  • The purpose of this study is to investigate the effect of the hip positions in frontal plane on abdominal muscle activities during bridging exercise. Twenty six subjects who have healthy conditions were asked to perform bridging exercise in three starting positions which are hip abduction, neutral and hip adduction. We used surface electromyography to compare the activities of both external oblique, internal oblique and rectus abdominis muscle. We analyzed the data by using repeated one way ANOVA, The alpha level was set at 0.05. The results showed that the muscle activities of both sides of external oblique, and internal oblique were significantly different among three starting positions. The activity of both sides of rectus abdominis were insignificantly different among three positions. The muscle activities of both sides of external oblique muscle and left internal oblique in bridging exercise with hip adduction position were significantly greater than hip neutral positions. The muscle activity of right internal oblique in bridging exercise with hip abduction positions. Our results suggest that bridging exercise with hip adduction position is recommended to lumbar stabilization exercise and the factor of hip position is important for controlling exercise intensity when designing bridging exercise program.

  • The purpose of this study is to see how the stability of posture due to elastic band during plank movement affects walking. Thirty healthy men in their 20s were given a total of 30 minutes of 10 general plank exercises, 10 plank exercises with two hip joints adduction, and 10 plank exercises with one hip joint adduction. The plank movement was conducted three times a week for a total of six weeks, with a five-minute warm-up. The results of this study are as follows: There was a significant difference between period and group interactions on cadence (p<0.05), with significant difference between the period and group between the left foot on stride length of the left side foot (p<0.05), with significant difference between the period and the period of the interaction between the right foot and the period on stride length of the right side foot (p<0.05), and a one-step change between the right foot and the military interaction on Step time of the right side foot(p<0.05). The conclusion of this study is that the resistance movement on the adduction of both hips increases the instability of the trunk over the normal plank movement and adduction of one hip, thereby enhancing walking ability along with the stability of the trunk.

  • The purpose of this study was to identify the effect of muscular strength, sensation, and spasticity of the hip joint on balance using clinical tools in chronic stroke patients. Thirty-two subjects participated. It were measured muscular strength of the hip flexor, extensor, abductor, and adductor using manual muscle testing, light touch sensibility, and spasticity of the quadriceps using the modified Ashworth scale in the paretic lower extremity. Also, static and dynamic balance were measured by the functional balance scale. Collected data was analyzed by stepwise multiple regression. Muscular strength of the hip abductor, light touch sensibility, and spasticity were associated with static balance(p<0.05) and explanatory power was 80.5%. Muscular strength of the hip abductor and light touch sensibility were associated with dynamic balance(p<0.05) and explanatory power was 77.9%. Thus, it is suggested that muscular strength of the hip abductor and light touch sensibility is considered when providing evaluation and intervention programs for the future in the balance.

  • Background: To improve lumbo-pelvic stability, passive support devices (i.e., a pelvic belt) are recommended clinically. Nevertheless, to understand the influence of passive support on lumbo-pelvic stability, it is necessary to examine the influence of a pelvic belt on the abdominal and hip abductor muscles. Objects: To examine the effects of a pelvic belt on the forces of the hip adductor and abductor muscles and activity of the abdominal muscles during isometric hip adduction and abduction. Methods: This study recruited 14 healthy men. All subjects performed isometric hip adduction and abduction with and without a pelvic belt in a neutral hip position. Load cells, wrapped with a non-elastic belt, were placed above the medial and lateral malleoli of the dominant leg to measure the muscle forces of the hip adductors and abductors, respectively. The forces of the hip adductors and abductors were measured using a load cell during isometric hip adduction and abduction, while the electromyographic activities of the bilateral rectus abdominis, internal oblique, and external oblique muscles were measured. Results: The forces generated by the hip adductors and abductors were significantly greater with the pelvic belt than without (p<.05). No significant differences in abdominal muscle activities between the two conditions were found (p>.05). Conclusion: These findings suggest that use of a pelvic belt could lead to effective strengthening exercise of hip muscles in individuals with sacroiliac joint pain.

