Introduction: Changes in dynamic foot loading, high
or low plantar arch and shoe cushioning have been
risk factors associated with many overuse injuries in
lower limbs of runners1,2,3,4. Foot alignment is another
important risk factor, which may alter plantar distribution
pattern of the foot5. However, the literature is still a lack
of evidence on educational strategies of these risk factors
to change plantar pressure, especially as prevention of
the risk of injury. Further studies are needed to investigate
the strategies to dynamic plantar pressure change in
runners based on the risk factors most associated with
foot injuries. Therefore, the purpose of this study was to
investigate the influence of educational biomechanics
strategies for correcting the plantar pressure pattern in
feet regions different of recreational runners.
Materials & Methods: Twelve recreational runners were
evaluated: 24 feet total assessed (45.4±8.1 yr, 69.6±14.0
kg, 1.68±9.2 m). The plantar pressure was evaluated
by pressure platform system during static posture. All
runners exhibited a heel strike pattern of running. Soon
after this evaluation, the runner was invited to participate
in 2 lectures with biomechanical themes of the risk factors
associated with lower limb injury. The first lecture is on
pain and impact overload in feet and the second on foot
posture and shoe types. Each lecture with 20 consecutive
minutes was followed by 10 minutes for questioning with
the speaker. Two weeks after the lectures, all the runners
were re-evaluated. Maximal force, peak pressure and
contact area were evaluated over the lateral and medial
rearfoot, midfoot and forefoot. The data were processed
in a custom written Matlab function. Dependent variables,
pre and post lecture, were compared by paired t-test
(p<0.05).
Results: Variables related to maximum force in midfoot
was reduced post lecture (pre: 19.4±15.2; post:
15.2±11.4, p=0.04), peak pressure increased over
forefoot (pre:1409.0±264.6; post:1508.2±208.2, p=0.03)
and the lateral (pre:276.7±50.1; post:309.6±58.7, p=0.01)
and medial (pre:287.1±53.8; post:316.9±61.5, p=0.01)
rearfoot. Contact area showed no significant difference
over the lateral and medial rearfoot, midfoot and forefoot
(pre and post lecture).
Conclusion: The educational biomechanics lecture for
correcting the plantar pressure pattern in feet regions
different of recreational runners was not effective, leading
to increased peak pressure on the forefoot and rearfoot
(medial and lateral). These findings help to understand
the need of the physiotherapist to train with exercise the
better distribution of plantar load.
