Abstract
Background: Linemen should be evaluated regarding the presence of musculoskeletal symptoms to guide the identification of risk factors for development of work-related musculoskeletal disorders (WMSD) and to allow the implementation of preventive measures. Objective: To assess the occurrence of WMSD symptoms among linemen working at a regional branch of an electricity distribution company, to investigate whether there were differences in the proportions of symptomatic workers among the functions performed, and to perform a preliminary survey of the main risk factors present. Methods: Thirty male linemen (mean age 38.1±5.5 years) were evaluated, divided into three teams according to their job function (Live Line Linemen, LLL; Maintenance/Emergency Linemen, MEL; Commercial Linemen, CL). Musculoskeletal symptoms were identified on a body map, qualified using the McGill questionnaire and quantified using a numerical scale. The DASH questionnaire was also applied to evaluate the impact of the shoulder symptoms on the workers' performance. Results: Seventy percent of the linemen presented at least one musculoskeletal symptom in the shoulders, back or knees. All of the LLL team presented musculoskeletal symptoms and these workers had the highest scores in the DASH questionnaire (28±15). Sixty-seven percent of the MEL team presented symptoms, and their DASH score was 8±11. Fifty percent of the CL team presented symptoms, but none of them had shoulder symptoms. The proportion of workers with shoulder symptoms was related to their job function (p=0.02). Conclusions: A high proportion of the linemen presented symptoms which varied according to the occupational activity. Interventions are needed to reduce the risk of WMSD among the linemen evaluated.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
