Title: Electromyographic evaluation of a patient treated with extraoral traction: a case report
Abstract: Background This work seeks to provide information on the utility of surface electromyography (SEMG) as an aid for diagnosing orthodontic conditions. Classic orthodontic monitoring by radiography, plaster models, cephalometry, and photography can be improved by using SEMG before and during treatment, to prevent clinical worsening and relapses.
Case report This paper presents the SEMG results for a 10-year-old female patient, orthodontically treated by extraoral traction (EOT). Significant muscular variations in the patientís EMG were observed as she changed different postures and as headgear device was used.
Conclusion SEMG should be performed prior to the orthodontic treatment to assess the neuromuscular patientís pattern, in order to prevent strain induced by extraoral forces. EMG can be a valid aid for evaluating the patientís neuromuscular condition before, during, and after orthodontic treatment.
