• Quick, valid and responsive outcome measure are critical for physical therapists
• The NIH’s Patient Reported Outcomes Measurement Information System (PROMIS) is a universal, 124 item, computer adapted system (CAT) that evaluates various health domains including physical function without a ceiling or floor effect.
• PROMIS demonstrates good convergent validity with the Health Assessment Questionnaire Disability Index (HAQ-DI) and Short-form 36 (SF-36) physical function subscale1 and also with ‘gold standard' International Knee Documentation Committee (IKDC) scale. PROMIS score can also predict poor outcomes at various follow-up lengths ranging from 3-52 weeks2.
• The modified physical performance test (mPPT) is a performance-based test containing several functional tasks and is used to assess physical frailty in older individuals3.
• Patient reported outcomes (PRO) require less time and equipment compared to performance based measures.
• Purpose: To evaluate the relationship between scores on mPPT and PROMIS. Additionally, to map-out the scoring system of the PROMIS, to allow therapists to utilize it’s T-score in clinical practice.
