Objective: Several muscles surrounding neck are vital not only for neck motion, but for upper extremities motions as well. Neck pain would affect neck and shoulder disability. The Neck Disability Index (NDI), Shoulder Pain and Disability Index (SPADI), and Visual Analogue Scale (VAS) are increasingly used to evaluate treatment effectiveness after chronic neck pain. The purpose of this study was to analyze the correlation of neck pain, shoulder pain, and quality of life in patients with chronic neck pain. Design: Cross-sectional study. Methods: Forty-three patients with neck pain participated in this study. Participants were instructed to place a mark on each item of three clinical measures that best represented their experience of his/her neck and shoulder problem over the last week. The outcome measures of the study were NDI, SPADI, and VAS for neck and shoulder pain and disability. Results: The NDI was significantly correlated with the VAS-Neck, SPADI-Pain, SPADI-Disability, SPADI-Total, and VAS-Shoulder (p<0.05). The VAS-Neck was significantly correlated with the VAS-Neck, SPADI-Pain, SPADI-Disability, SPADI-Total, and VAS-Shoulder (p<0.05). The SPADI-Total was significantly correlated with the NDI, VAS-Neck, SPADI-Pain, SPADI-Disability, and VAS-Shoulder (p<0.05). The SPADI-Pain was significantly correlated with the NDI, VAS-Neck, SPADI-Disability, SPADI-Total, and VAS-Shoulder (p<0.05). The SPADI-Disability was significantly correlated with the NDI, VAS-Neck, SPADI-Total, SPADI-Pain, and VAS-Shoulder (p<0.05). The VAS-Shoulder was significantly correlated with the NDI, VAS-Neck, SPADI-Pain, SPADI-Disability, and SPADI-Total (p<0.05). Conclusions: Neck disability in patients with chronic neck pain should be considered with disability and pain of the shoulder.

Background: The prevalence of neck pain and neck dysfunction is high in general population. However, there is little literature on the relationship and factors affecting neck pain and neck dysfunction. Objective: To investigate the correlation between neck and shoulder pain, headaches, neck and shoulder dysfunction, and sleep quality in adults with chronic neck pain, and factors affecting neck pain and neck dysfunction. Design: Cross-sectional study Methods : The sample included 114 subjects, who had complained of chronic neck pain for more 12 weeks. We conducted a Pearson's correlation between neck and shoulder pain, headaches, neck and shoulder dysfunction and sleep quality and a regression analysis of the related variables, thereby analyzing factors affecting neck pain and neck dysfunction. Results : In the present study, in adults with chronic neck pain, neck pain was positively correlated with the Neck Disability Index (NDI), Shoulder Pain and Disability Index (SPADI)-Pain score, and SPADI-Total score (p<.05). The NDI was positively correlated with neck pain, SPADI-Pain score, and SPADI-Total score, as well as with Pittsburgh Sleep Qulity Index(PSQI-K) (p<.05). Among the factors affecting neck pain, shoulder disability as assessed by the SPADI was a significantly associated with neck pain, while shoulder pain and shoulder disability determined by the SPADI were identified as significant variables among the factors affecting neck disability. Conclusion : These results indicated that as neck pain worsened, shoulder pain and neck and shoulder dysfunction also increased, which suggested that shoulder disability affected neck pain. In addition, as the neck dysfunction increased, neck pain and shoulder pain and shoulder dysfunction increased, and sleep quality deteriorated, which suggested that shoulder pain and shoulder disability affected neck disability.

