躯体感觉系统的个体感受器系统包括肌肉感受器、关节感受器和机械感受器。本研究旨在研究站立在泡沫表面上如何改变与足部这些个体感受器系统的功能相关的多个生物力学变量。这些受体的机械输入，包括足底压力的变化，踝关节旋转和速度，以及腓肠肌和胫骨前肌的姿势反应，测量在突然脚趾向上运动的支持基地。比较了三种不同表面条件（即分别为硬表面、1“”和2 "“泡沫）的这些测量值。一组15名健康的年轻男性受试者参加了这项研究。结果表明，在平台运动的早期阶段，站立在泡沫（或软表面）上会影响足部关节感受器和皮肤机械感受器的输入，但不会影响肌肉感受器。此外，中，长潜伏期反应的腿肌肉出现显着延迟时，站在泡沫，而腓肠肌的短潜伏期反应是不变的。
The individual receptor systems of the somatosensory system include the muscle receptors, joint receptors and mechanoreceptors. This study was intended to investigate how standing on foam surfaces would change the multiple biomechanical variables associated with the functions of each of these individual receptor systems in the foot. Mechanical inputs to these receptors, including the changes in plantar pressures, ankle joint rotation and velocity, as well as postural responses from the gastrocnemius and tibialis anterior muscles, were measured during an abrupt toes-up movement of the supporting base. These measurements were compared for three different surface conditions (i.e. hard surface, 1 '', and 2 '' foams, respectively). A group of 15 healthy, young male subjects participated in the study. The results showed that standing on foam (or soft surface) would affect the inputs to both joint receptors and cutaneous mechanoreceptors in the foot, but not the muscle receptors in the early phase of the platform movement. Furthermore, the medium and long latency responses in the leg muscles appeared to be delayed significantly when standing on foam, while the short latency response in the gastrocnemius muscle was unchanged.
