Brazilian Infant Motor Development Norms and U.S. Comparison Using TIMP

Nadia Cristina Valentini's dataset establishes Brazilian age norms for infant motor development using the Test of Infant Motor Performance (TIMP). It contains data from 724 Brazilian infants from diverse regions, assessed and classified by medical risk, and compares trajectories with U.S. infants. The dataset was last updated on 2026-04-22.

Use Cases

• Establishing population-specific clinical cutoff scores based on the proposed Brazilian norms.
• Comparing motor development trajectories between Brazilian and U.S. infant populations.
• Investigating the impact of medical risk history on TIMP motor performance scores.
• Improving screening accuracy and referral decisions for motor delays in Brazilian infants.

Strengths

• Includes data from 724 Brazilian infants, providing a substantial sample for analysis.
• Infants are from diverse geographic regions within Brazil, which may improve generalizability.
• Data is classified into low-, moderate-, and high-risk groups based on medical history.
• Analysis includes Bayesian linear regression and discriminative power analysis.

Limitations

• Row count and column-level documentation are unknown, limiting suitability assessment.
• The dataset is very small at 35.1 KB, indicating limited scope or summary-level data.
• The primary file format is DOCX, which may require conversion for computational analysis.
