본 연구는 헤드 마운티드 디스플레이(Head-Mounted Display; HMD) 사용이 건강한 젊은 성인들의 목관절가동범위(CROM)와 목 근육 두께 및 통증에 미치는 영향을 분석하였다. HMD 군(남자 16명, 여자 7명)은 HMD를 착용하고 30분 동안 정해진 영상을 시청하도록 하였다. 대조군(남자 15명, 여자 8명)은 HMD군과 동일한 자세로 HMD 착용없이 30분 동안 앉아있게 하였다. 실험 전·후에 목관절가동범위, 위등세모근과 어깨올림근의 두께와 압력통증역치를 측정하고 대응표본 t검정과 독립 t검정으로 분석하였다. HMD 군의 목관절가동범위와 양쪽 위등세모근과 어깨올림근의 압력통증역치는 사전 검사 보다 유의하게 감소하였고(p<.05), 양쪽 위등세모근의 두께는 유의하게 증가하였고(p<.05). 반면에, 대조군은 목관절가동범위, 근육 두께 및 압력통증역치에서 유의한 차이가 없었다(p>.05). 분석 결과, 장시간 HMD 사용은 목관절가동범위와 압력통증역치를 감소시키고 근육을 비대하게 하여 목과 어깨의 근골격계 질환을 야기할 수 있으므로, 본 연구는 올바른 자세를 유지하며 적절한 시간 동안만 HMD를 사용할 것을 권장한다.

Background: This study examined the effects of the muscle energy technique and cervical traction after applying conservative physical therapy in patients with cervical radiculopathy. Methods: Patients were randomly divided into two groups muscle energy technique (8 subjects) and cervical traction (8 subjects). Each group performed their exercise 70 minutes per day, three times week for four weeks. Pain intensity was measured with a visual analogue scale (VAS). Function was measured with the neck disability index (NDI). Cervical range of motion (ROM) was measured with a cervical range of motion (CROM) goniometer. Results: After four weeks of therapy, VAS (p<.05) and NDI (p<.05) significantly decreased, and ROM significantly increased in both groups (p<.05). There were also significant differences between the two groups for these three measures (p<.05). Conclusion: The muscle energy technique and cervical traction are more effective than cervical traction alone in reducing VAS and NDI and increasing ROM in patients with cervical radiculopathy.

PURPOSE: This study examined the effects of the myofascial release and cervical traction after applying conservative physical therapy to patients chronic neck pain. METHODS: Patients were randomly divided into two groups, namely myofascial release (7 subjects) and cervical traction (7 subjects). Each group performed their therapy 45 minutes per day, two times a week, for four weeks. Pain intensity was measured using the visual analog scale (VAS). Function was measured with the neck disability index (NDI). The cervical range of motion (CROM) was measured with a cervical range of motion (CROM) goniometer. RESULTS: After four weeks of therapy, the VAS (p < .05) and NDI (p < .05) significantly decreased, and ROM significantly increased in both groups (p < .05). There were also significant differences between the two groups for these three measures, except for neck flexion and neck extension(p<.05). CONCLUSION: Myofascial release and cervical traction are more effective than cervical traction alone for reducing VAS and NDI and increasing ROM in patients with chronic neck pain.

Background: Neck pain is a major health problem in developed countries and has a lifetime prevalence of 50%. Major problems include a reduced cervical range of motion, muscle stiffness, dysfunction, postural changes, and decrease in psychosocial level. Objects: This study aimed to investigate the effects of applying the upper trapezius inhibition dynamic taping to patients with chronic neck pain on their neck pain, functional level, cervical range of motion, psychosocial level, and neck posture. Methods: The study design was a randomized controlled trial. A total of 40 patients with neck pain participated in this study and were randomly assigned to a Dynamic Taping group (n = 20) or Sham Taping group (n = 20). In both groups, basic intervention cervical pain control therapy and shoulder stabilization exercise program were performed. In addition, dynamic taping and sham taping were applied to participants in the Dynamic Taping and Sham Taping groups to inhibit the trapezius muscle, respectively. All interventions were performed three times a week and a total of 12 times for 4 weeks, and the participants' neck pain, functional impairment level, cervical range of motion, psychosocial level, and neck posture were measured and compared before and after the intervention. Results: Both groups showed significant differences in neck pain, functional level, cervical range of motion, psychosocial level, and neck postural before and after the intervention (p < 0.05). Moreover, there were significant differences between the two groups regarding the functional level and neck posture (p < 0.05). Conclusion: Inhibition dynamic taping of the upper trapezius muscle suppression is an effective method with clinical significance in reducing pain in individuals with chronic neck pain and improving the functional level, cervical range of motion, psychosocial level, and neck posture.

Purpose : The purpose of this study was to investigate the correlation between shoulder gradient, range of motion of the neck, and subjective pain level of the potential risk group of smart-phone addiction. Methods : The subjects of this study were 90 women's who had potential risk of smart-phone addiction. VAS was used to measure subjectively pain intensity. Global Postural System was used to measure forward head posture. CROM was used to measure flexion, extension, lateral flexion of cervical range of motion. Results : The results of this study showed that was significant positive correlation between the both shoulder gradient, and cervical range of motion(p<.05). Statistically significant negative correlation between the VAS and left lateral flexion(p<.05). Conclusions : The difference between the gradient of both shoulders increased with the use of smart-phone addiction, and the cervical left lateral flexion decreased as the pain increased. This suggests that recognition on decrease of using smart phone and postural correction is necessary.

