摘要：

The conduction velocities of A beta-, A delta- and C-fibers of a peripheral nerve of the upper limb in normal subjects were measured by a combination of conventional electric stimulation, painful CO2 laser stimulation and non-painful CO2 laser stimulation of a tiny skin surface area, respectively. The values obtained were 69.1 +/- 7.4 m/s, 10.6 +/- 2.1 and 1.2 +/- 0.2 m/s, respectively. These findings demonstrated that the combined methods are useful for experimental a nd clin ica I exploration of the physiological function and pathophysiological role of A beta-, A delta- and C-fibers of a given peripheral nerve.
