Many pregnant women have experienced low back pain (LBP) during pregnancy and after delivery, and it has been an important component in women health. This study was designed to investigate the characteristics and management of the LBP in postpartum women. Eighty-five postpartum women were participated in this survey. Mean age of 85 women was 28.1 years. Of 85 postpartum women, 55.3% (n=47) had LBP after pregnancy. Thirty of 47 women had pain on lumbar region, 17 postpartum women had pain on sacroilium region. Of 85 postpartum women, 74% (n=54) had LBP before pregnancy and 71.8% (n=61) had LBP during pregnancy. Of 47 postpartum women who had LBP, 83% (n=39) had not received medical management for LBP, 12.8% (n=6) took medication, and 4.3% (n=2) performed self-exercise. None of postpartum women had received physical therapy during pregnancy and after delivery for treatment low back pain. The pain in SI region was more severe than in lumbar region after pregnancy according to VAS (visual analog scale) (p<.05). However, there was no significant difference in VAS scores between SI pain and lumbar pain before and during pregnancy (p>.05). Pain region after delivery was related to pain region of pre-pregnancy and during pregnancy (p<.01). Pain level after delivery was related to the pain and night pain level during pregnancy (p<.01).

Low back pain (LBP) is a significant in today's society, with lifetime include factors associated with LBP ar reporter. Among the causes, aberration of posture may play a role in the development of LBP. Many investigators have assessed the curvature of spine in standing posture. But LBP is associated with Lumber Hyperlordosis of Hyperlordosis is controversial Subjects: In conservative treatment(acupuncture, herb med, manipulation & TENS. exercise, potural correction) for a 40 years old woman who had low back pain(V AS) be caused by decrease lumbar lordotic angie. Objectives: The object is change of lumbar lordotic angle of a 40 years old woman who had low back pain with Lumbar hyperlordosis, In conservative treatment. Method: In conservative treatment, We added taping therapy(mechanical correction taping of Kinesio Taping) about Lumbar Lordosis. Conclusion: We experienced a 40 years old woman who had love pack pain with Lumbar hyperlordosis. In conservative treatment, Her pain was Improved by additional taping therapy In company with decrease of Lumbar Lordosis. 1. abnormal spinal curvature, specially lumbar hyperlordosis act on induction & perpetuation agent for low back pain 2. In a patient had low back pain with lumbar hyperlordosis, change of lumbar lordotic angle is of utility value for the effect of treatment and assessment of prognosis. 3. pain control is more relative with change of lumbosacral angle than lumbar lordotic angle, in patient had low back pain with lumbar hyperlordosis. 4. mechanical taping therapy with elastic adhesive tape is effective for patient had low back pain with lumbar hyperlordosis

Objectives: This study was designed to investigate the correlation between cervical, lumbar lordosis and low back pain(LBP), sex, age and duration of LBP. Methods : Cervical, lumbar lordosis(by Cobb's Method) and Ferguson's angle were measured and evaluated in LBP group and control. Radiograph was taken in lateral direction, erect position. Cobb's angle between C1-C7, C2-C7, L1-L5, L1-S1 and Ferguson's angle were measured and investigated with statistical program. Results: 1. Cervical lordosis have no relation to LBP, sex and age. 2. Lumbar lordosis and Ferguson's angle have no relation to LBP and sex. 3. Cobb's angle L1-L5 have no relation to age. Lumbar lordosis from L1 to S1(Cobb's angle L1-S1) increased in old group(Age>40) compared to young group(Age${\leq}$40). 4. In LBP group, Cobb's angle L1-S1 have no relation to duration of LBP. Lumbar lordosis from L1 to L5(Cobb's angle L1-L5) decreased in acute LBP group compared to Chronic group. Conclusions : Cervical, lumbar lordosis and Ferguson's angle have no relation to LBP and sex. As far as age is concerned, old group have larger lumbosacral lordosis than young group. Acute LBP group have smaller lumbar lordosis(Cobb's angle L1-L5) than chronic group.

