Once your body gets accustomed to that one particular sensation, it will eventually stop responding to it. On the other hand, our TENS & EMS produces various kinds of massage sensations randomly so that your muscles are always in for the best result possible every time you use it.

5. How to take care of the replacement electrode massage pads?

Before applying massage pads, clean your skin first before you apply pads in pair. If the pads become dry, apply few drops of tap water or hand sanitizer to moisture pads. If the pads are too sticky due to local humidity, you may put the sealed pads in the cool fridge to last longer.Never leave the pads unattended, disclosure to the direct sunlight. 

Depending on the frequency and time of use, the electrode pads may shorten the life of use, normally it can last from one month to several months. If you find the pads lose their adhesiveness, you can simply apply a small amount of moisture to make them adhesive again, or if the pads are worn out, then it is time to replace the pads. Replacement electrode pads can be ordered in the accessory tab under shop. To change the pads, just unsnap the button on the back of the pads and snap on the new pads, if it is pin inserted pads, just disconnect them and inserted a new pin pads. Once you put a new set of pads on, the device will work like new again.

6. The electrode pads are not sticking, what should I do?

Make sure that the protective plastic covering the massage pads have been removed before you apply the pads to skin at the treatment area. The electrode pads are water activated. Before each use, use finger tips to get some tap water and moisture the water onto each pad on adhesive side, then shake the pads for 3-5 times, the pads will become half dry and half wet, it will be sticky again, apply the pads to the skin at the targeted area. Make sure that the pads are firmly attached to the skin for better conductivity and adhesiveness. 

Remove the old pads and replace with new pads about once a month to ensure maximum effectiveness. Also, remember to place the pads back pads holder or plastic bag right after each use to keep clean and moisture for next use. 

Attention: We are not responsible for pads from non HealthmateForever supplier which are not tested to be compatible with HealthmateForever devices. 

7. Why do I feel stinging sensations from the electrode pads sometimes?

The pads must be moist and sticky to work. Pads that are not moist enough will produce a weak and stinging sensation. Before each use dip your finger into some drops of tap water and rub the water onto the massage pads. Apply the pads to your skin when they are half wet and half dry. 

Make sure that the pads are firmly attached to the skin for better conductivity and adhesiveness. 

Worn out pads may also cause a stinging sensation. Replace the pads as needed. Even when you feel stinging sensations, you may just need to make sure that the pads are moist with water on the adhesive side of the pads.

8. I can barely feel anything from the electrode pads, what is wrong?

Check the wire connection to the pads and make sure the plug is securely plugged. Make sure the batteries are in excellent condition. Check the pads are moist and not worn out. Turn the switch off then turn on again. Please make sure both pads attach to same person’s body at the same treatment targeted area in order to feel the same sensation. Generally, increasing the intensity level gradually till you feel sensation strong enough, but comfortable.

9. I have a pacemaker, is this instrument safe for me to use?

No, unfortunately, the unit is not recommended to be used by those with a pacemaker. If you have a heart condition but are not wearing a heart pacemaker, then it is safe for you to use it.

10. Where can I apply the pads?

Apply pads to anywhere except heart, brain area or hernia. We recommend some common massage points in the manual for most effective relaxation on your body. The best way to relieve your pain is to find the pain points with fingers and apply the pads there. 

Apply the pads on or around the painful area always making sure a pair of same size pads are on nerves or muscles. The best way to relieve your pain is to find the pain points where you apply the pads.

13. What is the difference between TENS and EMS or PMS or Neuromuscular Electrical Stimulation (NMES) / Neuroprosthetics Neuromuscular Electrical Stimulation or NMES?

TENS Unit vs EMS/PMS Unit vs Neuromuscular Electrical Stimulation (NMES) / Neuroprosthetics Neuromuscular Electrical Stimulation or NMESTranscutaneous Electrical Nerve Stimulations (TENS) are safe non-invasive, drug-free methods of pain management. TENS is currently one of the most commonly used forms of electroanalgesia. The TENS device relieves pain by sending small electrical impulses through electrodes placed on the skin to underlying nerve fibers. TENS works by two different mechanisms. 

First, electrical stimulation of the nerve fibers can block a pain signal from being carried to the brain. If the signal is blocked, pain is not perceived. 

