During the terminal stance
phase, increased hip extension at the amputated limb (p > 0.
A properly designed spiral wheel must compensate for the variations in a human step to produce a steady backward force.
They found significant abnormal GRF parameters during the terminal stance
the maximum value of generated ankle power during terminal stance
(maximum value of positive ankle power; APMax index), expressed in W/Kg.
On the other hand, the decrease in maximum plantar flexion in terminal stance
was not found significantly different in NIFA and CPIFA groups, but it was also not different in TD and NIFA groups.
During terminal stance
(30-55% of the gait cycle), the internal knee moment was flexor again.
The terminal stance
and pre-swing (TP) phase was identified from the point where the heel stopped contacting the floor to the point where there was no contact between the foot and the floor.
High-frequency stimulation was also delivered to the hip extensors during loading to provide extra extension moment for moving the body forward, while low-frequency stimulation was used during mid and terminal stance
to maintain hip extension.
We divided the stance phase by initial contact, loading response, midstance, terminal stance
, and pre-swing.
Timing of the PPAFO assistance was dictated by four regions with different functional gait requirements: (1) loading response, (2) midstance, (3) terminal stance
through preswing, and (4) swing (Figure 2) .
Shank angle during terminal stance
was measured during 30% to 50% of stride.
At terminal stance
, the prosthetic knee undergoes rapid knee flexion in preparation for the SW phase.
