PMID 32110165WHAT IT FOUND
The Brazilian Portuguese version of the Functional Mobility Assessment is clear to both wheelchair users and future therapists.
People understood the questions about their daily mobility tasks well enough to use the tool in practice.
Key findings
01Both users of mobility devices and occupational therapy students demonstrated good levels of understanding of the instrument's sentences.
02The cross-cultural adaptation process resulted in a version that is semantically, idiomatically, culturally, and conceptually equivalent to the original English instrument.

What it does not show
The study only checked if people understood the words on the page (face validity). It did not test if the tool actually measures what it claims to measure (reliability or validity). The sample size for the understanding test was small, with only 12 users and 12 students. Participants were not blinded to the study's purpose, which might have influenced how they rated their understanding.
The easy way to misread this
Do not assume this tool is proven to accurately measure mobility outcomes or predict patient progress. This study only showed that people understand the questions, not that the answers are scientifically valid.
