4 Gait training
Prosthesis wearers can optimally benet from the Helix
3D
Hip Joint's features only if they are properly instructed
and trained in walking. The following aspects are especially important for the gait training:
1. The prosthesis wearer walks with the hip joint exed at heel strike; during the stance phase, the hip joint
is then extended controlled by resistance.
Unlike with conventional hip joints, the prosthesis wearer does not have to perform quick backward tilt of the pel-
vis. Hip joint extension can be controlled by resistance during the entire stance phase thereby reducing abrupt
backward tilt of the pelvis upon weight bearing. Especially to experienced prosthesis wearers this is unfamiliar in
the beginning and has to be practiced consciously.
2. The expansion springs facilitate initiation of the swing phase. Pelvic tilt can therefore be reduced.
Inform the prosthesis wearers that they have to perform only signicantly reduced pelvic tilt to swing the prosthe-
sis forward, because the Helix
3D
Hip Joint is brought into exion by the expansion springs. The prosthesis wearer
must learn how far the prosthetic foot swings forward when the prosthesis is lifted by the expansion springs. This
is very important especially for waking down stairs, in order to be able to precisely place the foot.
