15.2.2 Wrist
Start with the subject's shoulder in abduction at 90 degrees and elbow flexed at 90 degrees, such that
the forearm is close to full pronation. As shown in figure 9, attach the distal endblock to the dorsal
surface over the third metacarpal with the center axis of the hand and endblock coincident. While
fully flexing the wrist (figure 10) extend the goniometer to position 2 (figure 8) and attach the proximal
endblock to the forearm so that when viewed from the dorsal plane the axes of the forearm and
endblock are coincident. The wrist may now be flexed or extended, radial or ulnar deviated with the
goniometer freely sliding between positions 1 and 2.
NOTE: If monitoring both movements of flexion/extension and radial/ulnar deviation with a varying
position of pronation and supination, the 2 endblocks of the goniometer should be mounted close to
the wrist joint to minimize crosstalk. To do this the goniometers type no. SG65 or SG75 must be
used.
