INTRA- AND INTER-RATER RELIABILITY FOR LIMB LENGTH MEASUREMENT AND TRIAL ERROR ASSESSMENT OF THE UPPER QUARTER Y-BALANCE TEST IN HEALTHY ADULTS

摘要

BackgroundThere has been an increased emphasis placed on outcome measures in healthcare recently. This emphasis, coupled with a limited amount of clinically meaningful upper extremity closed-kinetic chain performance-based measures, has led to the development of the Upper Quarter Y-Balance Test (YBT-UQ). Current literature has reported the established reliability of the test-retest and inter-rater reliabilities of the YBT-UQ, but not the intra-rater and inter-rater reliability of limb length (LL) measurement and trial error assessment (assessing whether a subject committed an error during the trial thus negating the results of that trial). These components are important to the output of the measure and therefore need to be examined.
