At the heart of Power Knee, you’ll find a motor that helps fill the absence of muscle power.
When you’re walking, you experience powered swing. When you’re standing up, you experience powered lift. When you’re ascending or descending, Power Knee provides the support and assistance you need to manage slopes and stairs. Simply summed up, you benefit both short- and long-term from symmetry, stability, and endurance.