Secondly, the body has its own mechanism for suppressing pain. It does this by releasing natural compounds called endorphins which act as analgesics. 

By effectively managing pain without drugs, TENS allows many people with chronic pain conditions, to resume daily activity. TENS has proven to be beneficial in the treatment of acute and chronic pain caused by pain-related medical conditions. When TENS is used as an analgesic, patients are instructed to try different frequencies and intensities to find those that provide them with the best pain control. Optimal settings of stimulus parameters are subjective and are determined by trial and error.

Who Can Benefit? Those who need natural drug free pain relief. 

Electrical Muscle Stimulator (EMS), now called Powered Muscle Stimulator (PMS) is intended to stimulate healthy muscles in order to improve or facilitate muscle performance. 

-Relaxation of muscle spasms-Prevention or retardation of disuse atrophy 

-Increasing local blood circulation 

-Muscle conditioning 

-Immediate post-surgical stimulation of calf muscles to prevent venousthrombosis 

-Maintaining or expanding the range of motion 

Who Can Benefit? Those who need muscle reconditioning or relaxation via electrical muscle stimulation. 

Combined TENS and EMS, also known as Neuromuscular Electrical Stimulation (NMES) / NeuroprostheticsNeuromuscular Electrical Stimulation or NMES uses a device that sends electrical impulses to nerves. This input causes muscles to contract. The electrical stimulation can increase strength and range of motion, and offset the effects of disuse. It is often used to “re-train” or “re-educate” a muscle to function and to build strength after a surgery or period of disuse. 

Neuroprosthetics/Functional Electrical Stimulation refers to the use of electrical stimulation during a task. This can include walking or using an arm to reach. For example, “foot drop” is a common problem for a child with a neurological injury. The child has difficulty picking up his or her toes when walking. This may result in decreased walking speed, decreased step length, and tripping. FES can be applied to the muscles that lift the foot at the correct time during the walking cycle, which can help the child to lift and clear the foot when walking. This may result in increased strength of those muscles and increased range of motion at the ankle joint. FES can also improve safety, ease, and efficiency with walking. 

Who Can Benefit? General NMES: Children who need to gain strength or range in a certain muscle group may benefit from this service (e.g. post-surgery or general muscle weakness).Neuropresthetics: Children who may benefit from the use of these devices include those with foot drop while walking or difficulty grasping. This may include conditions such as stroke, cerebral palsy, brain injury, traumatic brain injury, or incomplete spinal cord injury.

14. Can I adjust the intensity?

Yes, you can increase the intensity of two channels or one of the channels from low to high or decrease intensity from high to low by pressing the intensity button "+" or intensity button "-" gradually per your needs till you feel comfortable.

15. How do HealthmateForever®/iSelfCare® Medical Device reduce pain? 

It sends out multiple electrical waveforms through the electrodes to relieve pain which just as traditional TENS units do. A gentle electrical current is passed through electrodes which are attached to the skin near the site of the pain or discomfort. The pulses send electrical pulses through the central nervous system, thus blocking pain. But Traditional Chinese Medicine (TCM) theory believes where there is pain, there is acupuncture point which helps unblock the blockage of passage (meridians in the body) and helps micro circulation of blood, oxygen, nutrition and energy etc.

16. Do all HealthmateForever®/iSelfCare® Medical Device have wireless feature?

No. First, you have to check the sticker on the back of each device to see if it has wireless icon. Second, the device must have a USB portal to connect with the transmitter.

17. What’s included in a single wireless Wi-9 kit?

The kit includes 1 wireless receiver, 2 sets of self-adhesive electrode pads, 1 transmitter, and 1 instruction manual. No control unit is included in the kit.

18. How far can the wireless HealthmateForever®/iSelfCare® Medical Device reach?

The wireless TENS can transmit up to 30 feet.

19. Do I need to have Wi-Fi for using wireless unit?

The wireless unit does not require WiFi for it to work as we have wireless technology to connect from control unit to wireless pads receiver.

