Objectives : The purpose of this study was to evaluate the effect of Oriental medical treatment in patients with acute lumbar Herniated Intervertebral Disc(HIVD). Methods : This clinical study was carried out on 44 patients with acute lumbar HIVD, who had been admitted from Oct. 2011 to Nov. 2011. All of 44 patients were treated with acupuncture, Chuna treatment and herbal medicine during the whole admission period. Verbal numerical rating scale(VNRS) and Oswestry disability index(ODI) were used to evaluated the effectiveness of the Oriental medical treatment. Result : Siginificant improvement of the symptoms was seen when evaluated with VNRS and ODI. Conclusions : These results suggest that in the case of low back pain and lower limb numbness caused by acute HIVD, conservative treatments can be considered as one of the options of treating the symptoms beside surgical way.

Objectives: The aim of this study was to analyse the domestic trends of Chuna treatments techniques in Korean literature. Methods: We searched the clinical trials on Chuna treatments through both electronic search(used keyword 'chuna') and hand search in 3 Korean web databases(OASIS, NDSL, RISS) and 4 related journals(The Journal of Korea CHUNA Manual Medicine for Spine & Nerves, Journal of Oriental Rehabilitation Medicine, The Journal of Korean Acupuncture & Moxibustion Society, Journal of Korean Medicine Society). All relevant clinical trials were selected and extracted to be analyzed according to their published year, journals, types of study, used techniques. Results: The number of the clinical studies tends to increase every year. The studies on Chuna treatments were mainly published in The Journal of Korea Chuna Manual Medicine for Spine & Nerves. In case of types of study, case reports and case series were predominant. The most frequently adopted techniques of Chuna in studies were flexion distraction technique for lumbar spine and JS supine position cervical spine distraction. Conclusions: Through the results of this study, we hope that the more qualitative education could be conducted by strengthening the techniques which often used. Also analysis of the reason of rarely used techniques should be conducted and the modification or developing techinques should be followed as a counter measures. As applying more rigorous methodology, more qualitative evidence based Chuna studies should be conducted in future clinical research.

In this study, lower extremity joint kinematics and kinetics and lumbar lordosis were investigated for two different symmetrical lifting techniques(squat and stoop) using the three-dimensional motion analysis. Twenty-six male volunteers lifted boxes weighing 5, 10 and 15kg by both squat and stoop lifting techniques. There were not significant differences in maximum lumbar joint moments between the two techniques. The hip and ankle contributed the most part of the support moments during squat lifting, and the knee flexion moment played an important role in stoop lifting. The hip, ankle and lumbar joints generated power and only the khee joint absorbed power in the squat lifting. The knee and ankle joints absorbed power, the hip and lumbar joints generated power in the stoop lifting. The bi-articular antagonist muscles' co-contraction around the knee joint during the squat lifting and the eccentric co-contraction of the gastrocnemius and semitendinosus were found to be important for straightening up during the stoop lifting. At the time of lordotic curvature appearance in the squat lifting, there were significant correlations in all three lower extremity joint moments with the lumbar joint. Differently, only the hip moment had significant correlation with the lumbar joint in the stoop lifting. In conclusion, the knee extension which is prominent kinematics during the squat tilling was produced by the contributions of the kinetic factors from the hip and ankle joints(extensor moment and power generation) and the lumbar extension which is prominent kinematics during the stoop lifting could be produced by the contributions of the knee joint kinetic factors(flexor moment, power absorption, bi-articular muscle function).

My prior questionnaire has applied to 12 male and 29 female adults over 30-69 years old suffering from lumbago fer 6 months at least or having diagnosis of lumbago. I had the following conclusions from physical characteristics and cardiopulmonary capacity of lumbago Patients caused by obesity 1) The rate of lipids in the body was rotated to the maximum heart rate in the male group of lumbago patients (P<0.01). 2) The rate of lipids in the body was related to the maximum intake of oxygen(O2) in the male group of lumbago patients(P<0.01). 3) The maximum heart rae was related to the maximum intake of oxygen in the male group of lumbago patients(P<0.01). 4) The rate of lipids in the body was related to the maximum intake of oxygen in the female group of lumbago patients(P<0.05). 5) The rate of lipids in the body showed no relation to the maximum heart rate in the female group of lumbago patients(P>0.05). 6) The maximum heart rate was related to the maximum intake of oxygen in the female group of lumbago patients(P<0.01). 7) The cardiovascular system showed no relation te the function of the lungs in the male and female groups of lumbago patients(P>0.05) 8) The lung capacity per second of lumbago patients(FEV $1.0\%$) measured less than normal adults. 9) The maximum intake of oxygen(V02max) and heart rate was less than normal adults. Thus I summarized the conclusion so follows: the cardiovascular system of lumbago patients showed no relation to their pulmonary function, and the rate of lipids in the body Showed a correlation with the maximum intake of oxygen but the rate of lipids in the body showed no relation to their pulmonary function.

