  • Background: A herniated intervertebral disc (HIVD) triggers low back pain (LBP). Korean conservative treatment can decrease the herniated disc size without traditional surgery, but detailed prognosis is unclear. Case summary: One patient presented with LBP and bilateral sciatica. She was diagnosed with lumbar HIVD by magnetic resonance imaging (MRI) and treated by Korean medicine (acupuncture, decoction, and physical therapy). For 6 months, MRI follow-up exams showed the aggravation and migration of L5-S1 followed by distinct improvement of the same lumbar vertebra. Conclusion: The disc size in a patient with lumbar HIVD was reduced by Korean conservative treatment, and periodic radiologic examination showed the previously unrecognized process of absorbing the disc.

  • 이 연구의 목적은 만성요통 여성 환자들에서 나타나는 자세 이상을 평가하고 방사선적 변수들과 임상적인 변수들과의 상관성을 알아보는 것이다. 이 연구의 대상자는 만성요통 여성 환자 38명과 대조군 32명이었다. 변수의 측정은 모든 대상자들이 이완된 자세로 기립한 상태에서 방사선 검사를 실시한 후 경추전만각, 흉추후만각, 요추전만각, 그리고 요추경사각을 측정하였다. 대상자들의 연령과 통증기간은 의무기록지를 참고하였다. 자료분석은 요통군과 대조군의 방사선적 변수들 간의 유의한 차이가 있는지를 알아보기 위해 독립된 t-검정을 시행하였고, 방사선적 변수들과 임상적 변수들과의 상관성을 알아보기 위해 피어슨 상관분석을 시행하였다. 연구결과 만성요통 환자군과 대조군사이의 경추전만각(p<.05), 요추전만각(p<.001), 그리고 천추경사각(p<.01)에서 통계학적으로 유의한 차이가 보였다. 통증기간은 요추전만각과 통계적학으로 유의한 상관관계가 있었으며(p<.05), 경추전만각은 흉추후만각과 통계학적으로 유의한 상관관계가 있었다(p<.05). 또한 흉추후만각, 요추전만각, 그리고 천추경사각은 각각 상호간에 상관관계가 있었다(p<.05). 만성요통은 요추만곡의 변화를 초래하여 흉추부 및 경추부의 자세이상을 유발할 수 있다. 그러므로 요통으로 인하여 올 수 있는 신체 전반적인 자세이상을 미리 예측하고 이를 교정하여야만 장기적으로 올 수 있는 합병증들을 예방할 수 있을 것이다.

  • The EMG(Electromyography) analysis was used to identify the fact the degree of inclined step was selected as dependent variable and feet muscle fatigue was selected as a independent variable. In a final result from EMG test. the shift in median frequency (MF) with 20, 25, 30, 35 degree of inclined steps indicated that 30 degree step was identified as most effective for a decrease in feet muscle fatigue. In a department store, 80% of the workers are female standing sales workers. They work at standing on average 10 hours per day. They performed heavy duty jobs such as lifting, lowering. packing and carrying heavy materials. Furthermore, even though they have work shoes, they usually use various kind of high heels. Eventually, this situation develops low-back-pain (LBP) problems for female workers. In conclusion, it is recommended that a particular branch in a department store claimed this step can effectively to circulate blood and significantly decrease feet muscle fatigue in lower extremity.

  • The objective of this study is to survey the working environmental conditions and musculoskeletal workload(DMQ) in red pepper farmers. 155 full-time farmers(males=91, females=64) lived in Chungnam and Jeonbuk participated in the study. To offer the fundamental data for agricultural improvement of red pepper farms, information about working farm conditions, health condition, musculoskeletal disorders(MSDs), labor intensity and musculoskeletal workload was obtained by questionnaire and interviews. The results are as follows: 1. The farmers reported sunlights, high temperature and cold/ draught as uncomfortable work environment. 2. Physical and mental fatigue in females is higher than that of males. 3. The prevalence rates of medical diagnosed diseases are higher in order of osteoarthritis, herniated nucleus pulposus(HNP), and chronic gastritis/gastric ulcer. 4. Prevalence rates of musculoskeletal symptoms more than standard 1 among the various pain areas are higher in order of low back, shoulders and knees. These results can be used practically for agricultural improvement of red pepper farms to prevent MSDs.

  • Objective : The purpose of this study was to suggest (diagnostic) criteria for lumbar disc space and see the correlation between lumbar disc space narrowing and the level of HIVD. Methods : We looked at the 113 patients diagnosed disc space narrowing with lumbar x-ray and MRI films who have visited Jaseng Hospital of Oriental Medicine with low back pain in October,2013. The width of lumbar disc space and the severity of Herniated Intervertebral Disc(HIVD) on MRI films were collected and stastically analyzed using one-way ANOVA. Results : In this study, measured value(%) for lumbar disc space of the group diagnosed serious HIVD, such as protrusion, extrusion and migration was significantly decresed compared to the normal group and the bulging group. Conclusion : There was a significant correlation between lumbar disc space narrowing and the level of HIVD.

  • In recent years, the increasing interest in health-care requires the industrial products to be well-designed ergonomically. In the commercial vehicle industry, several researchers have demonstrated the driver's posture has great effect on the orthopedic desease such as fatigue, back pain, scoliosis, and so on. However, the existing sensor systems developed for measuring the driver posture in real time have suffered from inaccuracy and low reliability issues. Here, we suggest our smart vehicle seat system capable of real-time driver posture monitoring by using the air bag sensor package with high sensitivity and reliability. The ergonomic numerical model which can evaluate a driver's posture has been developed on the basis of the human body segmentation method followed by simulation-based validation. Our experimental analysis of obtained pressure distribution of a vehicle seat under the different driver's postures revealed our smart vehicle system successfully achieved the driver's real-time posture data in great agreement with our numerical model.

  • Low back pain is one of major issues in musculoskeletal diseases mainly caused by MMH (Manual Material Handling) tasks. In Korea, the standards of NIOSH(National Institute for Occupational Safety and Health) Lift Equations in U. S. A. have been most widely used. However, there is no standard in case the height of one feet is higher than that of another one. Moreover, since the standards are developed in U. S. A., there are many limitations for the applicability of Korean workers. In this study, MVC(Maximum Voluntary Contraction) for four postures are measured and an empirical model based on SVR(Support Vector Regression) is constructed. Constructing SVR model, PSO(Particle Swarm Optimization) is employed to investigate the optimal parameters of SVR. The results show that the performance of this empirical model is approximately accurate, even if the deviation of experimental values is large due to the individual differences. This empirical model may contribute to establish the standards of MMH tasks in Korea.
