The purpose of this study was to identify the effect of upper thoracic mobilization on cervical alignment in stroke patients with forward head posture. The subject's of this study were two stroke patients with forward head posture and a cervical curve angle (four-line Cobb's method; FLCM) less than $40^{\circ}$. The intervention, central posterior-anterior (PA) mobilization, was applied to the T1-T4 vertebrae (upper thoracic spine) following the Maitland concept. This mobilization was applied three times per week for four weeks. In the results, the cervical curve angle (FLCM) increased for both subject 1 and 2. However, Jochumsen method score was decreased in subject 1, while it was increased in subject 2. These results demonstrate that upper thoracic mobilization had the positive effect on the cervical curve angle but not on Jochumsen method score. These findings suggest that PA mobilization on the upper thoracic spine could correct cervical curve angle measured by FLMC in stroke patients with FHP.

The purpose of this study was to investigate the relationship of the head posture with the tone and stiffness of the cervical extensor muscles. Eighty adults in their twenties were chosen as subjects, and the tone and stiffness of the cervical extensor muscles were measured, with their usual head posture in the sagittal plane. For the measured head posture, the craniovertebral angle (CVA), craniorotation angle (CRA), and forward shoulder angle (FSA) were analyzed using Image J. It was observed that the tone and stiffness of the upper trapezius muscle increased significantly with a decrease in the CVA as well as with an increase in the CRA (p < 0.05). As a result of further classification into the normal and forward head postures based on the CVA of the subjects, the forward head posture was characterized by a significant increase in the tone and stiffness of the upper trapezius muscle (p<.05). The results of this study are expected to be used as basic data for the evaluation of the forward head posture and posture education in clinical practice.

I. Purpose The dose distribution in normal tissues and target lesions is very important in the treatment planning. To make the uniform dose distribution in target lesions, many methods has been used. Especially in the head and neck, the dose inhomogeneity at the skin surface should be corrected. Conventional methods have a limitation in delivering the enough doses to the planning target volume (PTV) with minimized dose to the parotid gland and spinal cord. In this study, we investigated the feasibility and the practical QA methods of the forward IMRT. II. Material and Methods The treatment plan of the forward IMRT with the partial block technique using the dynamic multi-leaf collimator (dMLC) for the patients with the nasopharyngeal cancer was verified using the dose volume histogram (DVH). The films and pinpoint chamber were used for the accurate dose verification. III. Results As a result of verifying the DVH for the 2-D treatment plan with the forward IMRT, the dose to the both parotid gland and spinal cord were reduced. So the forward IMRT could save the normal tissues and optimize the treatment. Forward IMRT can use the 3-D treatment planning system and easily assure the quality, so it is easily accessible comparing with inverse IMRT IV. Conclusion The forward IMRT could make the uniform dose in the PTV while maintaining under the tolerance dose in the normal tissues comparing with the 2-D treatment.

Background: The purpose of this case study was to investigate into the effect of complex exercise program on the postural change, gait and balance ability in elementary school students with forward head posture. Methods: Four patients with forward head posture were recruited. They were evaluated pre-treatment, and after 6weeks, using neck disability index (NDI), numeric pain rating scale (NPRS), balance ability, foot pressure (fore foot/rear foot peak pressure ratio, F/R ratio), gait ability (cadence, toe out angle, stance phase). Results: First, the angle of forward head posture (craniovertebral angle; CVA and cranialrotation angle; CRA) was decreased in all subjects. The NPRS and NDI were decreased in all subjects. Also, The cadence, toe out angle and F/R ratio were increased in all subjects. The stance phase of gait cycle was positively change in all subjects. Lastly, the static balance ability improved in all subjects. Conclusion: According to the results above, the complex exercise program for students with forward head posture can help improve the postural change, gait and balance ability. Also, the complex exercise program was able to select interventions depending on the patient's condition and the desired goal.

Background: Because a forward-leaning posture can cause increased back muscle activity and pain. Therefore, an innovative method to reduce back muscle activity and pain is required. Objects: This study aimed to investigate the effects of a head support on muscle activity and pain in a forward-leaning posture. Methods: A total of 14 male and 16 female students (average age, 21.65 ± 2.37 years; height, 166.15 ± 7.90 cm; and weight, 60.65 ± 9.00 kg) were recruited for the experiment. Two of them were excluded due to musculoskeletal disorders. The muscle activity and pain in the forward-leaning posture were assessed while participants washed dishes for 7 minutes with and without a head support. The condition of using a head support was randomly performed with a 5-minutes break. To confirm a lumbar flexion angle of 30° during the experiment, myoVIDEO was used, and surface electromyography was used to measure muscle activity. Pain was assessed using a 10-point visual analog scale (VAS). The Wilcoxon signed-rank test was used to analyze the data, with p < 0.05 indicating statistical significance. Results: The cervical, thoracic, and lumbar erector spinae muscle activities significantly decreased with the use of the head support, but there was no significant change in the gluteus maximus. There was a significant decrease in the VAS score for the lumbar erector spinae (p < 0.05), but there was no significant change in the VAS score for the cervical region. Conclusion: The use of a head support in a forward-leaning posture reduced cervical, thoracic, and lumbar erector muscle activity and pain. Therefore, it could be recommended during working in a forward-leaning posture, such as during dishwashing, cooking, and working as a factory employee.

