HealthmateForever Medical Devices

HealthmateForever medical devices combine TENS, EMS/PMS, bio-electricity technology, human-body simulation technology, and advanced digital programming in a compact, pocket-sized design that is convenient, portable, and easy to use.

Our combined TENS/EMS/PMS systems use bio-electric stimulation technology to interact with the human body and deliver controlled electrical impulses through the body. Human-body simulation technology is incorporated to simulate various traditional therapeutic techniques and methods inspired by ancient Chinese practices.

Our devices also incorporate TENS and muscle stimulation technology to produce controlled motor and muscle contractions for muscle reconditioning, strengthening, and relaxation.

Advanced modern programming technology allows these functions to be integrated into a compact, pocket-sized device, making HealthmateForever convenient and portable for everyday use.

Drug-Free, Non-Invasive Pain Management Technology

The HealthmateForever TENS/EMS/PMS system is a drug-free, non-invasive approach to pain management and muscle stimulation.

The system includes both manual and automatic modes.

Manual modes simulate different massage techniques and stimulation methods, allowing users to select and adjust specific stimulation patterns.

Automatic modes use pre-programmed electrical pulses and stimulation sequences designed to provide different types of stimulation experiences, ranging from gentle soft-tissue stimulation and deeper stimulation to invigorating muscle stimulation and soothing relaxation.

This combination of technologies gives users greater flexibility to personalize their stimulation experience according to their individual needs and preferences.

Inspired by Traditional Chinese Medicine

Traditional Chinese Medicine (TCM) has used acupuncture points and meridian-based therapeutic concepts for thousands of years.

According to traditional TCM theory, pain may be associated with blockages or imbalances along the body's meridians. Traditional practices use acupuncture points and other therapeutic techniques to address these concepts and support the body's balance and circulation.

HealthmateForever's human-body simulation technology draws inspiration from these traditional therapeutic concepts and combines them with modern electrical stimulation and digital programming technology.

Traditional wisdom meets modern technology.

TENS, EMS and NMES Technology

On today's market, combined TENS and EMS technology is also commonly associated with NMES, or Neuromuscular Electrical Stimulation.

Neuromuscular Electrical Stimulation (NMES) uses a device to deliver electrical impulses to nerves, causing muscles to contract.

Electrical stimulation can be used to support muscle strength and range of motion and to help address the effects of muscle disuse. It is also commonly used to help re-train or re-educate muscles and support muscle function and strength following surgery or periods of inactivity.

HealthmateForever incorporates these established electrical stimulation technologies into compact, digitally controlled devices designed to provide users with greater flexibility and control.

A History of Innovation

HealthmateForever has been committed to innovation in the development of compact digital TENS/EMS technology.

In August 2012, HealthmateForever introduced an innovative patented design for a compact digital TENS/EMS unit with a size comparable to an iPod, along with a digital display featuring a backlight.

HealthmateForever was also the first to design isolated, independent intensity control for both A and B channels in its digital TENS/EMS units, giving users independent control over stimulation intensity on each channel.

In 2014, HealthmateForever introduced touchscreen TENS/EMS units, bringing touchscreen technology to the portable electrical stimulation category.

These innovations reflect HealthmateForever's ongoing commitment to making advanced electrical stimulation technology more compact, portable, convenient, and user-friendly.

Pulse Rate: <100HZ 

Max output amplitude: <5V (r.m.s)

HealthmateForever TENS and EMS devices feature a variety of electrical pulse frequencies and waveform patterns, with up to 40 different stimulation modes, depending on the model. This makes HealthmateForever different from many traditional analog TENS and EMS devices on the market, which typically provide only one constant stimulation pattern or a limited number of different sensations.

With repeated use, the body may become accustomed to the same stimulation sensation. When the same sensation is repeated continuously, it may become less noticeable over time.

HealthmateForever takes a different approach. Our TENS and EMS technology provides a variety of electrical stimulation patterns and massage-like sensations, creating a more dynamic and varied experience rather than relying on a single constant sensation.

