Purpose: This study aimed to evaluate the effects of lumbar stabilization exercise on the abdominal muscle-back muscle ratio in white-collar workers. Methods: Forty white-collar workers without any pain who worked at an information technology (IT) company located in the Gyeonggi province were included in this study. Of these, 20 subjects were randomly allocated to the lumbar stabilization exercise group, whereas the remaining 20 were randomly allocated to the control group. The lumbar stabilization exercise group performed a 40-minute-long exercise once a week for 8 weeks. The strength of the abdominal and back muscles was measured using the CENTAUR 3-D Spatial Rotation Device (BFMC, Germany). Data analysis was conducted using SPSS 18.0 for Windows. The Paired t-test was performed to compare the values measured before and after exercise within each group. The independent sample t-test was performed to analyze the differences between the 2 groups. The statistical significance for all the analyses was set at .05. Results: The strength of the abdominal muscles after the exercise significantly differed between the lumbar stabilization exercise group and the control group (p<0.05). However, the increase in the abdominal muscle-back muscle ratio was significant in only the lumbar stabilization exercise group (p<0.05), but not in the control group (p>0.05). Conclusion: The improvement of the abdominal muscle-back muscle ratio through lumbar stabilization exercise may have positive effects on lumbar stabilization. Moreover, lumbar stabilization exercise is considered beneficial for the prevention of back pain and musculoskeletal diseases.

PURPOSE: This study was to investigate the effect of stabilization exercise with abdominal breath on Balance and Oswestry Disability Index for Low Back Pain Patients. METHODS: The subjects were 18 low back pain patients in their twenties. The subjects were randomly assigned into experimental group and control group. Control group and experimental group both participated in 30 minutes of stabilization exercise for 8 weeks(5 times/week), and experimental group participated in stabilization exercise with abdominal breath. The subjects were tested balance and pain using BioRescue and Oswestry Diability Index respectively, before and after intervention. RESULTS: The experimental group showed a statistical significance in movement areas of the body's center(p<.05), but there was no significant differences between groups (p>.05). The experimental group showed a statistical significance in movement distances of the body's center with eyes open(p<.05), and there was significant differences between groups(p<.05). Both groups showed a statistical significance in ODI between pre and post test(p<.05) but there was no significant differences between groups(p>.05). CONCLUSION: As a result, the group participating in stabilization exercise with abdominal breath had a more effective improvement than the control group. Therefore, the stabilization exercise with abdominal breath may be used improving balance and pain in low back pain patients.

Purpose: This study examined the activation of the rectus abdominis (RA), external abdominal oblique (EO), transversus abdominis, internal abdominal oblique (TrA/IO), and Multifidus (MF) muscles while stabilization exercise was performed in a four-point kneeling position. Methods: Experiments were conducted on 21 healthy male adults (mean age=25.29 years) who voluntarily agreed to participate in the study. Each subject was instructed regarding maximal voluntary contractions (MVC) and stabilization exercise in four-point kneeling. While MVC and stabilization exercise of individual muscles were being performed, activation of the muscles was measured using surface electromyography (EMG). Activation of the muscles while performing stabilization exercise in four-point kneeling was normalized to a percentages of the MVC. Results: Left RA, right TrA/IO, right and left MF muscles showed significant differences among the positions. Conclusion: Selecting an optimal position can aid subjects on physical conditions while performing stabilization exercises in the four-point kneeling position.

Purpose: This study aimed to adjust the craniovertebral angle and shoulder alignment through shoulder and abdominal stabilization exercises in adults with a forward head posture. Methods: The study participants were 29 adults with a forward head posture, and they were randomly divided into the following groups: 14 participants in a combined exercise group that used shoulder and abdominal stabilization exercises and 15 participants in a shoulder exercise group that used just shoulder stabilization exercises. The participants performed the stabilization exercises for 30 minutes per day, three times a week for five weeks. Results: There were significant differences in the craniovertebral angle after intervention in the shoulder stabilization exercise group (p < 0.05). There were significant differences in the craniovertebral angle and location of the right root of the spine and both inferior angles before and after intervention in the shoulder and abdominal stabilization exercise group (p < 0.05). There was a significant difference in the location of the right root of the spine and the left inferior angle between the groups at the post-test (p < 0.05), and there was a larger change in the shoulder and abdominal stabilization exercise group. Conclusion: There was a significant difference in the craniovertebral angle and a partially significant difference in shoulder alignment before and after intervention in both groups.

