Abstract
BACKGROUND: Slide sheets (SS) are friction-reducing devices used during patient-handling tasks. A modified SS position (modSS), with the slider placed beneath the regular bedsheet, may decrease a caregiver's workload and reduce low back injuries, as the SS could remain in place for longer periods o f time, thus reducing patient re-positioning frequency. OBJECTIVE: To investigate the efficacy of modSS use on back muscle activity, pulling force, and perceived effort during lateral patient-handling tasks, and determine whether lumbar electromyography (EMG) correlates with perceived effort (RPE) during such tasks. METHODS: Ten females completed 9 lateral patient-handling tasks with 3 simulated patients (45 kg, 68 kg and 91 kg) and 3 SS conditions (absent, normal, modSS). Outcomes included peak pulling force, back muscle EMG, RPE and subjective reports of low-back discomfort and preference. RESULTS: ModSS use was as effective as or better than normal SS use at reducing back muscle EMG, pulling force, RPE and perceived discomfort in all 9 conditions, when compared to no SS (p< 0.05). The relationship between RPE and EMG was moderately strong (r= 0.75). CONCLUSION: ModSS use may reduce caregiver injury rates, as it reduces biomechanical and perceived demands associated with lateral patient-handling tasks at least as well as normal SS use, if not better.

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
