可移动的触觉刺激装置放于实验动物足底,可根据实验人员需要设定力的大小和力增大的速度等。
触觉测量套件( Von Frey )以每次增加直径0.05mm的细丝增加施力,直到受试动物的爪抽搐。
动态足底触觉计的新模式为:
一台可移动的触觉刺激装置,配备刺激丝和可调整角度的镜子;
实为一微电子处理单位,提供数字显示、内部数据存储、可用闪存导出数据、可外接打印机;
宽敞的实验操作平台;
模块化的动物笼,可自由组合3-12个隔间。
动态足底触觉仪是用以自动评估啮齿类动物跖面的“触觉感应”。它与电子触觉测量(Electronic Von Frey )和足底触觉测量(Plantar Von Frey )类似,不同之处在于它能记录持续时间和爪缩回时的作用力。

Impaired cutaneous sensation is usually first manifested in a loss of light touch detection. So “mechanical” stimulation has a long history of effective clinical use to diagnose pa-thologies of hyper- or hypo-aesthesia, brought about by drugs, neural pathology or experimental lesions, etc.
The Dynamic Plantar Aesthesiometer was developed to apply a reproducible light touch to the rodent plantar surface, and quantify the force which causes the animal to react by withdrawing the paw.
