: For the movements shown in the illustration, there is a risk of falling because they may deac­
tivate the stance phase flexion resistance.
► CAUTION! Provide the patient with support (e.g. parallel bars) and have them carefully test at
what load stance phase flexion resistance is deactivated. Then discuss with the patient how
these movements can be avoided or supported. Examples:
: To avoid a hard ground contact of the prosthetic leg with strong extension (e.g. curb)
→
immediately followed by knee flexion moment, adjust the stride length so the movement is
carried out with the sound leg.
: To avoid a quick, forceful step forward with the prosthetic leg (e.g. jump) and
→
strong hip extension moment at heel strike immediately followed by knee flexion
moment, adjust the stride length so the movement is carried out with the sound leg.
: To walk backwards safely, make sure that no load is placed on the prosthetic forefoot
→
with simultaneous hip and knee flexion moment, or walk with the prosthetic knee joint
locked.
