    Background: There is a paucity of empirical research on motor asymmetry in healthy children using currently available assessments. Objective: This study sought to develop
    bilateral tests for quantitative and qualitative assessment of locomotor skills in typically developing children and assess their validity and reliability. Methods: A sample of 78 children (35 girls; 7.34±0.53 years) underwent testing using three newly constructed bilateral tests: side rolling, single leg skips and single leg hops. Results: Between subject reliability (Cronbach alpha: 0.97 to 0.98; 0.98 to 0.99; 0.98 to 0.99, respectively), within-subject reliability (Coefficient of Variation: 0.04 to 0.10; 0.05 to 0.11; 0.07 to 0.13, respectively), and between-rater reliability (Intraclass Correlation:0.81 to 0.92, 0.79 to 0.94, and 0.83 to 0.91, respectively), of all 3 tests were found to be very high. Further, considering laterality, the results indicate very high construct validity (explained variance by single-extracted factor ranged from 94.48 to 96.68, from 97.56 to 98.57 and 96.53 to 98.09, respectively). Conclusion: The results suggest that the newly constructed tests can be implemented as a reliable and valid tool for the assessment of bilateral locomotor skills in children.
