Exploring the usability and perceived benefits and barriers of portable lift assist devices among paramedic workers
Bibliographic record
Abstract
Patient lifting can expose health care workers to musculoskeletal disorder (MSD) risk factors. Portable lift assist devices may reduce exposure during lifting, however limited evidence on user feedback and efficacy is available to inform purchase decisions. Therefore, we tested the efficacy of two portable lift assist devices relative to a manual lift when lifting an individual from the floor. Participants lifted an actor from the floor using a manual technique and by using two lift assist devices, either an inflatable bladder or a mechanical device. Ratings of perceived exertion demonstrated that the lift assist devices decreased or maintained perceived exertion relative to the manual lift. Semi-structured interviews provided context where perceived benefits of the devices (i.e., decreased exertion and MSD risk) outweighed barriers (i.e., added time to call). The results of this study can inform stakeholders making decisions about lift assist devices purchases.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
