Objective: To investigate the association between one-leg standing ability and postural control for chronic hemiparetic stroke. Design: Cross-sectional study. Methods: Forty individuals who had a first diagnosis of stroke with hemiparesis before six months and over had participated in this study. To analyze the relationship between one-leg standing ability and postural control in the participants, six clinical measurement tools were used for assessment, including the Timed-Up-and-Go (TUG) test, Berg Balance Scale (BBS), Dynamic Gait Index (DGI), Fugl-Meyer Assessment (FMA), 5 times sit-to-stand (5TSTS) and one-leg standing (OLS). Results: After analyzation, the OLS scores in the more-affected side showed significant positive correlations with BBS scores (r=0.469, p<0.01), DGI scores (r=0.459, p<0.01).and FMA scores (r=0.425, p<0.01). The OLS scores in the more-affected side showed significant negative correlations with TUG score (r=-0.351, p<0.05). The OLS score in the less-affected side showed significant positive correlations with BBS scores (r=0.485, p<0.01), DGI scores (r=0.488, p<0.01) and FMA score (r=0.352, p<0.05). The OLS scores in the less-affected side showed significant negative correlation with TUG scores (r=-0.392, p<0.05) and 5TSTS (r= -0.430, p<0.01). The OLS scores in the more-affected side showed significant positive correlations with the OLS scores in less-affected side (r=0.712, p<0.01). Conclusions: The results of the study suggest that the OLS time may be moderately correlated with static and dynamic postural stabilities and motor recovery following stroke. This study also suggests that the OLS test is as a simple clinical tool for predicting postural control performance for individuals with chronic hemiparetic stroke.

문제 정의
However, the OLS test is a variable that simply explains whether the person can walk independently and safely, and is a tool for identifying persons at high risk of requiring long-term care. The study was conducted to investigate the relationship between OLS ability and postural control for individuals with chronic hemiparetic stroke. The main results of the study were as follows: (1) OLS scores of the more-affected side was positively correlated with static and dynamic postural stabilities, walking abilities, motor recovery following stroke, and sit-to-standing transfers.
This study aimed to investigate the strength of the association between one-leg standing ability and postural control for chronic hemiparetic stroke. This study assessed multiple individual tasks in which these scores were summed to create a composite score (BBS, dynamic gait index (DGI)), and also involved single tasks, such as the timed up-and-go test (TUG) and 5 times sit-to-stand (5TSTS).
This study was a cross-sectional, observational study that included outpatients from a local rehabilitation center to investigate the relationship between OLS ability and postural control for individuals with chronic hemiparetic stroke. The study was approved by the institutional review board of Baekseok University and all participants provided informed consent before the study (IRB No.
This study was conducted to evaluate the association between OLS and postural balance for chronic hemiparetic stroke survivors. This study was a cross-sectional, observational study design, not an experimental study.

