The Plié Microprocessor Knee

To provide individuals with a more natural experience of mobility, Freedom Innovations examined biological norms to establish performance criteria for the new Plié® 2.0 with microprocessorcontrolled swing and stance. By integrating high-performance processing capabilities and a cutting-edge hydraulic system, the Plié 2.0 is the most responsive MPC knee ever developed.

Rapid Reaction to Gait Changes
A finely tuned control system enables the Plié 2.0 to respond to ambulatory stimuli within 10 milliseconds. Consequently, users can stay in stance phase longer, take smaller steps and change walking speeds more fluidly.

Advanced Stumble Recovery Capabilities
A proprietary position sensor and patent-pending load cell built into the frame of the Plié 2.0 provide input to advanced algorithms utilized by the microprocessor to control stance and swing, and stumble recovery parameters.

Optimized Swing Flexion Resistance
The hydraulic cylinder changes resistance in response to a highly reactive, solenoid-activated spool valve that opens and closes in 10 milliseconds. Resistance is controlled by pressure and position rather than speed.

Low-Profile and Ultra-Lightweight Design
The distance between the lever arm and joint center is minimized and the hydraulic cylinder is inverted, bringing its center of gravity closer to the knee. The result is in the lowest profile MPC knee available.

Durable and Reliable
Featuring a high-performance aluminum frame, the Plié 2.0 knee exceeds ISO standards for structural integrity. In addition, its electronic components are sealed for water resistance.

Plié 2.0 Setup Wizard
An intuitive and easy-to-use Plié 2.0 Setup Wizard assesses each user's unique gait dynamics to ensure optimum performance. Typically requiring less than 20 minutes for a complete setup, the Wizard guides the process and automates the settings, making the fitting process highly efficient.
