Test-retest reliability and minimal detectable change for center of pressure measures of postural stability in elderly subjects
Abstract Background: Postural instability has been identified as a potential precursor of falls in elderly subjects. Postural stability in quiet stance is commonly assessed with center of pressure (COP) measures. The purpose of this study was to determine testretest reliability and minimal detectable change (MDC) for the center of pressure (COP) measures in the elderly subjects. Met...
متن کاملTest-retest reliability of dynamic causal modeling for fMRI
Dynamic causal modeling (DCM) is a Bayesian framework for inferring effective connectivity among brain regions from neuroimaging data. While the validity of DCM has been investigated in various previous studies, the reliability of DCM parameter estimates across sessions has been examined less systematically. Here, we report results of a software comparison with regard to test-retest reliability...
متن کاملTest - retest reliability of two instruments for measuring public attitudes towards persons with mental illness
BACKGROUND Research has identified stigmatization as a major threat to successful treatment of individuals with mental illness. As a consequence several anti-stigma campaigns have been carried out. The results have been discouraging and the field suffers from lack of evidence about interventions that work. There are few reports on psychometric data for instruments used to assess stigma, which t...
متن کاملA basis for analyzing test-retest reliability.
Three sources of variation in experimental results for a test are distinguished: trials, persons, and items. Unreliability is defined only in terms of variation over trials. This definition leads to a more complet~ analysis than does the conventional one; Spearman’s contention is verified that the conventional approach--which was formulated by Yule--introduces unnecessary hypotheses. It is emph...
متن کاملTest-Retest Reliability of Dynamic Postural Stability Measures in Healthy and Chronic Non-specific Low Back Pain Groups
Objective: The primary aim of the present study was to study the reliability of postural stability measures during whole body dynamic conditions, so they can be used in postural stability evaluations, investigations of injury mechanisms and assessments of treatment efficacy. Materials & Methods: Twelve healthy volunteers and 12 low back pain patients performed repeated trunk bending motions ...