Purpose: This study attempts to determine the effects of applying three kinds of breathing exercises for four weeks on the neck muscle activation of subjects with a forward head posture. Methods: A total of 30 adults aged in their twenties (15 men and 15 women) with a forward head posture who voluntarily agreed to participate after listening to the purpose and procedure of this research were chosen as the subjects of this study. The subjects were randomly divided into either the diaphragmatic breathing exercise (DBE) group, the abdominal drawing-in maneuver (ADIM) group, or the abdominal expansion method (AEM) group according to the breathing intervention scheme. Each group included ten subjects. The muscle activity of the sternocleidomastoid, scalenus anterior, and splenius capitis was measured in all the groups prior to the intervention, two weeks after the intervention, and four weeks after the intervention. All the interventions were implemented for 30 minutes a day, three times a week, for a total of four weeks. Results: No significant between-group difference was observed in terms of the change in neck muscle activity according to the four-week intervention scheme. Further, there was no interaction between the intervention period and the intervention scheme in relation to the change in neck muscle activity. Conclusion: The results of this study suggest that abdominal expansion exercise is as effective as other breathing exercise methods for subjects with a forward head posture. We therefore expect that abdominal expansion exercise can be used as a scheme for the prevention of symptoms as well as therapy for patients with a forward head posture.

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.

This study was designed to provide basic data for developing exercise program that helps correcting posture by knowing the effect of strengthening and elongation exercises of upper extremity muscle to forward head posture correction. In this study determined subjects whether they had forward head posture or not. On the basis of the New York state posture rating, if a subject's posture is match up with the normal standard posture, gives 5 points and if the posture is slightly get out of the normal standard posture, gives 3 points and if the posture is apparently get out of the standard, gives 1 points. When determining the forward head posture, if talus, humerus and outer ear center are on the same line, it is determined as normal and if outer ear center is off the line less than 1.0cm, it is a slight deformation and if outer ear center is off the line more than 1.0cm, it is a high deformation. In the study selected people who have more than 1 cm gap between two vertical lines start from outer ear center and acromion separately as subjects. Length between the ideal alignment line measured by using goniometer and temporal region showed statistically significant decrease as $2.36{\pm}1.07cm$ before the intervention and $1.06{\pm}0.88cm$ after the intervention. After 4 weeks of neck and chest extensor muscle exercise, the group who exercised both showed increase in range of neck joint motion and neck flexion of the forward head posture. Meanwhile the group who only exercised neck extensor muscle only and the group who only exercised chest extensor muscle didn't showed statistically significant result. That only the group who exercised both muscles showed significant result is the different with studies before. Because this study didn't target patient who had a lesion, couldn't compare effect of the conservative manner and exercise. However, this study provides the fact that the group who exercised both neck and chest muscle had more effect than the control group.

Purpose : The purpose of this study was to investigate the effect of 2 weeks of backward walking exercise (BWE) on cervical angle and gait parameters in college students with forward head posture. Methods : Fifteen subjects participated in the experiment. All the participants had a craniovertebral angle (CVA) of 55 degrees or less. The purpose of the study was explained to all the subjects prior to participation, and volunteered to take part in the study. A camera capable of taking pictures of the lateral plane was installed at a distance of 1.5 meters from each subject. Images of forward head posture were obtained before and after performing the BWE, and the CVA and craniorotational angle (CRA) were compared pre- versus post exercise. Foot pressure and gait parameters (step length of left and right, stride length, stance of left and right, swing of left and right, step time of left and right, and stride time) were measured using a rehabilitation treadmill. The subjects performed the BWE for 2 weeks. The exercise program consisted of a 5-minute warm-up exercise, 20-minute main exercise, and 5-minute cool-down exercise. In the main exercise, the treadmill speed was set to 2.4 km/h in the first week and 3.4 km/h in the second week. A paired t test was used to compare the CVA and CRA and gait parameters before and after the exercise. Results : Comparison of the CVA and CRA before and after the BWE revealed a significant difference post exercise, with a marked improvement in forward head posture after the exercise (p<.05). Conclusion : Based on the results of this study, the BWE is considered to be an effective exercise for the forward head posture. Also, additional research is needed to shed light on the impact of the BWE on gait parameters.
