Right Glenohumeral Joint
Waist Markers
Note that the waist markers are the key markers in modeling the pelvis bone, which is the major segment governing the other subsequent skeleton segments.

Placement Description
LCAJ (LA
[1]
)
Thorax
Left Clavicle-Acromion Joint
Ask the subject to stretch both arms towards the side (T-pose), then palpate top of each shoulder for the protruding bone. The prominence is usually located at the end of the corresponding clavicle bone just before where the upper arm starts.
RCAJ (RA
[1]
)
Thorax
Right Clavicle-Acromion Joint
LHLE

Right Humerus Medial Epicondyle
LUA
Upper Arm
Left Upper Arm
Ask the subject to stand in T-pose while placing the marker. Palpate to find the groove between the triceps muscles where skin movements are relatively minimal.
RUA
Upper Arm
Right Upper Arm
Hand Markers
For best results, place the three hand markers so the created shape is asymmetrical (avoid isosceles shape) and unique from the marker arrangements on the other hand. Since the wrist markers have defined placement — along the wrist axis — introduce small amount of positional offset to the LHM2 and RHM2 markers.

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.
