How to Manage Your Pain

Personalize Your Therapy

First, select the pain mode (i.e., lower back or arm) and then choose the intensity level. The programs are interchangeable and effective for multiple body parts. (Read the complete instruction manual carefully to safely and correctly use this pain management unit).

How Should It Feel? When Is It Working?

Expect variations of tapping, tingling,massage-like sensations or even mild muscle contractions. Always start with low intensity and increase slowly. If the sensation feels uncomfortable, decrease the intensity and/or change the program. If the sensation becomes weaker or disappears, increase the intensity.

How Long Should You Use It?

Start with one 15 minute session. Always turn unit off with pads still on. Rate your pain to check your progress, 1 low to 10 high. Stop therapy session if pain has reduced or stopped.

What is TENS?

  • Transcutaneous Electronic Nerve Stimulation.
  • Used by Physical Therapists for more than 30 Years.
  • Blocks the pain message.
  • Triggers endorphins (natural pain killers).
  • Enhances blood circulation.

Customers say the product provides immediate pain relief. They say it helps with heel pain, lower back pain, and shoulders. Customers also say it's a better alternative to pain medication, as it blocks the pain messengers to the brain.

PM500 TENS Unit belt clip faulty
3 Stars
PM500 TENS Unit belt clip faulty
I purchased the PM500 unit on March 7, 2022 and began using it on the 11th. I used it every day multiple times and was very impressed with the unit. I incorporated the belt clip so I could be mobile while using it. I noticed on April 9th that the clear retainer was very loose. Upon inspection, I noticed that the two retainer tabs on one side were both missing! Looking closely at the end, I realized that both tabs had broken off! The photos clearly show this! I phoned Omron Customer Support today, April 14, to report this and to get a free replacement. The Support Rep, David, ordered me a new clip “1 time as a COURTESY!” Can you imagine this… a part that lasted just barely a month has to be replaced “as a Courtesy” when the design is flawed. The clear retainer is designed using a brittle plastic and will break from ordinary, everyday use. That part is under too much stress based upon the design and type of material used. Omron must reevaluate this design and correct this fault so customers are not “forced” to do what I did. While looking at the clip, the tabs on the opposite end of the retain broke. So, I drilled two small holes through the inside ends of the retainer, threaded 24 gauge wire through the holes and looped it through the slots in the clip body. Then I twisted the ends of the wires to tighten and secure the retainer ends where they are supposed to be. Last, I inserted the PM500 into its proper position so I can use the belt clip! I do believe that Omron needs to seriously take a look at the design of the belt clip as this is the weakest link in this otherwise very good TENS device. I am very happy with the device, but am sad that if I hadn’t Gerry rigged the clip, I would be forced to carry the device in a pocket.
