Can physical and cognitive training based on episodic memory be combined in a new protocol for daily training?

BACKGROUND: Cognitive training (CT) is defined as guided practice on a set of standard tasks designed to stimulate particular cognitive functions. Recent studies have shown that physical exercise is beneficial for cognitive activity in older adults and patients with degenerative diseases. AIMS: The main objective of the present study is to create a new cognitive tool able to provide training for cognitive functions that take advantage of the physical activity involved in the execution of the task. A study concerning the application of a new CT tool for episodic memory is presented and divided in two parts. The first one aims at developing a new sensorized device, called SmartTapestry, for physical and cognitive training. The second part aims at understanding its technical viability and level of sensitivity in stimulating the same cognitive domain covered by the standardized tests, despite the introduction of the physical activity variable. METHODS: The SmartTapestry device was tested with a total of 53 subjects, 29 healthy subjects and 24 subjects suffering from mild cognitive impairment. RESULTS AND DISCUSSIONS: The results show a good correlation between the two approaches (p < 0.005), suggesting that SmartTapestry can stimulate the same cognitive functions of traditional cognitive tasks, with the addition of physical exercise. CONCLUSIONS: The results of this study may be useful in designing ecological and combined cognitive-physical tools, which can be used daily at home, reducing the presence of clinical staff, to train at the same time the brain and the body so as to improve the cognitive treatments efficacy.

Foot Inertial Sensing for Combined Cognitive-Motor Exercise of the Sustained Attention Domain.

OBJECTIVE: In the past decade, cognitive training tools have been used to improve brain functioning, and some have been applied to cognitive decline in dementia. Recently, research studies have demonstrated that aerobic exercise could play an important restorative role toward cognitive impairments. Therefore, the main objective of this paper is to present the innovative use of the SmartWalk tool, which combines aerobic exercise and cognitive protocols traditionally used to stimulate cognitive function. METHODS: The primary goal of this study to demonstrate if our tool is correlated with traditional computerized test in stimulating the cognitive system similarly, despite the fact that SmartWalk adds a supplementary physical load on the task. The SmartWalk tool was tested with a total of 49 subjects-29 healthy subjects and 20 subjects with Mild Cognitive Impairments. The participants were asked to perform both the tests to fulfil the proposed goal. RESULTS: The results obtained considering the overall population show a good and significant (p < 0.05) correlation for the "correct," "error," and "omitted" scores (r = 0.54, r = 0.34, and r = 0.39, respectively). CONCLUSION: The results suggest a good correlation between the two approaches with the advantage of adding aerobic exercise to the traditional cognitive task. SIGNIFICANCE: The results of this study may be useful in designing ecological and combined cognitive-physical tool to personalize interventions and delay the onset of cognitive disorders like dementia.
