IF-4000 Dual Channel Interferential Unit

The IF-4000 Interferential Unit helps control pain and speeds the healing process by delivering small pulses of electrical current to an injury through electrodes that pass current through the skin and stimulate underlying nerves producing a mild, tingling sensation to provide relief from chronic and acute pain.

Interferential is used for very localized areas where deep current for pain control or increased circulation is needed.

I purchased this IF4000 and love it. Sadly I dropped it and then purchased a second unit. Intermittent use throughout the day has finally reduced my pain significantly. I still deal with extensive swelling.

Great Price for Effective Relief
This unit is very effective. My wife has had recurring hip pain and even our TENs unit was not providing lasting relief. She went to the chiropractor where he used an interferential stim unit. This provided an effective, lasting therapy to the sore hip area. We elected to search to see if there were affordable units available. TENSpro had the best price on home grade units, hands down. It was delivered sooner than originally expected in perfect condition. She has used it several times and told me that it works well and provides lasting relief.

This thing works great and helps get my muscles relaxed during the times I am away from the chiropractor.

Add Review IF 4000 Dual Channel Interferential Unit
This unit works great for my wife and I to relieve arthritis joint pain. 15 minutes two or three times a week is almost as effective as acupuncture with electrode but not as expensive.
