“…However, they compared brain activity during a DT with the brain activity during the motor ST only, therefore we lack information about the activation during the cognitive ST (Holtzer, Mahoney et al 2011;Doi, Makizako et al 2013;Ohsugi, Ohgi et al 2013;Meester, Al-Yahya et al 2014;Mirelman, Maidan et al 2014). All studies involved lower limb movements in terms of walking or standing (Holtzer, Mahoney et al 2011;Doi, Makizako et al 2013;Ohsugi, Ohgi et al 2013;Meester, Al-Yahya et al 2014;Mirelman, Maidan et al 2014).…”

Cognitive-motor interference refers to dual-tasking (DT) interference (DTi) occurring when the simultaneous performance of a cognitive and a motor task leads to a percentage change in one or both tasks. Several theories exist to explain DTi in humans: the capacity-sharing, the bottleneck and the cross-talk theories. Numerous studies investigating whether a specific brain locus is associated with cognitive-motor DTi have been conducted, but not systematically reviewed. We aimed to review the evidences on brain activity associated with the cognitive-motor DT, in order to better understand the neurological basis of the CMi. Results were reported according to the technique used to assess brain activity. Twenty-three articles met the inclusion criteria. Out of them, nine studies used functional magnetic resonance imaging to show an additive, under-additive, over- additive, or a mixed activation pattern of the brain. Seven studies used near-infrared spectroscopy, and seven neurophysiological instruments. Yet a specific DT locus in the brain cannot be concluded from the overall current literature. Future studies are warranted to overcome the shortcomings identified.

“…In addition, the combination of exercise and brain training, the dual-task is considered to be more effective than doing the single task. Previous studies utilizing brain training have reported cortical activation during dual-task interference [23] and increased activation of the prefrontal cortex (PFC) [24,25]. In addition, dual-task had wider effective range compared to single-task.…”

Introduction: As to addiction, it is evident that high palatability (addictive) substances, such as drinking alcohol or smoking, all occur due to emptiness, psychologically the same mechanism, with emotional and mental factors playing a big role. Therefore, we have, focused on mental soundness, and researched the relationships between mental health level/stress and cognition/judgement. Furthermore, through a brain training game employing rhythmical exercises and touching, we have clarified whether this will mitigate mental stress and affect cognitive functions, too. Methods: Subject: We recruited 100 people living in the area by public information in Kashihara City. It was a three month intervention, comparing the results with controls and interventions. The evaluation scale is as follows.

“…This is evident from studies demonstrating increased cortical activity during the performance of walking tasks that require adaptability (Clark, Rose, Ring, & Porges, 2014; Koenraadt, Roelofsen, Duysens, & Keijsers, 2014; Meester, Al-Yahya, Dawes, Martin-Fagg, & Pinon, 2014). The complexity of the environment and the demands placed on the individual while walking on uneven terrain will likely result in heightened attentional demand and potential interference with control processes for any other simultaneous motor or cognitive task (Clark, 2015).…”

BACKGROUND One third of individuals after stroke report an inability to walk in the community. Community mobility requires walking adaptability—the ability to adjust one’s stepping pattern to meet environmental demands and task goals. Walking on uneven terrain (e.g. grass, gravel) has unique requirements and is a critical component of walking adaptability that has not been investigated in the post-stroke population. OBJECTIVE To summarize current knowledge of biomechanical and neuromuscular modifications during uneven terrain negotiation in healthy individuals and discuss implications of post-stroke impairments. METHODS Review of eleven studies, identified through a search of relevant literature on PubMed and CINAHL. RESULTS On uneven terrain, healthy adults demonstrate numerous gait modifications including a lowered center of mass, increased muscle co-contraction during stance and exaggerated or increased toe clearance during swing. After stroke, changes in muscle activity and limb coordination will likely result in difficulty or inability performing these modifications that healthy adults use to maintain stability and safety when walking on uneven terrain. CONCLUSIONS Studies of biomechanical and neuromuscular control of walking on uneven terrain are needed to quantify mobility limitations in adults post-stroke. Such investigations will contribute to the understanding of mobility impairments after stroke and the design of critically important intervention strategies.
