Balance is a complex motor skill that depends on interactions between multiple sensorimotor processes and environmental and functional contexts. Many rehabilitation specialists believe that balance assessment under multitask conditions may be a more sensitive indicator of balance problems and falls than balance assessment in a single-task context. Functional Gait Assessment has many tasks that allow for testing under multitask conditions. The purpose of this study was to determine the concurrent validity between the Functional Gait Assessment (FGA), Berg Balance Scale (BBS), and Timed "Up & Go" Test (TUG) in patients with stroke. One hundred and five participants with at least 3 months post stroke and able to walk at least 6 m with or without a mono cane, participated in this study. Concurrent validity between the FGA, BBS, and TUG was assessed using Spearman rank order correlation. The FGA correlated with the BBS (r=.80, p<.01) and TUG (r=-.77, p<.01). The good and moderate correlation between the FGA, BBS, and TUG establishes the concurrent validity of the FGA in patients with stroke. These measures provide clinicians with valuable information about patients' functional balance capabilities.

Purpose: This study was conducted to develop a Korean version of the trunk control measurement scale (TCMS) and examine the reliability and concurrent validity of the K-TCMS in children with cerebral palsy. Methods: Subjects for the study were 23 children with cerebral palsy (CP)(mean age: 84.70 months) recruited from one CP clinic. For the interrater and test-retest reliabilities, four raters (A, B, C, D) measured the K-TCMS two times using video clips with an interval of two weeks. For the concurrent validity, the Korean version of the gross motor function measure (K-GMFM) was chosen. Inter-rater reliability and test-retest reliability of the three K-TCMS subscale (static sitting balance, dynamic sitting balance and dynamic reaching) scores and the total scores were investigated using the intra-correlation coefficient ($ICC_{3,1}$). Spearman's correlation coefficient (r) was calculated to investigate the concurrent validity. Results: The inter-rater reliability of the K-TCMS subscales and total scores were all high ($ICC_{3,1}=0.968-0.992$). For the test-retest reliability, $ICC_{3,1}=0.827-0.962$. The concurrent validity between the K-TCMS's total and three subscale scores and K-GMFM's total score were r=0.600-0.667. Conclusion: The results suggest that the K-TCMS can be used in clinical and research settings as a standardized tool for CP children. The K-TCMS might be also useful for selecting treatment goals and planning interventions for children with cerebral palsy.

Purpose: The purpose of this study was to evaluate the reliability and validity of the Korean version of Diabetes Empowerment Measurement Scale Short Form (DES-SF) for use with diabetic patients in Korea. Methods: A cross-sectional descriptive study was used with 107 participants. Bilingual nursing professionals performed translation and reverse translation. Reliability and validity such as face validity, construct validity, and concurrent validity were conducted. To assess the concurrent validity, the correlation coefficients between the Korean version of the DES-SF and a concurrent scale (Diabetes Self-Efficacy Scale, DSES) were calculated. Results: In the explanatory factor analysis, a uni-dimension was proposed, the one factor accounted for 49.4% of total variances. The Korean version of the DES-SF correlated with a concurrent variable such DSES for reliability of the Korean version of the DES-SF, Cronbach's ${\alpha}=.85$. Conclusion: The findings show that the Korean version of the DES-SF is reliable and valid for evaluating empowerment in patients with diabetes in Korea.

Purpose: The purpose of this study was to determine the concurrent validity between Figure-of-8 Walking Test (F8W), Berg Balance Scale (BBS), Four Squared Step Test (FSST), and Timed UP and GO Test (TUG) in patients with stroke. Methods: Forty two participants (26 men, 16 women, $55.0{\pm}11.72$) with at least three months post stroke who were able to walk at least 10 m without walking aid participated in this study. Assessment of concurrent validity between the F8W (time and steps) and BBS was performed using Spearman rank order correlation and between the F8W (time and steps), FSST and TUG assessed using Pearson correlation. Results: The time of the F8W showed correlation with BBS (r=-0.46, p<0.01), FSST (r=0.64, p<0.01), and TUG (r=0.81, p<0.01), and steps of the F8W showed correlation with BBS (r=-0.43, p<0.01), FSST (r=0.47, p<0.01), and TUG (r=0.51, p<0.01). Conclusion: The F8W is a valid measure of balance and walking skill among patients with stroke and may provide complementary information with regard to dynamic balance and functional walking for the real life of stroke patients.

