propulsion. She had a marked scoliosis
and lordosis. Observing the frontal plane,
she showed left shoulder drop and right
shoulder elevation. Genu valgum was seen
bilaterally. She also had an extreme pelvic
tilt with the right side being higher, and
exhibited tibial varum bilaterally, with a
greater manifestation on the right. She
presented with flexible pes planus on the
left foot and rigid pes cavus on the right
foot. She exhibited an equinus gait that
showed an early heel off, and a shortened
stride length with a hard heel strike.
A biomechanical study was conducted
utilizing the EMED® Pedobaragraph
and Gait Matt II®. Using the EMED
pedography two-dimensional system, the
left foot demonstrated a center line of
force traversing more medial in pronation
through the foot, and propelling out the
hallux. The right foot struck with less
pressure, and the center line of force
moved more lateral in a slight supination
with the pressure loading through the
metatarsal heads, then propelling through
the hallux. In the EMED three-dimensional
view the peak of the center of force line
was flat and showed an apropulsive line
of force from her heel to hallux on the
left foot, and on the right foot, the center
line of force raised to a peak pressure at
approximately the submetatarsal 2 and then
traversed through the hallux. The right
foot had less surface contact pressure