20. Do HealthmateForever products require a Doctor’s prescription (RX)?

25. What is Acupuncture?

Acupuncture, one of the most well-known treatments based in Traditional Chinese Medicine (TCM), has evolved and innovated for thousands of years. It includes a series of procedures to stimulate various acupoints on the human body for a series of diverse medical purposes. The term, “Acupuncture” most commonly refers to one acupuncture technique, which is also most often practiced and scientifically studied, which requires penetrating under the skin with thin, solid, metal needles. The purpose of the needling procedure is to stimulate the specific acupoint in order to reach the associating health improvement or positive outcome. (Traditional Chinese Medicine: In Depth)



There are numerous acupoints located on the body. According to Schoenbart & Shefi (2014), The acupoint system has been developed based on the theory of meridians, which concluded that there are twelve regular meridians correspond to each of the six yin and six yang organs and also eight extra medians. For improvements in the health conditions of a particular organ or body part, the acupoints found along the corresponding meridian are often treated with acupuncture procedure. (Schoenbart & Shefi. 2014. Traditional Chinese Medicine Acupuncture)

How Effective Can Acupuncture Relieve Pain:

Among the various purposes, acupuncture has been reported to deliver adequate pain relief. Pain management is often what patients are looking for with acupuncture. Throughout the years, there has been scientific progress in delineating the neurobiology of acupuncture. The most telling evidence that acupuncture is effective for pain control is its use as an analgesic for surgical procedures. The needling procedure stimulates the nerve fibers near the area in pain and block or partially block pain signal being received by the brain. “Stimulation for 30 minutes before surgery enabled a reduction of chemical anesthetic by up to 50%. A 70% rate of success for pain modulation or elimination has been reported clinically in patients with low back strain, arthritis, myofascial discomfort, migraine, and other painful disorders.” (Ulett et al. 1998. Traditional and Evidence-Based Acupuncture: History, Mechanism, and Present Status) While the effectiveness of Acupuncture to work as a cure for many pain-related diseases and disorders remains equivocal, enough cases and study results have shown that Acupuncture is a practical solution to pain management.

From Acupuncture to TENS:

TENS has a reasonably short history comparing to the traditional Acupuncture invented thousands of years ago. It stands for Transcutaneous Electrical Nerve Stimulations, meaning it relieves pain by sending electrical impulses to nerve fibers. It is an alternative solution for pain management that is safe, drug-free and non-invasive. TENS is now one of the most common methods for acute and chronic pain management. Electrical stimulation of nerve fibers can stop pain signals from being transmitted to the central nervous system. Also, the contraction and relaxation of muscle caused by pulse current also release endorphins which functions as a natural analgesic. TENS shares the same featured mechanism for relieving pain by stimulating nerve fibers to block pain signals. Applying the innovative pulse current technology, TENS devices are capable of simulating the treatment of Acupuncture. Many TENS devices have the mode of Acupuncture or deep tissue massage mode. The acupuncture mode feels like being rapidly and repetitively penetrated by a thin needle when applying a TENS unit with the Acupuncture or deep tissue massage mod. No pain sensation involves in the process, but the similar heavy, achy pressure is feeling as receiving an Acupuncture treatment. TENS may not deliver precisely the same results as Acupuncture does, but since the entire process of Acupuncture process does not require applying any needles, the treatment can be conducted without restrictions of time, location, and expertise.

How Effective are TENS of Pain Relief:

Many studies have been conducted to examine the effectiveness of TENS on pain relief. In the discussion of Sluka & Walsh (2003) regarding the basic science and clinical efficacy of TENS, one evidence they took to support their argument is that, “TENS is a noninvasive modality that is easy to apply with relatively few contraindications and is used clinically by a variety of healthcare professionals for the reduction of pain.”In the study of Johnson & Ashton & Thompson in 1991, they examined the relationships between patient, stimulator and outcome variables in a large number of chronic pain patients utilizing TENS on a long-term basis, which potentially revealed the effectiveness and efficiency of TENS. 179 patients completed a TENS questionnaire designed to record age, sex, cause, and site of pain and TENS treatment regime. Of these 179 patients, 107 attended our research unit for assessment of the electrical characteristics of TENS during self-administered treatment. Although a remarkable lack of correlation between patient, stimulator and outcome variables was found to exist, the analysis revealed much information of importance: “47% of patients found TENS reduced their pain by more than half; TENS pain relief was rapid both in onset (less than 0.5 h in 75% patients) and in offset (less than 0.5 h in 51% patients); one-third of patients utilized TENS for over 61 h/week; pulse frequencies between 1 and 70 Hz were utilized by 75% of patients.” (Johnson & Ashton & Thompson. 1991. An in-depth study of long-term users of transcutaneous electrical nerve stimulation (TENS). Implications for clinical use of TENS) The results clearly show that TENS is effective and efficient to relieve pain.

