PMI 20-90 Benefits

Therapeutic Range of Motion

The PMI 20-90 Shoulder Therapy System allows for patient-controlled continuous passive motion (CPM) therapy as directed by the surgeon during the ongoing recovery process. The therapeutic range of motion feature of the PMI 20-90, unavailable in similar devices, was designed to assist in post-operative pain management and prevention of adhesive capsulitis.

Improved Patient Compliance and Comfort

The PMI 20-90 was developed by shoulder specialists to combat the significant problem regarding patient compliance and comfort. Varying degrees of abduction has been difficult to achieve during the recovery process but is often preferred by the patient to help with comfort. Surgeons have found that the desired degree of abduction varies significantly from patient to patient during their recovery. The PMI 20-90 gives patients the versatility they need, allowing for safe and easy patient-controlled adaptability.


The PMI 20-90 is an innovative, new device consisting of a brace and pump that work in tandem to offer 20 to 90 degrees of adjustability, giving the surgeon 70 degrees of treatment options in the immediate post-operative course to protect tenuous or larger repairs. The surgeon can customize the degree of abduction in the operating room and then transition the PMI 20-90 to different degrees of abduction during the recovery phase, depending on the patient’s needs.

Better Surgeon Outcomes

The PMI 20-90 provides surgeons with the outcomes they demand – even if the patient has limited access to post-operative physical therapy. Surgeons have seen a lack of patient compliance with some braces which can be uncomfortable and cumbersome following surgery. Many patients tend to discard their brace and ultimately do not properly protect their repair to assist in their recovery process due to the inability to perform daily tasks while wearing the brace. The function of the PMI 20-90 ultimately leads to superior results and patient satisfaction.

Billing Education

Surgeons who purchase the PMI 20-90 will be educated on how to properly bill third-party payors through their own practice for the approved L3960 PDAC code. This education will equip clinics to replace stock-and-bill partnerships with their own billing process.

Superior Features

Continuous Passive Motion

The CPM feature allows a range of motion in the immediate postoperative phase. This feature improves the brace’s overall function and recovery results.

Adjustable Abduction

The adjustable abduction feature allows variable positioning. This dramatically improves patient comfort and the ability to sleep following surgery.

PMI 20-90 Pump

The technologically developed PMI 20-90 pump allows for patient-controlled CPM therapy as directed by their surgeon.
