How Can I Make My Tens Pads Sticky Again
When theyre taking up the sticky surface area, theres less of the adhesion to adhere to your skin. To make TENS unit pads sticky again after theyve become dirty, you can simply clean them with a damp washcloth. Be sure to only use cloth, not a paper substitute, as this will just leave behind more debris.
How Ems And Tens Machines Work
A TENS machine, also known as a TENS unit or a nerve stimulator, consists of an electrical impulse generator connected to electrodes placed on your skin. It works by delivering small electrical impulses to stimulate the mechanisms that cause pain. TENS machines work in three different ways:
- They block the transmission of pain signals to the brain.
- They stimulate the production of endorphins .
- They improve blood circulation.
An EMS machine works in more or less the same way. It also consists of an electrical impulse generator connected to electrodes that are placed on your skin around the muscle to be treated. It also works by sending small electrical impulses, which this time are delivered directly to the muscle, causing it to contract. The muscle contracts and relaxes repeatedly, which helps to improve blood circulation, which in turn serves to:
- Relax the muscle
- Stimulate muscle growth
What Are The Advantages Or Benefits Of Transcutaneous Electrical Nerve Stimulation Therapy
TENS is a non-invasive method of pain relief. It can be used alone or in addition to prescriptions or over-the-counter pain-relieving medications. The amount of medication may be able to be reduced in some patients who use TENS therapy. Do not stop taking or make any adjustments in your dose of medications without discussing it with your doctor first.
Another benefit of the TENS unit is that it is small and portable and therefore can be used at home or away, anytime pain relief is needed.

Benefits Of Using A Tens Unit For Nerve Pain
TENS units are the ideal solution to nerve pain, as their very design focuses on nerve manipulation and pain relief. And while it might seem counterintuitive to think that nerve stimulation could help facilitate nerve-related pain relief, these processes work hand-in-hand.
While the exact mechanism behind TENS units isnt completely understood, there are two competing theories as to how these stimulating machines help reduce the sensation or perception of pain signals.
The first theory, known as the Gate Control Theory, says that TENS units produce enough electrical stimulation to override gates along the spine that process pain signals, effectively blocking them from reaching the brain. At the very least, according to this theory, TENS units can prolong the time between each received signal.
The second theory is often called the Endorphin Release Theory. This one purports that TENS units cause the body to enter a slightly stressed state, causing increased hormone production. The primary hormone released during this state is endorphin, a naturally occurring drug that increases heart rate and body-wide circulation.
No matter how these machines work their magic, they are often incredibly effective. And while some users may not experience as many apparent benefits or effects, the majority of TENS users do report at least a minimal improvement in pain management.
Common Causes Of Foot Pain
There are various sources of foot pain, and Plantar Fasciitis is among the most common. Plantar Fasciitis is just a disorder of the ligaments insertion site on the bone. The characteristics of the condition include scarring, collagen breakdown, and micro-tears.
A heel spur is just a bony protrusion where calcium deposit forms at the underside of your heel bone. Examining through an X-Ray, the protrusion can extend as much as half an inch.
Heel spurs are often painless but are also likely to cause pain. There is often an association between heel spurs and Plantar Fasciitis. Foot muscles and ligament strains, continual tearing of the membrane and stretching of Plantar Fascia are leading causes of Heel spurs.
Peripheral neuropathy is another foot pain causing the condition. If you are suffering from peripheral neuropathy, it will be as a result of peripheral nerve damage. The condition that typically affects your hands and feet causes pain, numbness, and weakness.

And Central Stimulation Tickling The Brain And Spinal Cord With Electricity
And then theres central stimulation stimulation of the spinal cord or brain the other major kind of neuromodulation. Its possible to do this non-invasively, but probably not possible to do it well . To get it right, youve probably got to get right in there with an actual implant: more invasive, profound, and dangerous, but also more impressive results for more serious problems like Parkinsons diseases, major depression, and severe chronic pain. This approach has roots in electroconvulsive therapy electroshock therapy back in the day but the modern era of electrical therapy began when deep brain stimulation was introduced in 1987, and its been steadily improving since then, mostly thanks to better surgical techniques for implants.
Now, if only we knew how it worked! No one actually does, and there are several possibilities, like vagus nerve stimulation to control inflammation for rheumatoid arthritis extremely interesting, but far from an established effect.6 Thats an advanced topic, beyond the scope of this article, but it’s a topic worth watching over the next decade.
As brain-machine interfaces continue to improve, we are likely to see some real progress. Consider a 2021 study that demonstrated substantial pain relief using a smart implant in rat brains.7 Cool stuff! But its about as close to TENS as rocket science is to paper airplanes.
Intensity Of Tens Established As A Critical Factor In Efficacy
The intensity of stimulation utilized is critical with TENS application. Using the strongest intensity that remains comfortable produces hypoalgesia in healthy subjects lower intensities are ineffective . In addition to activation of greater numbers of sensory afferents, higher pulse amplitudes are proposed to activate deeper tissue afferents allowing for greater analgesia . High intensity TENS decreases post-operative opioid requirements and negative opioid-side effects . Even as researchers demonstrate the importance of intensity in TENS delivery, TENS systematic reviews continue to include studies with wide ranging intensity settings. In fact, as outlined below, application of TENS at inadequate intensities is one of the primary factors attributed to conflicting reports of TENS efficacy. Therefore, clinicians should strive to apply TENS at the maximally tolerated intensity for each individual person.

