Aims and background: Moving on steep surfaces is a challenging task in daily life, especially when walking, which poses challenges for the human locomotor system, especially for those with neuromuscular injuries or disease. Therefore, the aim of this study was to compare plantar pressure variables in healthy students and students with genu valgum during walking on a slope surface.
Materials and methods: The research was quasi-experimental, causal-comparative and applied research model. The samples of this study includes 15 girls with geno valgum (with the between medial malleolus distance of 3.90±0.44 cm) and 15 girl healthy knees (with the between medial malleolus distance of 0.73±0.29 cm). Plantar pressure variables were evaluated in 10 areas of the foot on the sloping surfaces level of 0, ±8%, ±10%, ±20% in the stance phase of gait was examined. Two-way ANOVA with repeated measure was used for statistical analysis. Significant level was set at 0.05.
Findings: Maximum pressure was significant fifer between groups only in the areas of the Tarsal 1 and metatarsal 2-4 and lateral rear food on the slope of +8, -15 and -20 with values in genu valgum group compared with healthy ones. Changes in the center of pressure of the foot on the positive and negative slopes of 8 and 15 in the geno valgum group compared to the healthy in medio-lateral direction significantly trended toward negative values.
Conclusion: The results showed that changes in the center of pressure increase the amount of foot pronation by increasing the slope and decrease the amount of ankle pronation by increasing the negative slope; Therefore, slopes of -20, -15 and -8 can be suggested to improve the distribution pattern of plantar pressure in adolescent girls with genovalgum knee. However, further study is warranted.
Key words: genu valgum, gait, slope, Plantar pressure variables, adolescents
