Intrarater reliability and agreement of a modified Closed Kinetic Chain Upper Extremity Stability Test.
Abstract
OBJECTIVES\nTo assess the reliability of a modified procedure for Closed Kinetic Chain Upper Extremity Stability Test (CKCUEST).\n\n\nDESIGN\nIntra- and intersession reliability and agreement; SETTING: Clinical.\n\n\nPARTICIPANTS\nTwenty-seven asymptomatic athletes.\n\n\nMAIN OUTCOME MEASURES\nThe modifications (m-CKCUEST) in CKCUEST procedure consisted in hand spacing at one half arm-span, and to complete the three regular-series of 15\u202fs exertion by performing a fourth 1-min series during which the number of touches was counted every 15\u202fs. The intra- and intersession reliability and agreement were assessed for the numbers of touches in order to produce two outcome measures: m-CKCUEST score and muscular endurance index.\n\n\nRESULTS\nThe most reliable m-CKCUEST score was obtained when averaging the numbers of touches of the second and third sets (Intraclass Coefficient of Correlation(3,k); ICC\u202f=\u202f0.92). Good reliability was found for muscular endurance index computed when dividing the one-half number of touches counted during the last 30\u202fs of 1-min set, by the m-CKCUEST score calculated above (ICC\u202f=\u202f0.86).\n\n\nCONCLUSIONS\nThe m-CKCUEST allowed the production of two reliable outcome measures, which assessed the upper limb stability and the muscular endurance. Such outcomes may be used in a follow-up to assess performance or rehabilitation level.
