Instruction Manual from Otto Bock HealthCare

Both knee joints are equipped with an innovative, load-dependant brake mechanism. The brake mechanism engages when the heel is loaded. It stabilizes the prosthesis and achieves a high degree of security during the entire stance phase. The braking mechanism releases automatically when the forefoot is loaded, and the swing phase can be initiated easily and harmoniously. Unphysiological movements, such as hip hike are minimized with this system and this helps to create a more secure, harmonious gait.
