Objective: The aim of this study was to investigate effect of core stabilization exercises on the erector spinae contractile properties and trunk isokinetic muscle function of middle age with low physical activity and sedentary lifestyle. Method: Twenty (female: n=10, male: n=10) middle-age subjects (age: 37.25 ± 6.08 years, height: 168.01 ± 6.84 cm, weight: 71.37 ± 11.75 kg) participated in this study. Tensiomyography was measured on the erector spinae, and the isokinetic trunk muscle function test was measured at an angular velocity of 60 °/s and 90 °/s. All subjects performed the core stabilization exercises for 60 min per day, 3 times a week, for 7 weeks. A paired t-test was performed with a significance level of 0.05. Results: Tensiomyography of the erector spinae revealed a significant post-exercise increase in the maximum radial displacement (p < .05) and velocity of contraction (p < .05), however, there wasn't a significant post-exercise change in the contraction time. Additionally, the isokinetic muscle function test of the trunk revealed a significant post-exercise increase in trunk extensor relative strength (p < .05) and strength ratio (p < .05). Conclusion: Our results indicated that core stabilization exercises reduced erector spinae muscle stiffness, increased the velocity of erector spinae contraction. Additionally, data showed the improvement in the trunk extensor strength help induce a more balanced development in trunk muscle.

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: The purpose of this study was to evaluate the effect of a trunk stabilization exercise program on the participants' scoliosis angle, pulmonary function, and growth hormones. Method: In the study, 30 participants were divided into a normal scoliosis exercise group (n=15) and an obese scoliosis exercise group (n=15). The participants performed a trunk stabilization exercise program three times a week for 12 weeks, and the exercise sessions lasted 50 minutes. The participants' pulmonary function [FVC, FEV1, FEV1/FVC, and PEF] was measured using a CardioTouch 3000S, and their scoliosis angles were measured using the Cobb's angle. The levels of growth hormone (GH) and insulin-like growth factor-1 (IGF-1) were analyzed on an immunoradiometric assay (IRMA) and radioimmunoassay (RIA), respectively. Results: After the intervention, the scoliosis angle, hormone levels, and pulmonary function increased significantly in both groups (p<.05). The result of the intergroup difference test indicated statistically significant differences in the three items (scoliosis angle, hormone levels, and pulmonary function) between the two groups (p<.05). Conclusion: Therefore, this program may be recommended as a therapeutic intervention for patients with scoliosis.

The aim of this study is to compare measurements of abdominal muscle thickness using ultrasonography imaging (USI) to those using a special transducer head device, during five different trunk stabilization exercises, ultimately to determine which exercise led to the greatest muscle thickness. Thirty eight healthy subjects participated in this cross-sectional study. The five types of trunk stabilization - i.e., a sit-up on the supine, an upper and lower extremity raise with quadruped on the prone, a leg raise in sitting on the ball, trunk rolling on the ball, and balance using sling on the prone position - were each performed with an abdominal draw. The thickness of the abdominal muscle - including the transverse abdominal (TrA), internal oblique (IO), and external oblique (EO) - was measured by USI with a special transducer head device, at rest and then at contraction in each position. Data were analyzed using one-way repeated ANOVA with the level of significance set at ${\alpha}$=.05. The results were as follows: 1) the TrA thickness was statistically significant (p<.05), whereas the IO and EO thicknesses were not (p>.05); 2) among the five types of trunk stabilization, TrA thickness significantly increased with the balance using a sling in the prone position, (p<.05), whereas no significant difference was noted for the four types of trunk stabilization (p>.05); 3) reliability data showed that there was a high degree of consistency among the measurements taken using the special transducer head device (ICC=.92). In conclusion, the balance using a sling in the prone position was more effective than any of the four other types of trunk stabilization in increasing TrA thickness in healthy subjects.

Purpose: The purpose of this study is to provide an efficient and scientific basis for muscle activity (%MVIC) of RA, EO, VL, HS muscles and balance in soccer players through dynamic lumbar stability exercise and static lumbar stability exercise. Methods: This study included 23 soccer players belonging to D University of J province who attended the program for 30 minutes at a time and three times a week for 4 weeks. Of these 13 attended the dynamic lumbar stability exercise (DLSE) program and 10 the static lumbar stability exercise (SLSE) program. The differences between the effects of the dynamic lumbar stability exercise program and static lumbar stability exercise program were analyzed. Results: To increase muscle activity (%MVIC) and balance (WPL), the dynamic lumbar stability exercise program was more effective than was the static lumbar stability exercise program. 1) The %MVIC of trunk muscle (RA &EO) and lower extremitys muscle (VL & HS) increased from before training to after training in the case of the participants who performed the dynamic lumbar stability exercise. 2) The whole path length (WPL) decreased from before the training to after the training. The 2 groups significantly differed in this regard. Conclusion: Dynamic lumbar stability exercise program helps to improve the balancing ability and muscle activity in a soccer players who requires both muscle activity and balance than does any other players.

Methods : The subjects of the study were 18 patients who showed the symptom of scoliosis. The study classified the patients into two experimental groups, one using an unstable surface and one a fixed surface, and the patients were required to do a lumbar stabilization exercise a total of 12 times for 60 minutes per session, three times a week for four weeks. The study carried out a paired comparison t-test so as to compare differences between measurement values in each experimental group before and after the exercise. Results : Superior iliac spine on the left, there was a significant reduction in the group doing the lumbar stabilization exercise on an unstable surface (p<0.05). Regarding change in sway distance to the left and right directions in the group doing the lumbar stabilization exercise on the unstable surface, there was a significant decrease in both the condition of closed eyes or open eyes (p<0.05). As for change in sway distance in forward-and-backward direction, there was a significant reduction in the condition of either closed eyes or open eyes (p<0.05). Conclusion : The lumbar stabilization exercise on an unstable surface improved the trunk posture of patients with scoliosis symmetrically, and the static balance ability in a standing posture was discovered to be improved. In the future, the lumbar stabilization exercise on an unstable surface may be used as a posture correction and balance increase exercise for patients with scoliosis.
