Outline of Final Research Achievements

The present study examined the relationship between the risk of falling, diabetes mellitus (DM) and postural control deficits in older adults by means of step-tracking device that uses an infrared laser sensor. In results, fallers showed significantly slower response time in step initiation task with cognitive load than non-fallers. Furthermore, fallers with DM showed significantly prolonged response time than those without DM. Analysis of movement initiation with cognitive load during can expose the risk of falling in older adults with DM.
