The marker model has a total of 36 retro-reflective markers attached bilaterally to anatomical landmarks during the static measures （without exoskeleton） and 28 markers at the dynamics measures （with exoskeleton）. The main difference between others kinematic models and the described adapted model was the placement of the three markers in the back thigh and the other three in the back calf, what allowed removing the hip, thigh, knee, tibia and ankle markers. The proposed adapted marker model could be an effective tool to validate the joint movement and velocities of those wearable exoskeletons that at present have been developing.展开更多
