In this study, the effects of mobilization on quadriceps muscle strength and proprioception of knee joint are evaluated. The subjects are 35 girl students in the age range of 18-35. Quadriceps muscle strength in the dominant leg is measured by a dynamometer. Proprioception is measured in the same leg. Knee proprioception will be assessed by a 3D motion analysis system with 6 cameras (gait analysis system qualysis, Sweden). Grade 4 mobilization technique in an antroposterior direction for 3 minutes is used on the knee joint which is in 90 degrees of flexion. Immediately after mobilization the maximum isometric contraction is measured. Then proprioception will be re-evaluated. 20 and 30 minutes after the intervention, quadriceps muscle strength will be measured in the same way as before intervention.
