Biomechanical Effects of Prefabricated
Foot Orthoses and Rocker-Sole Footwear in
Individuals With First Metatarsophalangeal
Joint Osteoarthritis -
correct answer ✅Results:
The orthoses had minimal effect on spatiotemporal or kinematic
parameters, while the rocker-sole footwear resulted in reduced
cadence, percentage of the gait cycle spent in stance phase, and
sagittal plane hip range of motion. The orthoses increased peak
pressure under the midfoot and lesser toes. Both interventions
significantly reduced peak pressure under
the 1st MTPJ, and the rocker-sole shoes also reduced peak pressure
under the 2nd through 5th MTPJ and heel.
When the effects of the orthoses and rocker-sole shoes were
directly compared, there was no difference in peak pressure under
the hallux, 1st MTPJ, or heel; however, the rocker-sole shoes
exhibited lower peak pressure under the lesser toes, 2nd through
5th MTPJ, and midfoot.

Questions And Answers
Discussion:
indicate that both interventions were effective at reducing peak
pressure beneath the first MTP joint, which may be one of the
mechanisms responsible for their apparent beneficial effects in the
treatment of OA affecting this joint. However, they appear to
achieve this through different mechanisms.
The prefabricated orthoses in this study were modified
by the addition of a cut-out section beneath the 1st MTS, as
described by Welsh et al (8). The rationale behind this approach is
to facilitate 1st ray plantarflexion, thereby allowing the proximal
phalanx to dorsiflex on
the 1st Met head and minimize joint compression
during propulsion. -
correct answer ✅However, the gait analysis component of the
study by Welsh et al found no differences in 1st MTPJ dorsiflexion
when orthoses were worn, despite participants reporting a
reduction in symptoms.
Our in-shoe plantar pressure data suggest that orthoses may
instead achieve their apparent beneficial effects by redistributing
load away from the 1st MTPJ, possibly by shifting it toward the

medial longitudinal arch during midstance and toward the lesser
toes during propulsion.
In our study, stride length was not significantly altered when
wearing the
rocker-sole shoes. However, there was a reduction in cadence and a
trend (P=0.08) toward reduced velocity, both of which may reflect
the adoption of a "cautious" gait pattern that has been shown to
result in reduced sagittal plane hip motion during gait

EFFECT OF FOOTWEAR ON BALANCE -
correct answer ✅The results of this study indicate that dynamic
balance assessed during a single-leg jump landing task is better in
bare feet than in standard running shoes, and is not significantly
different between Vibrams and standard running shoes.
These results are consistent with the hypothesis that filtering or
masking of sensory input by footwear can affect dynamic postural
stability.
