This study examined the effects of stretching and sling stabilizing exercises on changes in the angle of the cervical spine in military neck patients. The subjects were 20 adults diagnosed with a military neck(male:10, female:10) and they were randomly and equally assigned to a stretching exercise group and a sling stabilization exercise group. The total study period was four weeks. The intervention was applied three times per week for 60 minutes per each time. Before conducting the exercise, X-ray of each group was photographed to measure craniospinal angle(CVA) and cranial rotation angle(CRA). According to the result of comparing the two groups in changes in the cervical spine angle, there was no significant difference, and the result of comparing pre- and post-intervention was that there was significant change in CVA and CRA in the stretching group (p<.05) but there was no significant change in CVA and CRA in the sling stabilization exercise. Such result suggests stretching exercise is good for improving a military neck and stretching is more effective than sling in the therapeutic intervention for a military neck.

Purpose: This study was to identify the effect of cervical stabilization exercise with visual feedback on the craniovertebral angle and foot pressure in subjects with forward head posture. Methods: Thirty healthy adults were recruited in the study. Participants were randomly assigned to the stabilization exercise with visual feedback (SE-VF) group (n=15) or stabilization exercise (SE) group (n=15). The SE-VF group performed cervical stabilization exercise while sitting on a chair without a backrest and checking their side profile in real time a monitor 3m away. The SE group performed the same cervical stabilization exercise as the SE-VF group accompanied by without visual feedback. Craniovertebral angle (CVA) was measured to quantify forward head posture, and the foot pressure of the subjects were evaluated. Results: The foot pressure showed statistically significant differences pre and post in both midfoot and left metatarsal only in SE-VF group (p<0.05). Conclusion: These findings of this study showed that the cervical stabilization exercise with visual feedback was effective for the foot pressure of subjects. In addition, based on the results of this study, it is suggested that visual feedback will be effective in cervical stabilization exercise.

Objective : Laminoplasty is an effective surgical method for treating cervical degenerative disease. However, postoperative complications such as kyphosis, restriction of neck motion, and instability are often reported. Despite sufficient preoperative lordosis, this procedure often aggravates the lordotic curve of the cervical spine and straightens cervical alignment. Hence, it is important to examine preoperative risk factors associated with postoperative kyphotic alignment changes. Our study aimed to investigate preoperative radiologic parameters associated with kyphotic deformity post laminoplasty. Methods : We retrospectively reviewed the medical records of 49 patients who underwent open door laminoplasty for cervical spondylotic myelopathy (CSM) or ossification of the posterior longitudinal ligament (OPLL) at Pusan National University Yangsan Hospital between January 2011 and December 2015. Inclusion criteria were as follows : 1) preoperative diagnosis of OPLL or CSM, 2) no previous history of cervical spinal surgery, cervical trauma, tumor, or infection, 3) minimum of one-year follow-up post laminoplasty with proper radiologic examinations performed in outpatient clinics, and 4) cases showing C7 and T1 vertebral body in the preoperative cervical sagittal plane. The radiologic parameters examined included C2-C7 Cobb angles, T1 slope, C2-C7 sagittal vertical axis (SVA), range of motion (ROM) from C2-C7, segmental instability, and T2 signal change observed on magnetic resonance imaging (MRI). Clinical factors examined included preoperative modified Japanese Orthopedic Association scores, disease classification, duration of symptoms, and the range of operation levels. Results : Mean preoperative sagittal alignment was $13.01^{\circ}$ lordotic; $6.94^{\circ}$ lordotic postoperatively. Percentage of postoperative kyphosis was 80%. Patients were subdivided into two groups according to postoperative Cobb angle change; a control group (n=22) and kyphotic group (n=27). The kyphotic group consisted of patients with more than $5^{\circ}$ kyphotic angle change postoperatively. There were no differences in age, sex, C2-C7 Cobb angle, T1 slope, C2-C7 SVA, ROM from C2-C7, segmental instability, or T2 signal change. Multiple regression analysis revealed T1 slope had a strong relationship with postoperative cervical kyphosis. Likewise, correlation analysis revealed there was a statistical significance between T1 slope and postoperative Cobb angle change (p=0.035), and that there was a statistically significant relationship between T1 slope and C2-C7 SVA (p=0.001). Patients with higher preoperative T1 slope demonstrated loss of lordotic curvature postoperatively. Conclusion : Laminoplasty has a high probability of aggravating sagittal balance of the cervical spine. T1 slope is a good predictor of postoperative kyphotic changes of the cervical spine. Similarly, T1 slope is strongly correlated with C2-C7 SVA.

