There was no statistically significant difference between the TENS and interferential current groups (P > 0.05); a difference was only found between these groups and the controls (P < 0.0001). Conclusion: There was no difference between TENS and interferential current for chronic low back pain treatment.

Which is Better TENS or IFC?

TENS delivers low-frequency current across the surface of the skin, while IFC delivers a higher frequency current that penetrates deeper into the tissue with less discomfort. So, if IFC is stronger, why doesn't it hurt?

What is different between TENS and IFT?

Whereas TENS Units delivers periodic electric pulses to stimulate surface nerves and block the pain signal, IFT Physiotherapy Equipment transmits a continuous stimulation deep into the affected tissue thereby blocking the pain signals and reducing swelling and inflammation which causes pain.
