From: New fluoroscopic imaging technique for investigation of 6DOF knee kinematics during treadmill gait
Top: Average speed of the knee and duration of the stance phase of gait on treadmill at four different walking speeds. Bottom: Peak kinematic values of the knee during different intervals of the stance phase. F/E: flexion (+)/extension(-); IR/ER: internal(-)/external(+) femoral rotation; A/P: anterior(+)/posterior(-) femoral translation; ML: medial(-)/lateral(+) femoral translation; SD: standard deviation.