Background: The purpose of this study was to identify the effects of morphological Change of cervical spine to apply to neck retraction and extension regarding the straight deformity of cervical spine. Methods: A 40-year male subject with straight deformity of cervical spine participated in this study. The study subject underwent a cervical lateral radiography on the static position, neck retraction and neck extension on standing. Measurement method were using computer-based digital radiogram on a picture achieving computer system forthe centroid method, Cobb's angle and Jackson's angle. Results: Neck retraction was increased kyphosis on the C2-4 with lordosis on the C5-7. Neck extension was increased lordosis on the C2-7. Conclusions: These findings suggest that neck retraction was increased kyphosis and neck extension was increased lordosis based on the straight deformity of cervical spine. Therefore, we should be consider that neck extension exercise when increased lordosis for the patients of straight deformity of cervical spine.

Purpose: To measure the head tilting angle creating initial condylar cut-off and to find the head position inducing the superimposition of the cervical vertebrae over the mandibular ramus on panoramic radiograph. Materials and Methods: The panoramic radiographs were taken with Didactic skull on cervical spine model (Scientific GmbH, Hamburg, Germany) using Kodak 8000c Digital Panoramic radiography. For the inherent radiolucency of the plastic skull model, radiopaque 1 mm diameter lead wires were attached along the margin of the mandibular condyle, ramus, mandibular body, cervical vertebrae, and FH plane of the skull model. For measuring the head tilting angle creating the condylar head cutoff, panoramic radiographs were taken by tilting the FH plane downward in 5 degree increments. For finding the distance between transverse process of the third cervical vertebra and gonion inducing superimposition of cervical vertebrae on the mandibular ramus, panoramic radiographs were taken by decreasing the distance in 0.5 cm increments. Result and Conclusion: The condylar cutoff began to appear when the head of skull model was tilted downward by 15o. As the head tilting angle increasing, the condylar cutoff became more prominent. The superimposition of cervical vertebrae over the mandibular ramus began to appear when the distance between the gonion and third cervical vertebra was 1.0 cm. As the distance decreasing, the superimpostion became more prominent.

In the healthcare system, the human neck(cervical spine) is one of the most important organs. The area that supports the human head is the cervical spine. Nowadays, we are often overworked our neck to calls with the smart phone or see the monitors. In this paper, we investigate the abnormalities of lateral flexion and rotation of the cervical spine. The normal angle of lateral flexion is $20^{\circ}$ to $45^{\circ}$ and the normal angle of rotation is $50^{\circ}$ to $90^{\circ}$. If this angle is below normal and we feel pain, there is something wrong with the cervical spine. In addition, learn how to measure the lateral flexion and rotation of the neck or cervical spine, and also to find out how to treat an abnormality. We also look at how to prevent more than lateral flexion and rotation of the cervical spine. The experiment was carried out with 100 people in their 50s, men and women, to find out whether the neck is abnormal.

The purpose of this study was to the effects of a cervical stabilization exercise using pressure biofeedback intervention on suboccipital muscle tone, deep neck flexor muscle endurance, and craniovertebral angle in college students with forward head posture. The subjects of the study were selected as BCSEG(n=12) and CG(n=12), and the intervention was performed for 50 minutes, 3 times a week for 8 weeks. The results of the study showed that after biofeedback neck stabilization exercises, the suboccipital muscle significantly decreased in stiffness and muscle tone in the BCSEG(p<.01), and the deep neck flexors significantly increased in muscle endurance(p<.01) and craniovertebral angle(p<.01). The results of the cervical stabilization exercises with biofeedback are thought to improve cranio- vertebral angle by improving muscle function of the suboccipital muscles and deep neck flexors, which cervical stabilization exercises with biofeedback may be suggested as an intervention to improve FHP.

Objectives: The purpose of this study was to determine whether the cranial vertebral angle (CVA) and the range of motion (ROM) was different between participants with a forward head posture (FHP), with or without pain. Methods: Forty-four participants who had FHP participated in this study. The FHP was assessed digitally by measuring a lateral view the CVA for each subject. A cervical ROM device measured the cervical ROM. The volunteers were allocated to either, with pain (n = 22), or without pain (n = 22) groups, and pain was evaluated using the Numeric Pain Rating Scale. Results: The FHP in the pain group showed a significant difference in the CVA, and the cervical ROM in both flexion and extension, compared with those in the FHP without pain group (p < 0.05). Logistic regression analysis indicated that the occurrence of cervical area pain was higher amongst subjects who had a decreased CVA and flexion motion. Conclusion: This study suggested that decreased CVA and cervical flexion range, were predictive factors for the occurrence of pain in the cervical region.
