Objective:To investigate the effect of posture training on head posture in myogenic temporomandibular disor-ders(TMD)patients with forward head posture. Method:Forty-five myogenic TMD patients(6 male,39 female;age 29.24±6.13y)were recruited from the outpatient rehabilitation clinics of the Ninth People's Hospital of Shanghai Jiaotong University School of Medi-cine from January 2019 to February 2021.Under the design of a prospective controlled study,all patients were randomly divided into the posture training group(23 cases)and the control group(22 cases).The pos-ture training group received posture training for 3 weeks with 30 minutes each time;the control group only re-ceived health education.The patients in two groups received outpatient follow-up after 3 weeks.The maximum mouth opening(MMO)and pain intensity were measured before and after treatment,and the head rotation and craniovertebral angle were measured using the sagittal photograph. Result:The craniovertebral angle of the posture training group(n=22)after treatment were signifiicantly higher than the control group(n=20)(55.3°±2.3° vs 48.4°±4.4°,P＜0.001).The pain score in the posture training group was significantly lower than that in the control group(1.9±0.7 vs 2.9±0.8,P＜0.001).There were no sig-nificant group differences between the improvement of head rotation angle and MMO(P=0.437,P=0.313). Conclusion:Posture training can improve the head posture of myogenic and symptoms in TMD patients.
