EEG-based neurofeedback uses mental behaviours (MB) to enable voluntary self-modulation of brain activity, and has potential to relieve central neuropathic pain (CNP) after a spinal cord injury (SCI). This study aimed to understand neurofeedback learning and the relationship between MB and neurofeedback success. Twenty-five non-CNP participants and ten CNP participants received neurofeedback training (reinforcing 9–12 Hz; suppressing 4–8 Hz and 20–30 Hz) on four visits. Participants were interviewed about the MB they used after each visit. Questionnaires examined the following factors: self-efficacy, locus of control, motivation, and workload of neurofeedback. MB were grouped into mental strategies (a goal-directed mental action) and affect (emotional experience during neurofeedback). Successful non-CNP participants significantly used more imagination-related MS and reported more negative affect compared to successful CNP participants. However, no mental strategy was clearly associated with neurofeedback success. There was some association between the lack of success and negative affect. Self-efficacy was moderately correlated with neurofeedback success (r = < 0.587, p = < 0.020), whereas locus of control, motivation, and workload had low, non-significant correlations (r < 0.300, p > 0.05). Affect may be more important than mental strategies for a successful neurofeedback performance. Self-efficacy was associated with neurofeedback success, suggesting that increasing confidence in one’s neurofeedback abilities may improve neurofeedback performance.

基于脑电图的神经反馈使用心理行为 (MB) 来实现大脑活动的自愿自我调节，并有可能缓解脊髓损伤 (SCI) 后的中枢神经性疼痛 (CNP)。本研究旨在了解神经反馈学习以及 MB 与神经反馈成功之间的关系。25 名非 CNP 参与者和 10 名 CNP 参与者在四次访问中接受了神经反馈训练（加强 9-12 Hz；抑制 4-8 Hz 和 20-30 Hz）。参与者在每次访问后都接受了关于他们使用的 MB 的采访。问卷调查了以下因素：自我效能、控制点、动机和神经反馈的工作量。MB分为心理策略（目标导向的心理行为）和情感（神经反馈期间的情绪体验）。与成功的 CNP 参与者相比，成功的非 CNP 参与者显着使用了更多与想象相关的 MS，并报告了更多的负面影响。然而，没有任何心理策略与神经反馈的成功明显相关。缺乏成功与负面影响之间存在某种关联。自我效能与神经反馈成功呈中度相关（r = < 0.587，p = < 0.020），而控制点、动机和工作量的相关性较低且不显着（r < 0.300，p > 0.05）。对于成功的神经反馈表现，情感可能比心理策略更重要。自我效能与神经反馈的成功有关，这表明增加对一个人的神经反馈能力的信心可能会改善神经反馈的表现。
