Outline of Final Research Achievements

The ability to effectively adjust limb movements in response to unexpected visual feedback is an important skill that may help prevent falls. This study investigated age-related changes in the ability to perform online corrective adjustments in response to an unexpected visual target shift during upper limb reaching and lower limb stepping. Impaired reactive performance was observed in older adults with delayed corrective adjustments in both tasks. The latency for corrective adjustments was comparable between the tasks, and the use of handrails to minimize balance constraints during stepping did not shorten it. These results imply that the delay in corrective adjustments is not due to suppression of reactive response to minimize destabilizing effects on upright stability but rather is attributed to impaired reactive performance. Training intervention aimed at improving the reactive performance to unexpected perturbations would be effective for fall prevention.
