Parameters of induced electrical activity of the right and left quadriceps femoris in healthy subjects were identical. But we have shown that in patients with coxarthrosis and gonarthrosis, the nociceptive influence from the affected joint asymmetrically inhibits the muscle activity of the right and left leg and their spinal centers. This effect is the strongest on the muscles located on the side of the damaged joint, but also influences the motor system of the symmetrical limb.

Key words: coxarthrosis, gonarthrosis, quadriceps femoris, nociceptive impulses, asymmetry of the electrical activity, H-reflex and M responses.
