Clinical features: The patient had morning headaches and cervical spine pain. Due to abnormal tooth wear, bruxism had been previously diagnosed and was verified by observation during sleep. She also had abnormal postural and palpatory findings, indicating upper cervical joint dysfunction. Intervention and outcome Bilateral rotary cervical stretching/mobilization and a vectored high-velocity, low-amplitude adjustment were performed in the upper cervical spine, using the atlas transverse process as the contact point. There was complete relief of the chronic subjective symptoms concomitant with remission of the objective signs of joint dysfunction.
CONCLUSIONS: Cervical, particularly upper cervical, spine muscle-joint dysfunction should be considered as a potential etiology in chronic childhood sleep bruxism.
