1 Electromyographic Activity of the Cervical Flexor Muscles in Patients With Temporomandibular Disorders While Performing the Craniocervical Flexion Test: A Cross- Sectional Study by Susan Armijo-Olivo, Rony Silvestre, Jorge Fuentes, Bruno R. da Costa, Inae C. Gadotti, Sharon Warren, Paul W. Major, Norman M.R. Thie, and David J. Magee ptjournal Volume 91(8):1184-1197 July 31, 2011 © 2011 American Physical Therapy Association

2 Descriptive Statistics of Height, Weight, and Age and Clinical Characteristics of Participants by Groupa. Susan Armijo-Olivo et al. PHYS THER 2011;91:1184-1197 © 2011 American Physical Therapy Association

3 Craniocervical flexion test. Susan Armijo-Olivo et al. PHYS THER 2011;91:1184-1197 © 2011 American Physical Therapy Association

4 Normalized electromyographic (EMG) activity of sternocleidomastoid (SCM) and anterior scalene (AS) muscles in participants with myogenous temporomandibular disorders (TMD), those with mixed TMD, and those who were healthy while performing the craniocervical flexion test.
