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+/-2.9 years, height = 169.7+/-9.1 cm, weight = 68.4+/-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
