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.)
RSHO
Right shoulder
√
On the acromio-clavicular joint
*RUPA
Right upper arm
√
On the lower lateral 1/3 surface of the right arm (Place asymmetrically with LUPA)
RELB
Right elbow
√
On the lateral epicondyle approximating the elbow joint axis
*RFRM
Right forearm
√
On the lower lateral 1/3 surface of the right forearm (Place asymmetrically with LFRM)
RWRA
Right wrist marker A
√
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
RWRB
Right wrist marker B
√
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
RFIN
Right finger
√
Just below the middle knuckle on the right hand
LSHO
Left shoulder
√
On the acromio-clavicular joint
*LUPA
Left upper arm
√
On the upper lateral 1/3 surface of the left arm (Place asymmetrically with RUPA)
LELB
Left elbow
√
On the lateral epicondyle
*LFRM
Left forearm
√

LWRA
Left wrist marker A
√
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.
LWRB
Left wrist marker B
√
At the little finger 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.
LFIN
Left finger
√
Just proximal to the middle knuckle on the left hand
LASI
R.ASIS
√
√
Left anterior superior iliac spine
RASI
L.ASIS
√
√
Right anterior superior iliac spine
LPSI
R.PSIS

RPSI
L.PSIS
√
√
Right posterior superior iliac spine (immediately below the sacro-iliac joints, where the spine joins the pelvis)
