Abstract

AIM: The aim of the study was to evaluate the effects that an anterior cruciate ligament (ACL) injury of the knee has on postural control and activity of neck, head and trunk muscles in order to investigate the existence of connections between the masticatory system and body posture. METHODS: Surface electromyographic (sEMG) activity of the muscles and their asymmetry index, at mandibular rest position, and during maximal voluntary clenching (MVC), and posturometric and stabilometric measurements of 25 patients (mean age 28+/-9 years) having undergone ACL injury of the left knee were compared with a control non-pathologic group. RESULTS: At rest, the patients showed a higher sEMG activity of the anterior temporalis, masseter, sternocleidomastoid and lower trapezius, compared with the control subjects (P