PURPOSE: To investigate the correlation between sleep quality, neck and shoulder pain, neck and shoulder disability, headache, and smartphone addiction in adults, as well as factors affecting sleep disorders in adults. METHODS: A total of 112 adults in their 20s were recruited for participation in this study. This study measured Pearson's correlation of sleep quality, neck and shoulder pain, neck and shoulder disability, headache and smartphone addiction. Logistic regression analysis (sleep disorder, without sleep disorder adults), was performed to analyze factors affecting sleep disorders. RESULTS: Sleep quality index was positively correlated with shoulder pain and disability index(SPADI)-pain score, SPADI-global score and smartphone addiction score. There was a significant difference in SPADI-pain score between the group with sleep disorders and the group without sleep disorders. Shoulder pain and disability were identified as factors affecting sleep disorders. The group with sleep disorders showed 1.088 times more shoulder pain than the group without sleep disorders, and the group with sleep disorders showed 1.006 times higher frequency of shoulder disorders than the group without sleep disorders. CONCLUSION: The results of the present study indicate that as sleep quality worsens, shoulder pain, disability, and smartphone addiction get worse. The group with sleep disorders had significantly increased shoulder pain compared to the group without sleep disorders. We also found that shoulder pain and disability were factors affecting sleep quality. Comparison between intervention method is warranted to better understand adults with sleep disorders.

Purpose: This study was to investigate the correlation between pain, disability and quality of life among adolescents and office workers with neck and shoulder pain. Methods: Twenty-four subjects (mean age=24.92 years, SD=3.94, range=20-37) with neck and shoulder pain participated in this study. The outcome measures of the study were visual analogue scale (VAS), neck disability index (NDI), shoulder pain and disability index (SPADI), short form-36 (SF-36) for neck and shoulder pain and disability, quality of life. Pearson's correlation and Speaman's rank correlation were used to measure the association between VAS and NDI, SPADI, SF-36. Results: The VAS showed a positive correlation between weak to moderate with the NDI and SPADI, but no significantly correlated (${\rho}=0.34$, ${\rho}=0.25$). The moderate positive correlation and significant correlation were observed between NDI and SPADI (${\rho}=0.43$, p<0.05). The PCS of SF-36 was significantly negative correlated with the VAS (${\rho}=-0.24$), NDI and SPADI (${\rho}=-0.63$, ${\rho}=-0.59$, p<0.05). Conclusion: The pain and disability of neck and shoulder has closely relevance. And, the pain and disability of neck and shoulder has a negative impact on the quality of life.

This study examined the effects of a physical therapy program on quality of life (QOL), and neck and shoulder disability in head and neck cancer patients. The program included neck and shoulder range of motion (ROM) exercises, massage, progressive strengthening exercises, and stretching exercises. Sixteen patients who were assigned to an experimental group performed physical therapy for 40 minutes three times a week for eight weeks. Fifteen other patients were assigned to a control group who did not performed the physical therapy program. The European organization for research and treatment of cancer (EORTC QLQ-C30) and head and neck (EORTC QLQ-H&N) instruments, and the Neck Disability Index (NDI) were assessed before and after the rehabilitation program. The 40-minute program consisted of a 10-minute ROM exercise for the neck and shoulder, a 10-minute massage and 15-minute of progressive resistance exercises, followed by a five-minute stretching exercises. Statistically significant differences were noted for changes in global health, physical function in the EORTC QLQ-C30 and cancer related symptoms in the EORTC QLQ-H&N35 (p<.05). The NDI also showed significant differences (p<.05). Physical therapy may therefore benefit the physical aspects and QOL and improve neck and shoulder disability in patients with head and neck cancer.

Purpose: The purpose of this study was to identify the effect of neck exercises on neck-shoulder posture and pain of high school students with neck disorders. Methods: Twenty seven subjects were randomly assigned to one of 3 groups a craniocervical flexion training group (CCFT), a neck strengthening exercise group (ST), and a basic stretching exercise group (CG). CCFT and ST exercised five times a week for eight weeks under the researcher's guidance. The control group performed basic stretching exercises. Diagnostic radiologic equipment was used for the measurement of neck-shoulder posture. Neck disability index, and numeric rating scales were used. Results: The CCFT showed a significant pre-post treatment difference on measures of neck flexion angle and forward shoulder angle changes compared to the ST and CG groups (p<0.05). The CCFT group also showed a significantly greater improvement on the neck disability index and numeric rating scales changes than the ST and CG groups (p<0.01). Conclusion: Because CCFT decreases neck flexion angle, forward shoulder angle, neck disability index, and pain in the forward head posture, it is useful for treating patients with neck disorders.

