The “upper limb rotation test”: Reliability and validity study of a new upper extremity physical performance test

Abstract

ObjectivesThe primary purpose was to evaluate the reliability of the Upper Limb Rotation Test (ULRT). The secondary objective was to evaluate the relationship between the ULRT and two PPTs (SMBT and CKCUEST), trunk rotation range of motion (SRT) and shoulder rotational isometric strength. DesignReliability study and correlation study. SettingLaboratory. Participants91 healthy adults participated to establish the reliability and validity of the ULRT. Main outcome measuresWe used a two-session measurement design to evaluate the reliability of the ULRT. The SMBT, CKCUEST, SAC and the SRT were performed to determine relationships with the ULRT. ResultsResults showed good reliability. The SEM 95 and the MDC95 showed clinically acceptable absolute reliability values for the ULRT. A moderate correlation was found between the ULRT and CKCUEST scores. A moderate correlation was found between ULRT and SMBT scores. ConclusionsResults demonstrated good relative reliability and clinically acceptable absolute reliability values for the ULRT. Performances on the ULRT were moderately correlated with the PPTs.
