The proposed three-layer artificial neural network had 14 input nodes including hip range of motion (HROM), hip flexion moment (HMXFLEX), hip extension moment (HMXEXT), hip abduction moment (HMYABD), hip adduction moment (HMYADD), hip hip external rotation (HMZEXT), internal rotation (HMZINT), cup medialization (C-MED), cup inclination (C-INCL), cup anteversion (C-ANTE), horizontal offset (H-SET), vertical offset (V-SET), abductor lever arm (ABD-L), and subject age (Age).
