(D) The Shorthand Notation
The line description of a Step Model is read left to right, using the
following standard notations. All distances are in inches and all angles in
degrees.
R = right
L = left
S = step-line
C =
carry-line
A = aberration
St = stride-line
str = straddle-line
Wstr = walking-straddle
FO = (2) = foot offset given as 2 degree leg
angle
FA = 5L = 5 deg foot angle left
PO = <5>L = 5 deg push-off angle
left
SO = 15 = step-out-line = 15"
PS = {-2} = pelvic-stretch = -2",
(negative value means rear-stretch-line is decreased, a CCW rear-pelvic
joint rotation)
RL = [15] = rear-leg-line = 15"
L15{2}[15]str8: (2)L-2L-<4>R ( A straight left step.) = left foot
step-out-line = 15”, pelvic-stretch = 2", rear-leg-line = 15", straddle-line
= 8": (2deg leg angle) offset left (CCW), 2 deg foot angle left (CCW)and 4
deg push-off angle right (CW).
LA:2.5(36.5R)-16R = left foot aberration : 2.5 cm heel-point shift at
36.5 deg right (CW) from foot-line - 16 deg right (CW) foot-line rotation.
