B – Becker Model 9005 – SafetyStride

The SafetyStride is a mechanical stance control orthotic knee joint that utilises a low-profile cabling system to automatically unlock itself at the end of stance phase. The key feature of the SafetyStride is its ability to resist knee flexion at any angle.
Does not require full 180 degree extension to resist knee flexion in stance phase.
Joint unlocks at terminal stance, and re-engages during swing phase.