What Are The Types Of Transcutaneous Electrical Nerve Stimulation
There are three methods by which TENS maybe applied:
- Conventional TENS high frequency/low intensity stimulation
- Acupuncture-like TENS low frequency/high intensity
- Pulsed or intense TENS the nerve stimulation comes in short bursts
Conventional TENS is the most commonly used method. The pain relief is almost immediate, but for a short duration. Some patients may not tolerate the higher intensities. These levels are only for those who do not respond to conventional TENS.

The Evidence For Tens For Pain Control
A 2020 review suggests that the use of TENS has positive outcomes in treatment of Primary Dysmenorrhea.
A 2014 study set out to provide a critical review of the latest basic science and clinical evidence for TENS. Key findings were:
- Application of TENS at inadequate intensities is one of the primary factors attributed to conflicting reports of TENS efficacy. Using the strongest intensity that remains comfortable produces hypoalgesia in healthy subjects is imperative lower intensities are ineffective. In addition to activation of greater numbers of sensory afferents, higher pulse amplitudes are proposed to activate deeper tissue afferents allowing for greater analgesia. High intensity TENS decreases post-operative opioid requirements and negative opioid-side effects.
- Both High Frequency and Low Frequency TENS been shown to provide analgesia specifically when applied at a strong, non-painful intensity. HF TENS may be more effective for people taking opioids.
- Effective analgesia for chronic pain conditions may be limited by the development of tolerance to TENS if repeated application of either HF or LF TENS at the same frequency, intensity and pulse duration is used daily.
- Application of TENS electrodes at acupoint sites may increases analgesia and targeting the use of TENS during movement or required activity may provide the most benefit.
Some Guidelines When Using Tens
- Before applying the electrodes, it is important to remove all lotions, oils, or other applications to the skin. You may want to shave hair from the local area where the electrode will be applied.
- Daily use of TENS for several hours at a time is recommended. You should not wear the unit for long periods of time or during extended sleep time .
- Never place an electrode over an open wound or area of skin irritation. Report any skin problems or burns immediately.
- Do not place electrodes near your eyes or over your throat.
- Do not use TENS in the shower or bathtub.
- Move the electrodes a bit each time you put them on to avoid skin irritation.
- You should experience a comfortable tingling sensation that is comfortable enough to allow you to complete daily tasks and activities.
- You may want to keep a daily journal of your pain levels, the settings you use, and a record of the medications you are taking for pain relief. By reviewing your notes, you may find the best combination of electrode placement and unit settings that gives you the most pain relief.

How Does Transcutaneous Electrical Nerve Stimulation Work
There are two theories about how transcutaneous electrical nerve stimulation works. One theory is that the electric current stimulates nerve cells that block the transmission of pain signals, modifying your perception of pain. The other theory is that nerve stimulation raises the level of endorphins, which are the bodys natural pain-killing chemical. The endorphins then block the perception of pain.
Could Tens Cause Pain Or Other Neurological Symptoms
Other than direct injury, its conceivable that TENS could backfire and actually cause pain instead of relieving it. Ive wondered about this, and went looking for evidence of it and found none. If it occurs, its rare and relatively minor.
But I still think its plausible. Any unusual stimulus can potentially be a trigger for the symptoms of certain diseases . A TENS backfire would not involve any harm to the nerves themselves, just a sensory over-reaction.12 Many cases of backfiring might not quite reach the level of pain. For instance, mild numbness, tingling, and other paresthesias are also possible. These are extremely common symptoms in people even when we arent pumping electric current through our flesh, and they usually are completely harmless and temporary, triggered by a variety of minor physiological and psychological circumstances. The strange sensations of TENS, for some patients, might trigger an attack of tingling or numbness.
The best defense against such reactions to TENS or any weird stimulus is mental confidence and optimism.

