Association of balance measures and perception of fall risk on gait speed: a multiple regression analysis.

ABSTRACT

Gait speed, commonly modified to adapt to the balance and stability challenges of aging, is related to measures of balance and mobility. This study investigated associations between age, Berg Balance Scale, Activities-Specific Balance Confidence (ABC) Scale, One Question Fear of Falling (1QFOF), and gait speed in adults using regression analysis. Results suggested an interaction between 1QFOF and ABC scores. An expanded five-variable model explained 49% of gait speed variance. Age, ABC, and 1QFOF-ABC interactions were significantly associated with gait speed. Regression analysis is useful in investigating associations between performance variables and function. Continued research needs to identify optimal variable combinations and improve prediction of function.
