Purpose: This study aimed to evaluate the effects of trunk stabilization exercises using a Reformer on trunk control, balance ability, and gait function in chronic stroke patients. Methods: The participants were 24 chronic stroke patients, randomly divided into two groups: trunk stabilization exercise using the Reformer group (TS-R, n = 12) and general trunk stabilization exercise group (GT-E, n = 12). Assessment methods included the Trunk Impairment Scale for trunk control, the AMTI force platform for static balance, the Timed Up and Go test for dynamic balance, and the Dynamic Gait Index for gait function. Assessments were conducted before and after the intervention. The intervention for the TS-R group consisted of bridging exercises using a Reformer, while the GT-E group performed bridging exercises on a mat. All interventions were performed for 17 minutes per session, five times a week, for a total of 20 sessions over four weeks. Statistical analysis was performed using repeated-measures ANOVA to analyze the interaction between groups and time. Results: The results of the repeated measures ANOVA indicated a significant interaction between the groups and time. The TS-R group showed statistically significant differences in all variables before and after the intervention. In contrast, the GT-E group did not show statistically significant differences in any variables before and after the intervention. Conclusion: The findings of this study suggest that trunk stabilization exercises using a reformer are effective in improving trunk control, balance ability, and gait function in chronic stroke patients.

Purpose : This study was to compare the difference Trunk Control Test(TCT), Postural Assessment Scale for Stroke(PASS-TC), and Trunk Impairment Scale(TIS) and its subscales in relation to the difference MBI(Modified Barthel Index), BBS(Berg Balance Scale), and to establish the association between MBI, BBS, Fugl Meyer-motor function(FM-M), and to predict MBI-subscales from the variables. Methods : 58 stroke patients, attending a rehabilitation programme, participated in the study. Trunk control was measured with the use of the TCT, PASS-TC, TIS, and the performance of Activities daily living was obtained by MBI, and dynamic balance ability(by BBS). Trunk control scores from the difference MBI, BBS were compared using the 1-way ANOVA(Mann Whitney U test) and the data were analyzed using Pearson product correlation. Multiple stepwise regression analyses were performed to identify prognostic factors for ADL subscale. Results : Trunk control scores showed significant differences between MBI(F=2.139~13.737, p<.05~.001), BBS(t=3.491~7.705, p<.01~.001). It was significantly related with value of the MBI(r=.25~.50), BBS(r=.38~.68), FMM( r=.31~.48). Stepwise linear regression analysis showed an additional, significant contribution of the TCT, in addition to the PASS-TC, dynamic sitting balance subscale of the TIS for measures of MBI subscales. Conclusion : Measures of trunk control were significantly related with values of MBI, BBS score, so the management of trunk rehabilitation after stroke should be emphasized. The use of both quantitative and qualitative scales was shown to be a good measuring instrument for the classification of the general performance of the stroke patients. Further study about trunk control is needed using a longitudinal study design.

Purpose: The aim of this study was to identify the effects of performing the half squat exercise with Kinesio taping (HSEKT) on trunk and lower extremity muscle activity and balance ability in general university students. Methods: The 32 participants were randomly assigned to either the HSEKT group (half squats with Kinesio taping) or the control group (half squats with sham Kinesio taping). Both groups performed half squats with either Kinesio taping (HSEKT group) or sham Kinesio taping (control group) for 30 min/day, 3 times/week for 6 weeks. The Noraxon mini direct transmission system (DTS) electromyography (EMG) system was used to evaluate trunk and lower extremity muscle activity. BioRescue equipment was used to measure the movement area of the center of pressure with eyes open and eyes closed. The muscle activity of the trunk and lower extremities and the balance ability of all participants were measured before and after the intervention. An independent t-test was used to statistically analyze the pre- and post-intervention EMG and balance ability results. Results: The trunk and lower extremity muscle activity was found to have significantly improved in the HSEKT group and the control group after the intervention (p < 0.05). Also, the balance ability of the HSEKT group differed significantly after 6 weeks of training compared to that of the control group (p < 0.05). Conclusion: The findings of this study show that performing half squats with Kinesio taping had a positive effect on trunk and lower extremity muscle activity and balance ability in general university students.

Objective: The purpose of this study was to evaluate the effects of closed chain lower limb exercise with abdominal breathing exercise on stroke patients and their effects on trunk control ability and balance. Method: The subjects were 40 stroke patients, 19 patients in the experimental group and 18 patients in the control group. The period was 5 weeks, 5 times a week, 30 minutes per session. The experimental group was subjected to a closed chain lower limb exercise with abdominal breathing exercise and the control group was subjected to a closed chain lower limb exercise. The posture assessment scale for stroke(PASS), trunk impairment scale(TIS) were used for trunk adjustment ability, and the balance ability was measured as center of pressure(COP) and limit of stability(LOS). Results: Results of this study showed that the PASS and TIS test significantly increased the experimental group compared to the control group. As a result of comparing the changes of pre and post intervention intervals between the two groups, the TIS test was significantly lower in the experimental group than in the control group, but the LOS test was not significantly increased in the experimental group. Conclusion: Closed chain lower limb exercise with abdominal breathing exercise showed a significant improvement in the trunk control and balance ability of the stroke patients compared to the closed chain lower limb exercise without the abdominal breathing exercise.