With multiple modes and stimulation patterns to choose from, HealthmateForever gives users a more versatile and personalized experience every time they use their device.

HealthmateForever® TENS and Power Muscle Stimulator devices combine traditional TENS/EMS technology with bioelectric stimulation, modern digital programming, and stimulation concepts inspired by traditional Chinese therapeutic techniques.

Our digital TENS and EMS devices offer a variety of electrical pulse waveforms and stimulation programs, with up to 40 modes on selected models. This provides a wider range of stimulation patterns and sensations than conventional analog TENS and EMS devices that may offer only one or a limited number of stimulation patterns.

How to Use and Care for Your Electrode Pads

Before applying the electrode pads, clean and dry your skin to ensure proper contact. Always apply the pads in pairs as directed.

If the pads become dry, apply a few drops of clean tap water to lightly moisten the adhesive surface.

If the pads become excessively sticky due to high humidity, you may place the sealed pads in a cool refrigerator to help extend their usable life.

Never leave the electrode pads unattended or expose them to direct sunlight. Keep them sealed and properly stored when not in use.

How Long Do Electrode Pads Last?

The lifespan of electrode pads depends on how frequently and how long they are used. Under normal conditions, a set of pads may last from approximately one month to several months.

If the pads begin to lose their adhesiveness, lightly moistening the adhesive surface may help restore their stickiness.

When the pads become worn, damaged, or no longer maintain proper adhesion, it is time to replace them.

Replacement electrode pads can be ordered from the Accessories section of our online shop.

How to Replace Your Electrode Pads

Replacing the pads is simple.

For snap-button electrode pads, simply unsnap the buttons on the back of the used pads and snap the new pads into place.

For pin-type electrode pads, disconnect the existing pads and insert the new pin-type pads.

Once a fresh set of electrode pads is installed, your HealthmateForever device is ready to use again.

Fresh pads. Proper contact. Better performance.

Please read the following safety information carefully before using a HealthmateForever®/iSelfCare® TENS/EMS/PMS device.

• The long-term effects of chronic electrical stimulation are unknown.
• Do not apply the TENS/EMS unit to the carotid sinus nerves, particularly in individuals with a known sensitivity to the carotid sinus reflex.
• Do not apply the TENS/EMS unit over the neck or mouth. Severe spasms of the laryngeal muscles may occur, and the resulting contractions could be strong enough to close the airway or cause difficulty breathing.
• Do not apply the TENS/EMS unit across the chest or near the heart. Introducing electrical current into the heart may cause cardiac arrhythmias.
• Do not apply the TENS/EMS unit transcerebrally (across the head).
• Do not apply the TENS/EMS unit over swollen, infected, or inflamed areas, skin eruptions, or areas affected by conditions such as phlebitis, thrombophlebitis, or varicose veins.
• Do not apply the TENS/EMS unit over or near cancerous lesions.
• Do not use the TENS/EMS unit during pregnancy unless specifically instructed to do so by a healthcare professional.
• Do not use the TENS/EMS unit if you have a pacemaker or other implanted electronic medical device, unless specifically cleared by your physician.
• Do not use the TENS/EMS unit if you have a heart condition unless your healthcare professional has determined that it is appropriate for you.
• Do not use the TENS/EMS unit if you have epilepsy or another medical or neurological condition unless your healthcare professional has advised that it is appropriate for you.

When in doubt, consult your doctor or other qualified healthcare professional before using the device.

The electrode pads need to be slightly moist and sticky to provide good contact with the skin. Pads that are too dry may result in weak stimulation or a stinging sensation.

Before each use, dip your finger into a few drops of clean tap water and gently rub the water onto the adhesive side of the electrode pads. The pads should be moist but not overly wet when you apply them to your skin.

Make sure the electrode pads are firmly and evenly attached to the skin to ensure good conductivity and proper adhesion.

Worn or damaged electrode pads may also cause a stinging sensation. Replace the pads when they become worn out or no longer maintain proper adhesion.

