Background: The major objective of this study was to examine whether differences occur in the joint angles of the major lower limb joints while walking in youth with multiple sclerosis (YwMS) compared to age-gender-matched healthy youngsters. Methods: Gait analysis was collected using a six-camera Cartesian Optoelectronic Dynamic Anthropometer (CODA) 3D motion analysis system. To determine the gait normality in the YwMS group, we compared our results to reference gait data from normal youngsters. Gait data was divided according to gender and age subgroups (8–14, 15–18 years old). Results: The total sample included 26 YwMS (12 girls, 14 boys), 11 in the 8–14 age subgroup, and 15 in the 15–18 age subgroup. The mean expanded disability status scale score was 1.3 (S.D=1.0), indicating minimal disability. The total range of hip motion was significantly less in the YwMS group aged 15–18 (both genders) compared with the normative values. Additionally, the maximum flexion in the knee joint during gait was significantly less in boys in the 15 to 18 age subgroup (p<0.001). No differences were found in the hip and knee joint angles in the 8–14 age subgroup. Conclusions: YwMS experience modifications in their gait pattern compared with age-gender-matched healthy youngsters. The MS teenagers demonstrated less range of movement in the hip joints and walked slower at a decreased pace than the healthy teenagers. By tracking gait patterns, healthcare providers can identify subtle changes that might facilitate timely interventions to prevent further mobility impairment in this young population.
