Article Snippet: In this study, answers were grouped into 3 categories: improving (patient scored ‘somewhat improved’, ‘much improved’, or ‘very much improved’); stable (patient scored ‘no change’); or declining (patient scored ‘somewhat worse’, ‘much worse’, or ‘very much worse’). (v) PROMIS® Physical Function short form 20a [ , ]: (PROMIS PF): This score is obtained after the patient completes a questionnaire with 20 questions on physical function, which the patient can score from unable to do (1) to be able to do without any difficulties or limitations (5).
