The purposes of this study were to assess and modify the original classification categories of the modified Oswestry Low Back Pain Disability Questionnaire (ODQ) and to determine the unidimensionality of the modified ODQ applying Rasch Analysis. The data were obtained from 108 work-related low back pain patients by physical therapists. Construct validity of the scale using the Rasch model required the structure of the rating scale to be modified from 6 response levels to 4 response levels. Eight items from the modified ODQ fit the Rasch model. The items, "pain intensity" and "social life" showed misfit statistics. In general, the order of item difficulty of the remaining 8 items showed a logical item difficulty hierarchy with the "changing degree of pain" item being the most difficult and the "walk" item being the easiest. The results showed that further study is needed to expand the construct of ODQ including additional higher-level items related to work activities. This study may be useful for establishing a standard method to assess the functionality of low back pain patients.

Objective : There were few reports about statistically significant factor which contribute to low back pain[LBP] after microscopic discectomy. We analyzed the result of percutaneous radiofrequency neurotomy[PRN] for low back pain after microscopic discectomy in lumbar disc herniation. Methods : Forty four patients with LBP after microscopic discectomy who were treated by one level microscopic discectomy from January 2003 to March 2004 were included in this study. They were divided into two groups by the presence of preoperative LBP into preoperative back pain group [group I] and postoperative back pain group [group II]. Radiofrequency procedures were performed in the usual manner, targetting the medial branch of L4, L5 and Sl. Pain relief was estimated at 1 week, 1 month and 6 months following the procedure, using the visual analogue scale. Above 50% pain relief was defined as the positive response. Results : Positive responders were 16 patients [73%] at 1 week, 12 patients [55%] at 1 month, and 7 patients [32%] at 6 months after PRN in group I. In Group II, 18 patients, 15 patients and 13 patients responded positively after 1 week, 1 month and 6 months after PRN, respectively. Conclusion : PRN is an effective treatment for newly developed low back pain after microscopic discectomy. There was no morbidity in our series, but long-term follow up is necessary.

This case study reports the clinical response to Korean Medicine (KM) treatments including capsaicin-containing (CP) pharmacopuncture in three patients with acute low back and hip pain. Three patients were diagnosed with acute lumbar sprain, and were treated with CP pharmacopuncture, and other KM treatments including acupuncture, cupping, and herbal medicine. Numeric Rating Scale (NRS), Oswestry Disablility Index (ODI), and Clinical Evaluation Grade (CEG) were used to evaluate symptom changes. After one or two treatments, acute pain with limited range of motion in the low back and thigh region improved with a decrease in NRS, ODI, and CEG. These results suggest that further studies on KM treatments including CP pharmacopuncture for acute low back and hip pain are warranted.

The date had been acquisited through the questionaires of those and analysed in Korea Institute of Maritime and Fisheries Technology from February 10 to April 10 in 1999. The results of this study are as follows: 1. The incidence of Occupational low back pain for the recent 12 months has been recorded as 56.2% of the subject. 2. The highter Occupational satisfaction has the lower incidence of low back pain(p＜0.01). and the person who takes a rest(p＜0.05) and physical exercise regularly(p＜0.01) has lower experience of the incidence. 3. The incidence of low back pain by charateristics of vessel was turn out as 59.3% of the fishing vessel, 55.3% merchantmarine and 52.9% of the vessel of special purpose. The incidence of each department of a ship has recorded as 54.3% of Deck Dept. 59.2% of engine Dept but there was little relationship between those. And the longer period of work and on-board service has the hither incidence of the higher incdence(p＜0.01). 4. The fittness of the working table (p＜0.01) and chair(p＜0.01) has affeced the incidence of low back pain significantly 5. The higher incidence of low back pain has been experienced in case of working: in back posture, and lifting up or carrying a heavy load(p＜0.01) 6. The major cause of low back pain was turned out as excessive workload(26.5%) and stress (18.5%) ; the stress(24.1%) and excessive overwork(22.4%) for Deck dept. and excessive workload(32.3%) and bad position(21.7%) for Engine Dept(P＜0.01)

Background: The purpose of this study was to systematic review the effect of exercise programs for chronic low back pain patients. We needs systematic development of low back pain exercise program to reduce economic cost further doing great service to public health promotion. Methods: We searched to the effects of exercise programs for chronic low back pain patients by Dankook University electronic library databases of DBPIA, KSI KISS, CINAHL, MEDLINE and PEDro combined with a hand search of papers published in relevant journals. Any type of study relevant to the topic published during time period from 1970 to 2007 was included. Results: The literature search identified 30 studies. 1.Performing the flexion exercise increased abdominal muscle activity but acute herniated intervertebral disc should be avoided. 2.The general lumbar extension exercise used lumbar extension machine and the muscle power increases, significant probability the change. 3.The spinal segments exercise for the patients offered significant efficacy and appeared to be a reasonable therapeutic option. 4.Spinal stabilization exercises appear to improve trunk endurance and balance to patients with chronic low back pain. This exercise programs had effective decrease pain and disability. Conclusion: The review suggests that although the exercise programs for chronic low back pain patients, and we expected the efficacy of the exercise programs for chronic low back pain patients used in this study should be further investigated in a long period study and objective outcomes.

