The "upper limb rotation test": Reliability and validity study of a new upper extremity physical performance test. (March 2020) - Decleve, Ph
Abstract: Objectives: The 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. Design: Reliability study and correlation study. Setting: Laboratory. Participants: 91 healthy adults participated to establish the reliability and validity of the ULRT. Main outcome measures: We 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. Results: Results 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. Conclusions: Results demonstrated good relative reliability and clinically acceptable absolute reliability values for the ULRT. Performances on the ULRT were moderately correlated with the PPTs. Highlights: High relative reliability values and clinically acceptable absolute reliablity values were found. The ULRT showed moderate correlations with the CKCUEST and SMBT. The ULRT is a physical performance test including a combination of OKC, CKC and a trunk rotation as well as 90°/90° shoulder position.
