CLAV
Clavicle
√
On the jugular notch where the clavicles meet the sternum
STRN
Sternum
√
On the xiphoid process of the sternum
RBAK
Right back
√
Anywhere over the right scapula,(This marker has no equivalent marker on the left side. This asymmetry helps the autolabeling routine determine right from left on the subject. Placement is not critical as it is not included in the Plug-in Gait model calculations.)
R.Shoulder
Right shoulder
√
On the acromio-clavicular joint
R.Upperarm
Right upper arm
√
On the lower lateral 1/3 surface of the right arm (Place asymmetrically with LUPA)
R.Elbow
Right elbow
√
On the lateral epicondyle approximating the elbow joint axis
R.Forearm
Right forearm
√
On the lower lateral 1/3 surface of the right forearm (Place asymmetrically with LFRM)
R.WristIn
Right Wrist - Inner Side
√
At the thumb side of a bar attached symmetrically with a wristband on the posterior of the right wrist, as close to the wrist joint center as possible
R.WristOut
Right Wrist - Outer Side
√
At the little finger side of a bar attached symmetrically with a wristband on the posterior of the right wrist, as close to the wrist joint center as possible
R.Finger

L.WristIn
Left wrist Left Wrist - Inner Side
√
At the thumb side of a bar attached to a wristband on the posterior of the left wrist, as close to the wrist joint center as possible. Loose markers can be used but for better tracking of the axial rotations, a bar is recommended.
