Abstract
Background
Studies have shown benefits of exercise interventions on preferred and fast gait speed in healthy older adults, but the impact of a personalised rehabilitation program targeting a large cohort of non-disabled older-old adults has rarely been examined.
Aims
The purpose was to determine whether personalised intervention-related improvements in gait and mobility performance in older-old adults were dependent on cognitive status and/or history of falls.
Methods
Based on a pre-post design, 483 older-old persons (mean age: 83.3 ± 5.1 years) were followed during a personalised rehabilitation program over a period of 7 weeks, with twice-weekly sessions (45 min each). Gait speed in four conditions (preferred, fast, and under two dual-task conditions), static postural sway, Timed Up and Go test, Five Times Sit to Stand test, the ability to rise from the floor, and handgrip strength test were assessed.
Results
Using a pre-post analysis of covariance, a significant increase in preferred gait speed (+ 20.1%), fast gait speed (+ 15.8%), and dual-task speed while counting (+ 13.4%) was observed after the rehabilitation, regardless of the baseline cognitive status and fall history. Similar improvements in TUG and maximal handgrip force were observed, with a significant reduction of performance time (-19.5%) or an increase of handgrip strength (+ 6.2%).
Discussion
Results suggest the effectiveness of personalised intervention to improve a battery of physical performance measures in older-old adults, even for the frailest participants.
Conclusion
Implementing a personalised intervention for targeting the high-risk older-old adults in priority is critical regarding the clinically meaningful change in gait speed.
