Timed Floor to Stand-Natural: Reference Data for School Age Children

Purpose: To collect reference data for the Timed Floor to Stand-Natural (TFTS-N) on a large, diverse sample of school children who are typically developing, taking into account age, sex, and body mass index (BMI). Methods: Five physical therapists administered the TFTS-N on a sample of convenience of 1476 school children who were typically developing, aged 5 to 14 years (male = 637, female = 839), using previously tested, standardized reliable procedures. Results: The average time ranged from 7.91 +/- 1.65 seconds to 8.98 +/- 1.62 seconds; 8 year-old students were the quickest and the 13-year-old students were the slowest. The mean difference between males and females was clinically negligible at 0.38 seconds. Post hoc analyses revealed no significant differences among BMI categories. Conclusions: Reference data for the TFTS-N test are now available. Neither sex nor BMI affects the timing of the task in this age range.
