The purpose of this study was to determine the intra-rater and inter-rater reliability of various forward head posture measurements. Ten healthy adults (age, $20.4{\pm}2.2$ yrs; height, $164.0{\pm}5.5$ cm; weight, $58.7{\pm}7.3$ kg) participated in the study. They were free of injury and neurologic deficits in the upper extremities and neck at the time of testing. The subjects were asked to perform head forward posture by under the guidance of physical therapists. Markers were placed on the C7 spinous process, mastoid process, tragus of the ear, outer canthus, and forehead. Measurement 1 for forward head posture assessment was measured as the angle between the horizontal line through C7 and the line connecting the C7 spinous process with the tragus of the ear. Measurement 2 was measured as the angle between the C7 spinous process, the mastoid process and the outer canthus. Measurement 3 was measured as two kinds of angles the HT (head tilt) angle is between the line from the midpoint of forehead to the tragus line and Y-axis at the tragus point. The NF (neck flexion) angle is between the line from the tragus to the C7 line and the Y-axis at the C7. Intra-rater, inter-rater reliability and coefficient of variation was assessed by comparing the measured values from three kinds of measurements of forward head posture. The intra-rater reliability was indicated by intraclass correlation coefficients [ICC(1,1)] and inter-rater reliability was shown by intraclass correlation coefficients [ICC(3,k)]. The results of study were as follows: ICC(1,1) values for intra-rater reliability of three measurements were in the 'excellent' category. ICC(3,k) values for inter-rater reliability of three measurements were also in the 'excellent' category. The coefficient of variation of method 2 had a lower value than method 1 and method 3. This data means that the measured value of method 2 was less scattered. Further research is needed to determine whether the validity of all measurements is revealed in the 'excellent' category.

Objective: The aim of this study was to determine the intra-rater and inter-rater reliability of the dual rehabilitative ultrasound imaging (D-RUSI) when simultaneously measuring muscle thickness changes at rest and during co-contraction of the biceps brachii (BB) and triceps brachii (TB). Design: Cross-sectional study. Methods: This study included 36 healthy participants (23 men, 13 women). The participants sat on a chair in a comfortable position with a cushion placed under their elbow to maintain a 90-degree elbow flexion angle. The muscle thickness of the biceps brachii and triceps brachii was measured twice using the D-RUSI by two examiners during resting and co-contraction states. One week later, the same procedure was performed once again. Results: The intra-class correlation coefficients (ICCs) for intra-rater reliability ranged from 0.887 to 0.989 and the confidence interval was within an acceptable range of 0.778 to 0.994. The standard error of measurement (SEM) values ranged from 0.303 to 0.866 and the minimal detectable change (MDC) values ranged from 0.84 to 2.40. The ICCs for inter-rater reliability ranged from 0.758 to 0.925. The SEM values ranged from 0.702 to 1.486 and the MDC values ranged from 1.95 to 4.12. Conclusions: The use of the D-RUSI of the BB muscle had a very good intra-rater reliability and very good inter-rater reliability at the resting state, and a, good inter-rater reliability at the co-activation state. ICC values showed very good intra-reliability and inter-reliability for the TB muscle. the D-RUSI is a useful tool for simultaneously measuring the thickness of two muscles when the BB is an agonist and the TB is an antagonist during co-activation of the upper arm.

The purpose of this study was to compare the intra-rater and inter-rater reliability of three methods for measuring iliotibial tract length in 40 knees of 20 subjects. The measurements were performed by two examiners and one assistant. The length of the iliotibial tract was measured using three methods: the first used a modified Ober test with an inclinometer, the second used a modified Ober test with a marker, and the third used active adduction test with a marker in the supine position. Each examiner used the three methods in two sessions. For the first method, the inclinometer value was recorded manually. For the second and third methods, Image J analysis software was used to analyze the photographs taken. The intra-rater and inter-rater reliability of the measured value was assessed by means of intra-class correlation coefficients [ICC (3,1)] and the standard error of measurement. The intra-rater reliabilities of the three methods were excellent (ICC=.97, .95, and .94, respectively), and the inter-rater reliabilities of the first and second methods were fair to good (ICC=.64 and .65, respectively). The inter-rater reliability of the third method was excellent (ICC=.88). Our results suggest that the active adduction test is an objective and qualitative measurement method for measuring iliotibial tract length. We recommend that the active adduction test be used for measuring iliotibial tract length in the clinical setting.

The purposes of the current study were to (1) estimate the inter-rater agreement for visual assessment of scapular downward rotation (SDR), (2) develop the scapular downward rotation index (SDRI) as a method to measure SDR objectively and quantitatively, and (3) analyze the intra- and inter-rater reliability of the SDRI. Twenty subjects with scapular downward rotation syndrome (SDRS) were recruited for this study. The visual assessment and the measurement for the SDRI were conducted by two examiners in two sessions each. The SDRI [$(a-b){\div}a{\times}100$] is calculated with the measurement of two linear distances: One is a perpendicular distance from the root of the scapular spine to the thoracic mid-line (a), and the other is a perpendicular distance from the inferior angle of the scapula to the thoracic mid-line (b). Cohen's kappa coefficient was calculated to estimate the inter-rater agreement for visual assessment. Intra-class correlation coefficients (ICCs) with a 95% confidence interval (CI), the standard error of measurement, and minimal detectable differences were calculated to assess intra- and inter-rater reliability of SDR measurement using the SDRI. The results indicated that the kappa coefficient of inter-rater agreement for visual assessment was fair (${\kappa}=.21$). The intra-rater reliability of SDR measurement using the SDRI was excellent for examiner 1 (ICC=.92, 95% CI=.78~.97) and good for examiner 2 (ICC=.82, 95% CI=.55~.93). The inter-rater reliability was moderate (ICC=.73, 95% CI=.32~.89). These findings showed that SDR measurement using the SDRI for subjects with SDRS may be considered reliable and better than the visual assessment.

