Objective: The purpose of this study was to investigate the effects of sling exercise on the cervical lordotic angle, craniovertebral angle, and head rotation angle among adolescents in the forward head posture. Methods: The subjects include 22 adolescents that recorded a mild level or higher on the posture evaluation index by New York State. They were randomly divided to the hand exercise group (n=11) and the control group (n=11). The former group participated in the sling exercise program three times a week over four weeks in total with each session lasting 60 minutes, whereas the latter group was not included in the program. The cervical lordotic angle, craniovertebral angle, and head rotation angle were measured before and after the intervention. Results: The study compared the cervical lordotic angle between the two groups before and after sling exercise and found that the sling exercise group made an increase of $7.36^{\circ}$ from $21.91^{\circ}$ to $29.27^{\circ}$ after the intervention(p<.05). As for the comparison results of the craniovertebral angle, the sling exercise group made an increase of $5.64^{\circ}$ from $48.91^{\circ}$ to $54.55^{\circ}$ after the intervention (p<.05). As for the comparison results of the cranial-rotation angle, the sling exercise group made an decrease of $-7.73^{\circ}$ from $148.82^{\circ}$ to $141.09^{\circ}$ after the intervention (p<.05). The control group showed no differences before and after the intervention (p>.05). Conclusion: Those findings indicate that the application of sling exercise in the forward head posture can be a good program to maintain the right posture and improve or prevent an abnormal posture and raise a need for more clinical applications and ongoing researches.

PURPOSE: We investigated the relationship between the segment of erector spinae during a core stability exercise according to visual control. METHODS: The subjects of this study were 20 healthy students. An 8-channel electromyograph was used to measure muscle activities of the erector spinae by segment(cervical, thoracic and lumbar) during a core stability exercise according to visual control. The collected data were analyzed using the independent t-test and Pearson-test. RESULTS: The activity of the erector spinae for all segment was higher without the vision than with. The activity of right cervical erector spinae was significantly increased by increasing the activity of the left thoracic erector spinae during a core stability exercise with vision (r= .555). The activity of left thoracic erector spinae was significantly increased by increasing the activity of the left lumbar erector spinae during a core stability exercise without vision (r= .472). CONCLUSION: There was a positive correlation between the cervical and thoracic segment of erector spinae during a core stability exercise with vision. There was a positive correlation between the thoracic and lumbar segment of erector spinae during a core stability exercise without vision.

Objective: Cervical stabilization exercises are frequently to improve strength and endurance of cervical muscles. The purpose of this study was to identify changes in head repositioning accuracy (HRA) and neck proprioception through cervical stabilization exercises in healthy adults. Design: One group pretest-posttest design. Methods: Thirteen participants with no previous history of neck pain or injury to the cervical spine were recruited. HRA was measured by equipment including laser pointer, helmet, eye patch and marking pens. The distance between the spot where the beam had stopped and the center of the graph paper was measured three times with the averaged value used as the head repositioning accuracy. Neck proprioception was measured by a cervical range of motion device (CROM). Subjects wore the CROM tester and were to look straight ahead while bending his/her neck. Subjects were instructed to perform extension, lateral flexion and rotation, and the values were then measured and recorded. The measurements were performed pre-intervention, and after cervical stabilization exercise. Results: There was no significant difference on HRA after intervention. In addition, there was no significant difference on neck proprioception compared with pre-intervention. Conclusions: The present study did not identify any effect on HRA and neck proprioception of cervical stabilization exercise. Further investigations are required to elucidate this in old aged participants and patients with neck pain.

Purpose: The purpose of this study was to compare the effects of new exercises (combined cervical and thoracic extension exercises) with those of conventional cervical extensor strengthening exercises (sitting cervical extension exercises) and thoracic extensor strengthening exercises (prone thoracic extension exercises). Method: Fifteen healthy subjects performed sitting cervical extension exercises, prone thoracic extension exercises, and combined cervical and thoracic extension exercises. During each exercise, electromyography was used to measure muscle activity in the erector spinae with C4 and T4 levels. The measured data were analyzed using one-way repeated analysis of variance. Results: With different exercises, there were significant differences in activity in the erector spinae muscle (p < 0.05). The activity in the erector spinae muscle increased significantly during the combined cervical and thoracic extension exercises compared to the sitting cervical extension (p < 0.05) and prone thoracic extension exercises (p < 0.05). The sitting cervical extension exercises significantly increased activity in the cervical erector spinae muscle compared to the prone thoracic extension exercises (p < 0.05). Activity in the thoracic erector spinae muscles was significantly increased during the prone thoracic extension exercises compared to during the sitting cervical extension exercises (p < 0.05). Conclusion: These findings suggest that the newer exercises effectively increase activity in the cervical and thoracic extensor muscles.

