Objective. To investigate effects of augmented feedback on knee valgus angles and hip muscle activity. Design. Repeated measures pre-test - post-test design to determine the effects of augmented feedback on knee kinematics and muscle activity. Setting. Research Laboratory. Subjects. 32 healthy, recreationally active females (age = 20.3+/-1.3 yrs, height = 166.5+/-7.4cm, mass = 66.6+/- 12.4 kg) displaying visual knee valgus. Intervention. Intervention subjects were given video and verbal feedback regarding their landing technique. Statistical analysis. Mixed model repeated measures ANOVA comparing control and intervention groups, and pre-test versus post-test; correlational analysis. Main outcome measure(s). Knee valgus angles; EMG amplitude of gluteus medius, gluteus maximus, hip adductors during a jump landing. Results. Significant differences in knee valgus angles were observed post intervention; however, muscle amplitude did decrease during the landing phase. Significance. Augmented feedback can alter kinematics and muscle activity however, more research is needed
Key words. Augmented feedback, knee valgus, muscle activity, jump landing
