This study was performed to measure the posture correction effect of wearing ergonomic experimental clothing. Two types of experimental clothing (A, B) were developed. Both of them reinforced the muscles surrounding the spine. Experimental clothing A was developed by reflecting the shape and position of the pectoralis major muscle, abdominal muscle, and latissimus dorsi muscle. Experiment clothing B was developed by reflecting the integrated form of those muscles. Subjects were males in their 20s~30s (n=32). They were divided into two groups based on their acromion distance (AD): the turtle neck syndrome group (n=16, AD=3.81cm) and the normal group (n=16, AD=1.27cm). The correction of body posture was detected by three index values: change of the cervical curvature angle, horizontal distance between the seventh cervical vertebra and tragion, and AD. The comfort and tightness of the clothing were also measured. The results showed that both types of experimental clothing corrected body posture and that turtle neck syndrome can be prevented by wearing these types of posture correcting clothing. Two index values were decreased: cervical curvature angle ($0.31{\sim}1.32^{\circ}$) and horizontal distance between seventh cervical vertebra and tragion (0.22~0.31cm). The chest was also stretched. The comfort was rated as good for both types of experimental clothing. These results indicate that the experimental clothing had a posture correction effect without any discomfort for daily living.

This study develops a t-shirt design that align bones and balance muscles in order to maintain proper posture using the basic concepts of symmetry. First, theoretical and 3D design studies, existing literature on proper and improper posture, and the basic concepts of symmetry are studied to create the design. Next, the 3D design process applies bilateral, rotational, and scaling symmetries to design the inner lines from the basic application of symmetry. A two-stage design process is used, whereby the strain map and pressure points are analyzed using the CLO virtual clothing software, and the most effective design is determined through virtual testing. The results show that the Y+)( and X+― design, which combines the position and type of inner lines, is the most effective for posture correction and maintenance. Overall, this study helps create a theoretical and practical basis for exploring and understanding basic lines appropriate for the human body, and subsequently, for developing various products that maintain posture more accurately and precisely.

This study developed a responsive healthcare system that users can easily use in real life to prevent turtle neck syndrome by posture correction. We propose a system that naturally induces direct posture improvement by adjusting the height with a responsive cradle through a turtle neck discrimination algorithm detecting the turtle neck posture in real time using a webcam. The turtle neck algorithm was developed based on machine learning, using the points that the distance relationship between the jaw line and the shoulder varies depending on the posture. For the younger age group, which is particularly problematic due to the increase in the use of IT devices, image data in different situations according to the height and posture of the cradle was collected and learned as a support vector machine classifier. In addition, a height-adjustable cradle that can support a laptop has been created and expanded into a responsive cradle that can be controlled with software by interlocking with the Arduino. Therefore, this service enables posture correction of many modern people suffering from turtle neck syndrome and will become an essential platform in the increasing online environment in the non-contact era.

Purpose: The purpose of this study was to investigate the effects of neck stabilization exercise with PNF for neck alignment, neck disability index, and sitting balance in adults with forward-head posture. Methods: Forty participants were randomly assigned to two groups. Patients in the neck stabilization exercise group (NSG, n = 20) and the proprioceptive neuromuscular facilitation neck pattern exercise group (PNFG, n = 20) were studied 30 minutes a day three times a week for four weeks. Outcomes were measured using cranial vertical angle (CVA), the Korean version of the neck disability index (KNDI), anterior limit of stability (ALOS), and posterior limit of stability (PLOS) before and after the intervention period. Results: There were significant effects in the CVA and the KNDI of both groups pre- and post-intervention. There were significant effects in ALOS and PLOS in the PNFG pre- and post-intervention compared with the NSG. Conclusion: The results of this study suggest that PNF with neck exercise could be beneficial to the static balance of adults with 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.

Background: This study was carried out to compare the effects of shoulder stabilization exercise and thoracic extension exercise including deep neck flexor exercise on posture and pain targeting physical therapists and occupational therapists with forward head posture. Methods: A total of 30 physical therapists and occupational therapists (15 males, 15 females), who are working in the nursing hospital at Daejeon, were randomly divided into a shoulder stabilization group (n=10), a thoracic extension exercise (n=10), and a control group (n=10), and 3 times were carried out for 8 weeks. Results: In the results of all measurements, 2 groups except for the control group showed a significant change in the recovery of forward head posture, and the should stabilization exercise group showed a relatively superior effect compared to the thoracic extension exercise group. Conclusions: These results of a study will be a basic data for the development of the forward head posture exercise therapy program.

Purpose : The purpose of this study was to investigate the impact of postural correction training on pulmonary function on 28 college students suspected of turtle neck syndrome, and the following conclusions were obtained. Methods : Turtle neck syndrome suspicion 28 person were randomly divided into a posture training group (n = 14) and group that does not perform posture training (n = 14). Respiratory function was measured by SPIROVIT SP-1 and respiratory gas analyzer. The posture training group performed balloon blowing and stair climbing after 20 minutes of posture training, and the group without posture training carried out balloon blowing training and stair climbing. Five times a week and for two weeks. Results : 1. The comparison of the FVC before and after experiments caused by balloon blowing showed a higher level of effortful pulmonary function in the control group than in the experimental group. 2. Comparison of PEFs before and after the experiment by balloon blowing showed that the experimental group's peak flow rate was higher than that of the control group. 3. Comparison of the FIVC before and after experiments with balloon blowing showed that the comparison of the FIVC showed a higher level of effortless intake pulmonary function in the control group than in the experimental group. 4. The comparison of the maximum ventilation volume(VE) before and after the experimental gas measurement showed that the maximum ventilation rate of the experimental group was higher than that of the control group. 5. The comparison of pre-test and post-test heart rate(HR) by breath gas measurement showed that the heart rate of the control group was higher than that of the experimental group. Conclusion : the results of this study showed that postural correction training, balloon blowing training, and stair climbing could have a positive impact on improving pulmonary function. However, the two-week experiment conducted five times a week showed an increase in pulmonary function, but it was difficult to see the effect due to the short study period. Therefore, it is hoped that later studies will be conducted more systematically on the effects of breathing exercises on improving pulmonary function after post-postural correction training for patients with pulmonary function problems.