Objective: We have various ways in evaluating the level of low back pain as sequelae, general approaches such as neurologic examination, MRI, Radiologic examination and evaluating the effect of psychological stress on the low back pain. Besides We can find another approach to evaluating the sequale of low back pain in TA patients. So, I intend to analyze how much relationship the patients that got low back pain by TA have with Roland Morris Disability Scale(RMS) in 2 months after discharge. Methods: In this article, I will compare two results of TA inpatients and non-TA inpatients, which obtained with the RMS. This study was carried out about 22 TA patients and 18 non-TA patients, who had low back pain and were hospitalized between March 2002 and July 2002. Results & conclusions : 1. RMS point is related with the post-discharge term to a point of time of answering the questionnaire in both TA patients and non-TA patients. 2. In distribution of RMS point, Gr II take most possesion as 41% in TA patients while Gr I take most possesion as 56% in non-TA patients. 3. In distribution of RMS point, patients that correspond to more than Gr III take 27% in TA patients, 16% in non-TA patients. 4. TA patients show higher level of distribution than non-TA patients in RMS point in verifying them by mean value and T-test. 5. Degree of pain score change(${\Delta}$P.S), using mean value and T-test, showed lower level of distribution in TA patients than non-TA patients. 6. We can see that TA patients have more restriction in their life for low back pain.

Purpose: The purpose of this study was to examine the effects of spinal decompression therapy on pain and disability in patients with chronic low back pain. Methods: Twenty patients with chronic low back pain were divided into an experimental group (spinal decompression therapy, n=10) and a control group (conservative physical therapy, n=10). Both groups were treated three times a week over a four-week period. Results: The comparison of between-group changes post-treatment revealed statistically significant lower levels of pain and disability in the experimental group than the control group. The comparison of within each group changes before and after the treatment showed statistically significant declines in pain and disability indexes of both groups. Conclusion: Spinal decompression therapy may be an effective intervention for improving pain and disability in patients with chronic low back pain.

Objective: The purpose of this study was to compare the hip joint muscle strength of patients with chronic back pain with lumbar instability and normal subjects. Design: A case control study. Methods: Five types of lumbar instability test were conducted on forty young women with chronic low back pain for more than six months, and those who had 3 or more positive tests were selected as subjects. To select chronic back pain patients with lumbar instability group, aberrant movement patterns during lumbar flexion test (FMT), prone instability test (PIT), posterior-anterior mobility test (PAT), passive lumbar extension test (PLE), and pressure bio-feedback (PBF) were applied. In addition, a digital muscle strength meter was used to measure the hip flexor, extensor, adductor, and abductor muscles of chronic low back pain patients with lumbar instability group (n=20) and normal subject group (n=20). Results: As a result of comparing the hip joint muscle strength between the chronic back pain patient group with lumbar instability and the normal group, there were significant differences in the hip extensor, abductor, and adductor muscles (p<0.05). Conclusions: Patients of chronic back pain with lumbar instability were found to have weak hip joint muscle strength. Therefore, this study suggest that include hip joint strength exercise for functional recovery of chronic back pain patients.

Objective: The purpose of this study is to compare chronic low back pain patients' pain provocation position so as to identify the relevance with lumbar stabilizing muscles atrophy and pain provocation position. Design: Cross-sectional study. Methods: Fifty five chronic low back pain patients were participated in this study. Subjects were eligible for study participation if they were 35-55 years old and had experienced low back pain for more than 3 months. Subjects were questioned about pain and pain provocation test were done. And then they were inspected their cross sectional area (CSA) of lumbar muscles (erector spinae, iliopsoas, and multifidus) by using computed tomography. Analyze the relevance through the result data with painful area, aspect of pain and pain provocation position. Results: CSA of erector spinae showed significant decrease on ipsilateral extension position (p<0.05). Iliopsoas muscle showed significant decrease on contralateral position (p<0.05). Multifidus showed significant decrease on the position of contralateral extension and contralateral flexion (p<0.05). Conclusions: Based on the results of our study, it may be possible to evaluate muscle atrophy by assessing causing position.
