PS1 Pronation / Supination CPM Device

The PS1 Forearm Pronation / Supination CPM is a portable device for delivering the proven benefits of CPM treatment to the forearm. Continuous passive motion has demonstrated over the years its ability to help patients regain postoperative range of motion and avoid the negative effects of immobilization. By gently moving the forearm through a controlled pronation/supination range of motion, the PS1 can effectively help prevent postoperative stiffness of the distal and proximal radial-ulnar joints and the soft tissue connecting the radius and ulna.

Range of motion is adjustable from 0 to 90 degrees of pronation/supination. A torque isolating feature ensures anatomically correct motion over the entire range of motion which will  reduce increased stress on the joints and increases patient comfort. The safety feature of two reverse-on-load force setting options allow the force of motion to be customized for optimum treatment results.
post surgery arm rehab
Durable, lightweight construction and ease of use makes the PS1 ideal for both hospital and in-home environments. The unit is easily attached to the patient, and can be worn comfortably for extended periods of time to ensure the full benefits of CPM treatment. Patient compliance is further enhanced by the PS1’s portability. A rechargeable motion controller and convenient shoulder sling allow the patient to be fully ambulatory during treatment.


Do not use the device if any of the following are present: untreated or uncontrolled infection, unstable fractures or hemorrhaging.

Immediate postoperative management after the following, where indicated:

  • Distal radius fractures (when stable)
  • Fractures of the radius and ulna
  • Fractures of the radial head
  • Fractures associated with the humerous and ulna
  • Surgical reduction or excision to treat radio-ulnar synostosis
  • Disruption of carpal and radio-ulnar joints

Healing In Motion

Research continues to demonstrate that moving a limb or joint aids rehabilitation and leads to better outcomes. By combining active physical therapy along with a Continuous Passive Motion (CPM) device, it is possible to significantly increase joint range of motion.

PS1 OrthoAgility® Pronation Supination Forearm CPM

The PS1 uses anatomically correct motion from 0 to 90 degrees of pronation-supination.