Purpose : To find out how action observation training for chronic stroke patients affects their balance and body control abilities in the posture seated in the rehabilitation of stroke. Methods : This study was conducted on 30 subjects who were diagnosed with stroke. The group conducted motion observation training through video clips, while the control group only conducted physical training, and the general physical therapy was performed equally by both counties. The static balance was measured using Biorescue and the dynamic balance was measured using Modified Functional Reach Test (MFRT), Postural Assessment Scale for Stroke, and Trunk Impairment Scale. Results : Static balance showed statistically significant difference in foot pressure (p<.05) as a result of comparison between pre and post exercise training. Dynamic balance was statistically significant (p>.05) as a result of comparing pre and post differences using modified functional reach test. The trunk control ability was statistically significant (p>.001). Comparison between the results of before and after motion observation training showed a statistically significant difference. Conclusion: This study confirmed that exercise training in sitting position was effective for static, dynamic balance ability and trunk control ability of hemiplegic patients due to stroke. These results suggest that the use of motion monitoring in stroke patients may have a positive impact on the diversity and function of rehabilitation.

The purpose of this study was, base on the observation that the leg movement has effect on muscles around trunk, to provide clinical fundamental data to develop effective abdominal draw-in technique by investigating the effect of abdominal draw-in exercise accompanying leg movement on the thickness of transversus abdominis muscle and trunk control ability in patients with stroke. The subjects were assigned randomly to experimental group I (n=9) on which the abdominal draw-in technique is applied and experimental group II (n=9) on which the abdominal draw-in technique accompanying leg movement is applied. The thickness of transversus abdominis muscle in the affected side and the trunk control ability were measured before and after treatment using ultrasonography and trunk impairment scale. A session of 30 minutes per day were performed four days a week for four weeks and the measured outcomes were analyzed. The in-group comparison showed significant difference both thickness of transversus abdominis muscle during abdominal draw-in technique application (p<0.01) and trunk control ability (p<0.001) between before and after treatment. The significant difference between two groups were observed only in trunk control ability (p<0.05). It was concluded that the abdominal draw-in technique accompanying leg movement is an intervention that has positive effect not only on transversus abdominis muscle but also on tunk control ability by inducing more efficient contraction reaction in muscles around trunk through autonomic pelvic movement caused by leg movement.

PURPOSE: This study was conducted to investigate the effects of postural control training using a visual blind board, on head control, trunk control, and the sitting abilities of children with moderate-to-severe cerebral palsy. METHODS: Ten children with moderate to severe cerebral palsy participated in this study. Postural control training with a visual blind board was given for 40 minutes per session, 3 times a week for 4 weeks (12 sessions). Before and after the intervention, head control, trunk control, and sitting abilities were quantified using the head control scale, Korean version-trunk control measurement scale, and the sitting part of the Korean version-gross motor function measure-88, respectively. RESULTS: Postural control with the visual blind board significantly improved the head control ability of children with moderate to severe cerebral palsy (p = .015). Their trunk control abilities also showed significant improvement after the intervention (p = .016). However, their sitting ability did not show a significant change. CONCLUSION: These results showed that postural control training using a visual blind board is effective in improving the head and trunk control abilities of children with cerebral palsy. Further studies with suitable sample sizes and control groups are needed to reach a conclusion about the use of postural control training with visual blind boards for improvement of postural control of children with moderate to severe cerebral palsy.

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.

Background: This research was conducted to understand balance training in trunk control, balance, and walking in stroke patients. Design: Randomized controlled trial. Methods: The subjects included 40 stroke patients, of whom 20 undertook balance training using visual information and the other 20 undertook balance training using balance boards. Using visual feedback, the balance training group used a training program within the static balanced evaluation tool, while the balance training group trained using a balance board. All subjects underwent 20 mins of neurodevelopmental treatment, and both target groups underwent 10 mins each of balance training by using either visual feedback or a balance board. The treatment period lasted a total of 4 weeks, twice a day. Trunk control before and after training was evaluated with the Trunk Impairment Scale. Balance capability was assessed by the Berg Balance Scale, Functional Reach Test, Timed Up and Go test, and Static balance measurement tool. Walking capacity was measured using gait measuring equipment, and cadence and velocity were measured. Results: Both groups showed a significant improvement in their interstitial control, balance, and gait ability after the experiments compared to before the experiments (p<0.05). The difference between the two groups was not significant. The visual feedback balance training group showed a more substantial improvement than the balance board training group. Conclusion: In this study, we found that the balance training combined with visual feedback contributes to improving trunk control, balance, and gait in patients with hemiplegia due to stroke. In addition to this, I believe that balanced training combined with visual feedback can be used as a training method when considering patients who lack interstitial control, balance, and gait ability.

Purpose: The present study was designed to investigate the effect of trunk control training on the labile surface on relative impulse and balance in stroke patients. Methods: A total of 21 participants were assigned to an experimental group (n=11) or a control group (n=10). In addition to conventional therapy, the experimental group received trunk control training on the swiss ball; 20 minutes, 4 times a week, for 8 weeks. Balance ability was evaluated by FRT (functional reaching test) and TUG (time up and go). In addition relative impulse in 6 areas of the foot (hallux, 1st metatarsal head, 2~3 metatasal head, 4~5 metatasal head, mid foot and heel) were measured using the F-scan system to evaluate locomotion ability during gait. Results: Significant differences in the relative impulse were observed in the areas of the 2~3 metatasal head during gait after exercise in both the control group and experimental group (p<0.05). Also, a significant increase was seen in the hallux after exercise in the experimental group (p<0.05), but no such significant increase was seen in the control group (p>0.05). Significant differences were observed in FRT and TUG in the experimental group but no such significant increase was observed in the control group (p>0.05). Conclusion: These results suggest that trunk control training on labile surface improves the balance in stroke patients and has a positive effect on locomotion ability.
