Georges St. Pierre is officially on the road to recovery.

As revealed on his Facebook page, GSP has started the first phase of rehab following his ACL surgery last week.

First phase of rehab: in my room, putting in some work with the CPM (Continuous Passive Motion) machine.

If you’re wondering what the heck that contraption is, it basically moves his knee for him in a controlled range of motion.

Continuous passive motion (CPM) devices are used during the first phase of rehabilitation following a soft tissue surgical procedure or trauma. The goals of phase 1 rehabilitation are Control post-operative pain, Reduce inflammation, Provide passive motion in a specific plane of movement , and Protect the healing repair or tissue. CPM is carried out by a CPM device, which constantly moves the joint through a controlled range of motion, the exact range is dependent upon the joint, but in most cases the range of motion is increased over time.

It’s going to be a long road back, but so far, so good.
