OptiFlex is a continuous passive motion (CPM) device designed for use with individuals with lower extremity disabilities. This device is engineered with an extra-wide carriage to accommodate knee replacements or other knee injuries or disabilities. The unit offers progressive range of motion (ROM), an Oscillation Zone that replicates the benefits of active physical therapy protocols, a Fast Back mode that enables the knee to spend more time in working ROM by accelerating through non-working ROM, and a Comfort Zone button which allows the unit to continue working the affected limb at a reduced flexion angle limit when the pain threshold is reached. Additional features include context-sensitive help and a nine-language interface, backlit display and buttons for visibility, hyperextension (-10 degrees) to full knee flexion (120 degrees), and a carrying handle. A patient kit is also included. OPTIONS: Optiflex CPM Kit, AutoFlex CPM Kit, Danniger CPM Kit, Breg/Optiflex CPM Kit, 34-inch strap kit, storage rack, and a bed mount. DIMENSIONS: 37 inches long. WEIGHT: 28 pounds.
