Association Between Motor Skills and Sensory Profiles in Children With Typical and Atypical Development Aged 4 to 11 Years

Plain-language summary

Background and Justification Childhood developmental disorders, such as Autism Spectrum Disorder (ASD), Attention Deficit Hyperactivity Disorder (ADHD), and Developmental Coordination Disorder (DCD), pose significant challenges for children and their families. These disorders impact children's growth and learning, leading to difficulties in key areas such as language, communication, behavior, social interaction, and motor skills. Research in this area is limited, particularly regarding fine and gross motor skills in relation to sensory processing in children with these diagnoses. Hypothesis and Objectives There is an association between motor skills and sensory processing in children aged 4 to 11 years, depending on whether they have typical or atypical neurodevelopment, such as ASD, ADHD, and DCD. Main Objective: To evaluate the association between motor skills and sensory processing in children aged 4 to 11 years with either typical or atypical neurodevelopment (e.g., ASD, ADHD, and DCD). Secondary Objectives: To describe and compare motor skills among children aged 4 to 11 years with typical or atypical neurodevelopment, such as ASD, ADHD, and DCD. To describe and compare sensory processing among children aged 4 to 11 years with typical or atypical neurodevelopment, such as ASD, ADHD, and DCD. Methodology The study is a cross-sectional observational case-control study. Participants are users of the Child Development and Early Intervention Center (CDIAP) Tris Tras, Neuro Xics, or Criv in Vic. The sample will include 30 children as controls (typical neurodevelopment) and 10 children as cases (atypical neurodevelopment: ASD, ADHD, DCD). Children will be assessed using the Infant Motor Profile (IMP) to measure motor development and the Short Sensory Profile-2 (SSP-2) to evaluate sensory processing. Statistical Analysis Quantitative variables will be described using means and standard deviations, while categorical variables will be presented as frequencies and percentages. Statistical tests such as the Student's t-test will be used to compare means between two groups, ANOVA for comparisons among more than two groups, and the Chi-square test to analyze associations between categorical variables. Expected Results The study is expected to provide essential insights into the differences in motor development between children with typical and atypical neurodevelopment, as well as the relationship between biological and external factors and these differences. These findings could help improve clinical and educational interventions for these children by tailoring them to their specific needs, thereby enhancing their overall well-being and development. Ethical Considerations The study protocol will be submitted to the Research Ethics Committee (CER) of UVic-UCC, adhering to good clinical practice guidelines in accordance with the Declaration of Helsinki. Participants will be assigned a code to ensure data pseudonymization, with data securely stored on the Microsoft 365 server of UVic-UCC. Participants will have the right to withdraw from the study at any time, and personal data will be deleted once the study is completed. Researchers will ensure confidentiality as dictated by Organic Law 3/2018 of December 5 on the Protection of Personal Data and Guarantee of Digital Rights, Regulation (EU) 2016/679 of April 27, 2016, on data protection, and complementary regulations, as well as Organic Law 1/1982 of May 5 on the right to honor, personal and family privacy, and self-image.
