Density plots showing the variations in the joint angles at the hip of 4 sitting positions, stratified by gender: A) benjangkapradit prostration; B) sitting on a step stool; C) left-monk (left hip); and D) left-monk (right hip). The external and internal rotations of the hip are the positive and negative values, respectively. The dashed lines signify the median value of the hip joint angle. The P values were computed with the Mann–Whitney U test
