  • Purpose: This study was done to evaluate the Lasater Clinical Judgement Rubric for use with Korean nursing students. Methods: A methodological study was used to validate the rubric developed by Lasater to assess clinical judgment during nursing simulation. Participants were 34 nursing students at K University in Seoul. Between February and May, 2012, analysis was done of 91 video clips recording performance during simulation. Results: Findings showed reliability and validity of the rubric. For internal consistency, Cronbach's ${\alpha}$ score was .884 and intraclass correlation coefficient was .839, which established reliability. The rubric was validated using the exploratory factor analysis and content validity. The content validity score was 83%, establishing the appropriateness and readiness of the tool. Factor analysis showed that noticing, responding, and reflecting domains had Eigen values of 2.669, 1.991, and 2.912, respectively and were bound, but unlike the original tool in which four factors noticing, interpretation, responding, and reflecting domains were bound. Conclusion: Results of the study indicate that the rubric shows acceptable reliability and validity in Korean nursing students. This evaluation tool for nursing simulation allows nursing faculty to objectively evaluate students' clinical judgment as well as students to reflect on their clinical judgment process during simulation.

  • The purpose of this study was to evaluate the concurrent validity of the double meter inclinometer (DMI) for passive joint range of motion (ROM) in beagle dogs and to compare these results to a universal plastic goniometer (UPG). Fifteen beagle dogs were recruited for this study. Joint ROM was evaluated twice with each device to calculate the intraobserver reliability. The intraclass correlation coefficient (ICC) values of the UPG were good to excellent (> 0.75) for all joint ROM tests. Similar results were obtained with the DMI. The ICC values of the DMI were good to excellent (> 0.75) except in extension of the tarsal joint (ICC = 0.69). The majority of the ICC results between each device were poor (< 0.50) with the exception of six joints. Our findings suggest that the inclinometer can be used for passive joint ROM in veterinary medicine. However, caution should be taken when comparing measured values of passive joint ROM obtained utilizing both the DMI and UPG.

  • This study was undertaken to develop the scapulometer, a measuring tool for scapular winging, and to determine the reliability of scapulometer. Thirty subjects with scapular winging greater than 2 cm participated in this study. Two examiners measured scapular winging using the scapulometer. Standardized measurement position of each subject was as follows: neutral position of shoulder and wrist, $90^{\circ}$ flexion of elbow, and cuff weight of 5% and 10% of body weight (BW) to neutral wrist. The interrater and intrarater reliability were calculated with an intraclass correlation coefficient (ICC) with 95% confidence interval (CI) and standard error of measurement (SEM) at 5% BW and 10% BW. The level of scapular winging was tested between 5% BW and 10% BW with a paired t-test. The interrater reliability was shown to be high at 5% BW (ICC(2,k)=.955, 95% CI=.900~.979, SEM=.07) and at 10% BW (ICC(2,k)=.968, 95% CI=.930~.985, SEM=.06). The intrarater reliability was shown to be high at 5% BW (ICC(2,k)=.921, 95% CI=.842~.961, SEM=.09) and at 10% BW (ICC(2,k)=.906, 95% CI=.813~.954, SEM=.10). The level of scapular winging was significantly different between 5% BW and 10% BW. Conclusively, it is demonstrated that the scapulometer is an objective and qualitative measurement tool for scapular winging.

  • Purpose: This study was designed to investigate inter-rater and intra-rater reliability of navicular drop measurements by clinicians in sitting and standing positions. Methods: Fourteen subjects with pronated foot were recruited. Two physical therapists randomly assessed the same patients on different occasions but on the same day. Almost all patients were assessed on more than one day. The intra-rater and inter-rater reliability of navicular dropwas estimated by calculation of the intraclass correlation coefficient (ICC). Results: The intra-rater reliability of navicular drop measurements ranged from 0.93 to 0.87, the inter-rater reliability from 0.98 to 0.70 with the patient in standing and sitting positions. These results showed good reliability for calculated variables. Intra-rater and inter-rater reliability of navicular drop in standing position was higher than those of sitting position. Conclusion: Although inter-rater and intra-rater reliability of navicular drop in the sitting position was lower than in the standing position, measurement of navicular drop in the sitting position showed good reliability and was acceptable for patients who could not stand alone without assistance. We recommend that having the patient in the standing position is appropriate in navicular drop measurement.

The purpose of this study was to estimated inter-rater and intra-rater reliability of the Scale for Contraversive Pushing (SCP). Methods: Fourteen patients in the acute phase after stroke onset were diagnosed with pusher syndrome. Two physical therapists randomly assessed the same patients on different occasions on the same day. Almost all patients were assessed on more than one day. The inter-rater and intra-rater reliability of the SCP was estimated by calculation of the intraclass correlation coefficient (ICC). Results: The intra-rater reliability of the SCP ranged from 0.87 to 0.97; the inter-rater reliability of the SCP ranged from 0.71 to 0.99 in sitting and standing positions. These results show good reliability for the calculated variables. Conclusion: The results provide support for the use of the SCP in assessing pusher syndrome based on its reliability in stroke patients. It may use the standardized clinical assessments in clinical implication.

