Comparative StudyThe effect of conventional transcutaneous electrical nerve stimulation on somatosensory evoked potentials.
Transcutaneous electrical nerve stimulation (TENS) is an electrotherapeutic modality used for analgesia. We planned to demonstrate selective stimulation of large diameter fibers with conventional type TENS by way of somatosensory evoked potentials (SEP). ⋯ SEP and finger-wrist segment sensory nerve conduction amplitudes were significantly decreased compared to pre-TENS values during 5, 10, and 15 minutes of TENS application (p < 0.05). These results reflect the selective stimulation of large diameter afferent fibers of conventional type TENS.
