Introduction/Purpose: Patients with foot and ankle conditions have been shown to demonstrate improvement in their generic outcomes using the Patient Reported Outcome Measurement Information System (PROMIS). However, the responsiveness to change and the impact change may have on quality of life has not been explored following non-operative care with physical therapy. The effect size (ES) is an assessment of the magnitude of change while the impact of change in physical function can be assed with quality of life utility scores. Therefore, the purpose of this analysis was to investigate the responsiveness of the PROMIS physical function (PF) scale on changes in quality of life.
