LOWER EXTREMITY MALALIGNMENT AND LINEAR RELATION WITH Q ANGLE IN FEMALE ATHLETES

Résumé 0

"Lower extremity alignment has been proposed as a risk factor for acute and chronic lower extremity injuries. The aim of this study was to determine the extent to which select lower extremity alignment characteristics are related to the Q angle. One hundred and thirty female athletes were examined for navicular drop, Q angle, genu recurvatum, femoral anteversion, T-F angle, tibiofemoral angle, dorsiflextion, hip internal and external rotation and general join laxity. The results showed greater tibiofemoral angle, femoral anteversion and hip internal rotation were significant predictors of greater Q angle (p< 0.05). Greater femoral anteversion, hip internal rotation and tibiofemoral angle results in greater Q angle, with changes in tibiofemoral angle having a substantially greater impact on the magnitude of the Q angle compared with femoral anteversion and hip internal rotation. Thus identifying the postural factors that influence Q angle, excessive stress and potential injury is of considerable importance. Clinically this has implications for both preseason screening and clinical treatment of subjects or patients."
