The problem of trunk stability is a major factor in back pain.. Abdominal draw in maneuver(ADIM), One of the trunk stabilization exercises to relieve lumbar instability, is a method of inducing selective contraction of the transverse abdominis associated with anticipatory posture control among the abdominal stabilization muscles. ADIM is usually performed with a visual feedback by applying a pressure biofeedback unit(PBU) under the lumbar at the supine position, which is not functional compared to the sitting position. This study was conducted to investigate the effect of ADIM applied in supine and sitting position on 31 healthy men and women. In each posture, muscle activity was measured by rectal abdominis (RA), external oblique (EO), transverse abdominis (TrA)/internal obilique (IO) and erector spinae (ES) using wireless EMG. In the result, there was no significant difference between RA and EO between the two postures and there was a significant difference between TrA / IO and ES. In both postures, the activity of TrA/IO was higher than that of RA, and the effect of ADIM was shown to be the same, whereas TrA/IO and ES showed higher activity in sitting position. This means that the activity of the muscles involved in the postural stability and lumbar stability is increased further in the sitting position. Therefore, ADIM in sitting, which can be applied more easily in daily life, is useful for improving lumbar stability.

The purpose of this study was to investigate the effect of applying whole body vibration exercise at 30 Hz on the thickness and mechanical properties of the erector spinae. The study population included 24 adults (11 male and 13 female) in the N region. The subjects were divided into two groups, a 30Hz whole body vibration exercise(WG, n=12) and an LSG(12 subjects). Changes in the thickness and mechanical properties of the erector spinae were analyzed before the exercises and after four and eight weeks of exercises using a two-way repeated analysis of variance with a statistical significance level of α=0.05. When there was an interaction between the groups and measurement times, post hoc analyses were conducted at a statistical significance level of α=0.01. The thickness, frequency, stiffness and strain of the erector spinae muscles were significantly different in each time period and in the interaction between time period and the group (P<0.05), and recovery was significantly different only in each time period (P<0.05). Thus, 30Hz whole body vibration exercise had a positive effect on the thickness and mechanical properties of the erector spinae. The results of this preliminary study suggest that whole body vibration exercise may find a place as a lumbar stabilization exercise in clinical practice in the future.

Background: This study aimed to investigate the effects of combining the lumbar stabilization exercise with the gluteal muscle strength exercise on pain, the dysfunction index, and postnatal depression in women experiencing chronic low back pain after a cesarean section. Methods: The study used a randomized design with two groups: one group (n=15) performed the lumbar stabilization exercise along with the gluteal muscle strength exercise, while the other group (n=15) only did the lumbar stabilization exercise. The intervention consisted of 30 minute exercise sessions, twice a week, for 6 weeks. The pain was assessed using the visual analog scale (VAS), the dysfunction index with the Oswestry disability index (ODI), and postnatal depression using the edinburgh postnatal depression scale-Korean version (EPDS-K). Results: Both groups showed significant improvements in their VAS, ODI, and EPDS-K scores within their respective groups (p<.05). Additionally, the between-group analysis revealed significant differences in post-test results (p<.05). Conclusion: The combination of the lumbar stabilization exercise and the gluteal muscle strength exercise proved to be more effective in reducing pain, improving the dysfunction index, and alleviating postnatal depression in women with chronic low back pain after a cesarean section. Therefore, incorporating these exercises could be beneficial as an intervention program for women experiencing chronic low back pain after a cesarean section.

PURPOSE: This study aimed to compare the effects of pain level, lower back pain dysfunction level, psychosocial level, hip abductor strength (HAS), number of positive lumbar instability tests, and dynamic balance (DB) by applying lumbar stabilization exercises according to the presence or absence of gluteus medius muscle weakness in chronic lower back pain (CLBP) patients with lumbar instability. METHODS: Thirty-five CLBP patients with lumbar instability were divided into the gluteus medius weakness (n = 18) and gluteus medius non-weakened (n = 17) groups using the gluteus medius manual muscle test. Intervention applied conservative physical therapy and lumbar stabilization exercises to both groups that lasted three times a week for four weeks. To compare the intervention effects, the quadruple visual analog scale (QVAS), the Korean version of the Oswestry disability index (K-ODI), fear-avoidance beliefs questionnaire (FABQ), HAS, lumbar instability tests positive response counter (LIC), and DB were measured. RESULTS: Significant differences were shown for QVAS, K-ODI, FABQ, HAS, LIC, and DB for both groups pre- and post-intervention (p < .05). Compared to the gluteus medius weakness group, the gluteus medius non-weakened group showed a significant difference (p < .05) in the changes in QVAS, K-ODI, FABQ-W, FABQ-total, and HAS. CONCLUSION: In CLBP patients with lumbar instability, having gluteus medius weakness was less effective in improving lumbar stabilization exercise than gluteus medius non-weakness regarding pain level, lower back pain dysfunction level, psychosocial level excluding physical activity, and hip abductor strength. Therefore, additional gluteus medius strengthening exercises are necessary for patients with lumbar instability and gluteus medius muscle weakness.

