To investigate the degree of change in the craniovertebral angle (CVA) of the neck extension movement according to Nguyen Van Huong's exercises method on students with a forward-looking head position. Subjects and Method:Subjects and Method: Subjects and Method: Subjects and Method:Subjects and Method: Subjects and Method: Subjects and Method: Subjects and Method: Subjects and Method: Randomized controlled trial without a control group.

Position the phone 80 cm across the C7 vertebra away from the volunteer and to the left of their heart on a tripod to snap a picture. The picture is put into AutoCAD three times to determine the average CVA. Results: The 15-minute exercise group's post-exercise CVA angle increased by 9.74 degrees relative to before exercise (p < 0.05), proving statistical significance. The 7-minute exercise group's post-exercise CVA rose 7.79 degrees above its pre-exercise value. The CVA results after exercise in both groups increased significantly compared to before exercise (p < 0.05), which was statistically significant.
