Development and performance of PROWalk: a functional mobility person-reported outcome measure based on the PROMIS® adult physical function item bank

Compared with broader PROMIS Physical Function short forms, PROWalk targets mobility-specific activities relevant to gait and balance. It demonstrated significant improvements in perceived functional mobility over time and strong temporal stability, supporting its use for standardized group-level comparisons. PROWalk appears to be a valid, telehealth-compatible measure for capturing self-reported functional mobility in individuals with sensory neuropathy and may address limitations of more individualized assessment tools.
