Purpose: To obtain reference values for healthy participants performing the Functional Mobility Assessment (FMA). The FMA is a reliable and valid tool used to examine functional abilities subjectively and objectively in patients with lower-extremity sarcoma in all components of the International Classification of Functioning, Disability, and Health model (body function, activity, and participation).
Methods: Children, adolescents, and young adults who were healthy, representing a sample of convenience (n = 503; 260 females, age 10–21 years), participated in this study.
Results: Means and standard deviations for all participants: Timed Up and Down Stairs 6.18 ± 0.8 seconds, Timed Up and Go 3.78 ± 0.6 seconds, 9-minute run/walk 4161 ± 893 feet, and the FMA total 59 ± 3.
Conclusion: The reference values provided in this study will allow health care professionals to compare the functional abilities of children, adolescents, and young adults with lower extremity sarcoma to age- and gender-matched healthy peers when using the FMA.
