The purpose of this study was to examine the effect of electrical stimulation in low- and high- frequency ranges on sensation and pressure-pain thresholds. A group of 54 subjects were randomly assigned to a 1 Hz electrical stimulation group (Group 1) and a 200 Hz electrical stimulation group (Group 2). Sensory threshold and pressure-pain threshold tests were performed before and after electrical stimulation. Electrical stimulation in the low- and high-frequency ranges increased both the sensory and pressure-pain thresholds. Of note, high-frequency electrical stimulation increased the thresholds of sensation and pressure-pain more than that noted with low-frequency electrical stimulation. The findings of this study showed that high-frequency electrical stimulation was more effective than low-frequency electrical stimulation in improving sensation and pressure-pain thresholds.
