Objective: The present study was to investigate the discrimination capacity of the Performance Oriented Mobility Assessment-Gait Scale (POMA-GS), for predicting falls in stroke survivors. Design: Retrospective cohort study. Methods: Data including the characteristics and number of falls of 52 chronic stroke patients from a rehabilitation center were collected. The number of falls each subject had experienced in the previous year were investigated through interviews. The subjects were divided into two groups depending on the number of falls: if falls occurred twice or more on the basis of the time of study after stroke, they were defined as the falls group and if there was no fall experience or one fall, they were defined as the non-falls group. The subjects were examined with the POMA-GS, and physical functions were examined using by the One Leg Stand Test (OLST), Sit to Stand Test (SST), 10-m Walk Test, Lower Extremity in Fugl-Meyer assessment (FM-LE), and Trunk Impairment Scale (TIS). The validity of POMA-GS for falls prediction was analyzed. Results: In the POMA-GS, which predicts falls in stroke survivors, the cut-off value was 8.5 (sensitivity 72%; specificity 65%) and the area under the curve was 0.75 (95% confidence interval: 0.60-0.90, p<0.007). There was a significant difference in the OLST, SST, FM-LE, and TIS between the subjects with POMA-GS >8.5 and the subjects with POMA-GS ${\leq}8.5$. Conclusions: The POMA-GS could be a useful tool in predicting falls in stroke survivors, as its discrimination capacity and predictive validity is proven satisfactory.
Objective: The purpose of this study is to develop new balance evaluation index that can discriminate fall risk factors and provide effective interventions for healthy elderly. In order to conduct this study, the balance assessment tools (TUG, mCTSIB, OLST, FRT and BBS) currently used in clinic were re-evaluated using biomechanical analysis. Method: The participants were healthy elderly people over 65 years old, n=26, age: 69.31±3.13 years; height: 154.00±4.12 cm, body weight: 56.13±6.04 kg. The variables are length of CoM-BoS, length of CoP-BoS, range of CoP, mean distance of CoP, mean frequency of CoP, root mean square of CoP, joint angle, ASM (%SL), CoP-CoM angle. Results: As a result of this study, the following items were included in the list of new balance evaluation index for the healthy elderly, showing differences in the biomechanical evaluation based on the clinical evaluation (Inclusion list: TUG, OLST, 8th assessment item of BBS (reaching forward with outstretched arm), 11th item (turning 360 degrees), 13th item (standing with one foot in front), 14th item (standing on one foot)). Conclusion: Based on the results, the new balance evaluation index for the healthy elderly determined through this study can be used to prevent the fall by evaluating the balance ability in various situations that can be experienced in the normal daily life of the healthy elderly.

Purpose: This study examines the effects of elastic band of resistance exercise for balance control of the elderly. Methods: Thirty of eighty participants in experiment subjects who demonstrated balance-impairment through the use of primary screening tests including the one leg standing test (OLST), functional reach test (FRT) and timed up and go (TUG) were selected as subjects. Fifteen subjects that underwent muscle-strengthening exercise using an elastic band were selected as the exercise group and fifteen subjects were selected as a control group. Subjects undertook a home-based exercise program three times per week for 9 weeks. Muscle strength, functional assessment and a balance test were quantitatively measured before and after the exercise regimen. Results: After muscle strengthening exercises, changes in maximal voluntary isometric contraction (MVIC) showed a significant increase in all of the lower extremity muscles of the exercise group subjects. There were statistically significant differences between the exercise and control groups for changes in the OLST, FRT and TUG, which are functional assessments of balance ability, and changes of the unit path length and circumference area, measurement items of quantitative analysis. In addition, from examining correlations between MVIC, balance ability, it was found that an increase of muscle strength in the hip joint group of muscles among the lower extremity muscles had greater improvement in correlation with balance ability in this elderly population. Conclusion: Resistance exercise using elastic bands had significant effects on muscle strengthening in elderly subjects, with a resultant increase of lower extremity muscle strength with significant improvement of balance ability.

