Inter- and intra-rater reliability of the manual handling component of the WorkHab Functional Capacity Evaluation

Abstract: The WorkHab Functional Capacity Evaluation (FCE) is widely used in Australian workplace injury management and occupational rehabilitation arenas; however, there is a lack of published literature regarding its reliability and validity.Purpose. This study investigated the intra- and inter-rater reliability of the manual handling component of this FCE.Method. A DVD was produced containing footage of the manual handling components of the WorkHab conducted with four injured workers. Therapist raters (n == 17) who were trained and accredited in use of the WorkHab FCE scored these components and 14 raters re-evaluated them after approximately 2 weeks. Ratings were compared using intraclass correlation coefficients (ICCs), paired sample t-tests (intra-rater), chi-squared (inter-rater) and percentage agreement.Results. Intra-rater agreement was high with ICCs for the manual handling components and manual handling score showing excellent reliability (0.94–0.98) and good reliability for identification of the safe ...

Finger circumference measurements: inter- and intra-rater reliability

Abstract: Background. Finger oedema can occur for a variety of reasons, including traumatic injuries to the fingers and as a consequence of stroke or diabetes. The purpose of this study was to determine the intra- and inter-rater reliability for finger circumference measurements. Methods. Eight hand therapists assessed the middle finger circumference of 11 healthy adults using the Richardson Products finger circumference device for three trials over two testing days. Intraclass reliability analysis and analysis of variance were used to assess the consistency and stability of measures. Level of significance was set at P � 0.05. Results. Significant differences (P , 0.001) were found between raters for circumference measurements with a range difference of 0.5 cm. Intrarater reliability was 0.98‐0.99 (single measure intraclass coefficient). Interrater reliability coefficients ranged from 0.94 to 0.95. Conclusions. These results provide clinicians with evidence for using a specific finger circumference device and issues associated with various therapists assessing finger circumference. A device with a way of assessing tension at the end of the tape measure or cloth pulled around the finger is warranted.

Research on Reliability Evaluation Methods of Electrical Meter

Abstract: The paper introduces the present situation and problems in reliability evaluation research of electrical meters,and proposes that the reliability prediction and reliability accelerating testing are two important technologies for reliability assessment of electrical meters,of which the realization methods,peculiarity and limitation are discussed. Based on the technical features of meters and the requirements of reliability evaluation technology,the reliability prediction based on component stress method and reliability test combining accelerated life testing with accelerated degradation testing are proposed,which are the most valuable methods applied in reliability evaluation of electrical meters in theoretical and practical engineering.

Reliability and Minimal Detectable Change in the Gait Assessment and Intervention Tool in Patients With Multiple Sclerosis

Abstract: Background Gait impairment is one of the main causes of disability in people with multiple sclerosis. The Gait Assessment and Intervention Tool is an observational gait scale that assesses kinematic parameters using video recordings. Objective To study intra- and interrater reliability and the minimal detectable change of the Gait Assessment and Intervention Tool in individuals with multiple sclerosis. Design Observational study. Setting Multiple Sclerosis Foundation. Participants Thirty-five participants with multiple sclerosis were assessed (12 men, 23 women; 47.7 ± 11 y; Expanded Disability Status Scale = 4.32 ± 1.4). Interventions Not applicable. Main outcome measurements Intra- and interrater reliability of the Gait Assessment and Intervention Tool was assessed for each limb using the Intraclass Correlation Coefficient. In addition, the minimal detectable change was calculated. Results The Intraclass Correlation Coefficient for the intrarater reliability was found to be excellent for the total score both for the right side (.91; 95% confidence interval 95% CI .85-.95) and the left side (.93; 95% CI .88-.96). The intraclass correlation coefficient for the interrater reliability was .91 (95% CI .85-.95) for the right side, and .93 (95% CI .88-.96) for the left side. The minimal detectable change for the intrarater reliability was 1.19 points for the right side and .77 for the left side. Conclusions The Gait Assessment and Intervention Tool exhibits excellent intra- and interrater reliability and a small minimal detectable change for people with multiple sclerosis.