  • PURPOSE: Stoke is one of most common disabling conditions and it is still lacking of measuring patient's functioning level. The aim of the study was to develop Korean language version of stroke impact scale 3.0. METHODS: Korean version of stroke impact scale 3.0 was developed in idiomatic modern Korean with a standard protocol of multiple forward and backward translations and an expert reviews to achieve equivalence with the original English version. Interviews with clinicians who were currently managing patients with stroke were also conducted for language evaluation. A reliability test was performed to make final adaptation using a pre-final version. To assess the reliability of the translated questionnaire, the intraclass correlation coefficient (ICC) was calculated for each domain of the scale. RESULTS: Thirty subjects (16 male, 14 female) aged from 20 to 75 years old participated to review the translated questionnaire. Reliability of each domain of the questionnaire was found to be good in strength (ICC=0.74), ADL (ICC=0.81), mobility (ICC=0.90), hand function (ICC=0.80) and social participation (ICC=0.79), communication (ICC=0.77) with total (ICC=0.76). However, domains of memory and thinking (ICC=0.66), and emotion (ICC=0.27) and showed poor reliability. CONCLUSION: This study indicates that the Korean version of SIS 3.0 was successfully developed. Future study needed for obtaining the validity of the Korean version of SIS 3.0.

  • The purpose of this study was to establish reliability and validity of the Northwick Park Neck Pain Questionnaire (NPQ) translated into Korean for neck pain patients. Sixty-two subjects (35 males, 27 females) with neck pain enrolled in the study. They completed a standardized self-administered questionnaire that included pain intensity, sleeping, sensory at night, duration of symptoms, carrying, reading and watching television, working, social activities, and driving. Reliability was determined by intraclass correlation coefficient (ICC) and Cronbach's alpha by internal consistency. Validity was examined by correlating the NPQ scores to the Visual Analog Scale (VAS) score. Test-retest reliability of the translated versions of the NPQ was good ICC(2,1)=.83 (95%CI=.85~.95). Cronbach's alpha value for NPQ was found to be .87 and this was statistically significant (p<.05). The criterion-related validity coefficients was .75 (p<.01). We concluded that the Korean version NPQ was shown to be a reliable and valid instrument for the assessment of neck pain.

  • PURPOSE: This study was conducted to devise a method of preventing water infiltration into the surface electrodes during EMG measurements underwater and on the ground and to check the reliability of Electromyography (EMG) measurements when underwater. METHODS: Six healthy adults were selected as subjects in this study. The measurements in this study were conducted in pool dedicated to underwater exercise and physical therapy room in the hospital building. An MP150 (Biopac Systems, US, 2010) and a BioNomadix 2-channel wireless EMG transmitter (Biopac Systems, US, 2012) was used to examine the muscle activity of rectus femoris, biceps femoris, tibialis anterior, gastrocnemius of dominant side. The subjects repeated circulation tasks on the ground for more than 10 min for enough surface electrode attachment movement. After a 15-min break, subjects performed the circulation task underwater(water depth 1.1m, water temperature $33.5^{\circ}C$, air temperature $27^{\circ}C$), as on the ground, for more than 10 min, and the MVIC of each muscle was measured again. SPSS v20.0 was used for all statistical computations. RESULTS: The maximum voluntary isometric contraction (MVIC) values between the underwater and on the ground measurements showed no significant differences in all four muscles and showed a high intraclass correlation coefficient (ICC) of >0.80. CONCLUSION: We determined that EMG measurements obtained underwater could be used with high reliability, comparable to ground measurements.

  • The purpose of this study was to assess repeatability and reliability of a new phoria test as compared to established phoria tests and to assess the possibility of mobile or online testing using the auto-flashed presentation. Near dissociated phoria was measured using the von Graefe method, the Howell card test, the modified Thorington test, and a new dichromatic card test (Red-Blue Phoria card test; RBP card test) on 109 subjects. The inter-examiner difference and test-retest difference were calculated. With the auto-flashed presentation of the RBP card test, near dissociated phoria was measured and the intraclass correlation coefficient and test-retest repeatability was assessed on 26 subjects. The variation in inter-examiner repeatability was the smallest for the modified Thorington test (+3.1/-2.6). The RBP card test was +3.0/-3.1, the Howell card test was +3.5/-2.7, and the von Graefe test was +6.2/-6.0. The variation in test-retest repeatability was the smallest for the RBP card test (+0.4/-1.4). The modified Thorington test was +1.3/-1.3, the Howell card test was +1.27/-1.45, and the von Graefe test was +1.59/-2.20. The ICC was 0.919 for the auto-flashed presentation of the RBP card test. The RBP card test is considered a highly repeatable method clinically and can be made a useful application for testing in mobile or online.
