The aim of the study was to investigate the thickness of deep neck muscles during neck endurance tests using ultrasonography images to assess muscle sizes in persons with or without neck pain experience. Sixty-five university students volunteered for the study. The thicknesses of longus colli, longus capitis, semispinalis and cervical multifidus were assessed bilaterally using diagnostic ultrasound equipment during each endurance test. Participants were divided into two groups based on their Neck Pain(NP) experience; 45 subjects of those had no experience of NP (Group1) whereas 20 subjects of those reported NP experience sometime in their lives (Group2). Endurance time of both neck flexion and extension tests in Group1 showed significantly longer than Group's (p<0.01). The thicknesses of deep neck flexors and extensors were observed smallest at the terminal of endurance tests in general. Only left longus colli was found to be significantly smaller at rest in subjects of Group2 than Group 1's (P=0.02). The size difference between at contraction and the terminal of right longus capitis was observed bigger in subjects of group1 than subjects in group2. Future studies are needed to conduct with clinical subjects to assess contraction patterns of neck muscles.

목 디스크는 경추(목뼈) 사이의 디스크가 삐져나오거나, 뼈조직이 비정상적으로 자라 목으로 지나가는 척추신경을 압박하여 통증이 발생하는 질환이다. 목디스크는 뒷목 통증부터 저림, 감각 둔화 등의 증상이 서서히 나타나기 때문에 환자 스스로 질환을 자각하기가 쉽지 않아 적절한 치료시기를 놓치는 경우가 많다. 그러나 목디스크는 중증으로 발전할 경우 중추신경 마비로 인한 호흡곤란, 전신마비 등 치명적인 증상을 일으키기도 하므로 주의해야 한다.

This study investigated the effects of corrective exercise and TECAR on cervical alignment, pain threshold, and pain in forward head posture patients. The subject includes 30 forward head posture patients. In the intervention methods, the experimental group combined corrective exercise and TECAR treatment. Only the corrective exercise was applied to the control group. Assessments were made on cervico vertebra angle (CV angle), pain pressure threshold (PPT) and neck disability index (NDI) visual analog scale (VAS). The intervention was conducted six times a week for two weeks. Both groups showed significant differences in CV angle, PPT, NDI, and VAS. Also, PPT, NDI, and VAS excluding CV angle were significantly improved in the study group compared to the control group. These results suggest that the intervention method that combines corrective exercise and TECAR treatment has a more positive effect on pain and ADL ability of forward head posture patient.

척추의 가장 윗부분인 경추(목뼈)는 7개의 뼈로 이루어져 있으며, 위로는 머리, 아래로는 역시 척추의 일부인 흉추와 연결되어있다. 경추는 움직임이많고 큰 만큼 인체에서 아주 중요한 역할을 한다. 그러나 잘못된 자세와 오랜 시간 고정된 자세의 일과로 현대인들의 목은 뻐근하다. 더욱이 컴퓨터작업이 늘어나면서‘컴퓨터 모니터 증후근’, ‘거북목 증후군’등이 생겨날정도이다. 목 부위의 통증은 크게 척추 이상과 근육의 이상으로 인해생기는 경우가 대부분인데 이들의 초기증상은 매우 비슷해서 스스로 판단하기 어렵기 때문에 목 부위 통증이 간헐적으로 생기는 경우라면, 어떤 원인에 의해서인지 정확한 진단이 필요하다. 이번 호에서는 인체의 신비,‘목’에 대해 관절척추전문 세란병원 오명수 척추센터장과 자생한방병원목디스크센터 송우섭 원장의 도움말을 들어본다.

The purpose of this study was to evaluate the effects of using cervical spinal stabilization exercise for the improvement of pain intensity, cervical range of motion, neck disability index, reposition sense, muscle tenderness with chronic neck pain in private security. For 21 patients diagnosed with chronic cervical pain and divided into cervical spinal stabilization exercise group and postural correction exercise group. Each exercise was conducted for 8 weeks. Pain and neck disability index were measured before and after exercise using the visual analogue scale(VAS) and the neck disability index(NDI). Range of motion were measured electronic goniometer, muscle tenderness of upper trapezius ad sternocleidomatoid were measured algometer, reposition sense were measured reposition panel before and after exercise. After 8 weeks of exercise, the cervical stabilization exercise group pain and neck disability were significantly decreased(p<0.05). Also there was significant difference in both group(p<0.05). In addition, range of motion, muscle tenderness reduce rate, reposition sense were significantly increase as compared to the pre-post exercise in cervical stabilization exercise group(p<0.05). But there was no significantly difference in postural correction group before and after exercise(p>0.05). And there was significantly increase more cervical stabilization exercise group than postural correction exercise group in range of motion, muscle tenderness reduce, reposition sense. In summary, cervical spinal stabilization exercise is more effective in improving cervical range of motion, muscle pain, reposition sense in private security on chronic cervical pain patients, in reducing patients' pain and disability. It is an effective treatment to aid rehabilitation in these cases.

