Abstract

BACKGROUND: Impaired hip range of motion has been related to increased injury risk in baseball players. However, no hip rotation range of motion (ROM) reliability studies have been performed in youth, which cannot be assumed to be comparable to adults. This study aimed to: 1) assess the inter- and intra-rater reliability of hip rotation passive ROM in youth baseball players; 2) calculate the standard error of measurement (SEM) and minimum clinically important difference (MCID). METHODS: Hip external (ER) and internal (IR) rotation were measured. Inter and intra-rater reliability were assessed through intraclass correlation coefficients (ICC) and 95% Confidence interval (95% CI), with SEM and..
