The Study on the Rater Reliabilities of Physical Therapy Students Pediatric Balance Scales Items

Abstract: PURPOSE: The purpose of this study is to examine assessment of test-retest reliability for 13 items of pediatric balance scales, then the intrarater reliability among the raters. METHODS: Study participants included 6 children with spastic cerebral palsy who could walk. Raters were consist of seventy-four, 2nd year physical therapy major students. The children`s ability to achieve physical balance was wideotaped for PBS items. The raters watched the tapes and evlauated each child twice. Test-retest reliability was analyzed using the Spearman correlation, and interrater reliability was analyzed using the Kendall`s coefficient of concordance for ranks. RESULTS: The total PBS scores averaged 49.22 and 50.06 for first and second tests. Test-retest reliability of PBS individual items were between low and high. The low itmes were 3 items, and high were 4 itmes. Interrater reliability were low agreement. CONCLUSION: Based on the study, the pediatric balance scale is an effective evaluating tool for measuring functional balance of school age child. However, the agreement of students or beginner`s interpretation is necessary in conjunction to this study results. On top of that, it is important to provide detailed explanation and repetitive training, which improves the analysis reliability. Also, each category subscores level for the pediatric balance scale must be examined carefully in conjunction to performing test, only after improving match quality via preceding practice.

New software TPLAN for reliability evaluation of transmission systems

Abstract: The structure and features of TPLAN,a software package for evaluating transmission system reliability,are presented.TPLAN has four levels of reliability assessment: deterministic contingency analysis,probabilistic assessment for system troubles,probabilistic load curtailment assessment,and cost effectiveness analysis.The process of reliability assessment for probabilistic load curtailment assessment is described,and reliability assessment was conducted for Yunnan Power Grid in 2009 by using TPLAN.

Basic Terms of Reliability

Abstract: Basic terms are explained, such as reliability, failure, fault, limit state, quality, safety, re‐ pair, renewal, maintenance, availability and dependability, inherent and operational reli‐ ability.

Test-Retest and Intrarater Reliability of Assessing Tibial Rotation Range of Motion by Two Devices

Abstract: Rotational motion at the tibia is important for proper lower extremity function, however, normative values vary, and the motion is seldom assessed. Clinicians are increasingly using smartphones for assessing range of motion. The purpose of the study was to assess the reliability of the embedded iPhone 6 compass app and universal goniometer for measuring tibial rotation range of motion. Secondarily, the purpose was to compare readings for the devices. Both devices demonstrated excellent reliability despite systematic bias between the two devices. Assessing tibial rotation with a goniometer results in greater values of motion when compared to using the smartphone compass app. Some of the differences in normative values may be the device or measurement technique utilized. These results show tibial rotation can be reliably assessed with either a smartphone or goniometer, however, the deviations between the two devices may require a scaling factor to be developed for between-instrument comparisons.
