Sling system. Positioning of subjects in the sling system for measurement on the SC. A laser beam (white line) was used to adjust and control the position of the subject. The upper and lower green lines help to identify the ventral and dorsal side of the pelvis, respectively. The purple line helps to estimate the angle between the lower extremities and the trunk. a Resting position in the slings: The centers of the lig. fibulare collaterale and of the caput humeri are in line with the beam. b SC: The centers of the lig. fibulare collaterale, of the trochanter major, and of the caput humeri are in line with the beam (pelvic lift)
