Résumé : | Background Changes in sternocleidomastoid (SCM) muscle cross-sectional area (CSA) and volume may contribute to neck-related concussion symptoms and whiplash-associated disorders. Magnetic resonance imaging (MRI) data on healthy SCM morphology can provide information that may lead to targeted treatment protocols. Objectives To examine sex-related differences in MRI-based SCM CSA, SCM volume and neck area in healthy young adults, to analyze associations between measurements and participant variables and to assess inter-rater reliability for measurement quantification. Design Cross-sectional study. Methods 13 males and 14 females underwent MRI scans. Slices obtained from C3?C7 were analyzed by three raters. SCM CSA at C4, total SCM volume from C3?C7 and neck area at C4 were quantified. Measurements were calculated as absolute and normalized values by body mass. Multivariable regression was used to analyze associations between normalized measurement values and participant variables. Inter-rater reliability was determined using intraclass correlation coefficients (ICC). Results Females had significantly lower normalized overall average SCM CSA (mean difference 1.3 mm2/kg (95% CI 0.4?2.2, p = 0.006) and total SCM volume (mean difference 140.8 mm3/kg (95% CI 66.1?215.5, p |
