•With its evolution, the improved C-Leg offers
additional benefits for users of high MG2, MG3
and low MG4 –primarily more safety and
improved dynamics
•An enhanced stumble recovery minimizes the
risk of falling
•Furthermore, stance release and standing with a
flexed knee are now a lot easier and therefore
noticeably improve the user’s flexibility and
freedom of movement
