Rated 5 out of 5 by from works great... Great buy for the money i bought this at Walgreens for 79.00 .. for my shoulder/back (I have severe chronic back pain)...Last week I had 6 trigger point injections in my shoulder and now it is day 6 and the pain is unbearable... tpi is the worst thing ever as far as my handling the post injection pain. Today i bought the Omron tens unit and have used it 3 times...It works great... QUICK relief and easy to place pads... My only issue is that is says you can only use it 3 times a day and that is NOT enough... i use mode 8 (massage) in the tens w/o heat. gotta find out if more than 3 times is dangerous...

Rated 5 out of 5 by from Fast relief for post-surgical ankle I had ankle surgery 5 - 6 weeks ago. I am back to full weight bearing and trying to start working out. However, the pain and swelling has been tough. I tried my husband's TENS unit then decided to pick one up on my way into work the next day. I spent the extra for the heat pain pro and glad I did! I used it two different ways on my ankle ( so 2 sessions) and got relief quickly. I was walking without pain for hours. Using it again better than any anti-inflammatory or pain med

Rated 1 out of 5 by from Wire shorted in less than 48 hours. The wire to the pads developed a short on only the second day of use. I called the company and was told that unlike the other models, they did not have replacement wires/pads. I could try to find the receipt, mail the device back at my own expense and they would consider whether it was a defect under the warranty. That could take several weeks during which I would not have a functioning machine. I bought a less expensive brand that happens to direct four pads and so has been providing better pain relief than the heat pain pro tens unit did.

Rated 3 out of 5 by from Extra Cords are not available for purchase I purchased this unit a couple of days ago. I love the unit but I am disappointed that I cannot buy extra cords so that someone else can use the unit besides me as the instructions say not to share the gel pads. The battery is not replaceable according to a customer service representative that I talked to. My first set of gell pads did not last for 30 uses but I was reading on the web that I should clean the skin areas with rubbing alcohol before using pads like these to prevent the oil from the skin from leaching into the gel.

Rated 4 out of 5 by from 1st Treatment gave relief My husband and I both used last night after receiving yesterday. Husband used on his elbow twice and said it felt good. Would have liked more heat. I used on my knee twice that I recently hurt, swells after working out and can't bend like it did before. I noticed immediate flexibility improved. Husband didn't like not being able to see the display sitting in dark room watching tv. Would be great if display lit up a little. We will continue to use and I'll submit a future review to show progress.

How does TENS and HEAT work?
Physical therapists have been using the combination of heat and TENS for decades. The HEAT warms the muscle for soothing comfort, and TENS provides pain relief. TENS therapy suggests that electrical stimulation therapy may work in several ways:
1. The gentle electrical pulses move through the skin to nearby nerves to block or shut out the pain message from ever reaching the brain from the source of the pain.
2. The gentle electrical pulses increase the production of the body’s natural pain killer, such as endorphins.
3. Furthermore, it is thought that the electrical stimulation improves blood circulation as well. Muscles contract and relax with the flow of the electrical stimulation. With repeated contracting and relaxing, the blood flows in and out and the blood circulation is improved.

Get Started With Your Therapy
1. Pad Placement: Clean and dry affected area so it is free of all lotions/oils/sweat. The PAD with GEL should be applied only to normal, intact, clean, healthy skin that is not experiencing any swelling or inflammation.
2. Customize Your Therapy: All therapies automatically stop after 30 minutes. To change therapies, turn main unit off, then on again.
– Combo 1 Therapy delivers 15 minutes of heat followed by 15 minutes of any one of the TENS modes for a total of 30 minutes of therapy.
– Combo 2 Therapy delivers heat and TENS alternately for a total of 30 minutes of therapy.
– TENS Therapy provides only TENS for 30 minutes.
3. Pick Heat Setting: Heat setting applies only to Combo 1 or Combo 2 Therapies. Actual temperature may vary due to skin condition, age, location of pain and more.
– Low temperature – 107 degrees Fahrenheit.
– High temperature – 110 degrees Fahrenheit.
4. Pick 1 of 9 Modes: Combo 1 and Combo 2 Therapies begin with “Heat” and you will see a red glow. When TENS is in use, the red glow will disappear.
– Mode 1: Tap
– Mode 2: Knead
– Mode 3: Rub
– Mode 4: Arm
– Mode 5: Lower Back
– Mode 6: Leg
– Mode 7: Foot
– Mode 8: Joint
– Mode 9: Shoulder
5. Adjust The Level of Intensity (1 Low – 20 High): Start at the lowest intensity level and slowly increase it by pushing the up or down arrow button. You should feel a gentle pulsing sensation. When the main unit is in “TENS” stimulation, you can adjust the power level of intensity.
