Figure 6From: Differential effects of tactile high- and low-frequency stimulation on tactile discrimination in human subjectsSpatial selectivity of t-LFS-induced effects. Percent changes in discrimination thresholds (n = 16) of group 4 of all fingers of the right hand (d1–d5), while tactile LFS was applied to the right index finger (d2) for a period of 20 min. In contrast to t-HFS, 20 minutes of t-LFS induced a significant decline in discrimination thresholds not only on d2, but also on d3 indicative for some transfer of plastic changes to other fingers.Back to article page
