Purpose: This study examined the characteristics of gait in patients with chronic low back pain. Methods: The subjects were out-patients suffering from chronic low back pain at the department of physical therapy, B hospital in Seoul. Gait analysis was performed by dividing the subjects into two groups. The study and control group comprised 15 chronic low back pain patients and 14 healthy people, respectively. Gait analysis was performed using a VICON 512 Motion Analysis System to obtain the spatio-temporal and kinematic parameters. Results: First, there was a significant difference in the spatio-temporal parameters between the two groups (p<0.05). Second, the study group showed significant differences in the kinematic parameters during the stance phase (p<0.05). Third, there were significant differences in kinematic parameters in the study group during the swing phase (p<0.05). Conclusion: The gait pattern of patients with chronic low back pain is characterized by more rigid patterns. Compared to the control group, there was a decrease in the spatio-temporal parameters and kinematic parameters in patients with chronic low back pain. These findings are expected to play a role as basic data and to form a rehabilitation program for low back pain patients.

Purpose: This study examined whether a single application of a lumbar flexion muscle energy technique (MET) could significantly influence pain, functional status, and range of motion in chronic back pain patients with restricted active trunk flexion. Methods: Twenty volunteers were randomly assigned to either a control group or an experimental group. Ten subjects in the control group received no treatment. Ten subjects in the experimental group received five sessions with the muscle energy technique, five times per week for two weeks. Outcomes were measured before and after two weeks of treatment in both groups. Pain intensity was assessed using a visual analogue scale (VAS). Range of motion was measured using the sit-and-reach test (SRT). Functional disability levels were assessed using the Korean version of the Oswestry Disability Index (KODI). Results: The experimental group showed a significant difference in VAS, KODI, and SRT between pre- and post-treatment (p < .05), while the control group showed no significant changes. The changes in VAS, ODI, and SRT were statistically significant between the groups pre- and post-treatment (p < .05). Conclusion: This muscle energy technique is clinically effective for chronic low back pain patients.

Purpose: The purpose of the study was to compare the effects of different methods of pelvic control on abdominal muscle activity and lumbopelvic rotation angle during active straight leg raising (ASLR) in patients with chronic back pain. Methods: The study participants were patients with low back pain (n = 30). They were instructed to perform ASLR with pelvic control, ASLR with pelvic belt, and ASLR only. Surface electromyography data were collected from the ipsilateral rectus femoris (IRF), ipsilateral internal oblique (IIO), contralateral external oblique (CEO), and ipsilateral rectus abdominal (IRA) muscles, and lumbopelvic rotation angle was measured using a motion analysis device. Results: Activation of all abdominal muscles was greater in the ASLR with pelvic control group than in the ASLR with pelvic belt and ASLR groups. The lumbopelvic rotation angle was lower in the ASLR with pelvic control group than in the other two groups (p < 0.05). Conclusion: These results suggest that ALSR with pelvic control is an effective means of increasing abdominal muscle activity and reducing unwanted lumbopelvic rotation in patients with chronic low back pain. Controlling the pelvis using the opposite leg is an effective form of ASLR exercise for patients with chronic low back pain.

The purpose of this study were analysed fatigue character of lumbar extension Muscle during repeated trunk flexion-extension motion we used EMG multi-telemeter (WEB 5000, Nihon Koden, Japan), Medex lumbar extension machine(Ocala, USA). We evaluated 20 persons on chronic low back pain group and 20 persons on control group. We analysed the quantitative variables IMF, MF, decreased ratios of MF to investigate fatigue. As a result, the following conclusion was drawn : 1. Each lumbar IMF of CLBP was L5> L3> L1 in the order of their size. CON group was similar quantitative and same order. But the relationship of two groups were not significantly. 2 The IMF within lumbar position(L1-L3, L1-L5, L3-L5) of two groups was significantly all positions(p<.05). 3. The MF shifting at lumbar position of two groups during repeated trunk flexion-extension motion was decrease shifting pattern with increase repeating motion, especially CLBP group was suddenly dropping than CON at all lumbar positions(L1, L3, L5) on early stage motion(34 set). 4. The lumbar fatigue of CLBP was higher than CON during repeated trunk flexion-extention motion, so CLBP supposed more tired than CON. And it was significantly within two groups at lumbar positions(L1, L3 : p<.05, L5 : P<.01).

Background: The purpose of this study was to identify the effects of the abdominal drawing-in maneuver (ADIM) for contraction training of transversus abdominis (TrA) to the patient with chronic low back pain (CLBP). Methods: A 37-year female patient with CLBP participated in study. This study was fix to method of ADIM that maintain to draw in lower abdomen in sitting position on chair and fix 1 time protocol that perform rest for 1-min and ADIM for 1-min during 10-min. Hereunder the subject performed 2 times protocol during 30-min. Measurement method were visual analogue scale (VAS), Korean version of Oswestry disability index (KODI) and using ultrasound imaging. Results: VAS was decreased 5cm to 1cm after intervention 3 weeks, KODI was decreased 22% to 9% after intervention 3 weeks and changes in thickness of the TrA were increased 32% to 68% during ADIM. Conclusions: These findings suggest that performed the ADIM took effect for decreased pain and functional disability level with increased changes in thickness of the TrA. Therefore, patients with CLBP should be use for training of deep abdominal muscles apply to the ADIM.

The Purpose of this study was to investigate the change of lumbar extensor strength according to lumbosacral angle on chronic lumbar back pain patients. For this investigation lumbar extensor strength was administered to 60 patients who were diagnosed chronic lumbar back pain The subjects was to investigate lumbosacral angle in standing position and it were calculated lumbar extensor strength by using Medex. The result of this study summarized are as follows ; 1. Total experimental group exhibited significantly higher difference than control group in lumbar extensor strength among all degree lumbosacral angle. 2. In the relationship between experimental group and control group in lumbar extensor strength among lumbosacral angle, all degree difference was revealed II, I, III order. 3. In the relationship between experimental group and control group in lumbar extensor strength among lumbosacral angle, I group difference was did not. 4. In the relationship between experimental group and control group in lumbar extensor strength among lumbosacral angle, all degree among II group was noted significantly difference except 24, 72 angle. 5. In the relationship between experimental group and control group in lumbar extensor strength among lumbosacral angle, control group was revealed higher muscle strength 48, 60, 72 angle, however no significantly difference was noted 0, 12, 24 angle. The study was objected difference of other group in both of experimental and control group. Because lumbar extensor weakness with bad position was gradually increased back pain, to Maintain normal lumbosacral angle befor exercising lumbar extensor strength was most important.

Study Design: Case report. Objectives: We report 3 cases of loss of disc height after spontaneous regression of a herniated lumbar disc. Summary of Literature Review: Reports of spontaneous regression of a herniated lumbar disc were identified. Materials and Methods: We conservatively treated 3 patients who were diagnosed with a herniated lumbar disc. During outpatient follow-up, radiating pain improved in all patients, but they complained of chronic lower back pain. Magnetic resonance imaging (MRI) was performed for diagnostic purposes. Results: On MRI, spontaneous regression of the herniated lumbar discs was observed, but loss of disc height was also found. Conclusions: A herniated lumbar disc may be a risk factor for loss of disc height. It is important to recognize that a patient with a herniated lumbar disc can struggle with chronic lower back pain even if spontaneous regression of the herniated lumbar disc occurs.
