Background & Aim: Genu varus is one of the most common injuries of the lower limb, which affects posture control by creating internal torque on the ankle and foot joints. The complication of Genu varus is accompanied by the biomechanical change of the lower limb during walking and running. The aim of the present study was to evaluate the effect of using agility shoes on running kinetics in individuals with genu varus before and after fatigue protocol.
Methods & Methods: This study was a case-control type. In this study, 14 individuals with genu varus and 15 healthy ones as control aged 20-30 years participate. Using the Bertec Force platform, ground reaction forces were recorded during running before and after the fatigue protocol. The normality of data distribution was confirmed using the Shapiro Wilk test. Two­ way analysis of variance with repeated measures was used for statistical analysis. All the analyzes were performed at a significance level of 0.05 using SPSS 25 software.
Results: In both groups, the fxto values during the pre-test was larger than that post-test (p=0.000). Also, the fyhc values in the pretest was larger than the posttest (p=0.000). Moreover, the fypo values in the pretest were larger than the posttest (p=0.000).
Conclusion: In general, running kinetics were similar in individuals with genu varus compared with healthy controls before and after fatigue protocol while using agility shoes.
