Age expansion of the thirty-second walk test norms for children

Pediatr Phys Ther. 2009 Fall;21(3):235-43. doi: 10.1097/PEP.0b013e3181b170d4.

Abstract

Purpose: The purposes of this study were to expand age ranges for a previously published normative database (n = 227) on the 30-second walk test, describe changes with age, explore contributions of subject characteristics, and verify previous data.

Methods: Children (n = 302; age, 5-17 years) from 4 urban schools were tested for distance walked in 30 seconds. Age, height, right lower extremity length, weight, sex, and race/ethnicity were recorded.

Results: Distance walked increased from 5 to 10 years of age, decreased slightly at age 11 years, followed by a more gradual decrease from 12 to 17 years. A significant difference in distance walked was found across ages. Right leg length, age, and weight explained 11.5% of the variance in walk distance.

Conclusion: A percentile chart of the pooled data (previous and current, n = 529) should facilitate the use of the 30-second walk test when examining children for mobility limitations.
