ClinConnect Summary
Thirty-nine passive-reflective markers of 14 mm in diameter were placed on the participant (Figure 1) according to the landmarks set of the plug-in full body model. An 8-camera motion capturing system (VICON, Nexus 2.0 Inc., Oxford, UK) and 2 force plates (AMTI, Advanced Mechanical Technology, Inc., Watertown, USA) mounted under the walkway were utilized for gait analysis and recorded 100 frames per second simultaneously. All the systems were calibrated before the experiment.
