BACKGROUND The Mini-BESTest is a clinical balance test that has shown a high sensitivity in detecting balance impairments in elderly with Parkinson's disease (PD). However, its reproducibility between different raters and between test occasions has yet to be investigated in a clinical context. Moreover, no one has investigated the reproducibility of the Mini-BESTest's subcomponents (i.e. antici...

Resonance frequency analysis (RFA) is the most extended method for measuring implant stability. The stability quotient (ISQ) measure obtained by different RFA devices; however, inter- and intra-rater reliability agreement of these instruments remain unknown. Thirty implants were placed in three pig mandibles. ISQ was measured parallel perpendicular (lingual) to peg axis with Osstell® Beacon, Pe...

BACKGROUND Insight in children's energy balance-related behaviours (EBRBs) and their determinants is important to inform obesity prevention research. Therefore, reliable and valid tools to measure these variables in large-scale population research are needed. OBJECTIVE To examine the test-retest reliability and construct validity of the child questionnaire used in the ENERGY-project, measurin...

Background In order to make objective and intelligent decisions regarding caloric intake for fat loss/physique enhancement, one’s resting metabolic rate should be measured. It is important that the device used to measure resting metabolic rate be valid and reliable. Therefore, the purpose of this study was to establish the interand intra-day test-retest reliability of the Cosmed Fitmate ProTM i...

Although regional alpha power and asymmetry measures have been widely used as indices of individual differences in emotional processing and affective style in younger populations, there have been relatively few studies that have examined these measures in older adults. Here, we examined the short-term test-retest reliability of resting regional alpha power (7.5-12.5 Hz) and asymmetry in a sampl...

This study investigated some aspects of the validity of walking speed recording in 15 normal subjects, 16 trans-femoral amputees and 8 knee disarticulation amputees. The variability and test-retest reliability of walking speed and the influence of simultaneous recording of EMG and goniometry on comfortable and fast walking speeds were studied. The variability between sessions was mainly determi...

We present the initial validation of a two-factor structure of Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT) using ImPACT composite scores and document the reliability and validity of this factor structure. Factor analyses were conducted for baseline (N = 21,537) and post-concussion (N = 560) data, yielding "Memory" (Verbal and Visual) and "Speed" (Visual Motor Speed and R...

OBJECTIVE We examined rater and test-retest reliability of the Preschool Imitation and Praxis Scale (PIPS). METHOD We administered the PIPS to 119 typically developing children ages 1.5-4.9 yr. RESULTS The PIPS demonstrated acceptable intra- and interrater reliability on item level (k(w) = 0.45-1) and scale level (intraclass correlation coefficient ICC = 0.996; 95% CI: 0.968-0.999 and ICC =...

The objective of the study was to assess the internal consistency and test-retest reliability of selected scales from four national and provincial surveys used to study the health status of community-dwelling seniors. Items on physical impairment, psychological well-being, activities of daily living, chronic health problems, social support, and stressful life events were selected from these sur...

Abstract BACKGROUND Improvements in meningioma risk stratification are needed to guide postoperative management. We previously developed and externally validated a targeted gene expression biomarker predicting outcomes radiotherapy response using fresh frozen meningiomas. Here, we present the analytical validity, test-retest cross-platform reproducibility, intra-tumor heterogeneity, formalin fi...
