PURPOSE: This study examined effects of the untact trunk stabilization exercise program on muscle thickness, trunk strength, maximal expiratory flow, and static balance. METHODS: The subjects were 20 normal adults divided into 10 in the contact exercise group and 10 in the untact exercise group. The trunk stabilization exercise program was conducted for four weeks. The muscle thickness was measured using ultrasound. The maximal expiratory flow was measured using Personal Best Full Range Peak Flow Meter. The static balance was measured through Bio-rescue; and the trunk muscle strength was measured by bending the upper body forward and measuring the time for maintaining the posture. RESULTS: Both contact and untact exercise groups showed significant differences in muscle thickness, muscle strength, maximal expiratory flow, and static balance (p < .05). A significant difference in muscle thickness on ultrasound was observed between the contact and untact exercise groups (p < .05). CONCLUSION: Activation of the transverse abdominal muscle requires accurate instructions of the contact exercise, but despite environmental constraints, the untact exercise program is as effective as the contact exercise for improving muscle strength, maximum expiratory flow, and static balance.

Purpose: Recent studies have indicated that applying different inclination angles and suspension devices could be a useful way of performing exercises that include the co-activation of the trunk muscles. Present study was to examine the influences of changes in the inclination angle during trunk muscle activity while engaging in a bridge exercise with a suspension device. Methods: 18 healthy, physically active male volunteers completed three trunk inclination angles (15°, 30°, and 45°) for bridge exercise variations. The surface electromyography responses of the rectus abdominis, internal oblique (IO), erector spinae (ES), and rectus femoris (RF), as well as the subjective difficulty (Borg RPE score), were investigated during these bridge exercises. Results: The bridge with a 45° inclination angle suspension significantly increased the muscular activities of the RA and RF and increased the Borg RPE scores (p<0.05). The bridge with a 15° suspension significantly elevated the ES activities when compared to the other conditions. Conclusion: The present study demonstrated that a higher inclination angle could not activate the overall trunk muscles during the bridge exercise. The RA and RF produced greater activation during the bridge exercise with the higher inclination angle. On the other hand, the activities of the erector spine were greater during the bridge exercise with the lower inclination angle. The present study suggests that applying a low trunk inclination angle for the supine bridge exercise is suitable for activating the erector spine muscles.

Purpose: The purpose of the study was to identify the effects of proprioceptive neuromuscular facilitation (PNF) training and robot rehabilitation training on trunk stability and standing balance in individuals with chronic stroke. Methods: There were 30 patients with chronic stroke, divided into two groups: 15 subjects who received PNF and robot training (the experimental group) and 15 subjects who received standard conservative training (the control group), that participated. The experimental group received treatment for 60 min: 30 min of conventional physical therapy, 15 min of PNF training, and 15 min of robot training. The control group received conventional physical therapy for 60 min. Trunk stabilization (trunk impairment scale) and standing balance (center of pressure, limit of stability, modified functional reach test, and Berg balance scale) were measured before and after intervention. Results: Within each group, both the experimental and control groups significantly improved after the intervention in all tests; however, the experimental group showed greater improvement in scores on the trunk impairment scale, the center of pressure, the limit of stability, the modified functional reach test, and the Berg balance scale. Conclusion: The study verified that PNF training and robot training had a positive influence on trunk stability and standing balance indices in patients with chronic stroke.

PURPOSE: This study was carried out to examine the changes in the trunk control ability and hand grip when the abdominal draw-in maneuver using breathing was applied to stroke patients, and provide basic data regarding the trunk stabilization exercise. METHOD: After randomly placing patients in group I-applying the existing abdominal draw-in exercise and group II -applying the abdominal draw-in exercise using breathing, the intervention program was performed ten times per set (five sets per session), once a day, four times a week, for a total of four weeks. For the pre-tests before the intervention, trunk damage and hand grip were measured. After the four weeks of intervention, post-tests were conducted in the same way as the pre-tests for analyzing the study results. RESULTS: Both groups had significant differences in trunk control ability and hand grip (p < .05). The comparison between the two groups showed, significant differences only in the trunk control a ability(p < .05). CONCLUSION: The abdominal draw-in exercise using breathing led to the efficient contraction of abdominal muscles, which implies this is a more effective intervention to improve the trunk control ability.