Objective: Low back pain (LBP) is a symptom that accounts for a large proportion of musculoskeletal pain. Among them, non-specific LBP (NSLBP) means that the pathological cause is unknown, and belongs to the most common LBP. Studies on the mechanism of muscle control in LBP are insufficient, and quantitative studies are needed. Design: Observational cross-sectional study design Methods: A Thirty participants with NSLBP symptoms were enrolled, and their pressure pain thresholds (PPT) and muscle and fat thickness were measured. Participants measured the paraspinal muscles (PM) of the thoracic and lumbar spine and medial hamstring (semitendinosus) on the dominant and non-dominant sides in the prone position. Results: Among the variables that were significant in the correlation analysis, PM of the thoracic and lumbar spine showed a significant relationship in the PPT ([thoracic spine PM]=1.141+0.912 [lumbar spine PM]). Also, there was a significant relationship between the lumbar spine PM in the PPT and the thoracic spine PM in the muscle thickness ([lumbar spine PM of PPT]=4.057+0.117 [thoracic spine PM of muscle thickness]) Conclusions: Although there was no muscle imbalance according to the dominant and non-dominant side, there is a correlation between the pressure pain threshold and the muscle thickness between the paraspinal muscles of the thoracic spine and the lumbar spine.

Objectives : This study was performed in order to investigate the relation of body composition analysis and radiological parameter(lumbosacral angle, lumbar lordortic angle, lumbar gravity line). Methods : This study was carried out with the data from comprehensive medical testing. 75 subject aged 20-59 performed the segmental bioelectrical impedance analysis, questionnaire. And lumbosacral angle, lumbar lordortic angle and lumbar gravity line were measured in the standing position x-ray. Then we analyzed the data. Results : Low back pain(LBP) prevalence in high obesity index(Body Mass Index(BMI), Percentage of Body Fat(PBF), Waist Hip Ratio(WHR)) group was higher than LBP prevalence in normal obesity index group(p<0.01). In LBP group, lumbosacral angle, lumbar lordortic angle were significantly lager than Non-LBP group(p<0.001). And 75% of LBP group indicated abnormal lumbar gravity line ratio(0.67 < Normal lumbar gravity line ratio <1.00). When it comes to analyze relation between obesity index and radiological parameter, no-significant change was seen. Conclusions : This study carried as following research after the study on relation of obesity, LBP and trunk muscle strength. Results from this investigation showed positive correlation between obesity and LBP prevalence. But obesity index didn't indicate significant correlation with structural changes of lumbar vertebrae. When considering prior research, trunk muscle strength changes were more related to LBP prevelence in obese people. This results are expected to explain causes of LBP in obese group.

Objectives : In the assessment of the lumbar spine by magnetic resonance imaging (hereinafter, "MRI"), changes in the paraspinal muscles are overlooked. The purpose of our study is to examine the correlation between the multifidus muscle atrophy on MRI findings and the clinical findings in low back pain (hereinafter, "LBP") patients. Methods : The retrospective study on 38 LBP patients, presenting either with or without associated leg pains, was undertaken. The MRI findings on the patients were visually analysed to find out a lumbar multifidus muscle atrophy, disc herniation, disc degeneration, spinal stenosis and nerve root compressions. The clinical history in each case was obtained from their case notes and pain drawing charts. Results : The lumbar multifidus muscle atrophy has occurred from more than 80% of the patients with LBP. Most of lumbar multifidus muscle atrophies have increased from lower level of lumbar spine. It was bilateral in the majority of the cases. In addition, multifidus muscle atrophy was correlated to the patient's age, disc degenerations and spinal stenosis. On the contrary, gender, the duration of LBP, referred leg pain, disc herniation and nerve root compressions had no relevance to multifidus muscle atrophies. Therefore, when assessing the MRIs of the lumbar spine, we should have more attetion on multifidus muscle, because it has lot's of information about spinal neuropathy problems. Conclusions : Therefore, the examination of multifidus muscle atrophies should be considered when assessing the MRIs of the lumbar spine. In addition, it helps to evaluate and plan the treatment modalities of LBP. Moreover, it prevents from LBP by discovering the importance between the multifidus muscle and the spine stabilization exercise.

The purpose of this study was to compare the onset times of muscle activities and the order of muscle firing in hamstring gluteus maximus, and lumbar erector spinae muscle during active hip extension between subjects with low back pain (LBP) and healthy subjects. Thirty subjects, 15 with LBP and 15 healthy subjects, participated in this study. Electromyographic activity was recorded during active hip extension in prone and standing position. Relative onset times of these muscle activities were determined. Similar muscle firing order in hamstring, gluteus maximus, and lumbar erector spinae muscle showed in both groups and positions. However, the onset time of gluteus maximus was significantly later in prone and standing active hip extension in subjects with LBP than in healthy subjects. The onset time of lumber erector spinae muscle activity was significantly delayed in subjects with LBP in standing active hip extension, The delayed onset times of gluteus maximus and lumbar erector spinae muscles' activities were probably related to LBP. Further studies are needed to identify whether the delayed onset times of gluteus maximus and lumbar erector spinae muscle activities are the contributing factors to LBP.

