Introduction/Purpose: It is unclear whether patients attending physical therapy, post-op or for conservative care, achieve clinically important differences (CID) on the patient reported outcome information system (PROMIS) scales. Key PROMIS outcomes physical function (PF) and pain interference (PI) match well with treatments provided in physical therapy. Physical therapy may also influence depression (Dep). Documentation of PROMIS outcomes associated with physical therapy are useful to help set patient expectations. The purpose of this analysis was to document expected PROMIS PF, PI, and Dep outcomes after physical therapy for foot and ankle diagnoses by 1) reporting average improvement and 2) examining whether severity of symptoms (PROMIS Scales) at the start of physical therapy are associated with a 0.5 standard deviation (CID) improvement at the end of therapy.
