While cognitive interventions in mild cognitive impairment (MCI) show positive effects on cognitive performance, physical activity appear to slow down cognitive decline, suggesting a relationship between both factors. However, previous combined programs that have shown significant improvement in cognitive function in MCI have typically trained cognition and physical functioning separately.
Objective:
This project aimed at evaluating two group interventions combining the stimulation of physical and cognitive domains in individuals with MCI: Simultaneous stimulation of physical and cognitive skills in comparison to a standardized training, which stimulates cognitive and physical functions separately.
Methods:
The study was designed as a randomized controlled trial. The first group was trained on the SpeedCourt® system while the second group completed the standardized Fitfor100 program. Training was completed by a total of 39 subjects with diagnosed MCI as determined by the CERAD (SpeedCourt®: 24 subjects, Fitfor100:15 individuals).
Results:
There were significant improvements of physical factors (e.g., hand strength and balance) in both groups. Improvement in the CERAD total score allowed for a post interventional classification of all participants into non-MCI and MCI. This effect persisted over a period of three months. Both forms of intervention were found to be effective in improving various cognitive functions which persisted for a period of three months.
Conclusion:
Both evaluated non-pharmacological, multicomponent interventions, which combined physical and cognitive training in a social setting showed improvement of cognitive functions leading to a persistent classification of former MCI patients in non-MCI patients.
