Motion Capture Process: Subject Preparation

The analysis of biomechanics is a major component in evaluating athletic performance. During this process, several reflective markers are placed on the skin overlying specific bony landmarks of the legs, pelvis, and upper body. These markers provide information on the locations of the body's joints and major segments. The CHP developed a unique upper extremity kinematic model to allow for reliable measurements of gleno-humeral (shoulder joint) rotations relative to the shoulder girdle. Since adequate representation of joints and bones depends on accurate marker placement, members of the CHP's staff, who are highly trained in human anatomy and kinesiology, routinely undergo marker clinics to maintain quality assurance.
