Radiographic images obtained in the sagittal plane (cervical global angle) showing
patient progress. (a) At initial onset (5.3 ); (b) 5 years after initial onset (before
AM) (0.1 ); (c) 7 years after initial onset (2 years after AM) (5.1 ).

However, text neck was observed (Fig. 1a). However, cervical spine kyphosis was observed, and the cervical global angle) was calculated to be 0.1  (Fig. 1b). In addition, cervical spine kyphosis showed improvement (cervical global angle: 5.1 ) (Fig. 1c).
T2-weighted magnetic resonance imaging scans showing patient progress. (a) Image taken
in the sagittal plane 5 years after initial onset (before AM); (b) image taken in the
axial plane 5 years after initial onset (before AM) (CDH diameter at C4-5: 5.5 mm); (c)
image taken in the sagittal plane 7 years after initial onset (2 years after AM); (d)
image taken in the axial plane 7 years after initial onset (2 years after AM) (CDH
diameter at C4-5: 4.2 mm).

T2-weighted MRI revealed a left paracentral to intraforaminal lesion with disk herniation of protrusion type at C4-5 (Fig. 2a,b). T2-weighted MRI scans revealed loss of disk herniation of protrusion type at C4-5 (CDH diameter: 4.2 mm) (Fig. 2c,d).
Photographs of the towel used during AM. (a) The rolled towel (about the size of a
bath towel); (b) placement of the rolled towel under the back of the neck (lower
cervical spine level) and subsequent height adjustment (arch). The shoulder girdle and
occipital region should always be in contact with the ground.
