Swing Phase Lock 2
Swing Phase Lock 2
The Swing Phase Lock 2 Orthotic Knee Joint is designed for users who have difficulty controlling the knee during stance phase as in the situation of insufficiency of the knee extensors. This creates an unstable and unsafe gait pattern. Usually this also results in an asymmetric gait pattern with an increase in energy consumption. The SPL joint ensures, independent of any load, a locked knee prior to heel-strike and disengages automatically at the end of stance phase. This allows the user to learn to walk again with confidence, while the gait pattern approaches normal gait more closely by improving energy consumption, symmetry, gait velocity and reducing compensatory movements.
Mimics normal physiologic gait
Developed by Basko Healthcare, the Swing Phase Lock 2 (SPL2) uses a simple internal pendulum mechanism to lock and unlock the knee depending on the angle of the joint 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. This action is intended to mimic 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. This allows for a more normal gait pattern and helps prevent circumduction or hip hiking commonly seen in standard KAFOs.
