초록
The purpose of this study was to determine the effect of transcutaneous electricalnerve stimulation(TENS) on sympathetic tone in healthy subjects. Stimulation inthe conventional and burst modes was applied to the skin of the forearm overlyingthe median nerve. TENS was applied for 20 minutes at an intensity sufficient toproduce a perceptible though not uncomfortable sensation and no muscle contracionof the forearm musculature. The change in sympathetic tone was measured withskin temperature. Skin temperature was measured at the index finger and on thevolar surface of the forearm in the stimulated limb. The conventional and burstmodes did not change the skin temperature at any of the two measurement sites. We conclude that TENS, as applied in this study, does not influence sympathetictone. Further research is needed to assess the sympathetic effects of TENS onpatient groups, long term treatment and other modalities.
