The investigation of the myoelectric potential in individuals with a chewing side preference gives the muscular response patterns while resting and during activities [9,10].
The cross-effect between musculatures having symmetry of muscular electrical activation and chewing side preference, in other words, of the right chewing preference with the greater myoelectric potential of the left sternocleidomastoid and right anterior tibial; left chewing preference with greater myoelectric potential of the right sternocleidomastoid and left anterior tibial, possibly existed due to the possibility of muscle compensation for trying to reestablish the postural muscle balance.