Purpose: This study was a prospective survey to evaluate the Korean Triage and Acuity Scale (KTAS) inter-rater reliability and to identify discordant areas in the KTAS classification between nurses and paramedics in emergency department (ED). Methods: Inter-rater reliability were evaluated using triage deta from January 11 to May 31, 2019. A convinience sample of a total of 800 patients who visited an emergnecy medical center in Incheon (400 adult and 400 pediatric patients in this study) were selected. The triages of this study a pair of one nurse and one paramedic performed triage at the same time, using the KTAS, Inter-rater reliability for the KTAS was evaluated with the weighted kappa. Results: The inter-rater reliability of the KTAS evaluated by weighted Kappa between nurse-paramedic KTAS score of adult patients was .71, and .66 for pediatric patients. Both were in the level considered as substantial. Among causes of triage discordance, the most frequently identified discordant item in triaging adults was the difference in the measurement of pain intensity (28.0%). For both adult and pediatric patients, multiple chief complaint was identified as the major discordant factor. In triaging pediatric patients the body temperature assessment by subjective judgments was the highest discordant item (50.7%). Conclusion: The study result suggested that the KTAS demonstrated a reasonable level of inter-rater reliability and functioned as a standardized triage tool for emergency medical services. In order to improve the inter-rater reliability and classification competence, it is necessary to revise the current all-integrated KTAS provider course to be differentiated for each job group.

BioRescue ($RMIng{\acute{e}}nierie$, Marseille, France) is able to assess dynamic and static balance when a test subject stands or sits over the platform. Although previous studies have examined the reliability of other balance measurement methods, little research has been conducted on the reliability of equipment such as BioRescue. This study examined the intra-rater and inter-rater reliability of BioRescue during balance assessment. Thirty-four healthy adults participated as subjects and two physical therapists participated as examiners to determine intra- and inter-rater reliability. BioRescue was used to conduct measurements during footprint (area and pressure), Romberg, and limit of stability tests. The footprint area and limit of stability tests yielded intra- and inter-rater reliability ICC values above 0.60 in all directions. However, the footprint pressure and Romberg tests yielded values below 0.60 in all directions. BioRescue showed good inter-rater and intra-rater reliability in measurements during footprint area and limit of stability tests. However, because the values of limits of stability show the difference between experienced and unskilled, skill is required for the accuracy of the equipment.

The purpose of this study was to evaluate inter-rater reliability of the amplitude and first knee extension angles in deep tendon reflex test by using an electrical hammer. Twenty-five healthy adults participated in the study. Compound muscle action potential is elicited by tapping the knee tendon with an electrical hammer in deep tendon reflex tests. The amplitude and knee extension angle were simultaneously measured. The mean value of the amplitude and the knee extension angles through three time trials for each tester, are used for determining the inter-rater and Intra-class Correlation Coefficients (ICCs) reliabilities. According to the results, the ICCs of the amplitude is .280 and that of the knee extension angle is .789. Pearson correlation coefficients of the amplitude of the action potential and the knee extension angles are .685, showing significant statistically moderate correlation. Inter-rater reliability in the amplitude was not significant. More objective and quantitative deep tendon reflex tests should be done to obtain higher reliability in further studies.

Background: Pes planus, or flat foot, causes lower limb malalignment and foot pain during walking or exercise. Therefore, a highly reliable evaluation method to accurately diagnose flat feet is necessary. This study investigated the intra-and inter-rater reliability of the navicular drop test in different postures. Design: Cross sectional study. Methods: Forty healthy volunteers performed the navicular drop test in three different combinations of non-weight-bearing and weight-bearing postures (standing/standing, sitting/sitting, and sitting/standing). Two examiners alternately performed the measurements five times in each subject, and in each posture. Significant differences in measurements were obtained among the three postures, with the highest navicular drop being observed in the sitting/standing posture. Results: Inter-rater reliability was high in the sitting/standing and sitting/sitting postures. Intra-rater reliability was high in all three postures. In the sitting/sitting and sitting/standing postures, large navicular drop values and high inter- and intra-rater reliability were observed. Conclusion: Therefore, the sitting/standing and sitting/sitting postures are recommended for use in navicular drop tests to diagnose flat feet.

The purpose of this study was to examine the inter-rater reliability of the Korean translation of the GMFM(Gross Motor Function Measure). Three licensed physical therapists with varying amounts(2 - 6 years) of clinical experience served as raters. Thirty patients with cerebral palsy were subjects for this study. Subjects were 22 boys and 8 girls, aged 1 to 8 years. Reliability of each dimension and each total score of the GMGM were analyzed using ICCs(intraclass correlation coefficients). The reliability of each dimension score ranged from .76 to .98, with the walking, running, and jumping dimension having higher reliability values. The reliability of the total dimension score was .94. We conclude that the GMFM has inter-rater reliability for assessing gross motor function in patients with cerebral palsy.
