Brain computer interfaces (BCIs) allow for controlling devices through modulation of sensorimotor rhythms (SMR), yet a profound number of users is unable to achieve sufficient accuracy. Here, we investigated if visuo-motor coordination (VMC) training or Jacobsen's progressive muscle relaxation (PMR) prior to BCI use would increase later performance compared to a control group who performed a reading task (CG). Running the study in two different BCI-labs, we achieved a joint sample size of N=154 naïve participants. No significant effect of either intervention (VMC, PMR, control) was found on resulting BCI performance. Relaxation level and visuo-motor performance were associated with later BCI performance in one BCI-lab but not in the other. These mixed results do not indicate a strong potential of VMC or PMR for boosting performance. Yet further research with different training parameters or experimental designs is needed to complete the picture.
脑机接口 (BCI) 允许通过调制感觉运动节律 (SMR) 来控制设备，然而，大量用户无法达到足够的准确性。在这里，我们研究了在使用 BCI 之前进行视动协调 (VMC) 训练或雅各布森渐进性肌肉放松 (PMR) 是否会比进行阅读任务的对照组 (CG) 提高后期的表现。在两个不同的 BCI 实验室中进行研究，我们获得了 154 名未经训练的参与者的联合样本量。干预措施（VMC、PMR、对照组）对 BCI 性能没有显著影响。在一个 BCI 实验室中，放松水平和视动表现与后期 BCI 性能相关，但在另一个实验室中则没有。这些混合结果表明，VMC 或 PMR 没有很强的提高性能的潜力。然而，需要进行不同的训练参数或实验设计的进一步研究，以完善这一结果。
