“…This is consistent with previous findings using other neurophsysiological techniques (fMRI, e.g., Porro, Cettolo, Francescato, & Baraldi, 2000; EEG, e.g. Stecklow, Infantosi, & Cagy, 2010). Taken together, this evidence provides further support for a central mechanism to explain movement imagery's effects rather than the now outdated peripheral psychoneuromuscular theories.…”

Sport and exercise psychologists provide some interventions for clients based on limited direct evidence and partial understanding of the mechanisms that underpin their efficacy. The authors review a recent technique, transcranial magnetic stimulation (TMS), which offers a tested procedure for investigating cortical activity during observation and imagery processes. They provide a detailed description of the TMS protocol and highlight some of the key studies that inform sport and exercise psychology research. Finally, the authors offer some thoughts on the direct application to practice.

“…Para uma melhor compreensão das diferentes estratégias utilizadas durante a simulação mental de movimentos, diversas abordagens têm sido utilizadas, desde paradigmas com pacientes com lesões cerebrais 26 ou com sujeitos saudáveis 25,[28][29][30][31][32]34 . No entanto, os achados são similares entre os diversos estudos.…”

Rev Neurocienc 2013;21(4):604-619 revisão 604 RESUMO Introdução. A imagética motora (IM) consiste na evocação do plano motor de uma dada ação sem que haja a execução do movimento. Objetivo. Realizar uma revisão e análise crítica sobre a IM, discutindo as características neurofisiológicas, as diferenças entre as estratégias de simulação e sua aplicação clínica no contexto da reabilitação de pacientes pós-Acidente Vascular Cerebral (AVC). Método. Busca de artigos indexados pelas bases ISI e Medline, publicados entre 1980 e 2012, nos idiomas inglês, português e espanhol. Discussão. A IM é capaz de levar a ativações cerebrais, fisiológicas e comportamentais semelhantes às ocorridas durante a execução motora. Entretanto, a IM pode ser realizada utilizando duas possíveis estratégias, a cinestésica e a visual, e cada uma delas provoca distintos padrões de ativação cortical. Observou-se que o treinamento com a IM é capaz de gerar ganhos funcionais em pacientes pós-AVC. No entanto, não foi possível padronizar a utilização do protocolo mais adequado, visto que ainda não há um consenso quanto à frequência, duração, a estratégia de IM e a fase da doença mais apropriada para sua aplicação. Conclusão. Apesar dos avanços, ainda há necessidade de mais estudos a fim de determinar as diretrizes para a utilização da IM na reabilitação motora e seus benefícios a longo prazo. ABSTRACTIntroduction. Motor imagery (MI) consists in the evocation of a motor plan of a given action without motor output. Objective. To perform a review and critical analyses about MI, discussing its neurophysiological characteristics, differences between the strategies of simulation and the clinical application in the context of rehabilitation of post-stroke patients. Method. Search of studies indexed by ISI and Medline databases, published between 1980 and 2012, in English, Spanish or Portuguese. Discussion. MI can promote similar brain, physiological and behavioral activations as during the execution of motor actions. However, MI can be performed using two possible strategies, visual and kinesthetic, and each of them causes different patterns of cortical activation. It was also observed that the training with MI can improve performance in post-stroke patients. However, it was not possible to standardize the use of the more appropriate protocol, since there is still no consensus on the frequency, duration, strategy of MI and stage of the disease is most appropriate for its application. Conclusions. Despite the advances, there is still a need of more studies to determine the guidelines for mental simulation in the motor rehabilitation and its long-term benefits.

“…As a method of functional brain imaging for brain wave testing, many different innovative methods of radiological examination including the electroencephalogram, positron emission tomography, magnetic resonance imaging, functional magnetic resonance imaging, and single-photon emission computerized tomography have been used, and these methods can be used to confirm the brain’s functional changes by comparison with normal brains 5 ) . Compared with other experimental brain imaging methods, brain wave measurement is a commonly used as a noninvasive method for analyzing the changes in brain functions directly within a short period of time, and providing a variety of useful information with data from a short examination 6 ) . It is also an electronic neurophysiological experiment method that can be used to investigate the brain’s functional status in real-time while focusing on a specific assignment.…”

The effect of neurofeedback on a brain wave and visual perception in stroke: a randomized control trial

et al. 2015

[Purpose] This study investigated a brain wave and visual perception changes in stroke subjects using neurofeedback (NFB) training. [Subjects] Twenty-seven stroke subjects were randomly allocated to the NFB (n = 13) group and the control group (n=14). [Methods] Two expert therapists provided the NFB and CON groups with traditional rehabilitation therapy in 30 thirst-minute sessions over the course of 6 weeks. NFB training was provided only to the NFB group. The CON group received traditional rehabilitation therapy only. Before and after the 6-week intervention, a brain wave test and motor free visual perception test (MVPT) were performed. [Results] Both groups showed significant differences in their relative beta wave values and attention concentration quotients. Moreover, the NFB group showed a significant difference in MVPT visual discrimination, form constancy, visual memory, visual closure, spatial relation, raw score, and processing time. [Conclusion] This study demonstrated that NFB training is more effective for increasing concentration and visual perception changes than traditional rehabilitation. In further studies, detailed and diverse investigations should be performed considering the number and characteristics of subjects, and the NFB training period.
