Validation of Self-Reported Gait Speed and Grip Strength Measures With Objective Measures in Older Adults With Mild Frailty in England

Background

Clinical research often relies on in-person assessments, which can limit participation among frailer older adults who have difficulty attending clinical settings. Developing valid self-reported alternatives could improve inclusivity. We aimed to validate self-reported gait speed and grip strength against objective measures in adults aged ≥ 65 with mild frailty participating in the HomeHealth trial.
