Dear colleagues, in our department we do it this way: The patient first takes a ball in his hand and lightly cups it. Now the wrist is positioned without any abduction. Since the forearm is now floating, a foam plate should be placed underneath the distal forearm to compensate. During the recording, the patient should squeeze the ball as hard as possible. The ball must provide a certain amount of resistance, otherwise there will be no significant increase of stress on the SL-ligaments and no persevering dissociation of the bones. Format 18/24 / focal distance ca. 1,05m, central ray postitioned on the SL-joint. Cool trick that I just learned: If you don't have a special expansive high tech ball - just grab an apple:
