Reinforcing The Prosthetic Socket - Ottobock 7E10 Helix3D Gebrauchsanweisung

INFORMATION
Stance phase resistance is a new aspect in the prosthetic fitting after amputations in the pelvic area. Therefore,
please make the adjustment very carefully and permanently check whether the resistance can be increased
further! It is important for the prosthesis wearer that he can put weight on the prosthesis as long as possible
during the stance phase.
The stance phase on the moving hip joint is possible because of the high resistance and should be considered
the goal of the walking training, even if the prosthesis wearer might feel uncomfortable in the beginning. Please
take the time to understand this important procedure and to explain and practice the procedure with the pros­
thesis wearer. Only then the prosthesis wearer will be able to fully benefit from the advantages of this product.
