Purpose : The purpose of this study was to compare the effect of exercise on the neck muscles activities between scapular stability and McKenzie stretch exercise in the forward head posture subjects. Method : After measuring cervical alignment using the Global Posture System, 20 volunteers with forward head posture posture were selected and divided into two groups. The experimental group A(n=15) and Experimental group B(n=15) participated in respectively and McKenzie neck stretching exercise, three times per week for 4 weeks. The scapular stabilization exercise program was comprised middle and lower trapezius strength exercises and the stretching exercise program was comprised levator scapulae and upper trapezius stretching exercise. The activities of the muscles of the posterior neck was then measured using electromyography. Result : After the intervention, there was significant difference of a electromyography activity changes between the pre-test and post-test in the experimental group. Conclusion : This study showed that both scapular stabilization and McKenzie neck stretching exercises are more effective for reducing neck muscles activities.

Objective: Flexed posture commonly increases with age in older adults and is characterized by kyphosis and forward head posture. Changes in the posture with age affect both balance and mobility. This study was conducted to examine the effects of a cervical stabilization exercise for community-dwelling older adults to improve balance. Design: Two groups pretest-posttest design. Methods: Fifty older adults were randomly assigned into the cervical stabilization exercise group (n=24) and control group (n=25). The cervical stabilization exercise group (n=24) participated in group exercise for 60 minutes twice a week over 4 weeks. Timed up and go test (TUG), four square step test (FSST), functional reach test (FRT), postural sway, cervical range of motion (CROM), proprioception, craniovertebral angle (CVA) were evaluated before and after the intervention. Results: TUG, FSST, FRT, CROM, Proprioception, CVA showed significantly greater improvement, compared with a control group (p<0.05). Conclusions: Findings of this study demonstrate that cervical stabilization exercise can help improve not only neck functional capacities but also balance. Therefore, it may be used as an effective balance exercise program for community-dwelling older adults.

본 연구의 목적은 거북목을 가진 사람에게 메켄지 폄운동과 어깨안정화운동이 앞쪽머리자세에 미치는 영향에 대해 알아보는 것이다. 연구대상자는 30명의 거북목을 가진 평범하고 건강한 사람들로 이루어져 있다. 대상자는 어깨안정화운동과 메켄지 폄운동으로 나누어(인원=30, 남자 15명, 여자 15명) 무작위로 나누어 6주 동안 실시되었다. 본 연구는 마름근, 아래등세모근의 운동프로그램과 깊은목굽힘근, 위등세모근, 어깨올림근의 신장프로그램을 통한 목뼈의 머리척추각(Cervical Vertebra Angle) 값과 각 근육별 근전도의 차이를 알아보았다. 앞쪽머리자세와 경우에는 목과 등근육의 활성도가 감소하고 피로도는 증가함을 보였다. 이러한 결과는 목과 머리의 불안정한 상태를 안정시키기 위해서는 위등세모근, 깊은목굽힘근, 어깨올림근의 신장과 마름근, 아래등세모근의 운동을 통해 거북목의 개선에 긍정적인 변화를 줄 것으로 보인다. 이러한 근육들의 불균형한 수축과 과도한 긴장으로 근육의 경직과 피로가 누적되며 이러한 상태가 계속 유지되게 되면 만성화상태가 되어 근육의 불균형으로 인해 통증을 유발할 수 있으며, 피로의 누적으로 인하여 자극에 대한 반응과 근력을 약화시켜서 목 디스크가 발생할 확률이 높아질 것으로 사료된다.

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: The aim of this study was to investigate the effect of mandible position on proprioception and range of motion (ROM) during neck stabilization exercise using a sling in healthy adults. Methods: The subjects were randomly assigned to either a sling exercise and mandible open group (n=10) or a sling exercise and mandible closed group (n=12). The sling exercise-mandible open group and sling exercise-mandible closed group took part in an exercise program for 30min, three times per week for 4 weeks. After each training session, head repositioning accuracy (HRA) and the ROM of the cervical spine were measured. Wilcoxon's test was conducted to verify changes within each group, and the Mann-Whitney U test was performed to examine between-group differences. Results: The HRA of the cervical spine was significantly increased during left rotation and extension in the sling exercise-mandible open group. In addition, there were significant differences in both rotations and extension in the two groups. The ROM of the cervical spine increased significantly during both rotations in the sling exercise-mandible closed group. In addition, there was a significant difference in right rotation and extension in both groups. Conclusion: Cervical stabilization exercise using a sling, with the mandible closed increased proprioception and the ROM of the cervical spine.