To Compare Acupuncture and TENS regarding Pain Relief:

Evidence and real-life cases have proved the effectiveness of both methods of relieving pain. While the traditional procedure of Acupuncture has a history of thousands of years, it is fair to say that TENS is a more convenient and innovative solution to pain relief since it does not require needles penetrating or a well-trained practitioner and it is portable to be applied whenever and wherever. However, beyond the fact that TENS is more convenient and less time consuming, is it necessarily more efficient on pain relief comparing to the traditional Acupuncture? It becomes a question that is worth further discussing.

Acupuncture vs. TENS

Acupuncture vs. TENS

Fox & Melzack (2003) completed a study to compare the effectiveness of lower-back pain of TENS and Acupuncture. Twelve patients suffering chronic lower-back pain were treated with both Acupuncture and Transcutaneous Electrical Nerve Stimulation. The order of treatments was balanced, and changes in the intensity and quality of pain were measured with the McGill Pain Questionnaire. The results, based on the same measure of overall pain intensity, show that pain relief greater than 33% was produced in 75% of the patients by Acupuncture and in 66% by TENS. The average duration to reach pain relief was 40h after acupuncture and 23h after TENS therapy, meaning more patients found TENS brought a quicker relief to pain than Acupuncture. Although the results showed there were more patients reported pain relief after Acupuncture and TENS, statistical analyses of the data failed to reveal significant differences between the two treatments on any of the measures. Both methods, therefore, appear to be equally effective and probably have the same underlying mechanism of action. (Fox & Melzack. 2003. Transcutaneous electrical stimulation and acupuncture: Comparison of treatment for low-back pain) Thus, considering the advantages and disadvantages of both methods, it suggests that TENS is more practical for the group with pain related problems, since it, as discussed, is portable and convenient to use anywhere and anytime.


Acupuncture, as a widely used, Traditional Chinese Medical Philosophy based treatment that has been practiced for thousands of years, has made a tremendous contribution to pain relief and many other fields of medical applications. TENS, with modern technology, inherits the great heritage of Acupuncture and leads to an innovative path to pain relief. The advantages of portability and quick-effectiveness have made TENS more recommended for people with chronic pain, lower back pain, joint pain, arthritis, fibromyalgia and many kinds of pain in various part of the body. A growing number of people in pain are willing to choosing TENS as their efficient, drug-free and noninvasive solution to pain-related problems.

5.0 out of 5 stars: "Tens/IF Healthmaster", October 21, 2011

By Granna54 (Minnesota) - See all my reviews
I am more than pleased with this lil machine I have degenerative arthritis in my back and knee. This machine has saved me many steroid shots in back and knee. I love it and would not trade it for any amount of money. I also separately purchased snap to prong converters since this only comes with snaps. I wanted to be able to purchase the long back strips instead of the smaller pads. I put one long strip on back with the converter pins that go from snap to prong so I can do it myself without help. This machine is totally awesome I asked my dr what he thought of this machine before purchase, he said he had no opinion. I think I now know why it works so great you do not have to pay to see him for shots, not to mention i've been able to cut down on pain pills.

I live in minnesota where the cold is severe which flares up the arthritis even more and this machine is a lifesaver thank you so much to amazon for carrying it and healthmate forever for making it. It is also FDA approved. You will not find this machine for a lower price I've checked before my purchase there are a lot of tens machines out there but don't be fooled, if your having severe pain like I was, you need the "TENS/IF" the IF is very important.

5 out of 5: "This is a fantastic seller, ships so fast (twice a day). Extremely knowledgable, customer service orientated, and SO NICE! And her products are amazing.

