Action observation and motor imagery are valuable strategies for motor learning. Their simultaneous use (AOMI) increases neural activity, with related benefits for motor learning, compared to the two strategies alone. In this study, we explored how sonification influences AOMI. Twenty-five participants completed a practice block based on AOMI, motor imagery and physical execution of the same action. Participants were divided into two groups: An experimental group that practiced with sonification during AOMI (sAOMI), and a control group, which did not receive any extrinsic feedback. Corticospinal excitability at rest and during action observation and AOMI was assessed before and after practice, with and without sonification sound, to test the development of an audiomotor association. The practice block increased corticospinal excitability in all testing conditions, but sonification did not affect this. In addition, we found no differences in action observation and AOMI, irrespective of sonification. These results suggest that, at least for simple tasks, sonification of AOMI does not influence corticospinal excitability; In these conditions, sonification may have acted as a distractor. Future studies should further explore the relationship between task complexity, value of auditory information and action, to establish whether sAOMI is a valuable for motor learning.

动作观察和运动想象是运动学习的宝贵策略。与单独使用这两种策略相比，它们的同时使用 (AOMI) 会增加神经活动，并为运动学习带来相关益处。在这项研究中，我们探讨了超声处理如何影响 AOMI。25 名参与者完成了基于 AOMI、运动意象和同一动作的物理执行的练习块。参与者被分为两组：一组在 AOMI (sAOMI) 期间进行超声练习，另一组没有收到任何外部反馈。在练习前后评估休息和动作观察和 AOMI 时的皮质脊髓兴奋性，无论有无声波，以测试听觉运动协会的发展。在所有测试条件下，练习块都增加了皮质脊髓的兴奋性，但超声处理并没有影响到这一点。此外，我们发现在动作观察和 AOMI 方面没有差异，与声波无关。这些结果表明，至少对于简单的任务，AOMI 的超声处理不会影响皮质脊髓兴奋性；在这些情况下，声波处理可能会起到干扰作用。未来的研究应进一步探索任务复杂性、听觉信息价值和行动之间的关系，以确定 sAOMI 是否对运动学习有价值。AOMI 的超声处理不影响皮质脊髓兴奋性；在这些情况下，声波处理可能会起到干扰作用。未来的研究应进一步探索任务复杂性、听觉信息价值和行动之间的关系，以确定 sAOMI 是否对运动学习有价值。AOMI 的超声处理不影响皮质脊髓兴奋性；在这些情况下，声波处理可能会起到干扰作用。未来的研究应进一步探索任务复杂性、听觉信息价值和行动之间的关系，以确定 sAOMI 是否对运动学习有价值。
