Welcome to the next generation of stance control orthotic knee design, the SPL2

Developed by Basko Healthcare, a Fillauer affiliate in the Netherlands, 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 prevents circumduction or hip hiking commonly seen in standard KAFOs.

The Swing Phase Lock 2 has four modes of operation controlled by a proximal remote push-button switch:

1. Free motion
2. Automatic Lock/Unlock
3. Manual Lock
4. Manual Unlock

The different modes allow the patient to select automatic lock for walking, unlock for sitting, lock for standing or free motion for driving in a car or riding a bicycle.

The Swing Phase Lock 2 (SPL2) must be used with the Swing Phase Control (SPC) Joint which uses friction and a spring to regulate knee flexion during swing phase. The SPL2 is designed to be mounted laterally and the SPC medially. Both use standard 3/4" (20mm) sidebars.