5.0 out of 5 stars Essential Equipment, October 2, 2011
By Obscure Jude (Connecticut) - See all my reviews    Amazon Verified Purchase(What's this?)
I first purchased this machine after having surgery for a torn meniscus. It was extremely useful in helping with the pain that radiated down my leg. I used it therapeutically (3-4 times a day) when the pain in my leg was at its worst and subsequently for any acute injury or pain that I've had since. I used it on my shoulder with great relief after a day of gardening. It has been extremely helpful to my parents as well. When the car door swung back and hit my mother's arm she had no relief from ice, heat, and wrapping, but one treatment at a low level took all the pain away! My dad has used it for aches and pains. My sister and her daughter used it for sciatica and headaches.
It's one piece of equipment that has a miraculous and immediate impact on your health and I would strongly recommend having one in the "medicine chest."

Read the instructions where you have to apply the pads according to your affected area or disease and you are good to go. Don't waste your money on the cheap ones. I did and I regret I did not buy this one first. The modes are awesome and I assure you won't regret your purchase. Thanks for helping me with my condition.

When I first received this I was surprised that such a small unit (about 3" x 4") could be so powerful. Although it has a small learning curve it is basically easy to use. It has several settings including an acupuncture mode which feels just like real acupuncture (which I had done professionally a few years ago). Each mode has 10 levels. This machine is so powerful that most people won't go past level 6 which feels as strong as a professional tens machine (which is usually tens times bigger). It comes with a charger and only needs charging after about 10-20 uses depending on how long you use it. The only thing I don't agree with is using it every day because I learned in therapy that you have to give your joints at least one rest day between treatments to heal and recover. Also I find that 10 minutes on mode 2 (acupuncture) followed by 10 minutes on mode 1 (kneading) is perfect to get rid of most joint pain (for me in my knees and calf). I also have another larger tens unit but since I got the HealthmateForever this is the only one I use. Also the portability is great. If you want you can even take it with you and use it in your car. One of the best purchases I ever made at Amazon in my opinion.

"Contacted the seller to suggest they carry item to go along with the tem/If unit. They were very interested & going to call me back when they get the item if and when they find it. I must say I am very very impressed with this item. I was getting injections in my knee and back for degenerative arthritis that i've had for years. NO MORE SHOTS due to this gem

THANKYOU Amazon & Healthmate Forever !!"

Ive been using the massager for two weeks now and i've seen great results! I do sports so i get a lot of pain on my shoulders and the back of my neck. I use it about 2 - 3 times a week and i am very satisfied with it. Its also saving me a lot of money on physio. The pads are working fine for me haven't deteriorated quickly, though i follow the instructions and wet them each time. It has a great instruction booklet with references to pain and which massage mode you can use! The unit is easy to use looks like an ipod. Its very light and its made out of plastic material which makes it look kind of cheaply made, i hope it lasts for long.

Seller: Not all plastic materials are cheap. You will see time proves Quality material as drop test is passed by QC in our factory. We could have used metal material which will cost more like iPhone metal cover, but if it is dropped to the floor, the LCD is smashed into pieces.

Back in 2005, I suffered a severe case of whiplash. I still have symptoms from that accident. Nothing I tried at home could get into specific parts of my back, shoulders and neck. I love this little thing and truly cannot live without it!

4.0 out of 5 stars  Tcm massage, April 17, 2011
By Sam - See all my reviews     Amazon Verified Purchase(What's this?)

This unit works very well. I bought it mainly for a knot that I have in my right shoulder. I've tried massage therapy & it usually helps me for a day or two. I've found that the effects of the tcm don't wear off for about a week before I need to use it again. I'm very pleased. Ive recently introduced the unit to my dad as he has shoulder trouble as well. It does get used frequently, but the pads seem to loose their continuity in the first couple weeks. That would be my only complaint although, I do realize pads don't last forever, I just wish they went a little longer.
Seller: Thanks for feedback. It is true that the massage pads don't last very long as it is designed as replacement accessories for hygiene.
Tip: How to take care of pads?
Clean pads with water or hand sanitizer gel each time sooner after you use it and put it away in the storage box or seal in the ziplock plastic bag. If you don't use it every day, make sure to put a bit water or a drop of hand sanitizer gel, wait for a second before use. It will be more adhesive.Make sure the skin has no lotion, no oil, no powder. Better clean the massage area too before putting pads. It is suggested to replace the pads when it is not clean or sticky and no steady sensation.
Never attempt to wash the pads in the water, otherwise, the electrode of the pads will be damaged.

Hope all is well with you. I am continuing to benefit from that small  wonderful Healthmate device!! My back is a little tender at times, all in all about 95 percent better/I am also using it 
for muscle development.  Will in the future send to you some pictures.