Purpose: This randomized controlled trial was conducted to compare the effectiveness of global postural reeducation to segmental stretching in subjects with neck and shoulder pain. Methods: Sixteen subjects with neck and shoulder pain were randomized into two intervention groups, a global posture reeducation group (n=8) that performed muscle chain stretching, and a segmental stretching group (n=8) that performed conventional static muscle stretching. The intervention program consisted of two 40 minutes individual sessions per week for four weeks. Subjects were evaluated pre-intervention, two-week after intervention and at a four-week follow-up appointment for pain intensity, disability and health-related quality of life. Two-way repeated analysis of variance was used for between-time and between-group comparisons. The significance level was 0.05. Results: Significant pain relief and decreasing discomfort of the neck and shoulder were observed after intervention in both groups, and there was an interaction between time lapse and groups (pain, F=10.31, neck disability, F=25.45, shoulder disability, F=12.82, p<0.05). Quality of life also improved after intervention in both groups. Moreover, the physical components score improved, and a significant interaction was observed between time and groups (F=4.85, p<0.05). However, no significant improvement in mental component score of quality of life and no significant interaction between time and groups were observed (p>0.05). Conclusion: These findings suggest that a GPR intervention in subjects with neck and shoulder pain induces greater improvement of pain and disability and quality of life than segmental stretching.

Objective: The forward head posture (FHP) is strongly related to the rounded shoulder posture (RSP), which is associated with shoulder pain. Design: Observational cross sectional study design Methods: A total of 37 were enrolled in the study, 22 individuals with FHP(experimental group) and 15 healthy adults(control group). Correlation with differences between groups was analysed through craniovertebral angle (CVA) representing FHP for both groups, neck disability index (NDI) indicating neck pain, disability of the arm, shoulder and hand (DASH) indicating shoulder pain. Results: There was a significant difference in the results of CVA, NDI, and DASH in FHP and healthy adults (p<0.05). Significant correlations were found between DASH and CVA in FHP participants (r = -0.656, p = 0.001). Also, in the regression analysis results of DASH and CVA, the regression model was found to be suitable and the variation in DASH could be explained by 43% (F = 15.118, p = 0.001). Conclusions: Shoulder pain and neck discomfort are potentially related, and an increase in shoulder pain can increase FHP.

Background: The purpose of this study is to investigate the effect of neck and shoulder self-stretching exercise using audiovisual media on neck pain, postural alignment, and joint position error in women with chronic neck pain. Methods: The subjects included 20 women that gave consent to participate in the study voluntarily. They performed the self-stretching exercises using audiovisual media was carried out 20 minutes 5 times a week during 3 weeks. Neck disability index (NDI) and visual analogue scale (VAS) were used to measure the functional disability and pain, A pressure pain threshold was measured using an algometer, and a cervical range of motion (CROM) measurement tool was used to measure the range of motion and error of proprioceptive position sense of the cervical spine. To assess posture alignment, forward head angle (FHA), forward shoulder angle (FSA) were measured using image J software. Results: The neck pain intensity was statistically significantly within group (p<.05). Neck and shoulder functional disability were a statistically significant difference within group (p<.05). Splenius capitis and upper trapezius pressure pain threshold were statistically significant difference in within group (p<.05). The postural alignment was statistically significantly within group (p<.05). The cervical range of motion in neck extension, right and left lateral flexion were statistically significantly within group (p<.05). The joint position error in neck flexion, extension, right and left lateral flexion decreased statistically significantly within group (p<.05). Conclusion: Self-stretching exercise using audiovisual media increased the mobility of the neck, decreased neck pain and joint position error, and improved posture alignment. As a result, there was a positive effect by applying the self-stretching exercise using audiovisual media to people with neck pain. Based on this, it is thought that it can be used as the basis for research related to home training programs for healthy self-management.
