ShoulderSphere® Instructions for Use
Correct position: ensure your wrist is relaxed and has complete contact against the plastic
splint while being securely strapped in by the elastic strap. Relatively tight engagement is
necessary in order to optimize the rotator cuff workout. Make sure there is no wiggle room
between your wrist and the splint. This also avoids undue stress against the plastic splint,
which may cause breakage.
The easiest way of putting on the ShoulderSphere® is to place it on top of your hand --
PALM facing UP - and gently cradle it, making sure that the strap is wrapped securely,
particularly the part at wrist level.
Incorrect position: note in the image below how the wrist is tense and flexed against the
splint. There is a large gap between the splint and the wrist, which creates undue three-
point contact stress against the plastic splint. This will break the plastic splint. There
should be no wiggle room in-between the skin and the plastic splint. Incorrect posture
prevents an optimal rotator cuff workout.
