Reliability and Accuracy of Echocardiography for Follow-up Studies after Intervention

1987

By two-dimensional echocardiography limitations of M-mode echocardiography have been eliminated. As a direct and noninvasive method two-dimensional echocardiography seems to be an ideal method for analysis of left ventricular function in follow-up studies. In relation to other methods there are no limitations concerning x-ray exposure, physicians and patients safety. Before different studies can be discussed, reliability and accuracy of two-dimensional echocardiography have to be evaluated. Beat-to-beat, day-to-day, intra- and interobserver variability will be discussed, followed by description of follow-up studies after intervention.

Physical Examination Tests for Screening and Diagnosis of Cervicogenic Headache: A Systematic Review

2016

It has been suggested that differential diagnosis of headaches should consist of a robust subjective ex-amination and a detailed physical examination of the cervical spine. Cervicogenic headache (CGH) is a form of headache that involves referred pain from the neck. To our knowledge, no studies have sum-marized the reliability and diagnostic accuracy of physical examination tests for CGH. The aim of this study was to summarize the reliability and diagnostic accuracy of physical examination tests used to diagnose CGH. A systematic review following PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines was performed in four electronic databases (MEDLINE, Web of …

Interrater reliability between scorers from eight European sleep laboratories in subjects with different sleep disorders

2004

Interrater variability of sleep stage scorings is a well-known phenomenon. The SIESTA project offered the opportunity to analyse interrater reliability (IRR) between experienced scorers from eight European sleep laboratories within a large sample of patients with different (sleep) disorders: depression, general anxiety disorder with and without non-organic insomnia, Parkinson's disease, period limb movements in sleep and sleep apnoea. The results were based on 196 recordings from 98 patients (73 males: 52.3 +/- 12.1 years and 25 females: 49.5 +/- 11.9 years) for which two independent expert scorings from two different laboratories were available. Cohen's kappa was used to evaluate the IRR o…

Four-subtest short-form of the WAIS-IV for assessment of patients diagnosed with schizophrenia.

2021

Abstract Introduction The present study aimed to obtain a short form of the Spanish version of the WAIS-IV for patients diagnosed with schizophrenia that requires about half an hour to be administered. The reduced test can be very useful in clinical and research settings when an estimation of the intelligence quotient (IQ) is required to decide about intervention programs or to describe the sample. Materials and methods A sample of 143 patients participated in the study, 91 out of them were the test group, and the other 52 were used for a cross-validation analysis. To increase the content validity, the decision was made to create a short form composed of a subtest of each of the four cognit…

Reliability Assessment of Scores from Video-Recorded TGMD-3 Performances

2017

This study examined the intrarater and interrater reliability of the Test of Gross Motor Development—3rd Edition (TGMD-3). Participants were 60 Finnish children aged between 3 and 9 years, divided into three separate samples of 20. Two samples of 20 were used to examine the intrarater reliability of two different assessors, and the third sample of 20 was used to establish interrater reliability. Children’s TGMD-3 performances were video-recorded and later assessed using an intraclass correlation coefficient, a kappa statistic, and a percent agreement calculation. The intrarater reliability of the locomotor subtest, ball skills subtest, and gross motor total score ranged from 0.69 to 0.77, a…

THERapy–Related InterACTion (THER-I-ACT) in Rehabilitation—Instrument Development and Inter-Rater Reliability

2021

Objective: To develop an instrument for the observation of therapeutic communication interactions during rehabilitation sessions and test its inter-rater reliability.Methods: The new instrument THER-I-ACT (THERapy–related Inter-ACTion) has been designed to assess both the frequency and timing of therapeutic interactions in the thematic fields information provision, feedback, other motivational interaction, and bonding. For this inter-rater reliability study, a sample of stroke survivors received arm rehabilitation as either arm ability training, arm basis training, or mirror therapy, or neglect training as individually indicated. Therapy sessions were video-recorded (one for each participan…

Resonance frequency analysis-reliability in third generation instruments : Osstell mentor ®

2012

Few studies assess repeatability and reproducibility in registers of resonance frequency analysis (a value of dental implant stability). Objective: Few studies assess repeatability and reproducibility in resonance frequency analyses (implant stability evaluation). This study is aimed at assessing reliability (repeatabilty and reproducibility) in the Osstell Mentor® system using the intraclass correlation coefficient (ICC) as the statistical method. Study Design: ISQ measurements of RFA were carried out by means of the Osstell Mentor ® instrument in 58 implants in 19 patients. Six measurements were performed on each implant by means of two different Smart-Pegs (I and II). Three consecutive m…

A step towards a field based agility test in team sports. A perspective on return to play criteria

2017

Introduction: Agility performance tests can be limited by the requirement for force plates, timing gates and expensive camera systems (Correia et al., 2012; Green, Blake, & Caulfield, 2011) making application into rehabilitation programs practically challenging. The aims of this study were to assess the reliability of a field based 1v1 agility test encompassing perceptualaction performance that could be replicated in applied settings. A secondary aim was to assess the relationship between the 1v1 agility test with a range of physical performance tests including the commonly used Y step test (Paul, Gabbett, & Nassis, 2016). Methods: Twenty-eight male rugby union players volunteered (Mean ± S…

The Short Demoralization Scale (SDS): A new tool to appraise demoralization in palliative care patients.

2017

ABSTRACTObjective:The Demoralization Scale (DS) is the most widely used measure for assessing demoralization. Following the recent clamor for brief assessment tools, and taking into account that demoralization has proved to be a symptom that needs to be controlled and treated in the palliative care setting, a shorter scale is needed. The aim of the present research is to introduce and evaluate the Short Demoralization Scale (SDS).Method:We employed a cross-sectional design that included a survey of 226 Spanish palliative care patients from the Hospital General Universitario de Valencia. We employed the SDS, the DS, and the Hospital Anxiety and Depression Scale (HADS).Results:The confirmator…
