People with transfemoral amputation spend 50% more energy when moving than people without amputation. Besides, they have to do balancing knee, hip and trunk movements on slopes. These balancing movements increase the back pain experienced in more than 60% of prosthesis wearers, which can significantly and negatively affect their quality of life. Besides, approximately 50% of prosthetic users have been observed to fall annually, and 19% of these users have reported that their condition is serious enough to require treatment. 76% of people with amputation who stated that they avoided certain activities and environments stated that the reason for this was fear of falling. 

SYMBIONIC LEG helps to restore a more symmetrical walking pattern and minimizes the need for balancing movement with just-in-time automatic active ankle movements. As a result, SYMBIONIC LEG helps reduce pain, fatigue, and damage to other parts of your body while also reducing the risk of falling.

Opinions about the SYMBIONIC LEG are very positive. Popular Science Magazine has awarded the SYMBIONIC LEG the “Best of What’s New” Award, and users and prosthetists reported that there was an increase in confidence, which brought them a more natural ability to move.

Act naturally with a gentle and lifelike walking style.


Safe ground clearance, surface adaptation, and easy swing motion start to eliminate the need for gait changes and help restore a natural gait.

Stacey Pryor’s life has changed forever since she lost her right leg above the knee 13 years ago in a motorcycle accident. Her first prosthesis  mekanikti  was mechanical until he tried SYMBIONIC LEG. Stacey instantly felt that SYMBIONIC LEG was “a part of it”. From this new situation, ”It immediately kept up with me. “I regained my leg,” she said. Stacey noticed that her previous leg used to slow her down. The load on the healthy side of the hip, knee, and wrist disappeared overnight. She stopped having a circumduction gait and realized that she could now walk straight up the slopes without changing the way she walked. Stacey’s mother after seeing walking with SYMBIONIC LEG said that she had a smooth and natural walking. In June 2012, Stacey joined the first Texas Rangers game after a 12-year break, just a month after the SYMBIONIC LEG was fitted. Although she was a very “big fan”, she completely abandoned this event because it was too tiring for her to move between the car park and the long road from the stadium, all the ramps and stairs, and the crowd. Now, the biggest challenge was finding tickets.

Act more naturally on uneven   surfaces with more confidence in yourself.

Posture control and smart surface adaptation provide greater stability on everyday surfaces such as grass, slopes, and uneven floors, eliminating the need to concentrate on each step.

Randy Tweten hit him in a boat while swimming in Puget Sound. The propeller smashed his right leg and never saw this leg again. Randy since then has walked and fell with many different types of prostheses. As an amputee, after staggering and falling for 32 years, his body was very damaged. The injury list includes staples on the head, injuries to the arm, a broken wrist, and countless bruises, scratches, and cuts. It’s normal for Randy to be afraid of certain surfaces, such as grass, rocks, and gravels, and often find excuses to escape activity after having had so many accidents. Everything changed when it switched to SYMBIONIC LEG. “I don’t think of the surface or obstacles I’m walking on Randy said, thanks to his powered toe lift. This is not a problem for me”. And although he staggered “several times” thanks to the Stumbling Safety, he has not yet fallen. His mood is renewed   and he is more active than ever.Now he is discovering new ways to put himself in new challenges every day. He no longer thinks about the painful falls he used to. He even smiles and says, “The only pain I experience now is from using the muscles I forgot I had.”
