The aim of this study was to determine the effect of an eight-week
corrective exercise program on plantar pressure distribution pattern in
adolescents with genu varum deformity. 12 male adolescents aged between
13 and 17 with genu varum deformity were assigned in experimental group
and 12 subjects without this deformity were selected as the control group.
Foot plantar pressure measurement system was used to measure foot
plantar parameters in stance phase of walking. Experimental group
received an eight-week corrective exercise program. A pretest and posttest
was conducted in the beginning and at the end of the study. The data were
analyzed by independent and dependent t tests (P<0.05). Pretest results
showed that the experimental group had a greater plantar peak pressure
under the toes 2-5 areas in comparison with the control group (P=0.018).
Moreover, the center of foot pressure in the exterior-interior lateral
direction in the heel contact phase had more supination (P=0.049).
Corrective exercises reduced peak plantar pressure in the toes 2-5 region in
the experimental group (P=0.022) while no significant difference was
observed in the amounts of the center of foot pressure in the interior-exterior lateral direction (P􀒹0.05). According to the findings of this study, it
can be concluded that corrective exercises improves plantar pressure
distribution pattern among individuals with genu varum as well as the
walking pattern.
