laborers.


METHODS
A symptom survey was conducted to determine the magnitude and musculoskeletal injury characteristics among the mason tenders, and to identify work-related activities perceived by them as contributing to their disorders.


RESULTS
The findings revealed that 82% of the mason tenders experienced at least one musculoskeletal symptom in the last year. LBP was the most frequently reported symptom (65%). Due to LBP, 12% of the laborers missed work and 18% of them visited a physician. Bending or twisting the back, working in the same position or in pain, and heavy lifting they perceived as the most problematic work-related activities. The vast majority of the laborers requested job-safety training.


CONCLUSIONS
The mason tenders experienced high prevalence of LBP. To address the problem a model for primary prevention of LBP was developed and implemented in the trade. The model incorporated ergonomic principles, hazard recognition, and problem solving in the training curriculum for the union instructors teaching apprentices the trade-specific skills.
