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.

Key Words: High frequency, Low frequency, Needle TENS, Pain threshold
