Gait training

Prosthesis wearers can optimally benefit from the Helix
and trained in walking. The following aspects are especially important for the gait training:
1. T he prosthesis wearer walks with the hip joint flexed 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. T he expansion springs facilitate initiation of the swing phase. Pelvic tilt can therefore be reduced.
Inform the prosthesis wearers that they have to perform only significantly reduced pelvic tilt to swing the prosthe­
sis forward, because the Helix
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.
