The purpose of this study is to clarify the lateralization of the knee function in normal subjects. Eleven healthy subjects (mean age is 29.3 years ; range is 20-40years) were studied. All subjects have no notable history about knee joint injury. Laterarity of the knee function was measured by muscle torque and electromyographic (EMG) properties. Each subjects was made to sit with his hip and knee joints at 90 degrees flexion position, and was direced to keep on extending his leg in maximal isometric contraction for five minuts. Surface electrodes were placed on the center of each muscle of rectus femoris (RF), vastus mediaris (VM) and vastus lateralis (VL). EMG properties and torque during maximal isometric contraction were measured using EMG amplifier and torque dynamometer. Integrated EMG and frequency components during maximal isometric contraction were analyzed to evaluate the laterality of EMG properties. Significant lateralization was not found in torque and EMG properties in this study. It is useful for assessing patients with knee injury, to compare the muscle torque and EMG property between affected side and sound side.