We researched two patients complaining about chronic neck pain with kyphotic cervical curvature. We assumed that the patients' symptom was caused by weakened deep neck flexor and activated superficial muscles around neck. So, acupuncture therapy, SCENAR therapy and self exercise with wooden neck pillow were used to treat the patients. We measured their pain by numerical rating scale (NRS) and neck disability index (NDI) before and after treatment. And cervical curvature was evaluated by Cobb method (C1-C7) and Ishihara Index. As a result, NRS and NDI significantly reduced and cervical curvature was also improved. Therefore, we conclude that acupuncture therapy with SCENAR therapy and self exercise using wooden neck pillow is an effective treatment to reduce chronic neck pain with kyphotic cervical curvature. But there is a limit on this study due to insufficient number of cases and absence of control group. Further studies will be needed.

PURPOSE: This study examined the effects of an exercise program for the thoracic spine and scapula rather than the neck, which is the primary site of pain. METHODS: Thirty-two elementary school teachers with a forward head posture (FHP) were assigned randomly to either the experimental group (n = 16) or the control group (n = 16). The experimental group performed scapular stabilization exercise (SSE) and thoracic extension exercise (TEE), and the control group performed cervical self-myofascial release exercise and stretching exercise. The pulmonary functions, pain, craniovertebral angle (CVA), and cervical range of motion (CROM) were measured before the intervention and six weeks after. RESULTS: The within-group comparisons showed that the VAS and CROM (except for extension) in both groups were significantly different before and after the intervention (p < .05). The changes in the maximum inspiratory pressure (MIP), maximum expiratory pressure (MEP), forced vital capacity (FVC), forced expiratory volume at 1 sec (FEV1), and CVA were significant only in the experimental group (p < .05). The between-group comparisons showed a significant difference in the FVC, FEV1, VAS, CVA, and left lateral flexion (p < .05). CONCLUSION: The combination of SSE and TEE in the experimental group was more effective in improving the FHP and breathing ability. Moreover, the experimental group and control combination appeared to be effective in reducing pain and improving the CROM. The combination of SSE and TEE, which are exercises that do not target the cervical spine directly, was effective in improving the posture, respiration, neck pain, and CROM in elementary school teachers with FHP.

Purpose : The purpose of this study was to provide an effective method of exercise therapy for patients with cervicogenic headache. Methods : The subjects were divided into the following two groups according to the intervention received: cervical stretch exercise (n=15, control group) cervix-stabilizing exercise (n=15, experimental group) tone (Hz) and stiffness (N/m) of the suboccipital and upper trapezius muscles were measured. T1 slope angle and neck tilt angle were measured. After the exercise program intervention, a greater amount of change in muscle tone and stiffness of suboccipital and upper trapezius muscles was found in the experimental group, as compared to the control group. Greater amount of change in posture was found in the experimental group, as compared to the control group (p<0.05). Results : After the exercise program intervention, a greater amount of change in muscle tone and stiffness of suboccipital and upper trapezius muscles was found in the experimental group, as compared to the control group. Greater amount of change in posture was found in the experimental group, as compared to the control group (p<0.05). Conclusion : The neck-stabilizing exercise were shown to be effective in decreasing the tone of the cervical muscles by stabilizing the cervical bone and improving muscle activity, and in improving the posture by decreasing muscle tone and stiffness.

PURPOSE: Forward head posture and turtle neck are common musculoskeletal disorders of the cervical vertebrae. The purpose of this study was to investigate the effects of combined exercise training and chiropractic on the grip strength and cervical muscle strength of subjects with forward head posture and turtle neck. METHODS: The subjects were divided into two groups: forward head posture (n=9) and turtle neck (n=9). Both groups performed combined exercise training and chiropractic. The subjects were instructed about the exercise training once a week. This training was performed for 30 minutes every day for 8 weeks, and the chiropractic was performed for 15 minutes once a week. The cervical muscle strength and grip strength were measured. Two-way repeated measured ANOVA was performed for statistical analysis. RESULTS: In changes to the left grip strength, the main effect over time was significant, but the interaction effect and the main effect in the groups were not significant. In changes to the right grip strength, no difference was found to be statistically significant. In changes to the cervical muscle strength, no difference was found to be statistically significant. CONCLUSION: The increases of grips strengths and cervical muscle strength in forward head posture group were greater than turtle neck group but there were not found to be statistically significant.
