Lower Extremity Markers
The joint center of the knee and the ankle is modeled at the midpoint of the lateral and medial joint markers (FLE/FME and FAL/TAM). Assuming that center of the femoral head aligns with the center of the acetabulum, its virtual location is modeled using markers on the pelvis segment (posterior and anterior iliac spine markers). The lower extremity segments are modeled along these three virtual locations.
Labels	Related Segment	Anatomical Location	Placement Description
LFTC (GT)	Pelvis	Left Femoral greater Trochanter	Place the markers on left and right side of the hip, where you can palpate the hip joint or the most lateral prominence of the greater trochanter.
RFTC (GT)		Right Femoral greater Trochanter
LFLE (LE)	Upper Leg	Left Femur Lateral Epicondyle	Place the marker on the lateral prominence of the knee joint axis. More specifically, the marker should be placed on the femur epicondyle. You may need to ask the subject to flex and extend the knee few times to locate the axis.
RFLE (LE)		Right Femur Lateral Epicondyle
LFME* (ME)	Upper Leg	Left Femur Medial Epicondyle	Place the marker on the Medial prominence of the knee joint axis. Ask the subject to flex and extend the knee few times to locate the knee axis.
RFME* (ME)		Right Femur Medial Epicondyle
LTH	Upper Leg	Left Thigh	Place the markers at the front center of the thigh near the midline. This marker is placed for distinguishing left and right side of the skeleton. For best results, slightly offset the height of right and left marker to introduce an asymmetry.
RTH		Right Thigh
LSK	Upper Leg	Left Superior Knee	Place the markers on the shin bone near the midline of the lower leg. This marker is placed for distinguishing left and right side of the skeleton. For best results, slightly offset the height of right and left marker to introduce an asymmetry.
RSK		Right Superior Knee
LTTC (TT)	Lower Leg	Left Tibial Tubercle	Place the marker about 2-3 cm below the knee cap bone. This marker should be placed on the most anterior point of the tibial tuberosity.
RTTC (TT)		Right Tibial Tubercle
LFAX (HF)	Lowe Leg	Left Fibula Apex	While standing, place the markers approximately 5 cm below the LFLE and RFLE markers. This marker should be placed on the lateral prominence of proximal end of the fibula.
RFAX (HF)		Right Fibula Apex
