The Swing Phase Lock 2 is an updated version of Fillauer’s most popular stance control orthotic joint. New features include an extended wear bumper, security stops at 15 and 32, teflon bushings for longer wear, and a PEEK high wear insert. Like its predecessor, the Swing Phase Lock 2 features an enhanced position-dependent pendulum design and multiple locking positions for added safety, providing increased stability for patients with tentative gait. The joint comes with either bilateral or unilateral uprights for easy donning. It is the only design available for use with rehab knee orthoses and also works with any orthotic ankle design.
