These days, people spend more time sitting at a desk for studies or work. Also, because people continue to use computers, smartphones, and tablet PCs often during break times, their posture is getting worse. Maintaining a position of bad posture for an extended period of time causes problems with the musculoskeletal system related to the neck, shoulders, and spine. Additionally, problems such as physical fatigue and posture deformation are predicted to expand to a wide range of age groups. Therefore, the core function of the system we are developing is to ensure correct sitting posture and to receive alert notifications via the created mobile application. To create the system, a flex sensor, pressure sensor, and tilt sensor are attached to a chair and utilized. The flex sensor detects and compares the amount of bending in the chair's posture and transmits this value to an Arduino Uno R3 board. Additionally, information such as body balance and incline angle are collected to determine whether or not the current sitting posture is correct. When the posture is incorrect, a notification is sent through the mobile application to indicate to the user and the monitoring app that their posture is not correct. The system proposed in this study is expected to be of great help in future posture-related research.

This research was performed to investigate protective effect of Sophora Subprostrata fractions against focal ischemic brain damage after middle cerebral artery(MCA) occlusion. Rats were divided into six groups: MCA-occluded group(Control); each administered groups with Sophora Subprostrata total phase(Total), Sophora Subprostrata Aqueous phase (Aqueous), Sophora Subprostrata BuOH phase(BuOH), and Sophora Subprostrata Alkaloid phase(Alkaloid) after MCA-occlusion; sham-operated group(Sham). The right MCA was occluded by A poly-L-lysine coated 4-0 nylon suture thread through the internal carotid artery permanently. Sophora Subprostrata and fractions were administered orally(5mg/ml) for 7 days after MCA-occlusion. The behavior of ischemic rats were examined at 24 hours, 3, 5 and 7 days after MCA-occlusion from the views of 4 different aspects: posture & balance tests(4 subtests), reflex tests(6 subtests), muscle-tone tests(3 subtests), and foot-fault test. The results showed that 1) in muscle tone test, Sophora Subprostrata total phase only increased reduced muscle tone function from 3 to 7 days, 2) in reflex test, Sophora Subprostrata total and Aqueous phase increased fast recovery from 24 hours and 3 days, 3) in posture & balance test, Sophora Subprostrata total and Aqueous phase increased fast recovery from 24 hours, and Sophora Subprostrata BuOH and Alkaloid phase increased posture & balance function from 3 days, but 4) in motor function test, Sophora Subprostrata did not show effective recovery compared with control group. In conclusion, Sophora Subprostrata has protective effects against brain damage at the early stage of focal cerebral ischemia. Sophora Subprostrata total and Aqueous phase produced more pronounced protective effect against focal ischemic brain damage.

PURPOSE: This study was conducted to investigate the effects of non-elastic and elastic tapes on pain, craniovertebral angle, and balance in forward head posture (FHP) patients. METHODS: A total of 44 adults with FHP were randomly assigned to a group that performed a stretching exercise after non-elastic taping (n = 22) and another group that performed the stretching exercise after elastic taping (n = 22), respectively. The stretching exercise was performed five times a week for 30 minutes per session. The visual analogue scale was used to compare neck pain, the craniovertebral angle was measured to compare alignment, and the limit of stability was measured to compare balance. RESULTS: The groups that performed the stretching exercise after both elastic and non-elastic taping showed significant positive changes in pain and the craniovertebral angle of the head in pre- post measurements (p < .05). In the follow-up test for the pain and craniovertebral angle, there was no significant difference from the post-test in the non-elastic group (p > .05), but a significant difference was seen in the elastic group (p < .05). CONCLUSION: Stretching exercises with taping for patients with a FHP are more effective in improving pain and alignment. However, the short-duration tape application did not affect the balancing ability. When the non-elastic tape was used, the effect lasted longer than that of the elastic tape, and pain relief was effective in the case of the elastic tape. Therefore, tape therapy would be more effective if customized according to the patient's condition.

Objectives This study was designed to investigate the correlation between the difference of pelvic height and difference of gait balance. Methods 62 cases of patients who received treatment from January 2011 to March 2014 for abnormal postures were analyzed. Their difference of pelvic height were estimated by whole spine X-ray analysis and gait balance were estimated by Treadmill Gait Analysis system. The data were analyzed to find out correlation between difference of pelvic height and difference of gait balance, and correlation between the position of pelvic tilt and gait balance higher side. Pearson correlation and Chi-square analysis were used. Results Pelvic height heigher side were more left than right side, and gait balance higher side were also more left than right side. Difference of pelvic height and difference of gait balance had a positive linear relationship, but there was no significant correlation. The position of pelvic tilt had significant correlation with gait balance higher side. Conclusions The position of pelvic tilt had significant correlation with gait balance higher side and difference of pelvic height had no significant correlation with difference of gait balance.

