PURPOSE: The purpose of this study was to determine if the program focusing on gluteal muscle exercise combined lumbar stabilization had an effects on pain, functional disability and lumbar instability in chronic low back pain patients who had lumbar instability. METHODS: Thirty four patients were recruited in this study. The participants were randomly allocated stabilization exercise group (SEG) (n=17) and gluteal muscle exercise group (GEG) (n=17). The gluteal muscle exercise group conducted gluteal muscle exercises combined lumbar stabilization and stabilization exercise group did only lumbar stabilization exercise for 30 minutes three times a week for six weeks. Pre-exercise assessment tools, visual analogue scale (VAS) and Korean version Oswestry Disability Index level (KODI) were used for pain and functional disability each. Also, these were scored by the tool of lumbar instability. The pain, functional disability levels, and lumbar instability after six weeks with this exercise were re-evaluated. RESULTS: First, SEG showed a significant decrease in the lumbar pain, functional disability levels and lumbar instability. Second, GEG showed a significant decrease in the lumbar pain, functional disability levels and lumbar instability. The third, GEG showed even more significant decrease in the lumbar pain levels, functional disability levels and lumbar instability than SEG. CONCLUSION: Gluteal muscle exercises combined lumbar stabilization are more effective than only lumbar stabilization exercise in the pain levels, functional disability levels and lumbar instability for the chronic low back pain patients with lumbar instability.

Background: Back pain is associated with a high risk of recurrence. Various physical therapy techniques for back pain have been studied, including reprogramming the central nervous system by integrating sensation and motion with sensory exercise training. Objectives: To aimed verify the effectiveness of sensorimotor training in improving postural stability and pain levels. Design: A randomized controlled trial. Methods: The study population was randomized into a sensory exercise training group and trunk stabilization training group and treated three times a week for 4 weeks. Each group took part in sensorimotor training for 15 minutes or lumbar stabilization exercise for 15 minutes. Results: After the intervention both groups showed Improvements in the variables. There was a significant difference in the dynamic postural stability, limit of stability, and modified visual analog scale scores in the sensorimotor training group compared to the lumbar stabilization exercise group (P<.05). Conclusion: Sensorimotor training appears to be an effective physical therapy exercise program that can be applied in patients with low back pain to improve muscle control ability.

Purpose: The purpose of this study was to investigate trunk and gluteal muscle activation during one-leg standing or two-leg standing with lumbar stabilizing taping using non-elastic tape. Method: The subjects of this study were twenty subjects(man=11, women=9) who be in good physical health and have not problem to back muscle and one leg standing. The surface electromyographic(EMG) data were recorded on external oblique(EO), gluteus medius(GMed), gluteus maximus(GMax), quadratus lumborum(QL) while pre- and post-lumbar stabilizing taping in two-leg standing and one-leg standing. The analysis of data was performed using the paired samples t-test to compare the difference of EMG activity of pre and post lumbar stabilizing taping. Result: Contrast of pre-lumbar stabilizing taping the muscle activity of QL in post-lumbar stabilizing taping is significant decrease on two-leg standing posture(p<.05), and the muscle activity of GMed is significant increase on one-leg standing posture(p<.05). Thus, we suggest that lumbar stabilizing taping using by functional tape will be able to affect on lumbar stability and gluteal muscle retraining.

Background: Flat-back posture refers to a posture in which the pelvis is tilted backward, the lumbar spine is bent, the upper thoracic spine is increasingly bent, and the lower thoracic spine is straight. Given that most of the day is spent sitting, we need to develop exercise programs and devices that are suitable for people who spend less time exercising than sitting. Objects: This study investigated the effects of resistance footrest exercise on spine posture angles in visual display terminal (VDT) workers with flat back. Methods: We measured the upper lumbar angle (ULA) and lower lumbar angle (LLA) using a flexible ruler for the ULA and LLA. Then, after 1 week of resistance footrest exercise designed to strengthen the lumbar spine musculature, we measured these angles again. We measured each angle three times and then compared measurements from before and after exercise. Results: There were no significant differences in the ULA following the strengthening exercise, but significant differences were observed in LLA. Conclusion: The resistance footrest exercise strengthened the muscles affecting the pelvic and lumbar lordotic angles, and increases in the LLA were changed. This suggests that the role of the lower lumbar spine in the lumbar lordotic curve is greater than that of the upper lumbar spine. In addition, considering the contemporary tendency to lead fairly sedentary lives, these results indicate that exercising while seated can be effective.

