A fundamental revision of the hydraulic swing phase control creates a whole new feeling of comfort and stability for the wearer. The significant reduction in the amount of force required to initiate the swing phase and new, progressive damping result in greater freedom of movement. Whether it is a relaxed stroll through the park or a brisk city walk to the next appointment, the new 3R80 offers control at low, medium, and even brisk walking speeds. The 3R80 easily adapts to changes in walking speed while minimizing gait deviations.
A Confident Step
Wearers must be able to rely on their prosthesis, especially in the stance phase. The 3R80’s rotary hydraulic responds to ground reaction forces throughout stance phase, building up hydraulic resistance which prevents involuntary flexion of the joint and provides more security. The level of resistance can be easily adjusted to the requirements of the user, and enables yielding – variable knee flexion under load.
The 3R80’s patented function is particularly advantageous on uneven surfaces, on slopes, and when walking down stairs. It creates a high level of stance phase control and thus boosts the confidence of the prosthesis wearer – an important emotional factor.
The 3R80 offers you 4 adjustment options for stance and swing phase control. As usual, the flexion and extension resistance can be adjusted easily and independently. Fine stance phase damping adjustments and changes in response behaviour are easy to make by gradually turning the adjustment rings.
If needed, an additional spring can be added effortlessly to increase the extension assist force. The spring, adjustment aid, and tube adapter are conveniently included with your knee purchase.
In order to guarantee proper biomechanical processes, Otto Bock recommends using the following feet with the 3R80: Dynamic Motion 1D35, Trias 1C30, C-Walk® 1C40, Axtion® 1E56, Luxon® Max DP 1E42/43 and Advantage DP2 1E50/51.
