김현성,오승준 대한통합의학회 2023 대한통합의학회지 Vol.11 No.1

Purpose : The purpose of this study is to compare the balance ability between subjects with chronic ankle instability and normal people and the center of pressure displacement during the sit to stand and stand to sit. Methods : The subjects of this study were 63 who met the inclusion criteria and were classified into normal group (n=33) and chronic ankle instability group (n=30). The displacement of the center of pressure during sit to stand and stand to sit was measured. And the limit of stability and Y-balance tests were performed to measure the balance ability. Independent t-test was conducted to compare center of pressure displacement and balance ability between groups, and pearson correlation was conducted to analyze the correlation between the center of pressure displacement and balance ability. Results : In the case of the center of pressure displacement, there was a significant difference between the two groups during sit to stand and stand to sit. In the case of balance, both limit of stability and Y-balance test showed significant differences between the two groups. At the time of sit to stand, the center of pressure displacement showed a significant correlation with balance abilities, and at the time of stand to sit, the center of pressure displacement showed a significant correlation with Y-balance test. Conclusion : Chronic ankle instability shows that there is a lot of sway in the body due to compensation to replace the decrease in ankle joint range of motion when performing sit to stand and stand to sit due to sensory input damage such as decrease in ankle range of motion and decrease in ankle proprioception. Chronic ankle instability is expected to have a negative effect on our daily lives in life. The results of this study will serve as the basis for the dynamic approach to objective evaluation, treatment, and prevention of chronic ankle instability.

Purpose: The aim of this research was to investigate the effects of self-sit-to-stand training on balance ability and sit-to-stand ability in hemiplegic stroke patients using a multisensory feedback device. Methods: A total of 19 stroke patients participated in this study, and they were divided into two groups: 10 underwent self-sit-to-stand training using a multisensory feedback device, and 9 underwent sit-to-stand training with a physical therapist. In both groups, sit-to-stand training was performed for 30 min, 3 times a week, for 6 weeks. The subjects also underwent physical therapy twice a day for 30 min, 10 times a week, for a total of 60 sessions. Balance ability was evaluated using the AFA-50 and Berg Balance Scale. Sit-to-stand ability was evaluated using the five times sit-to-stand test. Results: Sway length, pressure, and total pressure all significantly increased in both groups, and there was no difference between the two groups. The Berg Balance Scale results showed that balance ability significantly increased in both groups, and there was no difference between the two groups. The five times sit-to-stand test results showed that sit-to-stand ability significantly increased in both groups, and there was no difference between the two groups. It was found that the self-sit-to-stand training using a multisensory feedback device had a positive effect on balance control and sit-to-stand ability. When the two groups were compared, no difference in balance ability or sit-to-stand ability was observed. Conclusion: The findings of this study indicate that self-sit-to-stand training using a multisensory feedback device is as effective as sit-to-stand training with a physical therapist. Hence, self-sit-to-stand training using a multisensory feedback device could be an effective home-based exercise protocol for hemiplegic stroke patients to improve their balance and sit-to-stand abilities.

( Su-jin Kim ),( Ho-hee Son ) 대한물리의학회 2021 대한물리의학회지 Vol.16 No.4

PURPOSE: This study compared the effects of sit-to-stand training with various foot positions combined with visual feedback on the postural alignment and balance. METHODS: Thirty stroke patients were assigned randomly into three groups of standing with a symmetrical foot position (SSF) (n = 10), asymmetrical foot position with the affected foot at the rear (SAF) (n = 10), and visual feedback and asymmetrical foot position (SVAF) (n = 10). Sit-to-stand training with different foot positions was performed for 30 minutes a day, five times a week, for a total of four weeks, and the effects on postural alignment and balance were assessed. RESULTS: The angle between the midline and scapula peak of the affected side was decreased significantly at sitting and thigh-off in the SAF group and at sitting, thigh-off, and standing in the SVAF group (p < .05). The angle between the midline and scapula peak of the non-affected side was increased significantly at sitting and thigh-off in the SAF group and at sitting, thigh-off, and standing in the SVAF group, the difference in the angle between the scapular peaks of the left and right sides was decreased significantly at sitting and thigh-off in SSF group, and at sitting in SAF group (p < .05). In the SVAF group, the angle at sitting, thigh-off, and standing was decreased significantly (p < .05). A comparison of the balance ability showed that BSS in the SVAF group was improved significantly (p < .05). CONCLUSION: Based on these results, the postural alignment and balance ability were improved in stroke patients who participated in sit-to-stand with visual feedback and asymmetrical foot position training.

