开发有效的补充剂和康复受损的触觉和本体感觉是一项重大挑战。在临床实践中改善这些感觉的一种潜在方法是使用具有白色噪声的随机共振。虽然经皮电神经刺激（TENS）是一种简单的方法，但通过TENS的阈下噪声刺激对感觉神经阈值的影响目前尚不清楚。本研究旨在探讨阈下TENS是否能改变传入神经阈值。在阈下TENS和对照条件下，对21名健康志愿者的A-β、A-δ和C纤维的电流感知阈值（CPT）进行了评估。与A-β纤维的对照条件相比，发现阈下TENS具有较低的CPT值。在阈下TENS和对照组之间，A-δ和C纤维无显著差异。我们的研究结果表明，阈下TENS可能选择性地增强A-β纤维的功能。
Developing effective supplements and rehabilitation of the impaired tactile and proprioception sensation is a significant challenge. One potential method for improving these sensations in clinical practice is using stochastic resonance with white noise. While transcutaneous electrical nerve stimulation (TENS) is a simple method, the effect of subthreshold noise stimulation via TENS on sensory nerve thresholds is currently unknown. This study aimed to investigate whether subthreshold TENS can alter afferent nerve thresholds. The electric current perception thresholds (CPT) of A-beta, A-delta, and C fibers were assessed in 21 healthy volunteers during both subthreshold TENS and control conditions. Subthreshold TENS was found to have lower CPT values compared to the control condition for A-beta fibers. No significant differences were observed between subthreshold TENS and control for A-delta and C fibers. Our findings indicated that subthreshold TENS might selectively enhance the function of A-beta fibers.