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.

This study aimed to investigate the effect of the abdominal drawing-in maneuver (ADIM) and abdominal expansion maneuver (AEM) on trunk stabilization, as well as trunk muscle activities and differences in quadruple visual analogue scale, Korean Oswestry Disability Index, and Fear Avoidance Beliefs Questionnaire scores, in patients with chronic low back pain and lumbar spine instability. To increase intra-abdominal pressure during the trunk stabilization exercise, the technique of pushing the abdomen out using diaphragmatic abdominal breathing suggested by Pavel Koral was used, which we termed the AEM. Fifty patients who tested positive on more than three of the five lumbar spine instability tests were separated from 138 patients with chronic low back pain of these patients, 16 were placed in the control group (trunk stabilization exercise), 17 were placed in the ADIM group (trunk stabilization exercise with ADIM), and 17 were placed in the AEM group (trunk stabilization exercise with AEM). Each group participated in the study for 30 minutes three times weekly for 4 weeks. Surface electromyography was used to measure the trunk muscle activities during the kneeling forward and supine bridging positions, and one-way repeated analysis of variance was used to determine the statistical significance of the trunk muscle activities in the rectus abdominis, internal oblique (IO), erector spinae, and multifidus (MF) muscles. The ADIM and AEM groups showed relatively larger improvements in psychosocial and functional disability level than control group. There were significant changes among the three groups, those from the measured values of the AEM group was significantly higher than the other two groups in changes in IO and MF trunk muscle activities (p<.05). This finding demonstrates that trunk stabilization exercises with AEM is more effective than ADIM for increasing trunk deep muscle activity of chronic low back pain patients with lumbar spine instability.

Purpose : The purpose of this study is to compare the effects on abdominal muscle thickness and breathing by applying trunk strength exercise and deep stabilization exercise along with breathing exercise, which is the main respiratory muscle during breathing, to present an efficient exercise method with diaphragm breathing. Methods : This study was performed on normal 6 females and 14 males subjects. They were divided into 2 groups which trunk strength exercise and deep stabilization exercise group. The trunk strength exercise group (TSE) attended prone press-up, crunch and pelvic tiling. The deep stabilization exercise group (DSE) attended abdominal drawing, horizontal side-support and bridging exercise. Breathing exercise was performed for each set break time for 1 minute. Results : First, in the comparison of the change in the thickness of the abdominal muscle between the trunk strength training group and the deep stabilization group before and after exercise, there was a statistically significant difference in the comparison of transverse abdominis (TrA), rectus femoris (RF), external oblique (EO), internal oblique (IO) (p<.05). However, there was no significant difference in any comparison between groups (p>.05). Second, in the comparison of changes in respiratory function between the trunk strength exercise group and the deep stabilization exercise group before and after exercise, there were statistically significant differences in the exerted forced vital capacity (FVC), forced expiratory volume at one second (FEV₁), peak expiratory flow (PEF) in the comparison before and after the experiment (p<.05). However, there was no significant difference in any comparison between groups (p>.05). Conclusion : As a result of this study, it can be said that both trunk strength exercises and deep stabilization exercises along with diaphragm breathing are exercises that strengthen deep and superficial muscles, and have a positive effect on breathing function as well as muscle strength. However, it is not known which exercise was more effective, and because it was combined with breathing exercise, the interference effect appeared.

Purpose: The purpose of this study was to examine the effects of the PNF stabilization technique for the hip joint and the bridging exercise on the trunk stabilizer muscles in healthy adults. Methods: Twenty-eight healthy adults were randomly allocated to either a PNF stabilization exercise group (n = 12) or a bridging exercise group (n = 16). The outcome measures included the contraction thickness ratio in the transversus abdominis (TrA), internal oblique (IO), and external oblique (EO), and the TrA lateral slide was assessed during the abdominal drawing-in maneuver using b-mode ultrasound. The researcher measured the abdominal muscle thickness of each participant before the therapist began the intervention and at the moment that the intervention was applied. Between-group comparisons were performed using the Mann-Whitney U test. The level of statistical significance was set at 0.05. Results: The PNF intervention program showed a significant increase in the trunk stabilizer muscle. The percentage of change in the TrA thickness showed a significant interaction between intervention. However, there were no significant differences in the IO and EO between the two groups. Conclusion: The PNF stabilization technique for the hip joint can be used effectively to improve the IO and TrA muscles in healthy adults.
