  • In addition to preparing a list of markers, consider attaching markers to a subject and viewing them in the capture volume as part of the design process.
  • Aim to have at least three markers for each required segment: two markers will give a line, but three markers will enable the calculation of a plane.
  • Place markers on known anatomical landmarks to ensure repeatability between subjects.
  • When you create your marker set, it is often useful for both the labeling skeleton template and for your biomechanical model to have markers placed on joint axes. However, for the most efficient labeling, avoid sharing markers between segments.
  • If possible, avoid placing markers where they will be subject to unwanted movement (for example, on soft tissue), and/or where they will be occluded by the subject's movement during movement trials.
