Short-Term Suppression of Somatosensory Evoked Potentials and Perceived Sensations in Healthy Subjects Following TENS

Transcutaneous electrical nerve stimulation (TENS) has been reported to alleviate pain in chronic patients. Currently, there is limited knowledge how TENS affects can cause cortical neuromodulation and lead modulation of non-painful painful sensations. Our aim was therefore investigate the effect conventional, high-frequency on activation perceived sensations healthy subjects. We recorded somatosensory evoked potentials (SEPs) following (100 Hz) 40 subjects (sham intervention group). The examined up an hour after phase, results revealed significant inhibition. found that magnitude N100, P200 waves, theta alpha band power significantly suppressed intervention. These changes were associated with a simultaneous reduction intensity size area where sensation felt. Although phantom limb relief previously inhibition activity, efficacy present induce such should be verified future clinical trial.
