Fiabilidad intraexaminador e interexaminador de Clinometer para medir el rango de movimiento en pacientes con artrosis de cadera

Abstract

ObjectiveTo evaluate the test–retest and inter-rater reliability of the application Clinometer for measuring the hip range of motion (ROM) in patients with hip osteoarthritis and its correlation with the universal goniometer. MethodsA blinded repeated measured was carried out with 35 patients with hip osteoarthritis. Hip internal rotation, external rotation, flexion and extension ROM were measured using Clinometer app by 2 independents raters. The intraclass correlation coefficient was used to calculate the test–retest reliability and inter-rater reliability. The standard error measurement and minimal detectable change were also calculated. The Pearson's correlation coefficient was used to correlate the app with the universal goniometer. ResultsClinometer application achieved excellent test–retest reliability (intraclass correlation coefficient: 0.82-0.96) and inter-rater reliability (intraclass correlation coefficient: 0.81-0.95) in all the ROMs assessed. The correlation analysis with the universal goniometer showed strong correlation values (r>0.70) in all the ROMs assessed. ConclusionClinometer application presented excellent test–retest reliability and inter-rater reliability for the measurement of hip ROM in patients with hip osteoarthritis. The smartphone application showed a strong correlation compared to universal goniometer.
