Movement control process can be considered to take place on at least two different levels: a high, more cognitive level and a low, sensorimotor level. On a high level processing a motor command is planned accordingly to the desired goal and the sensory afference, mainly proprioception, is used to determine the necessary adjustments in order to minimize any discrepancy between predicted and executed action. On a lower level processing, the proprioceptive feedback later employed in high level regulations, is generated by Ia sensory fibers positioned in muscle main proprioceptors: muscle spindles. By entraining the activity of these spindle fibers through 80Hz vibration of triceps distal tendon, we show the intriguing possibility of inducing kinematics adjustments due to negative feedback corrections, during a lifting task.
一个较高的、更具认知性的层面和一个较低的、感觉运动层面。在较高层面的处理中，根据期望目标规划运动指令，并利用感觉传入信息，主要是本体感觉，来确定必要的调整，以尽量减少预测动作与执行动作之间的差异。在较低层面的处理中，稍后用于较高层面调节的本体感觉反馈，是由位于肌肉主要本体感受器（肌梭）中的Ia感觉纤维产生的。通过对肱三头肌远端肌腱进行80赫兹的振动来带动这些梭形纤维的活动，我们展示了在举升任务中由于负反馈校正而诱发运动学调整的有趣可能性。
