Purpose: This study aimed to explore the effects of additional trunk exercises on an unstable surface on the balance and walking ability of individuals with chronic stroke. Methods: Sixteen patients with chronic stroke participated in this study. The participants were randomly assigned to two groups: experimental group (n=8) and control group (n=8). All the participants underwent a typical physical therapy program for 30 min a day. Moreover, the experimental group participated in a 30 min trunk exercise program on an unstable surface, whereas the control group participated in a 30 min trunk exercise program on a stable surface. Both groups performed the exercises five times a week for three weeks. The Berg Balance Scale (BBS) was used to measure changes in balance. The gait variables were measured using the GAITRite system (CIR System Inc., Clifton, NJ, USA) to examine changes in walking ability. Results: Both groups showed a significant intragroup improvement in balance, gait speed, cadence, stride length, and double support period (p<0.05). In the intergroup comparisons after the intervention, the experimental group showed significant improvements over the control group in balance, gait speed, cadence, stride length, and double support period (p<0.05). Conclusion: This study applied additional trunk exercises on an unstable surface to chronic stroke patients, and the results showed a significant improvement in the patients' balance and walking abilities. Therefore, trunk exercise on an unstable surface may be applicable as an intervention method to improve the balance and walking ability of chronic stroke patients.

Purpose: This study investigated the effects of trunk exercise using less-affected extremities on gait and balance in chronic stroke patients. Methods: Thirty subjects with chronic stroke disease were divided into two groups: a trunk exercise group that used less-affected extremities (n=15) and a general trunk exercise group (n=15). All interventions were conducted 30 min a day, 6 times per week, for 3 weeks. Gait parameters were measured before and after the intervention using Zebris FDM-1.5. In addition, all subjects were evaluated using the Trunk Impairment Scale, the Berg Balance Scale, and the Functional Gait Assessment before and after the intervention. Results: Both groups showed improvements on all outcome measured pre- to post-intervention (p<0.05). The groups exhibited significant differences for TIS, BBS, FGA, gait speed, step length, and cadence at post-intervention (p<0.05). Conclusion: This study showed that trunk exercise using less-affected extremities has therapeutic benefits on gait and balance in individuals with chronic stroke disease.

Purpose: The aim of this study was to identify the effects of Pilates mat exercise may improve trunk muscle thickness and balance in healthy adults. Methods: Eighteen healthy adults participated in this study. They were randomly assigned to one of two groups: Pilates mat exercise group (n=9) and the control group (n=9). Subjects in Pilates mat exercise group performed the exercises three days per week for 6 weeks, which consisted of warm up, main workout, and cool down. Trunk muscle thickness of the rectus abdominis (RA), internal oblique (IO), external oblique (EO), transverse abdominis (TrA), multifidus (MF), and erector spine (ES) were measured using an ultrasonography. Balance ability was evaluated using Romberg test and limits of stability (LOS). Measurements were performed before training, 3 weeks after training, and 6 weeks after training. Results: There was a significant difference of RA, EO, IO, MF, and ES according to the main effect of time (p<0.05). There was a significant difference of EO, MF, ES, Romberg, and LOS according to interaction effect between the time and group (p<0.05). There was a significant difference only for LOS according to the main effect of the group (p<0.05). Conclusion: Pilates mat exercise did increase trunk muscle thickness and balance. However, the effect with respect to trunk thickness was limited. Pilates mat exercise appears to be more effective in improving muscles related to trunk extension and balance.

PURPOSE: The purpose of this study was to identify the effects of neck stabilization exercise combined with trunk stabilization exercise on balance and gait function in patients with chronic stroke. METHODS: Twenty-two chronic stroke patients were included in this study. The experimental group subjects (n = 11) performed neck stabilization (15 min) and trunk stabilization (15 min) exercises, while the control group subjects (n = 11) performed trunk stabilization exercise only for 30 min. Before and after the intervention, the subjects underwent static balance and gait testing. RESULTS: The 95% confidence ellipse area, center of pressure (COP) path length, and COP average velocity were significantly lower in both groups after the intervention compared to before intervention (p < .05). The average stance force on the affected side increased significantly in both groups after the intervention (p < .05). The changes in the static balance variables were larger in the experimental group than in the control group. The cadence, gait velocity, and single leg support increased significantly in both groups after intervention (p < .05). The changes in the gait variables were larger in the experimental group than in the control group. CONCLUSION: Trunk stabilization is a beneficial intervention, but the combination of neck stabilization with trunk stabilization is a more effective method to increase the gait and static balance in chronic stroke patients.

PURPOSE: This study was aimed to investigate the effects of pelvic movements-based training on trunk stability and balance during sitting in children with spastic cerebral palsy. METHODS: Ten children with spastic cerebral palsy were matched to an intervention (n=5) or control group (n=5). The intervention consisted of two weeks of pelvic movements-based training, five times a week. All participants were evaluated before, during, and after pelvic movements-based training using a trunk impairment scale (TIS) for trunk stability and a modified functional reaching test for balance during sitting. The collected data were analyzed using Repeated Measures ANOVA and the Mann-Whitney U test. RESULTS: The results of this study were as follows: 1) Significant increases in the TIS score (only dynamic balance) and forward reaching were observed in the experimental group, compared with the control group, after training (P<.05). 2) There were statistically significant time-factor increases within and between the subject' effects, in the TIS score (dynamic balance and total), dominant side, non-dominant side, and forward reaching (P<.05). CONCLUSION: In conclusion, this study showed that for children with spastic cerebral palsy, pelvic movements-based training improves trunk stability and balance during sitting. Further studies will be required to determine the long-term effects of pelvic movements-based training.

