Test-retest reliability and convergent validity of the Ruffier Index in children under 12 years old

ConclusionThe findings of this study indicate that the RI shows a “poor” test-retest reliability and a convergent validity ranging from “acceptable” to “poor”, when administered to children under 12 years of age.RésuméObjectif pour identifier la fiabilité test-retest et la validité convergente du test de Ruffier sur des enfants.MéthodeUn total de 352 participants (âge moyen 10,14 ± 1,02 ans; 47,2% filles) ont effectué le test de Ruffier deux fois, avec un intervalle d’une semaine entre les deux évaluations, afin d́identifier sa fiabilité test-retest. La consommation maximale d’oxygène estimée avec le test de Course-Navette a été utilisée pour déterminer sa validité convergente.RésultatsLe test de Ruffier a dénoté une « mauvaise » fiabilité test-retest (ICC = 0.43–0.64). La relation entre le test de Ruffier et la consommation maximale d’oxygène estimée a été « acceptable » pour le test (r = −0,37; P = 0,003) et le retest (r = −0,32; P = 0,01) sur les filles, tandis que sur les garçons cette relation a été « médiocre » (r = −0,12; P = 0,04 et r ...

CONCLUSION: Although PS being a clinical diagnosis, this study indicated that in patients whom PS was not suspected at the initial examination, 8.2% of them were finally diagnosed after MRI evaluations. Performing specific pelvic sequences as an adjunct to routine lumbar MRI can salvage underdiagnosed patients with PS and facilitate early detection of this pathological condition.