We did not have any problem sleeping after we began to be on the scheduled massage use. My girlfriend and I were both in a car accident which caused some strain on our bodies and due to cheer leading we are always sore. After we started using the massager, we recovered faster and were not  sore. We would definitely recommend it.

I went to my dentist, got an upper wisdom tooth pulled out, went home, felt fine for 2 days. On the second night my face swelled up-Jaw all the way up to my right eye. I was in a lot of pain-took pain pills, went back to dentist 3 times. They encouraged me to continue antibiotics + pain pills and did one more X ray. They said that the site of the tooth was fine and could find no reason for the swelling + pain. I went through 3 weeks of pain +swelling, finished all medicine and had the thought maybe HealthmateForever machine could help me. For four evenings. By using HealthmateForever, swelling went down and pain was gone by the 4th time. I can also help my friends and family.

I hope you have a great new year. I sure couldn't have made it through those weeks without your help.   You know that.  Sending love to you and your family.

I'd like to tell everyone that the micro massager has helped me tremendously! I had a pain in my right foot for months and had tried everything including insoles and nothing worked at all. Then I tried the massager and in first five days time the pain was completely gone. I still continued the treatment per instructions on the massage and have been pain free until now.
Since then, I have had some minor pains such as buttocks and just following the illustrated instruction as to the appropriate acupuncture point/acupressure points. I have been able to live pain free for quite some time now and for the foreseeable future. I've recommended the massager to several friends now and will continue to do so. It is a very amazing therapeutic device.

My husband and I do enjoy HealthmateForever as pain in the shoulders is gone. I told and showed your massager to our classmates. I’m glad one of my friends bought one.

I used the massager to treat my right upper arm at level of 7. After a week, my pain was gone, but I don’t know why muscle grows like a big egg, I was little worried and had to see my 
doctor. After a thorough check including blood test, the doctor told me there was nothing wrong, the big part is just firm muscle. At this, I laugh and told everyone about this story. I really never expect to have muscle toned at age of 74.
Mary -Overland Park, Kansas
My frozen shoulder has suffered pain for about 2 years. I didn't have any better solution until I found this unit in the mall and tried about an hour. I felt reducing my pain.
I bought the massager and treated about a week. My shoulder feel no pain, now I begin to treat my back pain.
Carl Lovinelli   -Olathe KS
My wife had serious low back pain and sacro-iliac pain on the right side for awhile, but after treating the low back for a couple of days, her pain never comes back, even if she didn't treat sacro-iliac. It is unbelievable to see the very effect of TCM holistic approach. It treats individual problem by treating the whole body at the same time.  As I stand all day long, I got pain in the feet one day. I use the unit for one night, I don't feel pain any more. However, whenever there is some pain, I just use it and it relieve pain very quickly. It is so handy and convenient. We benefit a lot. It is a real option to get natural treatment without any medication. Thanks a lot.

"Shipped quickly & efficiently. Rec'd in excellent condition. would do business with seller again"  
Date: November 3, 2010    Rated by Buyer: Robert
I tried this while shopping around in the mall. It's a little expensive, but you spend the same amount of money with a couple visits to the chiropractor or acupuncture therapist, so I figured it was worth it as the ad says  "Be your own therapist, one time investment, health mate forever". It is said Chinese medical massage is one branch of the Chinese medical care.
It has unique and marvelous effect. After sports, I use it to relieve fatigue. Whenever I have some pain from now and then, I just use it to heal my pain right way.

HealthmateForever is so cool after I tried it at my low back at kiosk. I was sold. I’m also very happy with the unit and price.
Brenda Black  - Kansas City Missouri   
I tried at kiosk on the shoulders at the same time with another customer. I bought it too as the sensations are great and feel so much relaxed after about 20 minutes try. I'm thinking 
about becoming a dealer. Do you provide professional training?

My associates and I tried HealthmateForever. It works great. It is really good for relieving pain and sports injury recovery.
Curtis from Garry Gribble's Running Sports, Kansas City MO
I tried the therapy device in the mall on my tight shoulders several times. Now I feel much relaxed. It is so cool in design just like iPod, great sensations and very effective.  I 
immediately ordered 2 HealthmateForever for helping my students recover from the sports injury.