Purpose: The purpose of this study was to verify the effect of applying clam exercise on improving trunk control and balance ability in stroke patients. Based on this, we tried to provide clinical information. Methods: In this study, 18 patients with chronic stroke were recruited from a rehabilitation hospital. The patients were divided into two groups: a clam exercise group (9 patients) and a control group (9 patients). After 30 minutes of neuro-development therapy, they performed clam exercise or bridge exercise for 3 weeks, 5 times a week for 30 minutes. A trunk impairment scale (TIS) and a postural assessment scale for stroke patients-trunk control (PASS-TC) were performed to evaluate the subjects' ability to control trunk before and after intervention. Balance ability was measured by Balancia before and after intervention. Results: After the training periods, area 95% COP and weight distribution of the affected side were significantly different from the clam exercise group compared to the control group (p<0.05). Conclusion: Based on the results of this study, in can be seen that the clam exercise is effective in improving the balance ability compared to the bridge exercise. Maintaining the standing posture requires muscle strength of the hip abduction and extension, which is the result of the clam exercise selectively strengthening these muscles. Therefore, if you want to provide intervention to improve the balance of stroke patients, it is recommended to perform a clam exercise.

Purpose: Balance and walking ability are important elements of functional independence for people with stroke and are major goals in rehabilitation. These abilities require trunk performance, but most chronic stroke patients reach a plateau in their rehabilitation. Therefore, the purpose of this study was to investigate the effects of a self-training trunk program to improve balance and walking ability in people with stroke, and to suggest such a self-training program for integrated rehabilitation of people with stroke. Methods: The study recruited 7 people with stroke. The subjects performed trunk training for 30 min per day, 6 days per week, for 3 weeks. Participants were measured on the Trunk Impairment Scale (TIS), the Berg Balance Scale (BBS), the Korean Activities-specific Balance Confidence (K-ABC) scale, the Falls Efficacy Scale (FES), the Functional Gait Assessment (FGA), the 6 Minute Walk Test (6MWT) and a gait analysis to measure the training effects. Statistical analysis used the Wilcoxon signed-rank test as a non-parametric statistical test. Results: TIS was not significantly different after the self-training trunk program, but BBS (p>0.05), K-ABC, and FES were significantly improved after the training program (p<0.05). Furthermore, the 6MWT, stride/height %, and one-leg stance were significantly improved after the training program (p<0.05), but cadence, stance, and swing duration were not significantly different after the training (p>0.05). Conclusion: These results suggest that a self-training trunk program should be integrated into stroke rehabilitation to improve balance and walking ability, and further research is needed to develop the program to be more effective for chronic stroke patients.

PURPOSE: This study aimed to determine the effect of active trunk training in the sitting position on balance and energy consumption in early stroke patients. METHODS: The subjects of this study were twenty four early stroke patients were recruited and randomly divided into two groups; experimental group (n=12) and control group (n=12). The subjects in the experimental group participated in active trunk training (20 min) and conventional physical therapy (20 min) five times a week for four weeks. The control group conducted general balance exercise (20 min) and conventional physical therapy (20 min) five times a week for four weeks. The outcomes were assessed using the Berg balance scale, Timed up and go test and energy cost and physiological cost index. RESULTS: Both groups showed a significant increase in their Berg balance scale and significant decrease in their Timed up and go test score, and energy cost and physiological cost index (p<.05). Compared to the control group, the experimental group experienced a greater increase in the Berg balance scale (p<.05) and a larger decrease in the timed up and go test score, and energy cost and physiological cost index (p<.05). CONCLUSION: We suggest that active trunk training in the sitting position may be effective in improving balance and energy consumption in early stroke patients. Thus, active trunk training is important for such patients. Further studies are needed to better understand the effectiveness of trunk training in early stroke patients.

Purpose: This study aimed to investigate the effect of active vibration exercise on trunk muscle activity, balance, and activities of daily living in patients with chronic stroke. Methods: Twenty-four patients with chronic stroke were randomly assigned to an experimental (n=12) or a control (n=12) group. The experimental group performed an active vibration exercise workout for 20 minutes a day five times a week for 4 weeks using a flexi-bar. Trunk muscle activity was measured using surface electromyography. Balance was measured using the Berg balance scale. Activities of daily living were measured using the functional independence measure. Results: The intragroup comparison showed significant differences in the rectus abdominis, internal oblique, and external oblique muscle activity values, Berg balance scale score, and functional independence measurement values in the experimental group. The intergroup comparison showed that differences in the rectus abdominis and internal oblique external oblique muscle values, Berg balance scale score, and functional independence measurement value for the experimental group were significantly related to those in the control group. Conclusion: Based on these results, this study proved that the active vibration exercise effectively improved trunk muscle activity, balance, and activities of daily living in patients with chronic stroke.