Purpose: The pelvic tilting exercise is a well recognized rehabilitation maneuver. However, little information is available on the changes of lumbar segmental motion during pelvic tilting. This study was conducted to measure the kinematics of the pelvic tilting exercise on the supine and prone positions via fluoroscopy. Methods: A total of 10 female subjects were enrolled. During anterior, neutral, and posterior pelvic tilting, radiographs were taken in each exercise via fluoroscopy (ARCADIS Orbic, Siemens, USA). Images were sent to the picture archiving communication system (PACS), and the digitized images were analyzed using LabVIEW software (National Instruments, USA). Lumbosacral lordosis and the intervertebral body angle, intervertebral disc angle, and intervertebral displacement were analyzed. Results: The results of lumbar kinematic analysis during three tilting postures in the supine and prone positions demonstrated that lumbosacral lordosis and the intervertebral body angle and intervertebral disc angle were significantly higher when the pelvis was tilted anteriorly (p>0.05). However, there was no significant difference between anterior and neutral tilting in the intervertebral disc angle at the L3/4 level in the prone position (p>0.05), and there was no significant difference among tilting positions in intervertebral body displacement in the prone position (p>0.05). Conclusion: This study provides scientific evidence about the pelvic tilting exercise in lumbosacral segmental motion. Depending on the pelvic tilting exercise, kinematic changes were demonstrated in both positions, especially in the supine position. It is suggested that the supine position is effective for mobility, but it should be used carefully for the LBP (Low back pain) patient with hypermobility.

Purpose: Spinal instability due to weakness of abdominal muscles is one of the major causes that induces low back pain (LBP). The purpose of this study was to investigate any differences in abdominal muscle activity during curl up, roll out, and jack knife exercises using a swiss-ball or sling. Methods: Twenty healthy subjects were randomly assigned into either a swiss-ball exercise group (SBEG) or a sling exercise group (SEG). Subjects performed curl up, roll out and jack knife exercises using the swiss ball or sling. Activity of abdominal muscles (rectus abdominis and external oblique muscle) was assessed using surface EMG and normalized maximal voluntary isometric contraction (MVIC). The significance of differences between the sling exercise group and the swiss-ball exercise group was evaluated by the independent t-test. Results: These Results indicated that activities of rectus abdominis on right and left of the SEG during the curl up exercise were significantly greater than the SBEG. During the roll out exercise, activity of the abdominal muscle was not significantly different between the SEG and SBEG. In addition, during the jack knife exercise, activities of the right rectus abdominis and left external oblique muscle in the SEG were significantly greater than the SBEG. Conclusion: In conclusion, activity of the abdominal muscles was maximized when curl up and jack knife exercise were performed using the sling rather than the swiss-ball. Therefore, if increased activation of the abdominal muscle is the goal of an exercise program, curl up and jack knife exercises may be useful.

척추 불안정성은 요통과 관련되어 있다고 알려져 있다. 하지만 척추 불안정성과 관련된 임상적 연구가 충분하지 않아서 불안정성의 정의가 정량적으로 확립되어 있지 않다. 또한 추간판 퇴행 및 손상, 인대 결손, 협부 결손 등이 불안정성을 발생시키는 요인으로 알려져 있으나, 척추 불안정성에 미치는 영향이 명확하게 분석되어 있지 않다. 본 연구에서는 요추 단분절의 3 차원 유한요소 모델을 이용하여 인대 결손과 협부 결손이 단독 또는 복합적으로 척추 불안정성에 미치는 영향을 정량적으로 분석하였다. 여기서 굽힘 및 신전 시 척추의 시상각과 전위거리가 척추 불안정성을 나타내는 지표라고 가정하였다. 본 연구의 결과는 척추 불안정성의 원인과 기전을 이해하는데 도움이 될 수 있을 것이다.

Background: The flexion-relaxation phenomenon (FRP) refers to a sudden onset of activity in the erector spinae muscles that recedes or fades during full forward flexion of the trunk. Lumbar spine and hip flexion are associated with many daily physical activities that also impact trunk flexion. Shorter hamstring muscles result in a reduction of pelvic mobility that eventually culminates in low back pain (LBP). Many studies have explored the FRP in relation to LBP. However, few studies have investigated the influence of hamstring muscle length on the FRP in relation to the erector spinae muscles during trunk flexion. Objects: This study aimed to investigate the influence of hamstring muscle length on the FRP in relation to the erector spinae muscles during trunk flexion. Methods: Thirty subjects were divided into three groups according to hamstring length measured through an active knee extension test. The 30 participants consisted of 10 subjects who had a popliteal angle of 20° or less (Group 1), 10 subjects who had a popliteal angle of 21°-39° (Group 2), and 10 subjects who had a popliteal angle of 40° or more (Group 3). A one-way analysis of variance was used to compare the difference in muscle activity of the erector spinae muscles during trunk flexion. Results: The subjects with a shorter hamstring length had significantly higher muscle activity in their erector spinae muscles during trunk flexion and full trunk flexion (p < 0.05). The subjects with a shorter hamstring length also had a significantly higher flexion-relaxation ratio (p < 0.05). Conclusion: The results of this study demonstrate that differences in hamstring muscle length can influence the FRP in relation to the erector spinae muscles. This finding suggests that the shortening of the hamstring might be associated with LBP.
