Introduction & Objective

Plantar pressure is acted between the foot and the support surface during everyday locomotor activities. Information derived from plantar pressure distribution symmetry is important in gait and posture research for diagnosing lower limb problems, footwear design, injury prevention and other applications. Hence, this paper was aimed to review plantar pressure distribution symmetry in adolescence girls with genu varum, genu valgum and healthy during gait.

Materials and Methods

The research was quasi-experimental, causal-comparative and applied research model. Subjects included 45 girls with genu valgum, genu varum and healthy girls. The plantar pressure values were examined in 10 anatomical areas of plantar pressure on 0, ±10% slopes in the gait stance phase. Two-way analysis of variance with repeated measures was used for statistical analysis. Significance level was equal to 0.05.


No significant difference was observed in the symmetry variables of plantar pressure distribution in 0, ±10 slopes in the genu varum, genu valgum and healthy groups. While the healthy group at the 1,5 metatarsus and tarsus on the slope (surface slope) and the 5th metatarsus on -10% slope, and genu varum group at maximum tarsus pressure in all three levels and maximum tarsal 2-5 pressure only on the slope and maximum plantar pressure on the 10% slope and the maximum 1st plantar pressure on -10% slope for the genu valgum group have better symmetry.


The results show that genu varum and genu valgum anomalies affect the symmetry indices of plantar pressure distribution in adolescent girls; so that adolescent girls with knee deformities have less symmetry in the 5th metatarsus and tarsal 2-5 than healthy people. Therefore, the slope (surface slope) can be suggested to improve the plantar pressure distribution pattern in adolescent girls with genu varum and genu valgum knees. However, more studies are needed in this area.
