PMI 20-90


  • Adjustable arm positioning
  • Personal therapy system
  • Bilateral and universal
  • Lightweight, breathable and comfortable
Scope of Application
  • Rotator cuff repairs
  • Bankart lesion
  • Impingement syndrome shoulder
  • Adhesive Capsulitis (frozen shoulder)
  • Reverse shoulder athroplasty
  • Shoulder replacement
  • Capsular plication surgery
  • Rotator cuff tendonitis

Directions for Assembly
  • Attach wrist and bicep cuff to the arm board
  • Threat shoulder strap and waist strap through the D-rings
  • Shoulder and waist straps can be shortened by cutting the straps and re-attaching the y-hook and loop fasteners
Directions for Use
  • Slip narrow shoulder strap over neck and lay arm on arm board. Cushion will rest on side of neck for comfort. Tighten strap to desired comfort level.
  • Adjust wide waist strap to desired comfort level.
  • Adjust bicep and wrist cuff to desired comfort level.
  • Attach hose to the pump and the brace; connection can be found behind the plastic cover on either side of the brace. Plug in power cord to an outlet. Once connected, push power button.
  • Set the “Degree of Abduction” knob to desired setting.
  • Select desired “Therapy Time” interval.
  • To remove hose from orthosis, press metal release tab.
  • To deflate, turn off the pump at 20 degrees or apply constant pressure to black release valve behind the plastic cover while applying pressure to the arm board.
  • Universal

PMI 20-90 Shoulder Therapy System

Superior Features

Adjustable Abduction

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

Continuous Passive Motion

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

PMI 20-90 Pump 

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

Postoperaive stiffness after rotator cuff tear repair is more correlated to pain and less to functional results. In our series, after 16 months of follow-up there was a persistent significant deficit in passive external rotation and in the constant score in the “immobilization” group, with no difference in healing.


Thus the rehabilitation protocol which results in better tendon healing by preventing postoperative stiffness, has not yet been identified. Our results suggest that early passive motion should be allowed, because the functional results were better with this type of rehabilitation. A short period of immobilization could nevertheless be beneficial to protect the repair without compromizing the functional results.

Does early motion lead to a higher failure rate or better outcomes after arthroscopic rotator cuff repair? A systematic review of overlapping meta-analyses

The majority of meta-analyses found significantly better range of motion with early motion up to a year postoperatively for forward elevation and up to 6 months for external rotation.



The current highest level of evidence suggests that early-motion rehabilitation after rotator cuff repair results in superior postoperative range of motion up to a year.
