Fig. 3From: Three-dimensional motion analysis of ten common Asian sitting positions in daily living and factors affect range of hip motionsDensity plots showing the variations in the joint angles at the hip of 3 sitting positions, stratified by BMI (overweight, BMI ≥ 23 kg/m2): A) benjangkapradit prostration; B) squatting; and C) standard leg-cross. The flexion and extension 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 testBack to article page