Background: Excessive hamstring (HS) activation due to the weakness of the gluteus maximus (GM) causes pain in the hip joint. A single-leg deadlift is a hip extensor exercise, especially GM, that includes functional movements in daily life and complex multi-joint training. In single-leg deadlift, the muscle activity depends on the forward trunk lean angle, and it's necessary to study which muscles are used dominantly depending on the angle. Objects: The purpose of this study was to compare the effect on the muscle activity of the GM and HS during single-leg deadlift according to different forward trunk lean angles and the ratio of the GM vs HS (GM/HS). Methods: Twenty-one healthy female participants were recruited. The muscles activities of the GM, HS and the GM/HS ratio were measured through electromyography during single-leg deadlift according to three condition of forward trunk lean angles (30°, 60°, and 90°). Results: The GM and HS activities significantly differed among three conditions (p < 0.05). GM/HS ratio was significantly higher at 30° and 60° of forward trunk lean compared to 90°. Moreover, the GM activity was significantly higher at 60° of forward trunk lean than at 30° (p < 0.05). Conclusion: The single-leg deadlift at 60° of forward trunk lean is a proper GM muscle strengthening exercise.

Purpose: The purpose of this study was to identify the effects of general exercise after blood flow restriction on trunk muscles thickness in children with spastic cerebral palsy. Methods: Twenty children with cerebral palsy were assigned randomly to an experimental (n = 10) or a control (n = 10) group. The experimental group performed general exercise after blood flow restriction, while the control group performed general exercise alone. The study used an ultrasonic instrument to measure trunk muscles thickness. The Wilcoxon signed-rank test was used to determine differences before and after treatment, and the Mann-Whitney U test was used to determine differences between treatment groups. Results: From a comparison within the groups, the experimental and control groups showed significant difference in trunk muscle thickness after the experiment (p < 0.05). In a comparison between the two groups, the experimental group showed more significant difference in trunk muscle thickness than the control group (p < 0.05). Conclusion: Based on these results, general exercise after blood flow restriction effectively improves trunk muscle thickness in children with cerebral palsy.

Background: This study examined the effects of the bridge exercise with trunk rotation on the thickness of body trunk muscles, including external oblique, internal oblique, and transverse abdominis in healthy male adults. Design: Randomized controlled trial Methods: Twenty-four men were evenly divided into a trunk rotation bridge exercise group and a basic bridge exercise group by drawing lots. The two groups performed the respective exercise for thirty minutes, three times a week for six weeks. repeated measure analysis of variance (ANOVA) was used after distinguishing between three different time points before the experiment, three weeks after the experiment, and six weeks after the experiment. The significance level was set at 0.05. In case an interaction between time and group existed, the paired t-test was used to examine the within-group difference. The independent-sample t-test was used to check the between-group difference. The significance level was set at 0.05. Results: All the men showed a significant change over time in their external oblique, internal oblique, and transverse abdominis muscles. An interaction between time and group was also found (p<0.05). Conclusion: The bridge exercise with trunk rotation causes a meaningful difference in the thickness of external oblique, internal oblique, and transverse abdominis muscles. Therefore, this study proposes the use of this exercise for lower-back stabilization in future research and clinical settings.

Background: The compression of 7th cranial nerve by arteries is one of the various causes of hemifacial spasm (HFS). A few previous studies were revealed the relation between the compression of 7th cranial nerve and common trunk anomaly. We evaluated the common trunk anomalies in patients with HFS using MRI and MRA. Methods: From January 2001 to December 2005, 41 consecutive patients (9 men, mean age $54.5{\pm}12.6$) with HFS underwent MRI and MRA. T2 axial images and time-of-flight angiographies were reviewed for identification of the compression at root exit zone by two neuroradiologists and one neurologist. Results: Thirty-seven patients showed neurovascular compression on the lesion side. Twenty patients of them were shown the compression of 7th cranial nerve by anterior inferior cerebellar artery (AICA), and seventeen patients of them were shown the compression by posterior inferior cerebellar artery (PICA). Twenty-four patients of the thirty-seven patients had common trunk anomaly. In control, twelve of twenty-one subjects had common trunk anomaly, that the frequencies of common trunk anomaly of two groups were 58.8% in HFS and 57.1% in controls. In the twenty-four patients with common trunk anomaly, eighteen patients had dominant-AICA, and six patients had dominant-PICA. The rate of nerve compression by common trunk anomaly in the HFS with unilateral common trunk, dominant-AICA was 76.5% and dominant-PICA was 100%. Conclusions: This study also revealed that AICA was most common compressive artery. There was no difference between the HFS groups and control groups in frequency of common trunk anomaly. Thus, we could not demonstrate the relationship between common trunk anomaly and HFS.
