This study tested the hypothesis that muscle related temporomandibular disorder patients with cervical muscle pain exhibit greater degree of psychological distress compared with patients without cervical muscle pain and controls. Thirty-eight muscle related temporomandibular disorder patients including 10 patients with cervical muscle pain and 41 healthy individuals as controls participated in the study. State and trait anxiety levels were assessed with the Spielberger's state and trait anxiety inventory. ⋯ They also demonstrated higher pain intensities in masseter and temporalis muscles compared with patients without cervical muscle pain. It has been suggested that either subjects with psychological distress are prone to temporomandibular disorders, or psychological distress is a manifestation of existing chronic pain conditions. The present findings demand further investigations and broader approach in management, as muscle related temporomandibular disorder patients with cervical muscle pain were both physically and psychologically compromised to a greater degree compared with patients without cervical muscle pain.
