伸手是允许人类与环境互动的基本技能。一些研究旨在使用各种方法表征到达行为。本文提供了经颅磁刺激的开源应用,以评估人类在达到任务执行期间的皮质脊髓兴奋状态。

这种方法将灵活的行为到达范式与经颅磁刺激肌电图相结合,所有这些都来自一台计算机。这很重要,因为它简化了现有方法。这种技术的主要优点是它是公开可用的,并且在行为任务和 TMS 参数方面提供了灵活性。这种设置可以很容易地适应临床人群的使用,因为它是多功能和可移动的。该方法为行为伸展和运动适应过程中的皮质脊髓兴奋性和肌肉活动提供了独特的见解。将大型图形输入板平放在桌面上。使用可调节的 80-20 铝制框架将任务显示器与平板电脑上方 6 到 8 英寸平行,屏幕朝上。接下来,将受试者放在面向平板电脑的舒适椅子上,并确保膝盖弯曲至 90 度