If you experience a stinging sensation during use, first check the electrode pads and make sure the adhesive side is properly moistened with water and firmly attached to the skin. You may also reduce the intensity to a comfortable level.

If the stinging sensation continues or becomes painful, stop using the device and remove the electrode pads.

If you can barely feel the stimulation from the electrode pads, check the following:

• Check the wire connection. Make sure the wires are properly connected to the electrode pads and that the plugs are securely inserted into the device.
• Check the batteries. Make sure the batteries are in good condition and have sufficient power.
• Check the electrode pads. Make sure the pads are properly moistened and have not become worn out or damaged.
• Restart the device. Turn the device off, wait a few seconds, and then turn it back on.
• Check pad placement. Make sure both electrode pads are attached to the same person's body and positioned on the intended treatment area as directed.
• Adjust the intensity. Gradually increase the intensity level until you feel a stimulation that is strong enough to be noticeable but still comfortable.

Proper pad contact, sufficient moisture, secure connections, adequate battery power, and an appropriate intensity level are all important for a consistent stimulation experience.

Tip: If you still feel little or no stimulation after checking these items, make sure the electrode pads and wires are functioning properly and replace worn pads if necessary.

No. Do not use HealthmateForever TENS/EMS/PMS devices if you have a pacemaker or other implanted electronic cardiac device unless your physician or qualified healthcare professional has specifically determined that use is appropriate for you.

Electrical stimulation from TENS and EMS devices may interfere with the operation of an implanted cardiac device, including a pacemaker or implantable cardioverter-defibrillator (ICD). Possible interference may affect how the cardiac device senses or delivers therapy.

If you have a pacemaker, ICD, or another implanted electronic medical device, consult your cardiologist or the physician managing your implanted device before using any HealthmateForever electrical stimulation device.

Do not use the device unless you have received specific medical guidance confirming that it is appropriate for you.

Electrode pads should be applied to the appropriate areas of the body according to your device's instructions. Do not apply the pads over the heart, across the head/brain area, or directly over a hernia. Always follow the safety precautions and electrode-placement instructions provided with your specific model.

For pain relief, apply the pads on or around the painful or uncomfortable area. You can use your fingers to locate the area of discomfort and position the pads accordingly. When using a pair of pads, make sure the pads are the same size and are positioned appropriately over the targeted muscles or along the nerves in the treatment area.

For relaxation and massage, HealthmateForever®/iSelfCare® manuals provide examples of commonly used massage points and body locations. Different pad placements and stimulation modes can produce different sensations, so adjust placement and intensity according to the treatment area and your comfort level.

Muscle Stimulation

HealthmateForever® TENS/EMS/PMS devices provide electrical muscle stimulation that can produce controlled muscle contractions. Depending on the specific model and its intended use, muscle stimulation may support muscle conditioning, reconditioning, relaxation, or maintenance of muscle function.

Muscle stimulation may be useful for people with sedentary lifestyles or those who spend prolonged periods sitting, when appropriate for the individual and the intended use of the device. For postpartum abdominal muscle stimulation, or for use following surgery or an extended period of inactivity, consult your doctor or another qualified healthcare professional before use and follow their instructions.

Electrical muscle stimulation should not be represented as a substitute for exercise or as a guaranteed method of reducing cellulite or reshaping the body. Results vary by individual and depend on the specific device, stimulation program, and intended use.

Relaxation and Massage

HealthmateForever®/iSelfCare® TENS/EMS/PMS devices can also provide a variety of stimulation sensations for relaxation and soothing massage. Depending on the selected mode and intensity, stimulation may feel like gentle pulsing, tapping, rhythmic massage, or deeper tissue stimulation.

The devices may also be used to provide soothing stimulation to tired, sore, or strained muscles, depending on the specific model and its intended use.

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.

Yes. HealthmateForever®/iSelfCare® devices allow you to adjust the stimulation intensity according to your personal comfort level.

