Crosstalk between adjacent or antagonistic muscles of the human thigh has been measured accurately in order to clarify the use of surface electromyography (EMG) for identifying cocontraction of muscles during movement. The myoelectric crosstalk between the rectus femoris, vastus lateralis, vastus medialis, and the lateral and medial hamstring muscles of the thigh have been quantitatively identified. Crosstalk measurement relies on the ability to discriminate between a signal originating from the muscle fibers below the detecting electrode and a volume conducted signal from another muscle. Such discrimination has been obtained using electrical stimulation and a double-differential recording technique previously applied successfully for measuring crosstalk in the lower leg.

Abstract
Crosstalk between adjacent or antagonistic muscles of the human thigh has been measured accurately in order to clarify the use of surface electromyography (EMG) for identifying cocontraction of muscles during movement. The myoelectric crosstalk between the rectus femoris, vastus lateralis, vastus medialis, and the lateral and medial hamstring muscles of the thigh have been quantitatively identified. Crosstalk measurement relies on the ability to discriminate between a signal originating from the muscle fibers below the detecting electrode and a volume conducted signal from another muscle. Such discrimination has been obtained using electrical stimulation and a double-differential recording technique previously applied successfully for measuring crosstalk in the lower leg.
