VALERO, Camila et al. Foot rotation asymmetry in Down syndrome and the relationship with crawling and walking onset: a cross-sectional study. J. Hum. Growth Dev. [online]. 2021, vol.31, n.2, pp. 247-256. ISSN 0104-1282.

INTRODUCTION: Down syndrome individuals have different gait patterns, which include specific characteristics such as foot rotation asymmetryOBJECTIVE: The aim of this study was to analyze the relationship between this asymmetry and the hands-and-knees crawling pattern before gait acquisition in Down syndrome children, as well as the possible association of this gait to gender, ethnicity, comorbidities, physiotherapy, and occupational therapy interventionsMETHODS: In this cross-sectional study, 361 children with or without foot rotation asymmetry were selected. An online questionnaire was administered to the parents or guardians of those childrenRESULTS: Hands-and-knees crawling decreased the prevalence of foot rotation asymmetry in Down syndrome children. The longer it took for walking onset, the higher the prevalence of this asymmetry. Indeed, for each month of delay, there was a 7% increase in prevalence. There was a significant relationship between orthopedic alterations in knees or flat feet and foot rotation asymmetry. There was no significance related to gender, ethnicity, other comorbidities, physiotherapy, or occupational therapy interventionsCONCLUSION: The findings in this study revealed that foot rotation asymmetry might be related to the acquisition of motor skills, hands-and-knees crawling and the walking onset