PURPOSE: The purpose of this study was to investigate the inter-rater absolute reliability and the concurrent validity of the Tinetti-gait scale that was translated into Korean for chronic stroke patients. METHODS: Fifty-two patients with post-stroke participated in this study. Inter-rater reliability was analyzed by Intraclass Correlation Coefficient ($ICC_{3,1}$) and Kappa coefficient, and absolute reliability was analyzed by the Standard Error of Measurement (SEM), and the Minimal Detectable Change (MDC). Concurrent validity was analyzed by correlating between the Tinetti-gait scale and physical functions. The physical functions were measured by using the Dynamic Gait Index(DGI), 10m walking test(10WT), One Leg Standing Test of affected/non-affected side(OLST), Sit to Stand test(STS), (Fugl Meyer assessment of Lower Extremity(FM-LE). RESULTS: The inter-rater reliability of the Tinetti-gait scale was high; $ICC_{(3,1)}=.91$ (95% CI=.85~.95) (very reliable), the range of Kappa coefficient were .73~.92 (substantial~good). The inter-rater agreement of the each item in Tinetti-gait scale ranged from .74 to .92 (95 % CI=.59~.95) (reliable~very reliable). The SEM and MDC were .56 and 1.55, respectively. In the results of concurrent validity, there were moderate positive correlation between Tinetti-gait scale and DGI (r=.78), 10WT (r=.74), OLST (r=.65~.73), FM-LE (r=67). And there was moderate negative correlation between Tinetti-gait scale and STS (r=-79) (p<.01). CONCLUSION: The Tinetti-gait scale(Korean version) was a reliable and valid tool to measure gait ability in patients with chronic stroke. Thus, it could be a useful tool for examining a gait ability of post-stroke patients. Further study should be conducted to investigate the usability to predict fall risk of post-stroke patients of the Tinetti-gait scale.
Purpose: This study aimed to examine the effects of proprioceptive neuromuscular facilitation (PNF) upper and lower limb coordinated exercises on balance in elderly women. Methods: The study was conducted with 27 elderly women who were at least 65-year-old. The subjects were randomly assigned to a PNF upper and lower limb coordinated exercise group consisting of 14 subjects and an aero step balance exercise group consisting of 13 subjects, and the exercises were performed for 30 minutes, three times per week, for eight weeks. One Leg Stance Tests (OLST), Functional Reaching Tests (FRT), Four Square Step Tests (FSST), and Timed Up and Go (TUB) tests were conducted before and after the exercises to evaluate the subjects' static balance ability and dynamic balance ability. Among the collected data, the subjects' general characteristics were evaluated using descriptive statistics, the intra-group differences of the test results before and after the intervention were compared using paired sample t-tests, and the inter-group differences in the results before and after the intervention were evaluated using independent sample t-tests. The statistical significance level was set to 0.05. Results: Among the OLST, FRT, FSST, and TUG tests, the experimental group showed positive FSST results that were statistically significantly greater than the control group; the results of the other tests were also more positive for this group, but the differences between the groups were not statistically significant. The magnitude of the effects for both groups was clinically significant. Conclusion: Since inter-limb coordinated exercises for PNF applied to elderly women were found to produce good results for both static balance ability and dynamic balance ability, these exercises can be used in exercise programs to improve balance in elderly women.
The purpose of this study was to investigate the effects of home exercise program on the improvement of balance in the elderly. Subjects were twenty members living in Daegu (10 males, 10 females), between 65 and 81 years of age. The subjects for the experimental group were participated in the home exercise program for 8 weeks, between April 2001 and June 2001. The results of this study were as follows: After the exercise program, balance ability by CTSIB in the experiment group improved with no statistical significance. On the other hand, balance ability by OLST was significantly improved in the condition with open eyes than dosed eyes. Balance ability by OLSTR was improved 37.2% (p<0.001) on the hard surface with open eyes and improved 41.1% (p<0.01) on the soft surface with open eyes. Balance ability by OLSTL improved 37.1% (p<0.001) on the hard surface with open eyes and improved 72.5% (p<0.001) on the soft surface with open eyes. Balance ability by BBT also improved 1.7% (p<0.05).
Purpose: The purpose of study was to test the effect of lower extremity muscle strengthening exercise using elastic resistance on balance on elderly women. Methods: Twenty four women who were over 65 years old were randomly assigned to either the experimental group that received the exercise programme (n=12) or to the control group (n=12) that continued normal activities except programme. Exercises included the following 7 different activities; chair squat, knee flection, extension, hip flection, extension, calf muscle raise, ankle dorsiflection. All the participants were subject to 3 tests, including One-Leg Standing Test, Functional Reaching Test, and Up & Go Test. The measurements were made before the excercise, 4 and 8 weeks after the exercise. The data were analyzed by using the two way repeated ANOVA. Results: The results were as follows; As compared with change of balance capacity between groups, a significant difference was shown in the up and go test (p<.05), but not in balance performance clinical test of OLST (p>.05) and FRT (p>.05). Conclusion: The lower extremity muscle strengthening exercise using elastic resistance for the elderly women had some positive effects on the balance. Therefore this intervention can be broadly applied to other elders for preventing falls.
In Korean terminologies, adjectival terms are rare, and the meaning and function associated with adjectives in Indo-European languages are often realized instead in noun form. However, the rarer adjectival terms we, the more they are used in restrictive and repetitive ways in specialized domains. Thus, it is important to distinguish the different senses of these terms. In this work, focusing on semantic modeling in terminology, we distinguish the different senses of adjectival medical terms by applying lexico-semantic criteria (L'Homme, 2004a) and by classifying the semantic category of the arguments of the adjective (Bae and others, 2002). The result not only contributes to enriching medical terminology, but also empirically demonstrates a method for distinguishing the different senses of adjectival medical terms. In this work, we obtained an average of 1.854 senses for each term. We used the KAIST corpus, composed of medical texts (1,500,000 eojeols), and a group of texts on various subjects (40,000,000 eojeols)

Purpose: This study aimed to systematically analyze the reliability and validity of Korean versions of mobility and gait assessment tools for patients with stroke. Methods: Two reviewers conducted an independent literature search and systematically reviewed the literature. Literature published until June of 2017 was searched using search engines for electronic databases. The 2 reviewers reviewed the title and abstract of each article. Among the articles examined, we read the full text of those judged to be suitable for our study. We classified the selected data into research methods and results. The determination was made through mutual agreement. Results: The reviewers selected 5 articles related to the purpose of this study. The DGI was found to be moderately associated with BBS, 10MWT, and TUG in intra-rater reliability (ICC=0.92), inter-rater reliability (ICC=0.88), and concurrent validity tests. The FGA demonstrated a high level of reliability with intra-rater (ICC=0.92-0.95) and inter-rater reliability (ICC=0.91, 0.95). The intra-rater reliability of the RMI was high at ICC=0.98. Its concurrent validity showed a high association with STREAM and BI. The intra-rater reliability of the MAS was ICC=0.75-0.99. Its inter-rater reliability was very high, exceeding 0.99. The inter-rater reliability of the Tinetti-gait Scale was ICC=0.91, and its concurrent validity was moderately associated with the DGI, 10WMT, OLST, FM-L/E, and STS. Conclusion: The results of this study revealed that the reliability and validity of the Korean versions of the mobility and gait assessment tools were high.
