心理策略已被建议构成一个有前途的方法，以提高运动能力的健康受试者和患者。这种行为效应已被证明与运动前区神经活动的变化有关，不仅在运动执行期间，而且在执行运动想象或动作观察时。然而，这种心理任务的执行情况往往很难评估，特别是在患者中。在这里，我们使用了一种新的心理训练范式的基础上，串行预测任务（SPT），以激活运动前电路在没有运动任务。然后，我们测试了这种干预是否能改善运动相关的表现，如感觉运动转换。两组健康的年轻参与者接受了为期五天的单盲认知训练计划，并在训练前一天和训练后一天进行了四项不同的运动测试。一组（N=22）接受SPT训练，另一组（N=21）接受基于系列匹配样本任务的对照训练，结果显示SPT组在感觉运动计时任务中有显著改善，即手指敲击与视觉呈现的节奏同步，以及与接受控制训练的组相比，在感觉引导的指向任务中改善的视觉协调。然而，心理训练并没有表现出转移对运动能力的影响，在健康的受试者超出了训练的方式明显的非显着变化，在Jebsen-Taylor handfunctiontest.In总结，数据表明，心理训练的基础上的串行预测任务有效地从事感觉运动电路，从而提高运动行为。(C)2013爱思唯尔有限公司保留所有权利。
Mental strategies have been suggested to constitute a promising approach to improve motor abilities in both healthy subjects and patients. This behavioural effect has been shown to be associated with changes of neural activity in premotor areas, not only during movement execution, but also while performing motor imagery or action observation. However, how well such mental tasks are performed is often difficult to assess, especially in patients. We here used a novel mental training paradigm based on the serial prediction task (SPT) in order to activate premotor circuits in the absence of a motor task. We then tested whether this intervention improves motor-related performance such as sensorimotor transformation.Two groups of healthy young participants underwent a single-blinded five-day cognitive training schedule and were tested in four different motor tests on the day before and after training. One group (N=22) received the SPT-training and the other one (N=21) received a control training based on a serial match-to-sample task.The results revealed significant improvements of the SPT-group in a sensorimotor timing task, i.e. synchronization of finger tapping to a visually presented rhythm, as well as improved visuomotor coordination in a sensory-guided pointing task compared to the group that received the control training. However, mental training did not show transfer effects on motor abilities in healthy subjects beyond the trained modalities as evident by non-significant changes in the Jebsen-Taylor handfunctiontest.In summary, the data suggest that mental training based on the serial prediction task effectively engages sensorimotor circuits and thereby improves motor behaviour.
