Concordancia entre 2 sistemas de medición de movilidad articular de rodilla en sujetos jóvenes sanos: estudio transversal

Abstract

IntroductionThe assessment of joint mobility arches is one of the essential elements to determine the onset and progression in physiotherapeutic treatments. ObjectiveTo analyze the concordance of the universal goniometer and the digital goniometer to measure the movements of flexion and extension of the knee bilaterally, in healthy young subjects. MethodsA descriptive, analytical cross-sectional study involved 180 healthy young people, randomly selected and voluntarily, with a mean age of 21.7 years, who were measured in the knee flexo-extension movement passively. The intraclass correlation coefficient (ICC) according to absolute, was used to measure the degree of agreement between the quantitative assessments made. There was an abnormality in the distribution of data from knee flexion–extension measurements, so comparisons were made with the median of the data. ResultsA very good agreement was found in the use of the universal goniometer and the digital goniometer, for knee movements: right flexion ICC 0.956, right extension ICC 0.936, left flexion ICC 0.933, and for left extension ICC 0.953. ConclusionsThe universal goniometer and the digital goniometer obtained a very good correlation in the measurement of knee flexion and extension.
