Abstract
Assessing finger joint loading is essential to the prevention of work-related musculoskeletal disorders of the hand and fingers. This study aimed to evaluate the effect of muscle action on joint loading during dynamic finger pressing tasks using an open-source musculoskeletal modelling platform. Eight participants performed submaximal dynamic index finger pressing tasks while maintaining a nominal vertical target force of 10 N. Kinematic and force data were used to develop and assess an inverse dynamics link segment model and a musculoskeletal model. Although musculoskeletal model results for metacarpophalangeal joint compression evaluated statically (34.92 ± 1.53 N) and dynamically (34.80 ± 4.40 N) did not differ, changes in anterior-posterior shear and compression throughout the motions identify where the current open-source model is able to provide valuable insight into the assessment of risk of developing MSD during sub-maximally loaded dynamic pressing tasks.

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