This study assessed multiple individual tasks in which these scores were summed to create a composite score (BBS, dynamic gait index (DGI)), and also involved single tasks, such as the timed up-and-go test (TUG) and 5 times sit-to-stand (5TSTS). It was hypothesized that there would be a good relationship among the one-leg standing time, static and dynamic postural stabilities, motor recovery and sit-to-stand transfers in chronic hemiparetic stroke survivors.
제안 방법
This study was a single-blinded research design, and was conducted by two assessors (Lee and Lee) with more than 5 years of evaluation experience except researchers. Six clinical measurement tools were used, which included the OLS, TUG, BBS, DGI, Fugl-Meyer assessment (FMA), and 5TSTS in order to investigate the relationship between OLS ability and postural control. With deciding the examination order by lot, the clinical test and measures were conducted on the participant.
This test has an acceptable test-retest reliability and interrater reliability [10,11]. The TUG test evaluates the mobility of an individual who may have difficulty with postural control, sit-to-stand, and walking abilities. From a seated position, the participant stands up upon command, walks 3 meters, turns around, walks back to the chair and sits down.
The inclusion criteria was as follows: (1) a person who walked independently for 10 meter and over with or without any assistive devices on even surfaces; (2) a person with a modified Ashworth scale score of [2 of the muscles of the hip, knee or ankle area; (3) a person with a Montreal cognitive assessment-Korean version score of ]23; (4) a person who was able to walk independently before the cerebrovascular accident; (5) a person who could follow the assessors’ instructions and could understand the purpose of this study; and (6) a person who had no visuoperceptual impairments.
The study was conducted to investigate the relationship between OLS ability and postural control for individuals with chronic hemiparetic stroke. The main results of the study were as follows: (1) OLS scores of the more-affected side was positively correlated with static and dynamic postural stabilities, walking abilities, motor recovery following stroke, and sit-to-standing transfers. (2) As a result of checking the affected part with the OLS as an independent variable, the OLS of the less-affected side was affected during sit-to-standing transfers only expect for postural stabilities, walking abilities and motor recovery following stroke.
They suggested the findings are in consistent, although several studies have examined the relation between decreasing OLS times and falls. The review had also analyzed the relations between OLS times and ADL abilities. They reported that the OLS test can be used as a marker of a decline in ADL performance, including IADL [20].
The FMA is a stroke-specific, performance-based impairment index developed by Fugl-Meyer and colleagues in 1975. The test involves the assessment of motor functioning, postural balance, sensation and joint functioning for hemiparetic stroke. It can evaluate the disease severity, motor recovery, and therapeutic effectiveness.

대상 데이터
Forty stroke survivors who had received a diagnosis of stroke for the first time that was confirmed with cerebrovascular imaging before 6 months and over (24 males and 16 females, mean aged years, 59.32) were included in this study. The inclusion criteria was as follows: (1) a person who walked independently for 10 meter and over with or without any assistive devices on even surfaces; (2) a person with a modified Ashworth scale score of [2 of the muscles of the hip, knee or ankle area; (3) a person with a Montreal cognitive assessment-Korean version score of ]23; (4) a person who was able to walk independently before the cerebrovascular accident; (5) a person who could follow the assessors’ instructions and could understand the purpose of this study; and (6) a person who had no visuoperceptual impairments.

To analyze the strength of the association between OLS ability and postural control, this study used the Pearson’s correlation coefficient (r).
성능/효과
Table 3 shows the effects of OLS on postural control in participants. After the Durbin-Watson confirmation, it was judged that it was suitable for the multiple regression analysis model as it was close to 2 at 1.871 (TUG), 1,938 (BBS), 1.717 (DGI), 2.382 (FMA), and 1.994 (5TSTS). The BBS (p=0.
If greater than 20 seconds, this may determine when assistance is required for outdoor walking performance. If the test is longer than 30 seconds, it is interpreted that there is a risk of falling, The test shows excellent test-retest reliability expressed by high intraclass correlation coefficients (range 0.431-0.994)[12,13].
The OLS score for the more-affected side showed significantly positive correlations with BBS scores (r=0.469, p<0.01), DGI scores (r=0.459, p<0.01), and FMA scores (r=0.425, p<0.01).
The OLS scores for the more-affected side showed significant positive correlations with OLS scores for the less-affected side (r=0.712, p<0.01).
The OLS scores in the less-affected side showed significant negative correlations with TUG scores (r=−0.392, p<0.05) and 5TSTS (r=−0.430, p<0.01).
The OLS scores in the less-affected side showed significant positive correlations with BBS scores (r=0.485, p<0.01), DGI scores (r=0.488, p<0.01) and FMA scores (r=0.352, p<0.05).
The results of this study showed that OLS time in the more-affected side as well as in the less-affected side may be considered as to have moderate association strength with static and dynamic postural stabilities, motor recovery following cerebrovascular accident and a series of predetermined walking tasks. Therefore, this study suggests that OLS test is a simple clinical tool for predicting postural control performance for chronic hemiparetic stroke survivors.
후속연구
This study was a cross-sectional, observational study design, not an experimental study. Therefore, future studies should consider whether OLS exercise can serve as a simple exercise for the improvement of postural balance and gait in people affected by stroke.
