Exploring the complex interplay: Correlation between pronated foot and pelvic inclination, femoral anteversion, quadriceps angle, tibial torsion and talus head position in asymptomatic adults

Background: Pronated foot potentially induces alterations in lower limb kinetics, influencing gait patterns and elevating energy expenditure.Nevertheless, a comprehensive understanding of the connection between pronated foot and other static alignment factors remains lacking.Therefore, this study aimed to establish correlations between pronated foot and pelvic inclination, femoral anteversion, Q-angle, tibial torsion, and talus head position.Method: This observational study involved 100 individuals of all genders, aged 18-30, with a Foot Posture Index (FPI) score of +6 or higher.Outcome measure evaluations were performed for pelvic inclination, femoral anteversion, Q-angle, tibial torsion, and talus head position.SPSS 25.0 software was used to analyze the correlation between the FPI score and all variables, employing Pearson's correlation and one-way ANOVA followed by post hoc Tukey tests.Results: FPI exhibited a significant positive correlation with the Q-angle (r=0.267,p=0.007), while correlations with other variables were nonsignificant.Strong positive correlations were observed between tibial torsion and talus head position (r=0.696,p=0.000).Notable differences were identified between FPI scores of 6-8 and 9-10/11-12 across these variables using one-way ANOVA.A regression model utilizing Q-angle as a predictor revealed a statistically significant relationship with FPI (R=0.267,p<0.05).Conclusion: The study revealed significant connection between FPI and Q-angle, indicating possible link between foot posture and lower limb alignment.However, while certain alignment factors showed significant differences across FPI score groups, others didn't exhibit
