What's the correct way to position my CPM machine?

In order for your CPM therapy to be effective, your limb must be properly positioned in the CPM machine.

If your CPM Machine is for your knee:

Make sure your knee is lined up with the unit's hinge and your foot is rested firmly, yet comfortably, against the footplate.  Use your machine on a flat, firm surface, such as the floor or your bed.  You may prop your back up for comfort, as long as it doesn't exceed a 30 degree angle.
