JT22<br />

Polycentric Knee Joint with Pneumatic Swing Phase Control.<br />

1 <strong>Prosthetics</strong><br />

1.4 Prosthetic Knee Joints<br />

Pneumatic swing phase control with a seperate adjustment of flexion and extension. With a weight limit of 150 kilograms<br />

and a design for mobility levels 3. The technology behind this is two pole curves that can easily be adjusted by simply turning<br />

the extender wheel. On „S“, the knee joint is set for high stability. On this setting, the center of rotation is still in the stable<br />

range. On the „D“ setting the JT22 allows for a more dynamic gait. The center of rotation falls more in the dynamic range.<br />

Depending on the prosthesis wearer‘s condition, he or she can use the polycentric JT22 for the majority of the rehabilitation<br />

process. High stability is a top priority at the start of rehab and then when the prosthesis wearer gets more mobile, a prosthetist<br />

can quickly and easily adjust the joint for a more dynamic gait.<br />
