Within-patient comparison of dynamic joint function of healthy and arthritic knees including range of motion, flexion, and extension torque in children with JIA. Within-patient comparison of dynamic joint function of healthy and arthritic knees including range of motion, flexion, and extension torque in children with JIA. Intra-individual comparison of ROM, flexion and extension torque of healthy and arthritic knees in children with JIA reveals significant differences in all parameters of dynamic joint function. Boxes represent the interquartile range (25-75th percentile), lines within the boxes the medians. Bottom and top bars indicate the 10th and 90th percentile, respectively.