Background: We developed a novel integrative lumbar stabilization technique that combines lumbar extension (LE) exercise with abdominal drawing-in maneuver (ADIM) to ameliorate low back pain (LBP) associated with neuromuscular imbalance and instability, based on the collective evidence of contemporary spinal rehabilitation. Objects: The specific aim of the present study was to investigate the effects of LE exercise with and without ADIM on core muscle strength, lumbar spinal instability, and pain, as well as functional characteristics in individuals with LBP using advanced radiographic imaging techniques. Methods: patients with mechanical LBP (N = 40, 6 males; $35.1{\pm}7.6years$) were recruited and randomly assigned either to the combined LE and ADIM (experimental group) or the LE alone (control group). Outcome measures included the visual analog scale, the modified Oswestry Disability Index, muscle strength imbalance (MSI), and radiographic imaging. The lumbar intervertebral displacement (LID), intervertebral (IV) and total lumbar extension (TLE) angles were calculated to evaluate the lumbar segmental instability. Results: The experimental group showed significant differences in the L3-L4, L5-S1 LIDs, L4-L5 and L5-S1 IV angles, and TLE angle as compared to the controls (p<.05). Immediate pain reduction and muscle strength imbalance ratio were significantly different between the groups (p<.05). Conclusion: These results suggest that the addition of ADIM significantly increased lumbar spinal stabilization in individuals with LBP, thereby reducing pain associated with functional lumbar flexion during daily activities.

Objectives: This study explored the relationships between Bone Mineral Density (BMD), Body Mass Index(BMI), Age, pain duration outcomes of treatment for Low Back Pain(LBP) in 3 groups(normal,osteopenia,osteoporosis) of female patients. Methods: We evaluated 32 cases of normal, 30 cases of osteopenia and 38 cases of osteoporosis based on BMD, BMI, Age, pain duration among the female inpatients with LBP caused by lumbar disc herniation, admitted at Jaseng Hospital of Oriental Medicine from January 2010 to December 2011. And we measured VNRS(Verbal Numeric Rating Scale) to evaluate the conservative treatment effects. Results: In improvement of female LBP caused by lumbar disc herniation, BMD(T-score), BMI had not proved correlation(P-value>0.05). Female patients' age was negatively correlated with T-score. In pain improvement, BMD normal group showed more reduction of NRS(numeric rating scale) than osteoporosis group, but that had not proved correlation(p-value=0.893). Conclusions: Statically, among the female inpatients with LBP caused by lumbar disc herniation, had no significant differences between the normal group, osteopenia group and osteoporosis group's improvement rate, depending on treating period.

To investigate the risk factors of low back pain, an epidemiological study was carried out among male workers aged 20-55 employed in an automobile industry in Korea during the time period from February 1993 to October 1995. Workers participated to this study were divided into low back pain group(LBP) and control group, according to the self-reports by written questionnaires. General characteristics, medical history, work related factors, fatigue, and MMPI were compared between two groups. To clarify the relationship between job related low back pain and radiologic features of lumbar spine, radiographic study was carried out. The resultant data were processed for $x^2-test$, t-test, and stepwise logistic regression to confirm the adjusted odds ratios. The results were as follows: 1. History of back disease, lifting and carrying work, excessive physical fatigue, and weakend back strength of individual workers were directly associated with low back pain. Odd ratios of these 4 risk factors of low back pain were 5.07, 3.34, 1.49, and 1.22 respectively. 2. The frequency of low back pain history was significantly higher in LBP group. 3. Back muscle strength of lumbar spine of LBP group were significantly lower than control group. 4. The workers in LBP group revealed high fatigue symptoms. 5. In MMPI test LBP group showed higher scales in hypochondriasis, depression, hysteria, psychopathic deviate, paranoia, psychasthenia, schizophrenia, and hypomania. 6. LBP group were more frequently involved in lifting and carrying, working in awkward position, bending, twisting and using lower extremities. 7. LBP group were exposed more to vibration during working. 8. In the Analysis of radiographs of lumbar spine, Jacob's line not crossing fourth lumhar disc space, transitional vertebrae and lumbar displacement more than 4.4mm in standing lateral view were more frequently observed in LBP group than control group. Through these results, it is concluded that identification of previous history of back problem, change of work or working environment for workers with previous back problem and measures to relieve both physical and psychological fatigue of the workers are required for optimal management of work-related back problems among workers. In the present study, several results were different from the previous reports: Jacob's line not corssing fourth lumbar disc space, lumbarization, and vertebral slipping (spondylolisthesis) more than 4.4mm are related to backache. Meticulous studies are required to elucidate the difference.