Purpose : The purpose of this study was to examine the differences in sit-to-stand movement and static standing balance between young adults and older adults Methods : Thirty young adults and thirty older adults participated in this study. The Good Balance System was used to assess participants`` sit-to-stand movement and static standing balance. The sit-to-stand movement was measured as mediolateral and anterioposterior displacement of the centre of pressure (mm/s) while sit-to-stand on a force platform, and time required to complete a sit-to-stand movement on a force platform. The static standing balance was measured as mediolateral and anterioposterior displacement of the center of pressure (mm/s) and velocity moment (mm2/s) while standing on a force platform with opened eyes and with closed eyes. Result : A significant difference was found in the mediolateral and anterioposterior center of pressure displacement and the time required to complete a sit-to-stand movement of the two groups (p<.05). A significant difference between the groups was found as to mediolateral centre of pressure displacement and the velocity moment when standing with opened eyes and with closed eyes (p<.05). Conclusion : In conclusion, older adults showed decreased sit-to-stand movement and static standing balance ability compared to the young adult. Clinicians should consider sit-to-stand and balance training for older adult.

Can Functional Assessment Tools Reflect Balance Abilities at 3 Months after Total hip Arthroplasty?

( Min-woo Kim ),( Young-uk Ryu ) 대한물리의학회 2018 대한물리의학회지 Vol.13 No.4

PURPOSE: This study was conducted to determine if the Harrison hip score (HHS), a tool for assessing hip joint function, and the Burg balance scale (BBS), a general balance assessment tool, actually reflect the balance ability of total hip arthroplasty (THA) patients 3 months after surgery. In addition, this study investigated the initial weight distribution strategy for bilateral lower extremity after THA surgery to understand the balance of THA patients. METHODS: Fourteen 3-month THA patients performed static dual standing and sit-to-stand (STS) tasks. Ground reaction forces on each leg were collected to calculate the weight distribution symmetricity (SWD), and the HHS, functional HHS (f-HHS), and BBS were evaluated. Correlation analyses between SWD and the HHS (also f-HHS) and BBS were then applied to the THA patients. RESULTS: The correlations between functional evaluation tools (HHS, f-HHS, BBS) and SWD were weak strength for the static balance task, but moderate for the dynamic STS task. Among the evaluation tools used in the present study, f-HHS was most useful for evaluation of dynamic balance ability. CONCLUSION: The results suggest that use of HHS, f-HHS, and BBS as functional evaluation tools does not provide meaningful information regarding balance ability, but that they are useful for evaluating dynamic balance ability of THA patients. The dynamic balance ability at 3 months after THA seems to be under development.

박재효,김영미,이나경 대한물리치료학회 2015 대한물리치료학회지 Vol.27 No.3

Purpose: This study aimed to improve the asymmetrical weight-bearing ratio, by applying different repetitive sit-to-stand training methods to the paretic-side foot of hemiplegic patients, as well as to provide the necessary information for applying balance training with hemiplegic patients. Methods: The subjects were divided into two groups: a spontaneous foot group and an asymmetrical foot group. They all performed repetitive sit-to-stand training five times a week for a total of six weeks. The sit-to-standing movement was studied using standardized clinical tests. The Biodex Balance System, Time up and go test (TUG), 5 times sit-to-stand test (5XSST), and functional reach test (FRT) were used to measure the static and dynamic standing balance of the patients. Results: In the balance system measurement, the results for the overall index, ant-post index, med-lat index, fall risk index, 5XSST, and FRT after the training differed significantly between the comparison groups (p<0.05). In the evaluation of dynamic balance, the differences in TUG did not differ significantly between the comparison groups after the training (p>0.05). Conclusion: The study found that the asymmetrical group showed significant increases in static and dynamic balance in comparison to the spontaneous group after repetitive sit-to-stand training. Based on this result, it is clear that training in an asymmetrical position with the paretic foot back can increase the left-right stability limit and the anterior-posterior stability limit, thus improving balance control.