Start at a low intensity and gradually increase it until you feel a strong but comfortable stimulation. The appropriate intensity may vary depending on the treatment area, stimulation mode, and individual sensitivity.

For devices with independent A and B channel controls, you can adjust the intensity of each channel separately for a more personalized stimulation experience.

Do not increase the intensity to a level that causes pain or significant discomfort.

HealthmateForever®/iSelfCare® TENS devices use controlled electrical impulses delivered through electrode pads placed on the skin. These electrical impulses stimulate the underlying nerves and may help reduce the perception of pain through several mechanisms.

First, TENS stimulation may help interfere with the transmission of pain signals to the brain. By stimulating sensory nerve fibers, TENS may reduce the ability of pain signals to be perceived, helping to decrease the sensation of pain.

Second, electrical stimulation may activate the body's natural pain-relief mechanisms. TENS may encourage the release of naturally occurring compounds such as endorphins, which can act as natural analgesics.

HealthmateForever®/iSelfCare® devices offer a drug-free, non-invasive approach to pain management without the use of medications, chemicals, or creams.

Different stimulation modes, frequencies, and intensity levels can produce different sensations. Users can select the mode and gradually adjust the intensity to find a stimulation level that is strong enough to feel but remains comfortable.

Important: TENS does not necessarily eliminate the underlying cause of pain. It is intended to provide temporary relief or management of pain symptoms. Always follow the instructions for your specific device and consult your healthcare professional when appropriate.

First, check the sticker on the back of your device to see whether it has the wireless icon.

Second, the device must have a USB port for connecting to the transmitter.

If your device has both the wireless icon and the required USB port, it is designed to support the wireless transmitter.

Please refer to our 2020 Version Comparison Chart to compare the features and specifications of each model and choose the device that best fits your needs.

Note: Not every feature is available on every model. Please check the specifications and user manual for the specific HealthmateForever®/iSelfCare® device before purchasing.

Channels A and B can be adjusted independently, allowing you to set a different stimulation intensity for each channel. This is almost like having two stimulation units built into one device, giving you greater flexibility and control when treating two different areas at the same time.

For example, you can set Channel A to one intensity level while setting Channel B to a different intensity level based on the stimulation needs and comfort of each treatment area.

Two channels. Independent intensity control. One convenient device.

For Example: model# T24AB2

1. Does using both A and B double the impact?

No. Using both channels allows you to use additional electrode pads and treat or cover additional areas at the same time. It should not be understood as simply doubling the stimulation or therapeutic effect.

2. Do A and B need to be set at the same intensity?

No. A and B are completely independent.

For example, you may set A at intensity 5 and B at intensity 10. Each should be adjusted separately according to the treatment area and a comfortable level of stimulation.

3. How should I understand the intensity and the four outlets?

This is the key point.

The four outlets are not four 25% portions of one total output.

The intensity you select for Channel A represents the full (100%) selected intensity available to Channel A, and the intensity selected for Channel B represents the full (100%) selected intensity available to Channel B.

Within each channel:

• If you use A1 alone, A1 receives 100% of the selected Channel A intensity.

• If you use A2 alone, A2 receives 100% of the selected Channel A intensity.

• If you use A1 and A2 simultaneously, the Channel A output is shared between A1 and A2, approximately 50% to each.

The same principle applies independently to Channel B:

• B1 alone = 100% of the selected B intensity

• B2 alone = 100% of the selected B intensity

• B1 + B2 together = the selected B output is shared, approximately 50% to each

Therefore, if you use only one of the four outlets, it is not limited to 25% of the device’s intensity. This is the main distinction.

A and B remain independently adjustable regardless of which outlets are being used.

For Example: model# Pro24AB2

Make sure to charge both Wi9 receiver disc and TENS machine before you use them per user manual of TENS device and Wi9 receiver disc with USB & AC wall charger for about a couple of hours.

