频率特异性振动刺激外周肌腱诱导肢体运动的错觉，这可能有助于恢复本体感觉信息的人与感觉运动障碍。这种潜在的应用可能受到受试者之间和受试者内部对这种错觉的易感性的变化的限制，这可能取决于各种因素。为了探讨刺激参数和参与者的利手对运动错觉的影响，我们用五种刺激频率（从40到120 Hz，步长为20 Hz）振动了一组右利手和左利手的人的肱二头肌的左右肌腱。我们发现，所有参与者都报告了肘部伸展的预期错觉，特别是在40和60 Hz之后。左撇子表现出较少的变化，在报告的错觉相比，右撇子在不同的刺激频率。此外，非优势臂的刺激引起了更生动的错觉，相对于优势臂的刺激，这种效果与参与者的惯用手无关。总的来说，我们的数据表明，刺激频率，利手和手臂优势影响肌腱振动运动错觉。结果进行了讨论，参考他们的相关性，在连接运动意识，改善目前的设备，脑或脊髓损伤后的运动能力恢复和开发假肢和虚拟体现系统。
Frequency-specific vibratory stimulation of peripheral tendons induces an illusion of limb movement that may be useful for restoring proprioceptive information in people with sensorimotor disability. This potential application may be limited by inter- and intra-subject variability in the susceptibility to such an illusion, which may depend on a variety of factors. To explore the influence of stimulation parameters and participants’ handedness on the movement illusion, we vibrated the right and left tendon of the biceps brachii in a group of right- and left-handed people with five stimulation frequencies (from 40 to 120 Hz in step of 20 Hz). We found that all participants reported the expected illusion of elbow extension, especially after 40 and 60 Hz. Left-handers exhibited less variability in reporting the illusion compared to right-handers across the different stimulation frequencies. Moreover, the stimulation of the non-dominant arm elicited a more vivid illusion with faster onset relative to the stimulation of the dominant arm, an effect that was independent from participants’ handedness. Overall, our data show that stimulation frequency, handedness and arm dominance influence the tendon vibration movement illusion. The results are discussed in reference to their relevance in linking motor awareness, improving current devices for motor ability recovery after brain or spinal damage and developing prosthetics and virtual embodiment systems.
