Primary Outcome Measures

Name	Time	Method
IMPROVEMENT OF CRANIOVERTEBRAL ANGLE IN AT LEAST 15%<br><br>The craniovertebral angle (CVA) is measured to be that between a horizontal line that crosses the body of the seventh cervical vertebra (C7) and the line from the tragus of the ear to the spinal apophysis of C7. Two lateral photographs are taken of the subject seated and standing still. For the first photograph, the subjects are asked to sit with their arms on their legs, and to rest their back and buttocks on the back of the chair, with both feet on the ground. The examiner instructs them to fix their gaze on an imaginary point on the wall directly in front. For the second photograph, the subjects stand still in a posture as natural as possible, with arms resting along the body, and directing their gaze as in the previous case.[AFTER INTERVENTION]

Secondary Outcome Measures

Name	Time	Method
INCREASE OF VERTICAL MOUTH OPENING(VMO) IN AT LEAST 10%<br><br>The maximum amplitude of VMO is measured using a digital gauge (Fino Digital Caliper, Model 59112, Germany) with a sensitivity of 0.01 mm. Measurements are made in two positions: (i) the subject supine with flexed hips and knees, and hands resting on the abdomen; and (ii) subject seated with back support and feet resting on the floor. The instruction given to the subject is simple: Open your mouth as much as possible without there being any sensation of pain or discomfort. The examiner then placed one end of the calliper on the middle incisor of the upper jaw incisor and the other on the central incisor of the jaw line. Three consecutive measurements were made, with a resting period of 30 seconds between each. The mean of the three measurements was taken as the value for the subsequent analyses. This procedure has proven to have high intra-examiner reliability (ICC=0.90-0.98)[AFTER INTERVENTIOn]
