Altered wrist range of motion (ROM) and reduced muscle strength occur in individuals with LE; however, their combined utility for classifying LE remains unclear. Interpretable machine learning can help identify and explain biomechanical features associated with LE.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Objective<\/jats:title>\n                    <jats:p>This study developed and interpreted machine learning models to classify LE among assembly line workers using wrist ROM and muscle strength data, identifying the most influential biomechanical predictors using SHapley Additive Explanations (SHAP).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Data from 45 male assembly line workers (23 with LE, 22 without LE) were used. Predictor variables included wrist ROM (flexion, extension, radial deviation, ulnar deviation) and muscle strength (flexors, extensors, grip strength). Predictors were standardized within each training fold, and Gaussian noise augmentation was applied to training data. Four machine learning models were tuned using grid search and evaluated via repeated stratified 5-fold cross-validation. Discrimination, classification performance, and calibration were assessed, and SHAP was used for model interpretation.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>All four models achieved comparable discrimination (accuracy: 0.83\u20130.87; ROC-AUC: 0.91\u20130.92). Support vector machine showed the highest accuracy, whereas logistic regression showed the highest ROC-AUC. SHAP analysis consistently identified wrist radial deviation ROM as the most influential predictor across all models, with lower values linked to higher LE probability.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Interpretable machine learning models classified LE with good cross-validated discrimination using simple biomechanical measurements.
