ِDear Sungjae

we are using our custome made harness. but because we don't use motion capture system i have no idea about your problem. use the sensors of robot to measure the joint angles. you may use ganiometers or other sensors for your problem.

best regards

I have looked online at the harnesses you mention --it would appear that the Maine anti-gravity harness fits over the pelvis thus making it difficult to place markers on ASIS   or PSIS -- also the strap around the thigh makes the placement of a thigh marker difficult too--

The photos on BonMed  did not show a child but it looked as though this harness was around the chest -- this may not obstruct marker placement but may be less comfortable as it may 'ride up' during use.

I have used electrogoniometers to measure hip, knee and ankle motion during gait -- application proved v time consuming

I suggest that you look at the work of Cappozzo et al  --  they were using a pointer that had markers mounted on the shaft  and placing the tip of the pointer on the location of interest and using the coordinates of the shaft markers to create a virtual marker in  the static trial --

Hi,

Maybe you can try with the harness made by Biodex for their Offset BWS System
