Scholarcy highlights

  • Synchronized electromyography and videofluorography were used to investigate the influence of altered head posture on hyo-mandibular movements, suprahyoid muscle length, suprahyoid working angle, and timing of suprahyoid and masseter muscle activity
  • Twelve adult male subjects with normal dentofacial morphology were investigated during the open-close-clench cycle
  • Using upright head position as reference, several statistically significant observations were made during forward flexion and backward extension of the head
  • The results indicate that head posture is a significant factor in studies of mandibular and hyoid bone movements, and masseter and suprahyoid muscle function
