Straps are suitable for a majority of the adult population and can be placed directly on the skin for the

close contact, or on top of the clothing for comfort. If worn over clothing, it is advisable to wear relatively

tight-fitting clothes.

The motion trackers are provided with a code

indicating segment position.

‘L’ or ‘R’: left or right side of the body.

Segment: An abbreviation of the segment name.

While the straps are not labelled, the dimensions

give an indication of their intended locations.

 It is recommended to begin by putting on the top.

 Since the sternum and shoulder trackers are attached to Velcro patches on a zip-fastening t-shirt, it

is advised to secure this garment before attaching the upper arm straps.

 For the arms, legs and pelvis: Straps should first be placed (tightly) onto the limb in question, fasten

the tracker in place then wrap the remaining length of the strap tightly around the limb and fasten

using the Velcro tab.

 It is necessary to have assistance for positioning the motion trackers of the shoulder blades after

the zip on the vest has been secured. It is also advisable to have assistance for accurate positioning

of the tracker at the pelvis, while the wearer (or second assistant) wraps the remaining length of the

strap around the waist.

 Check that the Straps are fastened tightly enough to the body.

To do this, the subject wearing the straps should walk, run or perform sample movements to be

measured. If the straps become loose, re-tighten them and repeat the check.

NOTE: When tightening the straps, pull the strap from the center of the length rather than at the

end!
