抽象的。先前对人类和猴子的大纤维皮肤机械感受器的研究表明，它们对垂直皮肤压痕和施力速率敏感。尽管一些研究检查了皮肤对拉伸的传入反应，但相对较少的研究检查了切向施加到皮肤的剪切力的神经和感知相关性。本研究评估了人类受试者调节施加到食指远端垫的不同水平的切向力的能力。受试者被指示选择自己的震级估计尺度。以 0.10 N/s、0.15 N/s 或 0.30 N/s 的速率随机施加 0.15 至 0.70 N 的七个力水平。切向力是用涂有粘合剂的光滑金属刮刀产生的，以确保对下面的皮肤施加剪切力而不会打滑。还使用相同的程序以法向力产生皮肤压痕。结果表明，大多数人类受试者能够缩放施加在食指尖上的切向力和法向力的不同大小。力的变化率不影响所施加力的感知。这些结果凸显了切向力在触觉感知中的潜在重要作用。
Abstract. Prior research on large-fibre skin mechanoreceptors in humans and monkeys has demonstrated their sensitivity to perpendicular skin indentation and to the rate of force application. Although some studies have examined skin afferent responses to stretch, relatively few investigations have examined the neural and perceptual correlates of shear forces applied tangentially to the skin. The present study assessed the ability of human subjects to scale different levels of tangential force applied to the distal pad of the index finger. Subjects were instructed to choose their own magnitude estimation scale. Seven force levels ranging from 0.15 to 0.70 N were delivered randomly at rates of 0.10 N/s, 0.15 N/s or 0.30 N/s. Tangential forces were produced with a smooth metal spatula coated with an adhesive to insure a shear force on the underlying skin without slip. The same procedures were also used to generate skin indentation with normal forces. The results showed that most human subjects were able to scale different magnitudes of both tangential and normal forces applied to the tip of the index finger. The rate of force change did not influence the perception of the applied forces. These results highlight the potentially important role of tangential forces in haptic perception.
