Need to step up your bar game prowess? Let’s dive into Dart Thrower’s Motion

To talk about the Darth Thrower’s Motion (DTM), we have to introduce the 8 tiny bones that make up the anatomical wrist. These 8 bones articulate with the radius, ulna and metacarpals of the hand to make up the wrist and its motion.

The DTM is a two-part motion that involves the wrist moving from extension and slight radial deviation, to wrist flexion and ulnar deviation. The DTM occurs in the scapholunate plane, at the mid-carpal row – between the first (proximal) and second (distal) row of bones.

Ok, but why is the DTM important?
The DTM is particularly important during functional wrist motion. The vast majority of our daily tasks occur in this scapholunate plane, meaning the DTM is utilized! This is particularly important for anyone who has been immobilized in a brace or cast for an extended period of time – especially if your wrist was included! During the immobilization of these joints, the ligaments that stabilize those 8 tiny bones become less mobile or elastic, contributing to wrist stiffness. The DTM is important therapeutically, as it is a gentle, safe introduction to movement at the wrist. So next time you are walking through one of our clinics, don’t hesitate to try your hand at darts and the dart thrower’s motion!
