Swing Phase Lock
Swing Phase Lock or SPL orthosis has got a unique hinge knee joint to support paresis or partial paresis of knee extensors in e.g. Post Polio, MS, peripheral paresis/paralysis or neurological damages (not applicable in cases with knee- or hip joint contracture or spasticity). SPL joint locks with in-built mechanism right before the heel contact and unlocs at the end of midstance enabling knee flexion in swing phase. Swing Phase Control � joint (on the inner side of the knee) softens the excessive swinging motion and it�s resistance is adjustable. SPL-joint has a satellite wire controller with three functions:
1.automatic control
2.free movement (e.g. when entering a vehicle)
3.lock (e.g. when standing)
