Validation of the Functional Activity Scoring Tool (FAST): a novel pictorial scale for assessing function in patients with knee osteoarthritis in primary care.

ABSTRACT:

Objective

Patient-reported outcome measures (PROMs) are crucial for assessing functional ability in patients with knee osteoarthritis. However, existing PROMs have limitations, particularly for individuals with low literacy or non-native English speakers. The Functional Activity Scoring Tool (FAST) was developed as a pictorial-based PROM to address these issues. This study evaluated the validity, reliability and responsiveness of the FAST compared with the Patient-Specific Functional Scale (PSFS) and Knee Injury and Osteoarthritis Outcome Score (KOOS) in patients with knee osteoarthritis.

Design

A multicentre prospective cohort study.

Setting

This study occurred from December 2022 to December 2023 across four public outpatient physiotherapy clinics in Singapore.
