The Impact of a Highly Adjustable Chair and Office Ergonomics Training on Musculoskeletal Symptoms: Two-Month Post Intervention Findings
Bibliographic record
Abstract
The office ergonomic intervention is a longitudinal pre-post quasi-experimental design, with three study groups: a control group, a group receiving an office ergonomic training program, and a group receiving both the ergonomic training and a highly-adjustable ergonomic chair. The chief health outcome measure for this study is an overall bodily pain score constructed from a self-administered “scorecard”. The study population is from the claims processing and customer service departments of a large (5,000 employees) medical services company. 251 participants had enrolled in the study. Post-intervention, the chair-with-training group had a lower level of pain throughout the day compared to either the training-only or the control groups. This effect was calculated using a separate ANOVA model for each day of the week, and significance or borderline significance was obtained in each run (p = 0.001, 0.015, 0.04, 0.001, 0.05 on Monday-Friday). There was no significant effect for the training-only group.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