Background: Neck pain is a common problem in the general population and second only to low back pain in musculoskeletal problems. The aim of this study is to compare three different types of exercise training in patients with chronic neck pain. Methods: This study was conducted on 45 patients with neck pain. Patients were divided into 3 groups: Group 1 (conventional treatment), Group 2 (conventional treatment plus deep cervical flexor training), and Group 3 (conventional treatment plus stabilization of the neck and core region). The exercise programs were applied for four weeks, three days a week. The demographic data, pain intensity (verbal numeric pain scale), posture (Reedco's posture scale), cervical range of motion ([ROM] goniometer), and disability (Neck Disability Index [NDI]) were evaluated. Results: In all groups, a significant improvement was found in terms of pain, posture, ROM, and NDI values in all groups (P < 0.001). Between the groups, analyses showed that the pain and posture improved more in Group 3, while the ROM and NDI improved more in Group 2. Conclusions: In addition to conventional treatment, applying core stabilization exercises or deep cervical flexor muscle training to patients with neck pain may be more effective in reducing pain and disability and increasing ROM than conventional treatment alone.

This study aimed to determine the usefulness of classifying patients with neck pain on the basis of the results of passive scapular elevation test. We classified 21 patients with neck pain into positive (n=12) and negative (n=9) groups on the basis of passive scapular elevation test; the 2 groups then equally performed scapular stabilization exercise program for 30 min, 3 times a week, for 4 weeks. Visual analogue scale (VAS), neck disability index (NDI), and range of motion (ROM) were recorded both before and after the intervention for both groups. Paired t-test was used to determine that there were significant changes between before and after the intervention, and independent t-test was used for analyzing changes between two groups of dependent variables. After 4 weeks of training, we observed significant decrease in pain and disability (p<.05) and a significant increase in rotation, flexion, extension, and side-bending ROM (p<.05) in both groups. Further, between pre- and post-intervention evaluations, we observed a significant decrease in pain and disability and a significant increase in rotation and flexion ROM in the positive group than in the negative group (p<.05). These results indicate that passive scapular elevation test may be used to identify mechanical disorders of the cervicoscapular muscle in patients with neck pain. Therefore, we recommend the use of passive scapular elevation test to determine appropriate treatment intervention when treating patients with neck pain.

Purpose: This study examined the effects of neck stabilization exercises with vibratory stimulation on the neck disability index and thickness of the deep neck flexor. Methods: Thirty subjects (control group=15, experimental group=15) with mild neck pain were enrolled in the study. The control group underwent craniocervical flexion exercise (control group, CG) and the experimental group was given craniocervical flexion exercise with vibratory stimulus (experimental group, EG) (3 sets, 3 times per week for 6 weeks). To examine the effects of exercise, the subjects were evaluated using the neck disability index (NDI), the thickness of the deep neck flexor muscle, and muscle strength. An independent and paired t-test were used to compare the effects of the exercise between the groups. Results: The NDI score of the two groups increased significantly after 6 weeks of treatment (p<0.001) and there was a significant difference between the EG group at 3 weeks (p<0.05) and 6 weeks (p<0.01). The thickness of the deep neck flexor in the CG group increased significantly after 6 weeks of treatment in all pressure stages (p<0.001). The EG group showed a significant increase after 3 and 6 weeks of treatment in all pressure stage (p<0.001), and 22 mmHg, a significant difference between 3 and 6 weeks (p<0.05) and among 24, 28, and 30 mmHg at 6 weeks (p<0.05). The maximum muscle strength of the deep neck flexion muscles increased significantly in the two groups after 6 weeks of treatment (p<0.001) and there was significant difference between the EG group at 6 weeks (p<0.01). Conclusion: Craniocervical flexion exercise with vibratory stimulus decreases the NDI, and increases the thickness of the deep neck flexor and maximum muscle strength of the deep neck flexion muscles in patients with mild neck pain.

The development of a low-pollution burner is important for saving energy and preserving the environment. A low-pollution burner can be produced by lean-mixture combustion and general combustion technology. The flammable limit of premixed flame is narrower than that of diffusion flame. Producing a lean mixture of fuel results in an effective combustion condition, which in turn produces high load and low pollution. In this study, it was found that the influx of $Q_2$ had an effect on extending the lean flammable limits and flame stabilization in a doubled jet burner. And the flame, consisting of small eddies, can be stabilized by the nozzle neck phenomena.