Purpose : The purpose of this study was to investigate the effects of active release technique and lumbar stabilization exercise on pelvic asymmetry, muscle activation and pain in chronic low back pain patients. Methods : The subjects were 37 outpatients diagnosed with chronic low back pain. The patients were randomly divided into an active release technique therapy group (ART; n=18), and lumbar stabilization exercise group (LSE; n=19). These groups performed their respective therapy for a 30-minute session occurring two times a week over six-weeks period. To assess the patients' pelvic asymmetry, their pelvic tilt, and pelvic rotation was measured using X-ray imaging. EMG was used to evaluate the muscle activity of the lumbar muscle. The visual analogue scale (VAS) were used to measure the subjects' pain. Results : Both ART group, and LSE group exhibited statistically significant differences in their subjects' VAS and muscle activation of lumbar muscle after the therapy (p<.05). In ART group exhibited statistically significant decreases in their subjects' pelvic tilt and pelvic rotation after therapy (p<.05). There was a significant difference between the ART group, and LSE group (p<.05). Conclusion : The results of this study suggest that active release technique and lumbar stabilization exercise are effective in decrease pain and increase muscle activation in chronic low back pain patient. In addition active release technique is considered to be more effective in improving pelvic tilt and pelvic rotation than lumbar stabilization exercise.

Background: This study compared the effects of trunk stabilization exercise and hip joint exercises on the range of motion of the lumbar spine, pain severity, and severity of disability in patients with chronic lower back pain. Methods: A total of 30 participants were enrolled and divided into group 1 (n=10), group 2 (n=10), and group 3 (n=10) were performed by each group thrice a week for a total of 8 weeks. Group 1 performed warm-up exercise (15 min), trunk stabilization exercise (25 min), finish-up exercise (15mins). Group 2 performed warm-up exercise (15 min), hip exercise (25 mins, finish-up exercise (15mins). Group 3 warm-up exercise (15 min), trunk stabilization and hip exercise (25 min), Finish-up exercise (15 min). Participants were assessed for the range of motion of the lumbar spine, pain severity (visual analog scale score; VAS), and severity of disability (Oswestry disability index score; ODI) before and after the interventions. Results: All three groups showed a significant increase in the range of motion of the lumbar spine, but there was no significant difference among the groups. Moreover, the severity of pain and ODI were significantly decreased in all groups; however, the intergroup differences were non-significant. Conclusion: The results from this study confirmed the effectiveness of trunk stabilization and hip joint exercise in improving the lumbar range of motion, pain severity, and chronic lower back pain in patients. Thus, trunk and pelvic stabilization exercises and hip joint exercise can be used as clinical practices to treat and prevent chronic lower back pain.

Purpose : Dysmenorrhea can be caused by misalignment of the pelvis. Since pilates stabilization exercise is a methods that affects pelvic alignment by inducing contraction of abdominal muscles, the purpose of this study is to determine whether dysmenorrhea is reduced when pilates stabilization exercise is applied. Methods : 47 dysmenorrhea patients were randomly divided into experimental (n=23) and control (n=24) groups. The experimental group performed pilates stabilization exercise three times a week for 12 weeks, and the control group did not perform any intervention. Abdominal muscle thickness, lumbar pelvic alignment, and dysmenorrhea were measured before intervention, 6 weeks, and 12 weeks after intervention to determine the mean change over time and the effect of group and factor interactions (repeated measured ANOVA and contrast test for each period). Results : In the experimental group, the thickness of the transverse abdominis, internal oblique, and external oblique muscles were increased significantly by group and period (p<.05). The pelvic torsion, lordosis and dysmenorrhea were also significantly decreased by group and period. But the control group did not change significantly in any of the variables. Conclusion : Applying pilates stabilization exercise to women with dysmenorrhea may be an effective intervention that contributes to relieving dysmenorrhea by correcting the stability and alignment of the lumbar pelvis.

Purpose : The aim of this study was to investigate the change of the respiratory function of chronic low back pain patients after the thoracic manipulation and the trunk stability exercise on chronic low back pain patients. Methods : For this study, the group of the experiment was consisted of 44 patients suffering from the low back pain chronically. The participants were divided into two groups: the control group, which was assigned for core stabilization exercise (CSE), and the experimental group, which was randomly assigned for core stabilization exercise after thoracic manipulation (CSE+TM). Both groups carried out each assigned treatment on three times a week for 8 weeks. To study the change related to measurement variable from each test groups before and after intervention, paired t-test was performed. Further, the statistics for an intergroup comparison was analyzed by covariance analysis, ANCOVA. The measurement was conducted by the respiratory function, the respiratory function was measured by forced vital capacity (FVC) and forced expiratory volume in one second (FEV₁). Results : As a result, forced vital capacity (FVC) and forced expiratory volume in one second (FEV₁) showed significant differences not only by each groups but also between those groups before and after the test. Conclusion : In conclusion, both experiments, the core stabilization exercise and the core stabilization exercise conducted after thoracic manipulation, on chronic low back pain patients resulted in the significant level of difference in the respiratory function. This result indicates that the thoracic manipulation is an efficient treatment for improving the respiratory function for chronic low back pain patients.
