FUNCTION LEVEL
IMPACT LEVEL
PRODUCT FUNCTION TERMS
K1 |
Has the ability or potential to use a prosthesis for transfers or ambulation on level surfaces at a fixed cadence. Typical of the limited and unlimited household ambulator. |
K2 |
Has the ability or potential for ambulation with the ability to traverse low level environmental barriers such as curbs, stairs or uneven surfaces. Typical of the limited community ambulator. |
K3 |
Has the ability or potential for ambulation with variable cadence. Typical of the community ambulator who has the ability to traverse most environmental barriers and may have vocational, therapeutic, or exercise activity that demands prosthetic utilization beyond simple locomotion. |
K4 |
Has the ability or potential for prosthetic ambulation that exceeds basic ambulation skills, exhibiting high impact, stress, or energy levels. Typical of the prosthetic demands of the child, active adult, or athlete. |
IMPACT LEVEL
LOW |
Daily walking and occasional non-jumping sports such as golf, hiking and racquet games. |
MODERATE |
Heavy heel walking, frequent or daily sports such as jogging and aerobics. |
HIGH |
Daily sports such as distance running, climbing, aerobics, and lifting and carrying heavy objects for vocational purposes. |
EXTREME |
Rigorous daily walking at high cadence, competitive athlete in track and field type events, has vocation that requires excessive jumping or loading of the prosthesis. |

PRODUCT FUNCTION TERMS
VERTICAL COMPLIANCE |
Vertical displacement creates shock absorption through e-carbon heel and carrier to reduce stress and trauma upon the residual limb, joints and lumbar region of the back during routine daily activities. |
E-CARBON HEEL |
Provides an Active Response and shock absorption to ground reaction forces and superior forward progression. |
SPLIT TOE |
Allows the foot to accommodate uneven terrain providing for medial/ lateral stability and security on varied surfaces. |
TRI-POD STABILITY SYSTEM |
Unique design taking advantage of our Truly Independent Heel and Toe design which provides efficient forward propulsion and stability on all terrain. |
TRULY INDEPENDENT HEEL & TOE |
A patented design where the heel and toe function 100% independently of each other which is more biomechanically correct and provides for a smoother rollover which efficiently absorbs shock. With optimal alignment eliminates the sensation of a “dead-spot” at mid-stance. Minimal muscular effort allows for more comfort while standing for prolonged periods of time. |
FULL LENGTH TOE-LEVER |
A full length toe lever promotes equal stride length allowing for a more biomechanically sound gait. It also promotes the amputee to spend equal time on both the prosthesis and sound side limb which provides and promotes stance phase stability. |
E-CARBON LAY UP |
A proprietary method of layering carbon to allow for a “proportionate reaction” to the weight and impact level of the amputee’s activity. The lay up provides flexibility where desired and impact resistance and strength where required. This allows the forefoot to deflect with ease allowing for a smooth and relaxed gait which requires less effort from the amputee. |
BIOMIMETIC |
Human made processes, substances or systems that imitate nature. Prosthetic systems use Biomimetics to imitate nature through the geometry as a main source of stability of joint centers, not just the mechanical or fluid resistance of the joints creating more efficient methods of control. |
DYNAMIC TIBIAL PROGRESSION |
The process of forward motion is aided by carbon foot heel components which contribute to the effortless forward motion (tibial progression) of the limb. The process is enhanced through the unique shock absorption characteristics and very efficient energy management of e-carbon mix. |
MULTI_AXIAL ROTATION |
Two or more axis of rotation at the ankle, Anterior-Posterior, Medial-Lateral and transverse planes which provide additional stability and natural ankle motion on all walking surfaces. |
FLEXIBLE KEEL |
The keel section of a prosthetic foot that deflects under load without significant energy return, but stable on uneven ground situations. |
DYNAMIC RESPONSE |
The elastic property of a component (carbon fiber or similar) is designed to deflect under load and has the ability to store and return significant energy. |
STANCE FLEXION |
A part of the prosthetic knee which simulates concentric and eccentric contraction of the quadricep muscles to act as a brake and dampen the prosthetic system absorbing loads. |
STANCE CONTROL |
A term used to describe the supplement of a less limited amputee needing support from the knee control. It refers to extra security in the event of a misstep or when the amputee is rested during weight bearing, adding stance stability. A knee which can be partially bent, then as weight is shifted onto the prosthesis the stance control stops it from collapsing, permitting them to complete the step safely. |