  • This study aims to investigate the effect of trunk muscle strengthening exercises on balance performance of sitting posture and muscle tone, targeting the children with spastic diplegic cerebral palsy. 16 children with spastic diplegic cerebral palsy in IV phase of GMFCS were sampled at random and the tests were conducted for 6 weeks, 3 times per week. For experimental groups, only trunk muscle strengthening exercises were conducted and for control groups, only basic physical therapy was conducted. The trunk muscle strengthening exercise consisted of 2 exercises to strengthen abdominal muscles and back muscles. BPM(Balance Performance Monitor) was used to measure balance performance and MMAS(Modified Modified Ashworth Scale) was used to measure muscle tone. As a result, the changes of sitting balance performance in experimental groups and control groups show significant difference in the changes of sway path and sway velocity(p<.05), the comparison of changes in sitting balance performance in between experimental groups and control groups show significant difference in the changes of sway path and sway velocity(p<.05). Knee flexor muscles and hip adductor muscles in both groups show no significant difference in changes of the muscle tone(p>.05). Therefore, the balance performance in both experimental groups and control groups was improved. However, the experimental group had more significant improvement in balance performance and no change in muscle tone was detected in both groups. Thus, these findings show trunk muscle strengthening exercises are effective in improving the balance performance of sitting posture for the children with spastic diplegic cerebral palsy without changing muscle tone.

  • PURPOSE: This study examined the changes in the thickness of the abdominal muscles, including the transversus abdominis, according to the set pressure applied by a pressure biofeedback unit during contractions of the hip adductor muscles. METHODS: After randomizing 40 healthy adult males in their 20 s and 30 s, the participants were instructed to match the pressure gauge indication of the pressure biofeedback device to continue contracting the hip adductor while maintaining it at 10 mmHg (low), 40 mmHg (medium), or 70 mmHg (high). The measurement was taken over five seconds using an ultrasound device. RESULTS: According to the contractile pressure applied to the hip adductor muscle, there was a significant difference in the muscle thickness change of the transverse abdominis muscle between 10 mmHg and 70 mmHg and between 40 mmHg and 70 mmHg. The muscle thickness ratio of the external oblique/abdominal muscle was significantly different between 10 mmHg and 70 mmHg and between 40 mmHg and 70 mmHg. CONCLUSION: Increased contraction pressure on the hip adductor muscle increases the muscle thickness of the abdominal transverse muscle. Interbody stability exercise with contractions of the hip adductor muscle is expected to help increase in the muscle thickness of the hip adductor muscle.

  • Purpose: The purpose of this study was to investigate the effects of plank exercises involving the contraction of the adductor muscle of the hip joint on core muscle thickness and to propose an effective plank exercise method. Methods: A total of 30 healthy young adults (17 males, 13 females) voluntarily participated in the study. The subjects were randomized to the prone plank exercise with hip adductor contraction (n=10), the prone plank exercise (n=10), and the supine plank exercise (n=10) groups. Muscle thickness measurements were taken prior to starting the exercise program and after completing the program at the end of a 4-week period. The muscle thickness of the rectus abdominis (RA), multifidus (MF), external oblique (EO), internal oblique (IO), and transverse abdominis (TrA) muscles were measured using ultrasonography. Each group performed the stipulated plank exercise five times a week as follows: 5 sets of 20 seconds during the first week, 5 sets of 30 seconds in the second week, 5 sets of 40 seconds in the third week, and 5 sets of 40 seconds in the last week. Results: The three different types of plank exercises all showed significantly increased thickness of the RA, MF, EO, IO, and TrA (P<0.05). Furthermore, changes in the thickness of both the MF and TrA were statistically more significant in the groups that did the prone plank exercise with the hip adductor contraction and the supine plank exercise than in the prone plank exercise group (P<0.05). Conclusion: The study results suggest that the prone plank exercise with hip adductor contraction is a more effective method for overall activation of the RA, MF, EO, IO, and TrA than the prone plank exercise and the supine plank exercise.
