摘要

Early detection of peripheral neuropathies in the upper extremities, which are often manifest as changes in tactile function, is of considerable interest. Such neuropathies may occur as a result of disease, or in occupations in which workers are exposed to neurotoxic agents, or to mechanical vibration.The tactile performance of the fingers is known to depend on neural activity in up to four populations of specialized nerve endings. These mechanoreceptor types are commonly described by their response to mechanical indentation of the skin surface (i.e. SAI-slowoly adapting, type I; SAII-slowly adapting, type II; FAI-fast adapting, type I, and FAII-fast adapting, type II) SAI receptor acuity primarily determines the resolution of the spatial features of a surface, such as ridges or edges, and the roughness of surfaces. These receptors respond to pressure. FAI and FAII receptor acuity is primarily responsible for information obtained from the motion of surfaces across the skin surface or; conversely, moving fingertips across surfaces. Such information is used to determine smoothness and texture, and to maintain an appropriate grip of objects (which is controlled by the detection of micro-slips). SAII receptors primarily signal skin stretch. Separate responses from SM, FM and FAII receptor populations can be determined psychophysically by using precisely defined measurement conditions and vibrotactile stimulation at different frequencies. In some circumstances, such as selective loss of receptor function, it may not be possible to obtain separate thresholds from each population.
