participation in volleyball grows, it is necessary to have effective prevention programs for knee injuries in volleyball athletes. Core stability is defined as the ability to control the position and movement of the trunk over the pelvis. 5 Anatomically, the region between the diaphragm, abdominal muscles

and the pelvis in that posture. In the late 19th century, Vierordt ( 1864 ) was likely the first to quantitatively measure postural sway during standing; he employed a device that measured the sway of the head. Neither Borelli nor Vierordt measured the forces on the feet, although they acknowledged

following the manufacturer’s guidelines. To define the foot, shank, thigh, and pelvis, 14-mm retroreflective markers were attached to the right limb at the following locations: first and fifth metatarsal heads, medial and lateral malleoli, medial and lateral femoral epicondyles, and bilaterally to the

Retroreflective markers were placed on the right lower extremity and pelvis based on a previously published marker convention. 26 A 1-second static calibration trial was recorded

clinical setting along with gait testing by clinicians. This is particularly important because turning is a complex motor task that involves multisegmental rotation and temporal coordination of head, trunk, and pelvis while maintaining postural stability of the whole body. Previous research reported that

The cameras of a hybrid Vicon (Centennial, CO) MX T-Series and Bonita motion capture system surrounded two force platforms (AMTI, Watertown, MA) located in the center of the lab. The total length of the two platforms was approximately 1
