The motor quotient. A method for the early detection of motor delay

Area of Science:

• Pediatrics
• Developmental Pediatrics
• Motor Development

Background:

• Gross motor delay is a significant concern in pediatric development.
• Early identification of motor delays is crucial for effective intervention.

Purpose of the Study:

• To evaluate the efficacy of a motor quotient in predicting gross motor delay in infants.
• To assess the diagnostic accuracy of the motor quotient method.

Main Methods:

• Calculated a motor quotient by dividing the age of a child's best motor achievement by their chronological age.
• Applied the motor quotient to a cohort of 144 children aged 8 to 18 months.
• Determined sensitivity, specificity, and referral rates.

Main Results:

• The motor quotient demonstrated a sensitivity of 87% and a specificity of 89% in predicting gross motor delay.
• A quotient less than 50 was indicative of potential delay (e.g., walking at or after 24 months).
• Overreferral and underreferral rates were found to be 12%.

Conclusions:

• The motor quotient is a valuable tool for forecasting gross motor delay in young children.
• This ratio-based approach offers a promising method for early detection of motor developmental issues.
• The findings support the use of the motor quotient in clinical settings for pediatric motor assessments.
