Motor proficiency differences among students with intellectual disabilities, autism, and developmental disability

Area of Science:

• Developmental Neuroscience
• Pediatric Motor Development
• Disability Studies

Background:

• Intellectual disability, autism, and developmental disability share overlapping symptoms.
• Understanding motor proficiency differences is crucial for targeted interventions.
• Previous research highlights the need for detailed motor skill assessments in diverse developmental conditions.

Purpose of the Study:

• To investigate motor proficiency variations among students with intellectual disability, autism, and developmental disability.
• To compare motor skill performance across different severities of intellectual disability (borderline, mild, moderate).
• To identify specific motor deficits in students with autism and developmental disability.

Main Methods:

• Utilized the Bruininks-Oseretsky Test of Motor Proficiency, Second edition (BOT-2) for comprehensive motor skill assessment.
• Compared motor proficiency in 82 students aged 11–20 years with diagnosed conditions.
• Employed descriptive statistics, independent t-tests, and analysis of variance for data analysis.

Main Results:

• Students with moderate intellectual disabilities demonstrated significantly lower scores on most motor skills assessed by the BOT-2.
• Significant differences in motor proficiency were observed when comparing moderate intellectual disability to borderline intellectual disability, mild intellectual disability, and autism groups.
• Students with borderline intellectual disabilities, mild intellectual disabilities, and autism showed varying, but generally higher, motor proficiency compared to the moderate intellectual disability group.

Conclusions:

• Moderate intellectual disability is associated with pronounced motor skill deficits compared to other developmental conditions studied.
• Findings underscore the importance of tailored exercise interventions to enhance motor function and quality of life.
• This research provides a foundation for individualized support strategies for children with developmental disorders.