The purpose of this study was to assess the concurrent validity and reliability of goniometric measurement of joint motion. Subjects were 40 healthy university students. Measurements were performed by 4 inexperienced physical therapy students. Four different instruments were used and three readings were taken with each instrument in random order making a total of 12 readings for flexion of the right elbow of each subject. Goniometers used were 1. universal 2. fluid-based goniometer/inclinometer 3. digital LCD goniometer 4. electronic goniometer/torsiometer. The results were as follows: Concurrent validity was highest (r= .94) with the universal and digital LCD tools. Interrater reliability (Pearson Product Moment Correlation) was good for each tool. Interrater reliability calculated by ICC(2,1) was highest (.96) with the tensiometer and lowest (.78) with the digital LCD goniometer. Intrarater reliability calculated by ICC was excellent (${\geq}.90$) for all instruments. These results show that concurrent validity, intrarater and interrater reliability are very good in the used of all four types of goniometers/inclinometer/tensiometer, even with inexperienced raters. These results confirm the almost universal reliance on hand held goniometers for joint measurement by physical therapists as being a reliable practice. Further research should be done clinically with actual patients.

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 : The purpose of this study was to validate the Korean version of Partners In Health scale (PIH-K) which is used to measure the self-management of patients with chronic illnesses in Korea. Methods : Translation of the 12-item PIH-K was conducted according to the World Health Organization guidelines. Data from 306 participants who took medicines over 3 months by doctor's prescription were collected from October to November 2017. Validity such as content validity, construct validity, and concurrent validity were conducted using content validity index (CVI), exploratory and confirmatory factor analyses (CFA). To evaluate concurrent validity, the correlation coefficients between the PIH-K and concurrent scales (Self-As-Carer Inventory) were calculated. The reliability of the PIH-K was examined using the internal consistency and test-retest reliability tests. Results : The CVI of the PIH-K was 0.91. According to the CFA, factor loadings for four factors ranged from .64 to .97, which explained 67.5% of the total variance. The PIH-K was significantly correlated with concurrent variables such as those on the Self-As-Carer Inventory. The Cronbach's ${\alpha}$ was .86 and the intraclass correlation coefficient for the two-week test-retest reliability was .88. Conclusion : Findings show that the PIH-K is reliable and valid in measuring self-management of patients with chronic illnesses.

Purpose: The aim of this study was to investigate if the 7-item Berg balance scale (BBS) 3-point, which is a short form of the BBS (SFBBS), has compatible psychometric properties in comparison with the original BBS, and also to study the concurrent validity using a 10-meter walk test (10mWT) and a timed up and go test (TUG), which are widely used with SFBBS in clinical settings. Methods: A total of 255 patients who had experienced stroke participated in this cross-sectional study. We used results obtained from 188 patients who completed both 10mWT and TUG. The three levels in the center of the BBS were collapsed to a single level (i.e.,0-2-4) to form the SFBBS. The concurrent validity was assessed by computing the Spearman coefficients for correlation among outcome measures and in between each outcome measure and the SFBBS. As there were four outcomes, the corrected p-value for significant correlation was 0.013 (0.05/4). Results: Spearman coefficients for correlations and evaluation instruments for concurrent validity revealed significantly high validity for both of SFBBS and BBS (r=0.944). 10mWT and TUG were -0.749 and -0.770 respectively, which are in the high margin and are statistically significant (p>0.000). Conclusion: SFBBS has sound psychometric properties for evaluating patients with stroke. Thus, we recommend the use of SFBBS in both clinical and research settings.

PURPOSE: A good, valid, and feasible tool for evaluating sit to stand (STS) is needed to help clinicians quantify the STS ability of stroke patients and people with balance disorders. The purpose of this study was to evaluate the concurrent validity of the Nintendo Wii Balance Board (WBB) and a force plate during STS and gait. METHODS: Seventeen healthy adults performed five trials of STS and gait on the WBB placed on the force plate. The force plate and the WBB were compared in regard to center of pressure (COP) and ground reaction force (GRF) data that were collected simultaneously. The variables used for analysis were time (s), integral summation (%), COP path length (mm), COP x range, and COP y range, all of which were measured for both tasks. Counter (%), peak (%), and rebound (%) were analyzed for STS, and $1^{st}$ peak (%), min peak (%), and 2nd peak (%) were analyzed for gait. The concurrent validity was analyzed using an intraclass correlation coefficient (ICC) and a standard error of measurement (SEM) with a 95% confidence interval. RESULTS: The concurrent validity of the WBB for STS ranged from fair to good (ICC=.701~.994, SEM=.029~3.815). The concurrent validity for gait was good (ICC=.869 ~.989, SEM=.007~2.052) aside from path length and x and y ranges of COP (ICC=-.150~.371, SEM=3.635~4.142). CONCLUSION: The GRF of the WBB has a good validity for STS and gait analysis. The WBB is remarkably portable, easy to use, and convenient for clinically assessing STS and gait.
