Research protocol and results from System Anthropometry Laboratorys three-dimensional investigation of the lumbarpelvis linkage system are presented. A stereoradiographic system measures three-dimensional coordinates of implanted targets in the skeletal system of an unembalmed cadaver seated in a wooden seat conforming to Air Force specifications. The cadaver is experimentally positioned to obtain three-dimensional data on lumbar extension, flexion, and lateral sidebending motions. Data are analyzed to provide a screw axis description of the instantaneous axis of rotation for each change of position. In addition, position vectors are calculated that describe locations of the bones in the lumbarpelvic linkage system and a point on the screw axis closest to the origin of the bone frame of reference. The data are presented in three-dimensional coordinates measured in a laboratory with a spatial accuracy of approximately or minus 0.03 cm. The extensive references to measurement and measurement techniques studies offer a listing not presented elsewhere in the literature, or in other reviews of the literature, and with particular application to systems anthropometry, from the fields of anthropometry, osteology, kinematics, and three-dimensional measurement techniques.
