Balance Tests in Pre-Adolescent Children: Retest Reliability, Construct Validity, and Relative Ability

Area of Science:

• Pediatric motor development
• Biomechanical analysis of balance
• Childhood physical assessment

Background:

• Childhood balance is crucial for physical development, involving automatic postural adjustments.
• Understanding balance characteristics and sex differences is vital for targeted interventions.
• Assessing balance requires reliable and valid measurement tools.

Purpose of the Study:

• To determine the reliability and concurrent validity of balance and motor tests in healthy 11-year-olds.
• To compare the balance abilities of boys and girls.
• To evaluate the impact of vision on balance performance.

Main Methods:

• Evaluated measurement characteristics (reliability, validity) of selected balance and motor tests.
• Assessed balance performance in 11-year-old children under eyes-open and eyes-closed conditions.
• Utilized statistical analysis to compare performance between sexes and identify correlations between tests.

Main Results:

• High interrater reliability (0.810–0.910) and confirmed construct validity for balance tests.
• Girls demonstrated significantly better performance than boys in multiple balance components, especially with eyes open and closed.
• Low correlations between most balance tests suggest they measure distinct aspects of balance ability.

Conclusions:

• The study confirms the reliability and validity of the assessed balance tests for 11-year-olds.
• Significant sex-based differences in balance performance were observed, with girls showing superior abilities.
• A single balance test is insufficient to comprehensively assess a child's overall balance capacity.
