Abstract:
OBJECTIVE: This study was conducted to compare the effects of low frequency needle transcutaneous electrical nerve stimulation (TENS) and high frequency needle TENS on experimental pain threshold. METHOD: Twenty two healthy adult subjects were assigned randomly to a low-TENS group or to a high-TENS group. Experimental pain threshold at forearm was determined with pain threshold of electrical simulation using surface electrode and needle electrode. RESULTS: Low-TENS group showed that pain relief was developed after 10 minutes and persisted 3 hours after treatment cessation. Low-TENS group showed a significant increase in experimental pain threshold opposing to high TENS group. CONCLUSION: This results suggest that effect of low frequency needle TENS therapy is better and longer than high frequency needle TENS therapy.
