摘要

记录功能成像过程中的表现是一种标准程序,用于控制顺应性、感觉运动和认知需求。就运动任务而言,精确度、力度和频率对功能激活的程度有重大影响。心理调查中使用问卷来控制认知需求,而心理生理记录则用于记录身体反应。对于纵向干预研究而言,最重要的是实施细致的前后控制和平衡,以准确评估随时间推移而发生的变化。顺应性的任何变化都可能带来额外的不受控制的变量,从而妨碍对功能磁共振成像(fMRI)相关变化的解释。本综述介绍了在功能成像方法中控制和平衡表现的策略,以记录康复研究中的神经可塑性。这些策略不仅包括运动相关方面,如精确度、速度和力量,还包括计时方面,如运动周期的开始和停止。此外,它还讨论了利用视觉反馈调节和控制运动方面的策略,以及在实验调节过程中控制生理变化的策略。虽然这些措施需要额外的关注,往往比研究的神经成像部分要求更高,但它们对于相关的解释和发表 fMRI 研究至关重要。

Performance control during longitudinal activation fMRI studies.

The documentation of performance during functional imaging represents a standard procedure employed to control for compliance, sensorimotor, and cognitive demands. In the case of motor tasks, preciseness, force, and frequency have a significant impact on the magnitude of functional activation. Questionnaires are used in psychological investigations to control for cognitive demand, while psychophysiological documentation is employed to record bodily responses. For longitudinal intervention studies, it is of utmost importance to implement meticulous pre- and post-performance controls and balance to accurately assess changes over time. Any changes in compliance may introduce additional uncontrolled variables, which can hinder the interpretation of functional magnetic resonance imaging (fMRI)-related changes. This narrative review presents strategies for controlling and balancing performance in functional imaging approaches to document neuroplasticity in rehabilitative studies. These strategies include not only motor-related aspects, such as precision, velocity, and force, but also timing aspects, such as the start and stop of movement periods. In addition, it discusses strategies for the modulation and control of movement aspects with visual feedback, as well as for the control of physiological changes during experimental modulation. Although these measures require additional care, which is often more demanding than the neuroimaging part of the study, they are crucial for a relevant interpretation and publication of fMRI studies.

期刊介绍: Frontiers in Human Neuroscience is a first-tier electronic journal devoted to understanding the brain mechanisms supporting cognitive and social behavior in humans, and how these mechanisms might be altered in disease states. The last 25 years have seen an explosive growth in both the methods and the theoretical constructs available to study the human brain. Advances in electrophysiological, neuroimaging, neuropsychological, psychophysical, neuropharmacological and computational approaches have provided key insights into the mechanisms of a broad range of human behaviors in both health and disease. Work in human neuroscience ranges from the cognitive domain, including areas such as memory, attention, language and perception to the social domain, with this last subject addressing topics, such as interpersonal interactions, social discourse and emotional regulation. How these processes unfold during development, mature in adulthood and often decline in aging, and how they are altered in a host of developmental, neurological and psychiatric disorders, has become increasingly amenable to human neuroscience research approaches. Work in human neuroscience has influenced many areas of inquiry ranging from social and cognitive psychology to economics, law and public policy. Accordingly, our journal will provide a forum for human research spanning all areas of human cognitive, social, developmental and translational neuroscience using any research approach.