Lumbar Lordosis Angle (LLA) is an index that can be used to evaluate the curvature of the lumbar vertebrae. It can measure the structural stability of the lumbar spine and the stability of each segment of the vertebral column at the intervertebral disc angle (IDA). Especially, our data shows it is found to be a strong positive correlation between obesity and the angle of lordosis for lumbar vertebrae. Also, the reason for the large IDA in the case of obesity seems to be the result of the weakening of anatomical structure as well as the gravity effect. And, the obesity interferes with normal sagittal balance and fails to maintain a straight posture with minimal energy. Therefore, the obesity can be an important factor in causing back pain by changing the lumbar lordosis.

The concept of segmental stabilization has been one of the most exciting advancements in the field of physical therapy. Specific deep stabilizing muscle have proven to reverse motor control deficits that occurs after back injury. After an injury, a new motor programming strategy is adopted and there is excessive recruitment of the large , strong , global muscular system works instead of small segmental deep muscle recruitment for stability. Many physical therapists and doctors mistakenly prescribe therapeutic exercise for low back pain to use larger, superficial musculature to strengthen the spine for stability and pain control. But motor control coordination of local segmental muscle is actually the key to stability and pain control, not strengthening of global muscle. A recent focus in physiotherapy management of patients with chronic back pain has been the specific training of muscles surrounding the lumbar spine whose primary role is considered to be the provision of dynamic stability and segmental control to the spine. These are the deep transverse abdominis muscle and lumbar multifudus.

Purpose: The paper presents an intervention for clinical applications in the future by examining the effects of 3D stabilization exercise on patients with lumbar instability, which causes problems in the muscles and balance, and analyzing the effects of balanced lumbar muscles on the static balance. Methods: After collecting samples randomly from thirty patients with lumbar instability, fifteen patients selected for 3D stabilization exercise were placed in the stability group and fifteen patients selected for Swiss ball exercise were placed in the ball exercise group. The intervention program was applied for thirty minutes a session, once a day, three days a week for four weeks. Before the intervention, the lumbar muscle activity and static balance were measured. After four weeks, they were re-measured in the same way and the data were analyzed. Results: In relation to the within-group changes in muscle activity, all groups except for the LEO and REO groups showed significant differences. Regarding the between-group changes in muscle activity depending on the left and right difference, ES, RA, and TrA but not EO showed significant differences. In addition, there were significant differences in the between-group change in static balance. Conclusion: 3D stabilization exercise improves the muscle activity by promoting a balanced posture of lumbar muscles and changing senses, such as a proprioceptor but this had a positive influence on the static balance by controlling the balance of muscles.

PURPOSE: This study was conducted to examine the effects of motion taping on the effects of lumbar stabilization exercise. METHODS: The subjects of this study were 24 normal males with no problem in their nervous systems or musculoskeletal systems. The subjects were randomly assigned to a control group of 12 subjects and an experimental group of 12 subjects. The control group was applied with lumbar stabilization exercise while the experimental group was applied with lumbar stabilization exercise after being attached with tapes. The intervention period was four weeks in total and the subject underwent the exercises three times per week. The exercise time per session was set to one hour in principle consisting of warm-up exercise and cool-down exercise for 10 minutes each and main exercise for 40 minutes. Lumbar muscle strength was measured as a factor to examine the effects of lumbar stabilization exercises. RESULTS: The control group showed an increase in lumbar muscle strength from $111{\pm}6.30kg$ to $113{\pm}6.23kg$ and the experimental group showed an increase in lumbar muscle strength from $108{\pm}6.46kg$ to $116{\pm}5.21kg$. The increases shown by both groups were statistically significant and the experimental group that was applied with motion taping showed a larger increase in lumbar muscle strength compared to the control group. CONCLUSION: Lumbar stabilization exercise is considered to be good for lumbar stability and muscle strengthening and lumbar stabilization exercise applied with motion taping is considered to show larger effects for muscle strengthening and the improvement of lumbar functions.

The purpose of this study is to examine the activity ratios of global trunk muscles and local trunk muscles in relation to adjustments in the level of task difficulty while performing stability exercises in easily applied bridging lumbar stabilization exercise. Twenty healthy subjects performed bridging lumbar stabilization exercise while the level of task difficulty was plate was used in the same posture for all the exercises. EMG was used to examine the activity ratios of the global muscles and multifidus in relation to the level of task difficulty. Moreover, the activity ratios of the multifidus muscle, the erector spinae and the gluteus maximus muscle were measured. A one-way ANOVA with repeated measures was used, and a Bonferroni correction was conducted (${\alpha}$=.05). When the bridging lumbar stabilization exercise were performed at different difficulty levels, the activity of the multifidus muscle, which is a local muscle, was high in all three exercises. Also, compared to low intensity and intermediate intensity exercises, high intensity exercises showed more significant differences (${\alpha}$=.05). Among all the muscles, the multifidus showed the highest activity at intermediate intensity. Based on these results, we suggest that in the case of bridging lumbar stabilization exercise, low intensity or intermediate intensity exercises are more suitable and efficient for local muscle stabilization.
