the step table.
For each step and stride some parameters are calculated and shown in the
corresponding step and stride table.
Steps and strides can be annotated by toggling the toolbar button. Steps will be
shown using dark blue dimension lines, while strides will be shown using dark green
dimension lines. Only annotations for the current consecutive feet with the same
orientation are visible. During replay steps and strides not belonging to the current foot
are annotated in faint colors.
Step
A step is defined from the heel strike of the first foot to the heel strike of the second
foot. The following parameters are calculated:
Distance: the distance in millimeter between the two heel strikes
Duration: the time in seconds between the two heel strikes
Velocity: velocity in meter per seconds based on the calculated distance and
duration
Stride
A stride is defined from the heel strike of the first foot to the heel strike of the last foot.
There are two types of parameters calculated from a stride: gait cycle parameters
relative to the first foot and support parameters relative to the middle foot.
The following gait cycle parameters relative to the first foot are calculated:
Distance: the distance in millimeter between the two heel strikes
Duration: the time in seconds between the two heel strikes
Velocity: velocity in meter per seconds based on the calculated distance and
duration
Stance duration: the time in seconds that the first foot makes contact with the floor.
This is from the heel strike phase until the toe off phase
Swing duration: the time in seconds that the first foot doesn't touch the floor. This is
from the toe off phase of the first foot until the heel strike phase of the last foot
The following support parameters relative to the middle foot are calculated:
heel-heel base of support distance: the distance in millimeter from the middle foot to
the line determined by the first and last foot
single support duration: time in seconds that only the middle foot makes contact
with the floor
double support duration: time in seconds that two feet make contact with the floor
together. This can happen with the first and middle foot and/or the middle and last
foot.
double float duration: time in seconds that no foot makes contact with the floor. This
can happen between the first and middle foot and/or the middle and last foot.
