OBJECTIVES To describe the influence of the reading order (chronological v paired) on radiographic scoring results in ankylosing spondylitis. To investigate whether this method is sufficiently sensitive to change because paired reading is requested for establishing drug efficacy in clinical trials. METHODS Films obtained from 166 patients (at baseline, 1 year, and 2 years) were scored by one ...

Purpose: The purpose of this study was to test the effect of individualized music on agitation for homedwelling patients with dementia. Method: One group pre-post test was used for research design and a total of 26 subjects participated in this study. Individualized music intervention was subjects’ listening to their preferred music for 30 minutes prior to peak agitation time twice a week for a...

Purpose: The ability of the human organism to recover its autonomic balance soon after physical exercise cessation has an important impact on the individual's health status. Heart rate variability widely used as a non-invasive technique at rest, during and after exercise for the assessment of the autonomic nervous system activity on the heart and the balance between the sympathetic and parasymp...

Considering the need to adequately prescribe training, the aim of this study was to compare the effect of isotonic resistance training at 0.44 and 1.75 rad·s -1 on gains in muscular strength. Fourteen healthy volunteers were stratified into slow (SG: 0.44 rad·s -1; n = 8; 26 ± 7 yr; 66 ± 12 kg) and fast (FG: 1.75 rad·s-1; n = 6; 28 ± 7 yr; 55 ± 9 kg) groups exercising squat and bench press (1 s...

The bacteriology of 20 paired samples of breast milk was analysed to find out if discarding the first few millilitres would reduce the amount of bacterial contamination in breast milk donated to a hospital milk bank. The first sample was the initial 2-3 ml collected from the opposite breast to that first suckled by the baby, and the second was a midstream sample from the same breast. There was ...

We aim to determine which of a set of competing models is better statistically, that is, on average. A way to define “on average” is to consider the performance of these algorithms averaged over all the training sets that might be drawn from the underlying distribution. When comparing more than two means, an ANOVA F-test tells you whether the means are significantly different from each other, b...

So far, resting state functional connectivity (RSFC) has been performed mainly by seed correlation analysis (SCA) on functional MRI (fMRI) studies. In previous studies, the seeds are usually selected on the basis of prior anatomical information or previously performed activation maps. In this paper, we proposed a novel way to select the desired seeds by taking the natures of resting state data ...
