Marker Name	Description	PlugIn Gait FullBody(39)	PlugIn Gait LowerBody(16)	Placement position
RF.Head	Right Back of the Head	√		Right Occiput
LF.Head	Left Back of the Head	√		LeftOcciput
LB.Head	Left Front of the Head	√		Left Temple
RB.Head	Left Front of the Head	√		Right Temple
C7	7th cervical vertebra	√		On the spinous process of the 7th cervical vertebra
T10	10th thoracic vertebra	√		On the spinous process of the 10th thoracic vertebra
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	Right finger	√		Just below the middle knuckle on the right hand
L.Shoulder	Left shoulder	√		On the acromio-clavicular joint
L.Upperarm	Left upper arm	√		On the upper lateral 1/3 surface of the left arm (Place asymmetrically with RUPA)
L.Elbow	Left elbow	√		On the lateral epicondyle
L.Forearm	Left forearm	√		On the lower lateral 1/3 surface of the left forearm (Place asymmetrically with RFRM)
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.
L.WristOut	Left wrist Left Wrist - Outer Side	√		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.
L.Finger	Left finger	√		Just proximal to the middle knuckle on the left hand

L.ASIS	Left Anterior Superior Iliac Spine	√	√	Left Anterior Superior Iliac Spine
R.PSIS	Right Posterior Superior Iliac Spine	√	√	Right Posterior Superior Iliac Spine (Located below the sacroiliac joint, where the spine connects with the pelvis)
L.PSIS	L.Right Posterior Superior Iliac Spine	√	√	Left Posterior Superior Iliac Spine (Located below the sacroiliac joint, where the spine connects with the pelvis)
R.Thigh	Right Thigh	√	√	Over the upper lateral 1/3 surface of the right thigh
R.Knee	Right Knee	√	√	On the flexion-extension axis of the right knee.
R.Shank	Right Shank	√	√	Over the upper 1/3 surface of the right shank
R.Ankle	Right Ankle	√	√	On the lateral malleolus along an imaginary line that passes through the transmalleolar axis
R.Heel	Right Heel	√	√	On the calcaneous at the same height above the plantar surface of the foot as the toe marker
R.Toe	Right Toe	√	√	Over the second metatarsal head, on the mid-foot side of the equinus break between fore-foot and mid-foot
L.Thigh	Left Thigh	√	√	Over the lower lateral 1/3 surface of the left thigh
L.Knee	Left Knee	√	√	On the flexion-extension axis of the left knee
L.Shank	Left Shank	√	√	Over the lower 1/3 surface of the left shank
L.Ankle	Left Ankle	√	√	On the lateral malleolus along an imaginary line that passes through the transmalleolar axis
L.Heel	Left Heel	√	√	On the calcaneous at the same height above the plantar surface of the foot as the toe marker