What Is A Tens Unit Anyways
Transcutaneous electrical nerve stimulation is a nonpharmacologic treatment for pain relief. Using a low voltage electrical current, it safely and effectively can reduce pain, allowing you to live a better quality of life.
The TENS unit activates sites in the spinal cord and brain stem that utilize muscarinic, opioid, and serotonin receptors. This is with regular appointments, adequate dosing, and proper intensity.
For back pain, place the TENS unit electrodes on an area of skin over where there is some pain. Electrical Impulses travel along the nerve fibers, relieving pain immediately, also creating a tingly sensation. There is pain relief because the unit stimulates the nerves in the spinal cord, closing a gate mechanism which relates to pain sensation.
Does Tens Work For Sciatica
So how does TENS work? Its mechanics are all in the name. The unit sends gentle, electrical shocks through the skin in order to stimulate the nerves. The electrical shocks are not painful, as one might assume initially. Instead, many describe these gentle shocks as being a pleasant sensation similar to a massage, or a light tingling. TENS works in two ways to help relieve pain. The first step is to block painful signals from travelling through the nerves to the brain, replacing them with the massage-like tingling. The second function that TENS performs is stimulating the release of endorphins, the bodys natural painkiller. Together these actions ensure that when you use a TENS unit for sciatic pain you get powerful and immediate results.

What Are The Parts Of A Transcutaneous Electrical Nerve Stimulation Device And How Do They Work
The battery-powered TENS device is about the size of a small cell phone. The device comes with several sets of electrode wires and end pads. The electrodes connect to the device at one end and are attached to about 2 inch by 2 inch pads at the other end. Each pad has an adhesive backing and is positioned on your skin in specific areas along nerve pathways in the area to be treated.
The device delivers pulses of electrical energy. Pulses can be adjusted for intensity, frequency, duration, and type . A doctor, physical therapist, or acupuncturist determines and adjusts the machines settings.
Can I Overuse A Tens Unit
Other side effects from a TENS unit are often down to people not following the guidance and overusing the device or having the intensity set too high. Using the machine too much can make the area being treated sore. While using excessive intensity can make muscles twitch and result in unpleasant sensations.

What Conditions Does Transcutaneous Electrical Nerve Stimulation Treat
TENS is useful for chronic pain relief in patients with the following:
Skin reactions can often be avoided by keeping the gel pads sanitized and following good skin care. The other reactions are uncommon and can generally be relieved with over-the-counter medicines.
TENS should be used with caution on patients with skin allergies or diseases. It should not be used on a patient who
Side Effects And Other Drawbacks Of Tens
Before deciding whether or not TENS might be an appropriate treatment for yourself, you need to be aware of the fact that it does have some potential side effects. These include:
- Skin irritation, which around 33% of people experience. It is believed that this happens when the electrode gel dries out, however, which means it can be avoided.
- Skin reactions, usually caused by a reaction to the tape that keeps the electrodes in place. The use of self-adhesive electrodes can resolve this.
- Skin burns, which should only happen if the device is not used properly.
- Problems for those who have a pacemaker, so do check this with your physician
- Problems for those who are pregnant, as premature labor can be induced. Again, check with your physician whether you can use this therapy or not.

The Difference Between Tens And Ems
TENS units and EMS units are not the same devices. While both of these devices rely on small electric shocks, TENS units are meant to stimulate nerves, and EMS units are designed to stimulate muscles. So, EMS units are primarily used to help strengthen and tone muscles, but TENS units are solely used to manage pain.

How Do I Choose A Tens Unit
Choosing a TENS unit is not easy, especially if youre looking to secure the best possible model. Still, the best model for you may not be the best one for your neighbor. Your personal preferences and health needs will help you to determine which model is right for you, though there are a few additional features and factors to consider.
To turn a challenging purchasing experience into a fast and easy one, simply keep the following aspects in mind while searching for your new TENS unit.
Price
Depending on your budget, the price may either be a massively influential factor or barely an inconvenience. Still, its important to choose a TENS unit that adheres to your budget, and selecting a price range before browsing can help significantly.
Higher-priced units are often higher-quality, but this isnt always the case. Still, TENS/EMS units, fully-stocked kits, and advanced smart devices all tend to fall on the higher-end of the affordability spectrum.
Size
The size of the TENS unit can affect its portability, so if youre looking for an easy-to-wear system, a heavy control unit could quickly become a bothersome disadvantage.
Battery Type
Some TENS units are rechargeable and contain a long-lasting lithium battery. These units can last for up to three years, and theyre incredibly convenient and modern. Still, once these internal batteries kick the bucket, youll have to toss the entire unit out.
