Mobility performance and its sensory, psychomotor and musculoskeletal determinants from age 75 to age 80
Background and aims : Prospect i ve studies on the simultaneous effects of multiple determinants on objective ly assessed mobility are few . The aim of this study was to analyse mobility performance , its stability and sensory , psychomotor and musculoskeletal determinants in an older population from age 75 to age 80 . Methods : Sixty-three men and 121 women aged 75 participated at baseline and , five years later , in the follow-up phase of this population -based prospect i ve study .  Maximal walking speed and step-mounting height were assessed at baseline and follow-up . Maximal isometric knee extension strength , st and ing balance on force platform , reaction time , visual acuity and limitations in range of motion ( ROM ) of hips and knees were assessed at baseline . Structural equation modeling was used to analyse the associations . Results : The stability of mobility performance from baseline to the five-year follow-up was high ( coefficient 0.80 in men , 0.78 in women ) . In men , knee extension strength , st and ing balance , ROM limitations and visual acuity explained 69 % of the variation in mobility performance at baseline and , indirectly , 59 % of that variation at follow-up . Among women , knee extension strength , st and ing balance , visual acuity and reaction time explained 52 % of the variation of mobility performance at baseline and , indirectly , 30 % at the five-year follow-up . Conclusions : Results indicate that the predictive effects of sensory , psychomotor and musculoskeletal functions on mobility performance extend over five years in older people . In seeking to prevent mobility limitations , vision , reaction time and lower extremity ROM need to be targeted , in addition to muscle strength and balance
