From patients presenting to the clinic with TMJ disorders, it was found that most of them had a poor cervical posture with an anterior head tilt (e.g., Figure 1). And the correlation between incorrect cervical spine posture and TMJ has been reported in the literature. As seen in Figure 1, the head is tilted forward with the ear in front of the body. This posture causes the muscles to pull the mandible backward, potentially compressing the posterior tissue of the articular disc, causing arthritis with extrinsic pterygoid muscle spasm, and further potentially causing forward displacement of the articular disc, resulting in the clinical symptoms common to TMJ disorders, pain, restricted mouth opening, or popping in the preauricular region. In clinical treatment, it is also found that many patients often have good results through the correction of cervical posture, and it can help computer and cell phone people to relieve neck fatigue and reduce the development of cervical spondylosis. Figure 1 correct posture (see Figure 2): “chin collection”: standing position, tucked abdomen and chest, shoulders braced and slightly backward, hands torso gathered and naturally drooping, jaw slightly tightened, gaze level, back waist tightened, pelvis up, leg muscles slightly tense, the inner knee slightly clenched, so that the spine to maintain the normal physiological curve, from the side From the side: the ears, shoulders, hips, knees and ankles are kept in the same vertical line. This can be accomplished by standing against a wall. Figure 2