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: This study examined the effects of the muscle energy technique and cervical traction after applying conservative physical therapy to patients with cervical radiculopathy. Methods: Twenty-six patients with cervical radiculopathy were randomized into two groups: the experimental group (n=13) and the control group (n=13). The two groups performed the muscle energy technique and for 4 weeks, 3 times a week, in 70-minute sessions. Pain, range of motion, function, and muscle performance were assessed using the visual analogue scale (VAS), cervical range of motion (CROM) goniometer, neck disability index (NDI), and stabilizer pressure biofeedback, before and after training. Results: After four weeks of therapy, the VAS (p<.001), NDI (p<.01), and the maximum strength of the deep neck flexion muscles significantly decreased (p<.01) and CROM significantly increased in both groups (p<.05). Conclusion: The muscle energy technique and therapeutic modalities such as cervical traction are effective in reducing VAS and NDI and increasing CROM and muscle performance in patients with cervical radiculopathy.

Purpose: The aim of this study was to apply suboccipital muscle inhibition combined with neck muscle stabilization exercise to 20~30s IT industry employees who suffer from chronic non-specific neck pain. Methods: This study was designed as single-blind and randomized controlled trial. The study participants were 20~30s IT industry employees with chonic non-specific neck pain (VAS 3/10) who were divided into an experimental group (n= 20) subjected to suboccipital muscle inhibition with neck muscle stabilization exercise, and control group (n= 20); suboccipital muscle inhibition only. The intervention was applied three times per week for eight weeks. The neck pain·pressure pain threshold·range of motion, and disability index were measured at the 1st, 8th, and 10th week at follow up, then analyzed with an analysis of variance(ANOVA) using the SPSS program. Results: The total number of study participants was 37 (experimental group 19, mean age 34.6±5.3, control group 18, mean age 35.7±4.9). The comparison and analysis of change in VAS, the pressure pain threshold, and the range of motion except the extension (p>.05) revealed a statistically significant decrease between groups over eight weeks and follow up measurement (p<.01). Regarding the within the group differences, the right side of the neck pressure pain threshold showed a statistically significant decrease over eight weeks in the control group (p<.01). The right and left lateral flexion, and the right and left rotation were statistically significant for the experimental group over eight weeks and follow up measurement, but only the left lateral flexion (p<.05) for the control group over eight weeks. The neck disability index showed a slight decrease but this was not satistically significant for the between-grop or the within-group differences (p>.05). Conclusion: The intervention of suboccipital muscle inhibition and a neck muscle stabilization exercise are more beneficial for neck pain and the range of motion than the application of suboccipital muscle inhibition alone.

PURPOSE: This study aims to compare the effects of upper backbone joint mobilization and self-stretching exercise in the patients with chronic neck pain. METHODS: Thirty seven patients with chronic neck pain were divides into self stretching group(SSG, n=18) and mobilization group(MG, n=19). To assess the degree of neck pain, the visual analog scale (VAS) was utilized, and to measure the joint range of motion at the flexion-extension, it was compared and analyzed by using the cervical range of motion (CROM) device. RESULTS: The joint range of motion and visual analog scale of SSG and MG showed significant effects on both groups. In the comparison of groups, there was no significant difference, but it indicated effects on improving the pain and the range of joint motion in MG. CONCLUSION: According to the analysis, not only self-stretching exercise intervening for direct treatment but also upper backbone joint mobilization intervening for indirect treatment are effective to improve the pain and the range of motion.

Purpose: This study was conducted to investigate changes in the cervical and lumbar flexion-relaxation ratio, range of motion, pressure pain threshold, and perceived comfort following the wearing of a trunk brace during smartphone watching. Methods: To calculate the number of subjects for this study, an analysis with G^*Power was performed at a statistical power of 0.8, an effect size of 0.5, and a significance level of 0.05, based on the results of a preliminary experiment on five subjects. In total, 27 adult men and women were recruited who had been informed of the study's purpose and process and had agreed to participate. All subjects watched content on a smartphone for 20 minutes in the same posture and conditions while wearing and not wearing a trunk brace, and then their cervical and lumbar flexion-relaxation ratio, range of motion, pressure pain threshold, and perceived comfort were measured. Results: Compared to the non-wearing of a trunk brace, the wearing of a trunk brace resulted in a statistically significant smaller decline in cervical extension and right-side cervical rotation (p<0.05). When the subjects wore a trunk brace, their right- and left-side cervical and right-side lumbar pressure pain statistically significantly improved when compared to not wearing a trunk brace (p<0.05). They also perceived a significantly lowered level of comfort 20 minutes after wearing a trunk brace compared to immediately after wearing it (p<0.05). Conclusion: The trunk brace was effective in reducing declines in right-side cervical rotation and the occurrence of left- and right-side cervical and right-side lumbar pressure pain. The findings indicate the need to improve the perceived comfort of trunk braces.