1. Snap on the oval shaped adhesive electrode pad to the Wi9  disc,  apply the pad to your affected area, such as lower back;

2. Plug the little black USB wireless transmitter in the charging port of the TENS unit , 

3. turn on the Wi9 receiver disc first, (one or more than one if you need, ) before you turn the TENS device

4. After pairing, the Wi9 receiver disc should have light on A in blue and power light on in red; Then you see both TENS device or Wi9 receiver disc are at default channel A when both are on. 

5.(If you want to use Channel B, you can switch from A to B by press the device and disc center button.)

6.  The TENS device defaults at mode 1, 20 minute timer, then choose mode by press M+ or M- button up or down, then Press A+ to increase intensity until you feel strong enough and comfortable or Press A- to decrease intensity, then Press T to adjust timer from 20 minutes up to 80 minutes per your need; Channel A of the device is all set.

 At the same time, if you also want to use the same device to control Channel B to control the Wi9 receiver disc if you you turn on the second Wi9 Receiver disc.

Press the center button of the device to switch from channel A to channel B and you should see the B blinks on the top of the LCD screen next to time icon, then switches from channel A to channel B on the disc by pressing the center button of the other wireless receiver disc.  

If you just use the device to control both wireless receiver discs at the same channel A, you do not need to press the center button of the both discs One device can control unlimited several Wi9 wireless receiving discs around your body if you need to buy more than 2 wireless kits.  

  Note: The wireless kit includes two oval-shaped non-woven conductive electrode pads. One pad is already snapped onto the wireless receiver disc, while the second pad is provided as a spare for future replacement.  

Acupuncture is one of the best-known therapeutic practices rooted in Traditional Chinese Medicine (TCM). It has evolved and developed over thousands of years and includes a variety of techniques designed to stimulate specific points, known as acupoints, on the human body for different therapeutic purposes.

The term “acupuncture” most commonly refers to the technique that is most widely practiced and studied scientifically: the insertion of thin, solid metal needles through the skin at specific acupoints.

The purpose of needling is to stimulate selected acupoints based on traditional TCM principles, with the goal of supporting desired health benefits or therapeutic outcomes.

HealthmateForever®/iSelfCare® technology is inspired in part by traditional therapeutic concepts and stimulation techniques associated with TCM, while using modern electrical stimulation technology rather than acupuncture needles.

Acupuncture

Acupuncture is one of the best-known practices rooted in Traditional Chinese Medicine (TCM). TCM has evolved over thousands of years and includes a variety of traditional approaches, including acupuncture, that use specific points on the body for different therapeutic purposes.

The term “acupuncture” most commonly refers to the insertion of thin, solid needles through the skin at specific points, known as acupoints. Acupuncture has been studied scientifically for a variety of conditions, particularly pain. Research suggests that acupuncture may help relieve certain types of pain, including some back, neck, and osteoarthritis pain, although the strength of evidence varies depending on the condition.

Research into how acupuncture works is ongoing. Studies suggest that acupuncture may affect the nervous system and other body tissues, and may influence the body's natural pain-processing mechanisms. However, the precise mechanisms are not fully understood, and some of the observed benefits may be related to nonspecific effects such as expectations and other aspects of treatment.

HealthmateForever®/iSelfCare® and TCM-Inspired Stimulation

HealthmateForever®/iSelfCare® technology is inspired in part by traditional stimulation concepts associated with TCM and acupuncture, including the use of selected points on the body.

However, HealthmateForever®/iSelfCare® electrical stimulation is not acupuncture and does not use acupuncture needles. Our devices use electrical stimulation delivered through electrode pads placed on the skin.

The fact that acupuncture has been studied for certain health conditions does not mean that HealthmateForever®/iSelfCare® devices have been clinically proven to provide the same effects as acupuncture. Any specific medical or therapeutic claim for a HealthmateForever®/iSelfCare® device should be based on the indications and evidence applicable to that specific device.

Our TCM-related information is provided to explain the traditional concepts that inspired certain aspects of our technology and is not intended to represent that our devices reproduce, replace, or are equivalent to traditional acupuncture treatment.

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.

