Abstract

Relationship between ankle strategy and knee flexion torque in people with genu varum during landing
Abstract
Introduction: genu varum is a common deformity among athletes and non-athletes’ individuals. One of the most important influencing risk factors during landing is knee flexor torque that has a huger effect on the person with varus knee. The aim of this study was to investigate the relationship of variable Rate of Loading (ROL) and knee flexion moment in individuals with varus knee for examination of ration between this biomechanical risk factor and ankle strategy.
Material and Methods: Fourteen-man athlete with varus knee (Age: 26±3.5, Hight: 172±4.59, weight: 74. ±4.5) in single group participated in this study. Each participant done correct drop landing for three-time under force plate and motion capture recording. variability outcome calculations were performed using MATLAB b2016R software.
Results: The results of the of Pearson correlation coefficient indicated that the variable ROL has a positive significant relationship with the variable of Maximum flexor torque of the knee (P≤0.05). Accordingly, alongside of ROL reduction based on special ankle strategy during landing knee flexion moment had been reduced.
Conclusion: The results of this study showed that the ROL controlling strategy in the ankle can affect the flexor torque of the knee and reduction the effect of this biomechanical risk factor.
