To improve abdominal muscles strengthening, double straight leg lowering (DSLL) has been widely used in physical therapy, fitness program, and athletic program. The purpose of this study was to investigate the effects of the lumbar stabilization maneuver with a pressure biofeedback unit on the muscle activity of rectus abdominis (RA), external oblique (EO), and internal oblique (IO) during DSLL. Fourteen healthy young men were recruited from university population. The electromyography (EMG) activity was recorded from the RA, EO, and IO of both sides. The normalized EMG activity was compared using a paired t-test. The study showed that EMG activity in the RA, EO, and IO was significantly higher during DSLL with lumbar stabilization (DSLL-LS) compared to performed DSLL (p<.05). These results suggest that DSLL-LS is recommended as an effective method for strengthening exercise for the abdominal muscles.

Background: Walking is a complex activity. The main components of walking include balance, coordination, and symmetrical posture. The characteristics of walking patterns of stroke patients include slow walking, measured by gait cycle and walking speed. This is an important factor that reflects post-stroke quality of life and walking ability. Objective: This study aimed to examine the effect of deep lumbar muscle stabilization exercise on the spatiotemporal walking ability of stroke patients. Design: Quasi-experial study Methods: The experiment was conducted 5 times per week for 4 weeks, with 30 minutes per session, on 10 subjects in the experimental group who performed the deep lumbar muscle stabilization exercise and 10 subjects in the control group who performed a regular exercise. Variables that represent the spatiotemporal walking ability (step length, stride length, step rate, and walking speed) were measured using GAITRrite before and after the experiment and were analyzed. Results: There was a significant difference in the pre- and post-exercise spatiotemporal walking ability between the two groups (p<.05). Furthermore, there was a significant difference in the step rate and walking speed between the two groups (p<.05). Conclusions: Deep lumbar muscle stabilization exercise is effective in improving the walking ability of stroke patients. Therefore, its application will help improve the spatiotemporal walking ability of stroke patients.

Objective: The objective of this study was to investigate the effect of the thoracic mobility exercise program on pain, proprioception, and static balance ability in patients with non-specific chronic low back pain. Design: Randomized controlled trial design. Methods: Thirty patients with non-specific chronic low back pain participated in this study. The participants were randomized into the thoracic mobility exercise group (n=15) and the lumbar stabilization exercise group (n=15). Both groups received traditional physical therapy for 30 minutes per session. In addition, the thoracic mobility exercise group and the lumbar stabilization exercise group each exercise 3 times a week for 6 weeks. All participants were measured visual analog scale, proprioception test, and static balance ability before and after the intervention. Results: After 6 weeks of interventions, the thoracic mobility exercise group showed greater improvement in visual analog scale, proprioception test, and static balance ability than the LSE group (p<0.05). Further, the thoracic mobility exercise group had significant Enhancements in all measured variables compared to the baselinetest (p<0.05). However, the lumbar stabilization exercise group had significant improvement only visual analog scale, and static balance ability compared to the baselinetest (p<0.05). Conclusions: Our investigation demonstrates that the thoracic mobility exercise is an effective intervention method for improving pain, proprioception, and static balance ability in patients with non-specific chronic low back pain.

The lumbar multifidus muscle, which can be separated into deep fascicles (DM) and superficial fascicles (SM), is important for lumbar segmental stability. However, no previous studies have investigated the effect of lumbar stabilization exercises on the thickness of DM and SM. Thus, the purpose of this study was to assess DM thickness after three different lumbar segmental stabilization exercises. In total, 30 healthy male participants were recruited and randomly assigned to one of three exercise groups: hollowing in the quadruped position (H-Quad), contralateral arm and leg lift (CALL), and bilateral arm and leg lift (BALL). Each lumbar segmental stabilization exercise was conducted over 4 weeks. Ultrasonography was used to compare the DM and SM thickness before and after the 4 weeks of exercise. A mixed-model analysis of variance using Scheffe's post-hoc test was used for statistical analysis. The results showed a significant effect for the measurement time (before vs. after 4 weeks of exercise) in the DM (F=31.26, p<.05) and SM (F=4.56, p<.05). At the end of the 4 weeks, the DM thickness had increased significantly in the H-Quad exercise group, and the SM thickness had increased significantly in the CALL and BALL exercise groups. Also in the BALL exercise group, the SM thickness was greater compared with that in the H-Quad exercise group. These findings suggest that the thickness of the DM and SM were increased by different types of lumbar segmental stability exercise after 4 weeks.

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.

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 examined the effects of lumbar stabilization exercise using a Pilates reformer on the visual analog scale (VAS), Oswestry disability index (ODI), and quality of life of patients with chronic low back pain. METHODS: The study evaluated individuals aged 30 years and above who had been suffering from persistent back pain exceeding three months. The participants were allocated into two groups: an experimental cohort of 15 individuals utilizing a reformer and a control group of 15 individuals engaging in lumbar stabilization exercises on a mat without a reformer for eight weeks. Each exercise session encompassed a 10-minute warm-up, a 30-minute main exercise, and a 10-minute cool-down, totaling 50 minutes. The lumbar stabilization group using the reformer was also subjected to the same level of resistance provided by the springs. Assessments were conducted before and after the intervention using the VAS, ODI, and quality of life evaluations. RESULTS: Significant disparity existed between the experimental group utilizing the reformer and the control group before and after the intervention in terms of the VAS, ODI change, and quality of life change (p < .05). Furthermore, a significant distinction was observed in the comparison between the experimental and control groups (p < .05). CONCLUSION: Both cohorts showed a decrease in pain, a decrease in the ODI, and an improvement in the quality of life. Furthermore, the experimental group exhibited superior outcomes to the control group regarding pain reduction, reduction in the ODI, and improved quality of life.

Objective : $Dynesys^{(R)}$ is one of the pedicle-based dynamic lumbar stabilization systems and good clinical outcome has been reported. However, the cylindrical spacer between the heads of the screws undergoes deformation during assembly of the system. The pre-strain probably change the angle of instrumented spine with time and oblique-shaped spacer may reduce the pre-strain. We analyzed patients with single-level stabilization with $Dynesys^{(R)}$ and simulated oblique-shaped spacer with finite element (FE) model analysis. Methods : Consecutive 14 patients, who underwent surgery for single-level lumbar spinal stenosis and were followed-up more than 24 months (M : F=6 : 8; age, $58.7{\pm}8.0$ years), were analyzed. Lumbar lordosis and segmental angle at the index level were compared between preoperation and postoperative month 24. The von Mises stresses on the obliquely-cut spacer ($5^{\circ}$, $10^{\circ}$, $15^{\circ}$, $20^{\circ}$, $25^{\circ}$, and $30^{\circ}$) were calculated under the compressive force of 400 N and 10 Nm of moment with validated FE model of the L4-5 spinal motion segment with segmental angle of $16^{\circ}$. Results : Lumbar lordosis was not changed, while segmental angle was changed significantly from $-8.1{\pm}7.2^{\circ}$ to $-5.9{\pm}6.7^{\circ}$ (p<0.01) at postoperative month 24. The maximum von Mises stresses were markedly decreased with increased angle of the spacer up to $20^{\circ}$. The stress on the spacer was uneven with cylindrical spacer but it became even with the $15^{\circ}$ oblique spacer. Conclusion : The decreased segmental lordosis may be partially related to the pre-strain of Dynesys. Further clinical and biomechanical studies are required for relevant use of the system.
