BACKGROUND Test-retest reproducibility is of utmost importance in follow-up of right ventricular (RV) volumes and function; optimal slice orientation though is not yet known. We compared test-retest reproducibility and intra-/inter-observer variability of right ventricular (RV) volumes and function assessed with short-axis and transverse cardiovascular magnetic resonance (CMR). METHODS Eighte...

objectives: the percentage of vowel correct (pvc) is one of the indices in the development of articulation and phonological skills in children that can be measured with speech samples that could be extracted from the single word or connected speech tests. the aim of this study is to introduce the pvc scale in persian speaking children and investigate its validity and reliability. methods: this ...

OBJECTIVES To develop a computerized Digit Vigilance Test (C-DVT) with lower random measurement error than that of the DVT and to examine the concurrent validity, ecological validity, and test-retest reliability of the C-DVT in patients with stroke. DESIGN A cross-sectional study. PATIENTS Forty-four patients with stroke. METHODS We developed and tested the C-DVT. To examine the psychomet...

PURPOSE To describe and evaluate a new experimental reference plane for measuring rim area in scanning laser tomography. METHODS The experimental reference plane was positioned so that (1) it always lay entirely below the margin of the optic nerve head (ONH), (2) it remained at a set z-axis distance below the ONH in images of each eye, and (3) it was at a level where variability in rim area i...

abstract objectives, the purpose of this research was to evaluate of the intra-rater and inter-raters reliability of the 10 meter walk test (10 mwt) in 30 adults with spastic cerebral palsy (cp) with subgroup analyses in gross motor function classification system (gmfcs). material & methods, participants  (19 men, 11 women; mean age 27 y and 9 mo) with gmfcs levels below iv (i, ii, and iii) non...

The Symbol Digit Modalities Test (SDMT) and Digit Vigilance Test (DVT), both well-recommended attention tests for schizophrenia, are measures of switching and sustained attention, respectively. The purpose of this study was to investigate the test-retest reliability of the two attention tests in schizophrenia. A rater administered both tests on 147 participants with schizophrenia twice at a 1-w...

The 'Singleton Protocol' was adopted by the Irish Department of Agriculture Fisheries and Food (DAFF) in 1996 to address the incomplete specificity of the single intra-dermal comparative tuberculin test (SICTT) used in Ireland for the detection of animals infected with bovine tuberculosis (bTB). The protocol allows the early restoration of disease-free status to herds with a single reactor brea...

Assessing children’s perceptions of their movement abilities (i.e., perceived competence) is traditionally done using picture scales—Pictorial Scale of Perceived Competence and Acceptance for Young Children or Pictorial Scale of Perceived Movement Skill Competence. Pictures fail to capture the temporal components of movement. To address this limitation, we created a digital-based instrument to ...

OBJECTIVE Multi-frequency tympanometry and its components are extensively used to identify middle ear disorders. However, there are a limited number of studies that have attempted to determine its test-retest reliability. Thus, the present study attempted to determine the test-retest reliability of the different components of multi-frequency tympanometry. MATERIALS AND METHODS The resonant fr...