Purpose: This study examined the effects of transcranial direct current stimulation (tDCS) on the static balance ability of patients with back pain. Methods: The subjects comprised of 30 males and females in their 20s, who were divided into two groups with and without tDCS. The balance posture ratio score was calculated to determine the changes in balance ability before and after the application of tDCS using balance equipment. A paired t-test was conducted to determine the changes over time, and an independent t-test was performed to determine the changes between the groups. The significance level was set to ${\alpha}=0.05$. Results: A significant difference in the changes in the static balance ability of CTDCSG between before and after applying tDCS was observed while the subjects' eyes were open (p<0.05). A comparison between the groups after the experiments revealed significantly increased changes in CTDCSG compared to STDCSE (p<0.05). The changes in static balance ability were not significant when the subjects' eyes were closed (p>0.05). Conclusion: The application of tDCS positively changed the static balance ability of patients with back pain. The results of this study showed that tDCS could be used as an intervention to increase the static balance ability of patients with back pain in the clinical field. The study results could be used further as foundational data for future studies on tDCS.

This study was conducted to investigate the effects of therapeutic climbing training on postural alignment and balance of normal adults and to suggest possibilities for clinical intervention. The study investigated 30 normal adults who were randomly assigned to either a training group or a control group (n= 15 each). The training group performed climbing training on the climbing wall three times a week for 6 weeks for a total of 40 minutes, while the control group did not perform any training. Biorecue was used to evaluate balance ability, while formetric was used for evaluation of postural alignment. The results showed that there was a significant difference in body slope between the groups in posture alignment (p<.05), as well as in balance ability (p<.05) and time and group interaction (p<.05). In this study, climbing training affected the posture alignment of normal adults, increased the left and right torso tilt and positively affected balance ability. Therefore, these findings confirm that training using climbing is valuable for rehabilitation and clinical application intervention of the general public and patients.

This study was conducted to examine the influence and effect of muscle enforcement program on Activity of daily living(ADL) improvement and posture balance of the old, and to provide more effective muscle enforcement program and educational data. The muscle enforcement exercise program was performed on the old(institution, 16 men, 10 women) for 8 weeks from April 22, 2002 through June 17,2002. Programed Exercise 1 - Exercise 10 were practised 8 times per program for 3 days a week. The load of exercise was increased per two weeks. The methods of measurement were questionnaire, Indiana 47903(action-response analysis machine) and Sample exercise protocol for KAT 2000(balance training device). SAS/PC statistic analysis was used for data analysis. T-test was used for analysis of change before and after exercise in this study. The summary and conclusions are as follows. 1. On subjectively recognized health states, the healthy were $42.3\%$. On the satisfaction with health states, the satisfied were $50.0\%$. On the factors of effects on daily-life behavior performance, the group who had troubles was $50\%$ and the group who was so and so was $34.6\%$ compared with the old of the same age. On prospect about health states in the future, the group who would be better was $38.\%$. On effective methods for problem solving, exercise was $42.3\%.\;88.5\%$ of respondents answered the need of health care. The participation intention in health program was $92.3\%$. 2. On the change of psychological emotion and behavior aspects, the group who had repeated complaints or anxieties and reduced activities or interests was effective(P<0.01). 3. On the improvement effects of IADL difficulties, the group who had difficulties in doing daily-life indoors was improved effectively compared with before and after exercise(P<0.01). On medication management, the effects of improvement after exercise were high compared with before exercise(P<0.01), the effects of improvement was high on the whole. 4. On the effects of ADL function improvement, putting on upper clothing and lower clothing was improved effectively(P<0.05), toilet use and individual sanitation was improved effectively(P<0.05). 5. On the effects of action-response, the results of 8weeks regular exercise program were not different significantly compared with before and after exercise. The behavior quickness of the old by muscle enforcement program was not increased. This means that the old needs much time for exercise sense training because of the regression of cognition sense. 6. In the effect of posture balance, the whole grades were effective from 1272.69 before excercise to 476.92 after exercise(P<0.01). Especially right balance 657.65 was lowered to 208.57 after exercise most effectively(P<0.01). Rear balance 776.34 before exercise was lowered to 136.65 after exercise. The results of measurement were significant(P<0.05).

Many people do not realize that they have poor neck posture. Incorrect forward head posture can lead to turtle neck. This aim to development of specific chair to reduce tension and other symptoms of turtle neck posture. This turtle neck syndrome adjusting chair is a chair that supports the hip and shin of a person to help them correct their posture. It is consisted of the shin support that supports the shin in an angle and the hip support that supports one's hip while the shin is supported at an angle, the main frame that has the two of them connected and the fluid seat that is joined at the top of the hip support and reacts accordingly to the shape of the hip. This is a posture correction chair which has the fluid seat that provides unstable hip support so that it can allow a person to realize their posture from the constant stimulation about the posture. When one seats on the posture correction chair, their hip and shin are supported at an angle that straitens their back, and as their back is straightened, their shoulders and chest are opened, and the neck is positioned at the middle to help them correct their posture. An unbalanced posture causes discomfort to the person seated at the chair, and the person sitting on the posture correction chair will continuously adjust his/her posture to balance the hips to keep the correct posture. Through this process, the person shall adjust his/her left and right posture, ultimately increasing the effectiveness of posture correction. A future collective study on the continuous posture correction of people having turtle neck syndrome using this posture correction chair is required.
