BioStampRC and Body Orientation during Motion. (a) Three planes of the body in anatomical position: frontal plane (blue), transverse plane (green), and sagittal plane (red). (b) Placement of BioStampRC on volar surface of the forearm. (c) Top view of horizontal adduction and abduction of arm with subject in supine position. Motion is performed with straight arm in the transverse plane and about the BioStampRC y-axis (d) Side view of flexion and extension of arm with subject sitting straight. Motion is performed with straight arm in the sagittal plane and about the BioStampRC z-axis. (e) Front view of vertical abduction of arm with subject sitting straight. Motion is performed with straight arm in the frontal plane and about the BioStampRC z-axis
