Orthotic Research Initiative for Outcomes aNalysis (ORION I): predictors of PROMIS PF for stroke survivors seeking orthotic intervention.

Ankle-foot orthoses (AFOs) are used to improve physical performance measures of physical function (PF) post-stroke; however, the perception of improved PF of this population has not been described. The purpose of this study was to identify the predictors of self-reported PF of individuals seeking orthotic intervention post-stroke. A retrospective analysis of 237 patients at a nationwide orthotic services provider in the United States was conducted to characterize PF using the Patient-Reported Outcome Measures Information System®. A backward stepwise multiple regression was conducted to identify demographic characteristics predictive of self-reported PF. The mean T-score of PF of the sample was 30.8 ( These results improve understanding of the factors that contribute to impaired self-reported PF of stroke survivors in need of AFO intervention.Implications for rehabilitationAnkle-foot orthoses (AFOs) are often used to improve physical performance measures of physical performance (PF) during stroke rehabilitation.Our data indicate that the self-reported PF of AFO users is severely impaired.Level of assistance, time since ankle and foot problems began, and living assistance status are important clinical characteristics to consider when planning AFO intervention for this population.
