The effect of transcutaneous electrical nerve stimulation (TENS) on pain was studied in 13 patients, 7 men and 6 women, in Rehabilitation Medicine. Electrical stimulation was done for 20 minutes through an electrode on pain regions using a constant current stimulator with a frequency of 100Hz.Clinical effect of TENS was excellent (5.8%), good (52.9%), fair (29.4%) and poor (11.9%). Pain score after treatment decreased to 5.7±2.8 (Mean±S. D.) from the preoperative score of 10. TENS on peripheral pain was effective but that on central pain was not effective. Somatosensory evoked potentials (pain related late positive component: P250) were measured before and after TENS. Amplitude of P 250 decreased in patients with good effect after treatment of TENS.We concluded that transcutaneous electrical stimulation was simple, non-invasive, safe and effective treatment to different pains in Rehabilitaion Medicine.
