Small point here but anytime after activity might behoove you to put on cold pack and also compress to hold swelling down. Elevate when you can.

Tens is delivering you at best 150 pulses per second, ( this simply means unit goes off and on 150 times ) and tens provides no carryover/residual pain relief, ie. if you turn it off the pain comes back. Interferential has 8,000+ pulse or off/on cycles per second, so with a 30 minute treatment you should be able to be pain free for some time period. The time period tends to increase over time with multiple treatments. You may start off with carryover pain relief for an hour, several hours, or days progressing to only doing interferential treatment say weekly.

My guess is in your situation your back pain is the secondary source of pain, not the primary due to the knee replacement surgery, the posturing due to pain, and now the pain is spreading.

You also might want to consider anytime you put tens on your back to also do so with some form of moist heat on top of the electrodes while unit running. Do not use moist heat where swelling is an issue until you’ve used cold first.

If can help then give a call at 800-937-3993 if you live in US/Canada or post back and will comment. Thanks.

P.S. negative charges of electricity actually repel most fluids that aggregate and cause swelling but both interferential and tens are not constant negative but vacilliate between positive and negative. Sometimes larger electrodes with either of these will help reduce the swelling too but not major point to spend time thinking about.

I think what you are referring to is a cooling cuff to hold down the inflammation of soft tissue following surgery. Think it’s a “cryogenic cuff” or cooling machine that basically replaces ice packs.

Generally if you are getting surgery the “hospital discharge planner” or same day surgery planner has a list of home health agencies that can supply or through their contracts they will have one delivered to you.

Hope I got this right and generally the surgeon/hospital/clinic includes this in total fee package and makes sure insurance covers.

Hopefully this will help you.
