  • Objective: To determine the relationship between clinical measures of core stability and trunk and knee kinematics and kinetics. Design: Results of the four core stability tests compared to data obtained performing a single leg squat. Subjects: 31 recreationally active individuals (9 males and 22 females, age = 22.1 plus/minus 2.9 years, height = 169.7 plus/minus 9.1 cm, weight = 68.4 plus/minus 10.5 kg). Statistical Analysis: Pearson r and Spearman's rho correlational analyses; independent samples t-tests. Main Outcome Measure(s): Knee valgus displacement, peak knee valgus angle, lateral trunk flexion displacement, peak lateral trunk flexion angle, trunk flexion displacement, peak trunk flexion angle, peak normalized knee valgus angle. Results: A significant positive relationship between core stability and trunk flexion displacement was observed. Significance: Additional research needs to be done in order to propose a direct relationship between core stability and non-contact knee injury prevention. Key Words: Core stability, knee valgus, trunk flexion, single leg squat.