김현성,오승준 한국인지운동치료협회 2023 한국신경인지재활치료학회지 Vol.15 No.2

목적: 뇌졸중 환자를 대상으로 무작위 높이 변화가 제공되는 환경에서 앉은자세에서 일어서기 훈련을 실시하여 정적 및 동적 균형에 미치는 영향을 알아보고자 한다. 방법: 정적 균형은 눈 뜬 상태의 선 자세 정적균형, 눈감은 상태의 선자세 정적균형, 안정성 한계를 측정하였으며 동적 균형은 다섯 번 일어서기 검사, 기능적 팔 뻗기검사를 측정하였다. 훈련에 따른 그룹 내 균형능력의 변화를 비교 분석하기 위해 대응표본 t-검정(paired t-test)을 실시하였다. 또한 훈련에 따른 그룹 내 균형능력의 변화량을그룹 간 비교 분석하기 위해 독립표본 t-검정(independent t-test)을 실시하였다. 결과: 그룹 내 전⋅후 비교에서 정적 및 동적 균형 모두유의한 변화를 보였으며(p<.05), 그룹 내 변화량에 따른 그룹 간 비교는 눈 감은 상태의 선 자세 정적 균형을 제외하고정적 및 동적 균형 모두 유의한 변화를 보였다(p<.05). 결론: 본 연구의 훈련이 뇌졸중 환자의 정적 및 동적 균형에 유의한 효과가 있음을 확인하였으며 특히, 훈련 시 좌석의 높이를 무작위로 제공하는 것이 뇌졸중 환자의 균형능력회복을 위한 새로운 재활방법으로 임상에서 활용되어 재활의 다양한 방향성을 제시할 것으로 사료된다. 추후 연구는다양한 질환군에게 무작위 훈련의 적용이 필요하며 다양한평가도구 기반 훈련 효과에 대한 다각도의 연구들이 필요할것으로 사료된다. The present study aimed to compare the effects of sit-to-stand training on randomized seat height and balance in 22 stroke patients who were randomly divided into two groups. Each group underwent assessment three times per week for six weeks. For static balance, line position static balance with eyes open and closed and limits of stability were measured. For dynamic balance, the sit-to-stand and functional reach tests were performed five times. Variations in static and dynamic balance were compared using paired and independent t-tests. Changes before and after sit-to-stand training in the groups revealed significant changes in both static and dynamic balance (p<.05). However, there were no statistical differences between the groups before and after training in the line position static balance with eyes-closed test (p>.05). The training examined this study had a significant effect on static and dynamic balance in patients who experienced stroke. In particular, providing a random seat height during training has been used clinically as a new rehabilitation method to restore balance in this patient population. Various directions are anticipated to be explored. To generalize the results, future research will require the application of training to various disease groups and multifaceted studies investigating the effectiveness of training based on various evaluation tools.

김현영,문현임,채유현,이태임 대한재활의학회 2018 Annals of Rehabilitation Medicine Vol.42 No.4

Objective To investigate the dose-related effect of trunk control training (TCT) using Trunk Stability Rehabilitation Robot Balance Trainer (TSRRBT) in chronic stroke patients with poor sitting balance. Methods This was a retrospective study of 38 chronic stroke patients with poor sitting balance that underwent TCT with TSRRBT. The participants were assigned either to the low-dose training (LDT) group (n=18) or to the high-dose training (HDT) group (n=20). In addition to the conventional rehabilitation therapy, the LDT group received 5 sessions of TSRRBT intervention per week, whereas the HDT group received 10 sessions of TSRRBT intervention per week. The outcome measures were the scores on the Trunk Impairment Scale (TIS) and its subscales, Berg Balance Scale (BBS), Functional Ambulation Classification (FAC), and the Korean version of Modified Barthel Index (K-MBI). All outcome measures were assessed before the training and at the end of the 4-week training. Results After the 4-week intervention, TIS, BBS, FAC, and K-MBI scores showed improvement in both LDT and HDT groups. Furthermore, the improvements in TIS scores and its subscales were significantly greater in the HDT group than in the LDT group (p<0.05). Conclusion TCT using TSRRBT could be an additional treatment for the conventional rehabilitation therapy of chronic stroke patients with poor sitting balance. HDT may provide more beneficial effects on improving patients’ sitting balance than LDT.
