The Swing Phase Lock 2 (SPL2) uses a
simple internal pendulum mechanism to
lock and unlock the knee depending on the
joint angle in the sagittal plane. During gait,
the device locks just prior to heel strike for
support during stance and unlocks the knee at
heel-off in preparation for swing, mimicking
the normal physiologic action of the knee
extensors. Because the mechanism is position
dependent, it does not rely on heel loading
or cabling as in other designs, allowing for
a more normal gait pattern and preventing
circumduction or hip hiking.