Acupuncture and Pain Management

Among the many traditional applications of acupuncture, pain management has been one of the most widely studied areas. Acupuncture has been investigated for various types of pain, and research suggests that it may provide pain relief for certain conditions. However, the strength of the evidence varies depending on the type of pain and the specific clinical situation.

Scientific research has also advanced our understanding of the potential neurobiological mechanisms associated with acupuncture. Studies suggest that acupuncture may influence the nervous system and the body's natural pain-processing mechanisms. However, the precise mechanisms of acupuncture are not completely understood.

Historical and scientific literature has reported the use of acupuncture for pain control in a variety of clinical settings. For example, Ulett et al. (1998), in Traditional and Evidence-Based Acupuncture: History, Mechanism, and Present Status, discussed proposed mechanisms and clinical applications of acupuncture. The findings and statistics reported in individual publications should be understood within the context of the studies from which they originated and should not be interpreted as a guarantee of results for every patient.

While acupuncture continues to be studied and its effectiveness varies by condition, a substantial body of research has examined its potential role in pain management.

TENS, or Transcutaneous Electrical Nerve Stimulation, has a much more recent history than traditional acupuncture. TENS uses controlled electrical impulses delivered through electrode pads placed on the skin to stimulate underlying nerve fibers.

TENS provides a non-invasive, drug-free approach to pain management. It has been widely used and studied for both acute and chronic pain conditions.

One proposed mechanism of TENS is that electrical stimulation of sensory nerve fibers may influence the transmission and perception of pain signals within the nervous system. TENS may also activate the body's natural pain-modulating mechanisms, including the release of endogenous opioids such as endorphins.

TENS and Acupuncture-Inspired Stimulation

Although TENS and acupuncture are different treatments, certain TENS stimulation patterns can be designed to produce sensations inspired by traditional acupuncture or massage techniques.

Some HealthmateForever®/iSelfCare® devices include Acupuncture Mode or Deep Tissue Massage Mode, depending on the model. These stimulation patterns may produce sensations that users describe as rhythmic, tapping, pulsing, or pressure-like stimulation.

The sensation may resemble aspects of the pressure or stimulation experienced during acupuncture, but TENS does not penetrate the skin with needles and is not the same treatment as acupuncture.

HealthmateForever®/iSelfCare® TENS technology therefore provides a convenient, non-invasive method of electrical stimulation through electrode pads rather than acupuncture needles. It can be used at home and does not require needle insertion.

However, TENS should not be represented as providing exactly the same clinical effects or results as acupuncture. The two approaches use different techniques and mechanisms, and evidence supporting acupuncture does not automatically establish the effectiveness of a TENS device.

HealthmateForever®/iSelfCare® devices combine modern electrical stimulation technology with stimulation patterns inspired by traditional therapeutic concepts, providing users with a drug-free and non-invasive option for personal pain-management and relaxation routines.

Using a TENS unit

How Effective Is TENS for Pain Relief?

Many clinical and scientific studies have examined the use of Transcutaneous Electrical Nerve Stimulation (TENS) for pain management.

In their review of the basic science and clinical efficacy of TENS, Sluka and Walsh (2003) described TENS as a non-invasive treatment that is relatively easy to apply and has relatively few contraindications when used appropriately. TENS has been used by a variety of healthcare professionals as one approach to pain management.

A 1991 study by Johnson, Ashton, and Thompson examined the relationship between patient characteristics, stimulation parameters, and treatment outcomes among long-term users of TENS. The study included 179 patients who completed a questionnaire regarding their age, sex, cause and location of pain, and TENS treatment regimen. Of these patients, 107 were assessed for the electrical characteristics of TENS during self-administered treatment.

The researchers reported that 47% of the patients experienced a reduction in pain of more than half. They also reported that pain relief occurred relatively quickly in many patients, with 75% experiencing onset of relief within 30 minutes and 51% reporting that relief diminished within 30 minutes after stopping stimulation. The study also found that patients used a wide range of stimulation frequencies and treatment schedules.

