OBJECTIVE: To describe main motor disorders detected in children with autism spectrum disorder (ASD) and analyze associated clinical variables.
PATIENTS AND METHOD: A cross-sectional observatio nal study of 96 children with ASD, median age 4 years (range, 3-9), 32.3% girls, and 18.8% preterm. Children were evaluated at the UC-CHRISTUS Clinical Hospital Neurodevelopmental Unit for three years. We analyzed the relationship between motor signs (stereotypies, delayed gait, and hypo/hyper tonia) and spoken language at 4 years of age.
RESULTS: 63.5% of children presented a motor disorder, 33.3% had hand or body motor stereotypies at the time of the evaluation, and 28.1% had delayed gait (> 16 months of corrected gestational age). These children had a higher frequency of absence of spoken language at four years of age (OR = 9.36; 95% CI = 2.67-32.78) than patients without delayed gait. 40.6% of children presented alterations in muscle tone during the first two years of life (32.3% generalized hypotonia and 8.3% generalized hypertonia). A history of generalized hypotonia increases the chance of presenting delayed gait (OR = 2.65; 95% CI = 1.08-6.48) and motor stereo typies (OR = 2.63; 95% CI = 1.04-6.65).
CONCLUSIONS: Children with ASD usually develop motor disorders that may precede the diagnosis of the condition. In ASD, infant hypotonia may predict the occurrence of other motor disorders, and delayed gait was associated with spoken language absence in preschool age.
