This study provides a new 15-item LEFS with four response categories for clinicians and researchers to measure function in foot and ankle patients in a relevant way. Implications for rehabilitation Assessing foot and ankle function and rehabilitation effectiveness is of high importance. The Lower Extremity Functional Scale (LEFS) is a widely used 20-item patient-reported outcome instrument with five response categories. The Finnish LEFS was revised to better fit into the Rasch model. The new LEFS with 15 items and four response categories for foot and ankle patients is a psychometrically sound, meaningful, and operable instrument.

Our study shows that the Finnish version of the PRWE is reliable, valid, and responsive for the evaluation of pain and disability after distal radius fracture.