These findings provide useful evidence regarding how TENS was used and experienced by a group of long-term users. However, individual responses to TENS can vary, and results from one study should not be interpreted as a guarantee that TENS will provide the same degree of pain relief for every person.

Comparing Acupuncture and TENS for Pain Relief

Both acupuncture and TENS have been studied as approaches to pain management, but they are different treatments.

Acupuncture traditionally involves the insertion of fine needles into specific points on the body, while TENS delivers controlled electrical stimulation through electrode pads placed on the skin.

One potential advantage of TENS is convenience. TENS is non-invasive, does not require needles, and compatible portable devices can be used outside of a clinical setting according to the device's instructions. Acupuncture, by contrast, generally involves treatment by a trained practitioner.

However, convenience does not necessarily mean that TENS is more effective than acupuncture for pain relief. The effectiveness of each approach depends on the individual, the type and cause of pain, treatment parameters, and other factors. Direct comparisons between acupuncture and TENS should be based on studies that specifically evaluate the two treatments under comparable conditions.

HealthmateForever®/iSelfCare® TENS devices are designed to provide a convenient, drug-free, non-invasive approach to electrical stimulation and pain management. They should not be represented as a replacement for acupuncture or as clinically superior to acupuncture unless supported by appropriate device-specific evidence.

Acupuncture vs. TENS

Comparing TENS and Acupuncture for Low-Back Pain

Fox and Melzack conducted a comparative study of acupuncture and transcutaneous electrical stimulation for chronic low-back pain. Twelve patients with chronic low-back pain received both acupuncture and transcutaneous electrical stimulation. The order of the two treatments was balanced, and changes in pain intensity and pain quality were measured using the McGill Pain Questionnaire.

Based on the measure of overall pain intensity, pain relief greater than 33% was reported by 75% of patients following acupuncture and 66% following transcutaneous electrical stimulation. The mean duration of pain relief was approximately 40 hours after acupuncture and 23 hours after electrical stimulation. Although some measures favored acupuncture, statistical analysis did not identify significant differences between the two treatments. The study therefore did not demonstrate a statistically significant difference between acupuncture and transcutaneous electrical stimulation in this small group of patients.

These findings suggest that both acupuncture and TENS may provide pain relief for some people with chronic low-back pain, while offering different practical advantages. TENS is non-invasive, uses electrode pads rather than needles, and can be used at home with an appropriate device and according to its instructions. These characteristics can make TENS a convenient option for people seeking a drug-free approach to pain management.

It is important to note that this study involved only 12 patients and specifically evaluated chronic low-back pain. Its results should not be interpreted as proof that TENS and acupuncture are equally effective for every type of pain or for every individual. More recent evidence regarding TENS for chronic low-back pain is mixed, underscoring the importance of considering the condition, treatment parameters, and individual response.

Conclusion

Acupuncture is a traditional medical practice with a history spanning thousands of years and has been studied for pain management and other health conditions. TENS represents a modern, non-invasive approach to electrical stimulation that can provide an alternative way to manage certain types of pain without needles or medication.

The Fox and Melzack study provides an early example of research directly comparing acupuncture and transcutaneous electrical stimulation for chronic low-back pain. While the study did not demonstrate a statistically significant difference between the two treatments, it provides useful historical evidence regarding the potential of electrical stimulation as an alternative approach to pain management.

Today, TENS is used as a drug-free, non-invasive approach to pain management for certain types of pain. Its portability and ease of use may make it a convenient option for people who prefer an at-home approach. However, individual responses vary, and TENS should not be presented as universally more effective than acupuncture or as a replacement for professional medical care.

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.

5.0 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."

This little machine cured my cervical and arm pains. I had a stiff neck and my arm was hurting all the time. 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.

 5.0 out of 5 stars fantastic therapy!
August 12, 2011 By Nathan - See all my reviews  Amazon Verified Purchase(What's this?)

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.

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.

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.

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'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.

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.

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.

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.