The purpose of this study was to work related musculoskeletal disorders are a major. Occupational disease of the dental care profession is no exception. The survey was self-reported questionars of 300 dental hygienists that 268 dental hygienists reply to self-reported survey. This study results are as follows: Subjects of research analyzing the degree of physical musculoskeletal disorders pain, shoulder 90.3%, neck 89.2%, leg 83.6%, 81.7% back, hand/wrist/fingers 75.7%, arm/elbow, according to 52.8%. Therefore the work province of the research object people the musculoskeletal disorders appeared different. Generally characteristic was taller dental hygienists lower back pain and were out of less weight, study subjects had neck and arm pain. 29~33 year-old age the shoulder, over the age of 34 the arm/elbow to be high (p<0.05). Working environment to become a career, the more hand/wrist/fingers and the pain increased (p<0.05). The neck, shoulders (p<0.05), arm (p<0.01), waist high in the 3~4 years experience. And leg/foot was in the 1~2 years experience. This increase in working hours had increased pain in the neck but the hand/wrist/finger pain in the small hours of experience in the high pain(p<0.01). Conclusion of the musculoskeletal disorders of the dental hygienists often than the average for this risk is recognized. When it occurs early in treatment can be simple, but time is left to revert to normal when you do not already. Therefore, maintaining proper posture and dental hygienists, pain or fatigue appeared to accumulate immediately treated continued efforts are needed.

The purpose of this study was to investigate the relationship between neck posture and range of motion and neck disability index(NDI) in young adults with reduced cervical lordosis. This study selected 34 young adults with cervical lordosis reduced (Cobb's angle less than 35 degrees). The assessor measured neck flexion, extension, left lateral flexion, right lateral flexion, left rotation, right rotation and forward displacements of all subjects using cervical of range motion instrument, Then, the NDI was evaluated. After all assessments, degree for cervical lordosis was divided into two groups: bottom group(severe cervical lordosis) and top group(mild cervical lordosis). The bottom group was significantly higher in Cobb's angle, extension, left lateral flexion, right lateral flexion, left rotation, right rotation and forward displacement compared to the top group (p<.05). There was no significant difference between the two groups in flexion, NDI(p >.05). In comparison of subscale of NDI, top group was significantly higher in pain, lifting, and headache than bottom group (p <.05). In correlation analysis, Cobb's angle showed significant positive correlation with flexion, extension, left lateral flexion, right lateral flexion, left rotation and right rotation(p<.05), and showed significant negative correlation with forward displacement, NDI(p<.05). Cobb's angle showed a significant negative correlation with pain, lifting, and headache of subscale of NDI(p<.05). The findings of this study potentially suggest that neck posture may affect the cervical range of motion and pain.

The purpose of this study was to determine the effect of extracorporeal shock wave therapy for the neck-shouler muscles of complex pain scales of the 20s adults with VDT Syndrome to prolonged smartphone use. Twenty subjects with neck pain due to VDT syndrome participated in the experiment. They were randomly divided into 10 experimental groups and 10 control groups. Experimental subjects were conducted for 4 weeks, 5 days a week. The experimental group was subjected to extracorporeal shock wave therapy 2000 times at an intensity of 5 Hz and 2.0 bar once, and the control group performed self-stretching exercise for 30 minutes once. Subjects measured and compared neck-shoulder pain with VAS and PPT before and after the experiment. Data analysis was performed with SPSS win 18.0, and correspondence comparison was performed to analyze the results of the experimental group and the control group before and after the experiment. After the experiment, the experimental group decreased more in VAS and PPT of the neck-shoulder muscle. but the control group was no difference. Though these results, extracorporeal shock wave therapy was showed a reduction in pain after treatment than before treatment but there are no difference in the pain reduction after self-stretching exercise. Thus, extracorporeal shock wave therapy is expected to be used as a variety of treatments to reduce neck-shoulder pain as a cause of VDT syndrome.
