Primary Objective

This study evaluated whether a meditation practice incorporating mobile neurofeedback (mNF) offers any advantage over a more traditional form of focused attention (FA) meditation in managing persistent symptoms after traumatic brain injury (TBI) (clinicaltrials.gov NCT02615535).

Research Design

Pilot randomized clinical trial, exploring feasibility of mNF in TBI.

Methods and Procedures

Participants included adults with chronic mood and/or cognitive complaints following mild-moderate TBI. Subjects practiced either FA (n = 10) or mNF (n = 10) meditation 12 minutes daily for 6 weeks. Pre-post intervention difference on the Neurobehavioral Symptom Inventory (NSI) was the primary outcome variable. Secondary outcomes included the Beck Anxiety Inventory (BAI), Beck Depression Inventory-II (BDI-II), amongst other scales and neurocognitive tests.

Main Outcomes and Results

No significant pre-post between-group differences were found on the NSI (p = .838) nor other assessments. In an exploratory analysis combining FA and mNF data, meditation was associated with significant improvements on the NSI (p = .04), BAI (p = .012) and BDI (p = .037).

Conclusions

Meditating with neurofeedback does not appear to provide an advantage over meditating on one’s own for chronic post-TBI symptoms. Further research on home-based meditation following TBI, whether self-directed or technologically facilitated, is warranted.

轻度中度颅脑损伤后持续注意力的集中注意力冥想与移动神经反馈的冥想比较：一项前瞻性研究。

主要目标

这项研究评估了结合移动神经反馈（mNF）的冥想练习是否比传统形式的集中注意力（FA）冥想在管理创伤性脑损伤（TBI）后持续症状方面有任何优势（clinicaltrials.gov NCT02615535）。

研究设计

试行随机临床试验，探索mNF在TBI中的可行性。

方法与程序

参与者包括轻度中度TBI后患有慢性情绪和/或认知障碍的成年人。受试者每天12分钟练习FA（n = 10）或mNF（n = 10），持续6周。主要的结果变量是神经行为症状量表（NSI）的事后干预前差异。次要结果包括贝克焦虑量表（BAI），贝克抑郁量表II（BDI-II），以及其他量表和神经认知测验。

主要结果和结果

NSI（p = .838）或其他评估均未发现组间差异显着（p = .838）。在结合FA和mNF数据的探索性分析中，冥想与NSI（p = .04），BAI（p = .012）和BDI（p = .037）的显着改善相关。

结论

与神经沉思相比，用神经反馈进行冥想似乎并没有比单独冥想TBI后慢性症状更为有利。无论是自我指导还是技术上的推动，都需要对TBI之后的家庭冥想进行进一步的研究。
