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[1]) 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[1]) Right Femoral greater Trochanter
LFLE (LE[1]) 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[1]) Right Femur Lateral Epicondyle
LFME* (ME[1]) 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[1]) 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[1]) 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[1]) Right Tibial Tubercle
LFAX (HF[1]) 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[1]) Right Fibula Apex
