Pain Relief With Portable TENS Units For Sale

Monday, January 9th, 2012

Portable TENS units are portable, battery-operated devices that are used to apply electric current to the skin in a bid to get relief from pain. TENS is an acronym of the technical name of this process——Transcutaneous Electrical Nerve Stimulation. Even though portable TENS units can be bought without a medical prescription, it is advisable to use one only when it is prescribed by a doctor.

TENS works by stimulating the nerves around a region of the body by the application of the electric current. This stimulation overpowers other types of activities of the nerves, including the generation of pain, with the result that the patient gets immediate relief from pain. Over the long run, TENS is known to give relief from chronic pain by acting indirectly on the central nervous system.
Applying TENS Using a Portable TENS Unit
Since portable TENS units are invariably operated by battery, ensure that your unit is charged fully before using it. TENS devices consist of a body and one or more electrodes that are connected to the body. Most TENS devices have knobs and other controls on the body, which allow the user to change the power and frequency of the electric current generated by the device. Once you have set the device at the frequency and power required for your session, place the electrodes on the region of your skin where you require relief from pain. A conductive gel is usually applied to the bottom of the electrodes to make them more conductive, and to reduce irritation to the skin. You can now start the device, switching it off when the prescribed time is over.
Since TENS works locally, it is very important to put the electrodes on the right spot on your skin. If you place the electrodes even a few inches away from the spot which is the center of the pain, you risk wasting the session.
Precautions and Side Effects
Individuals who use a pacemaker should not apply electric stimulation to their skin and body. Electric current can interfere with the working of the pacemaker, with possibly deadly results. This means they should not use TENS at all. Pregnant women should take counsel from their doctor before using a portable TENS machine. Individuals with a heart condition should also avoid using this device. Portable TENS unit should not be used on the head, especially across the forehead, unless you are using a specific setting as advised by your physician. Consult your doctor before you use any TENS unit.
Portable TENS units are a godsend for people who require respite from extreme or chronic pain. If you have been prescribed the use of such a device, you can use it at home, office or while on the move. If used with caution, and as long as you are not susceptible to any harm from electric stimulation, they do not have any discernible side-effects, especially in the short term. You can use a portable TENS unit by attaching its electrodes to the region of your body that requires relief from pain, and switching it on for the duration prescribed by your physician. Pain relief could not be simpler.

Home use of TENS units

Monday, October 24th, 2011

TENS unit therapy is easily one of the best ways to help ease pain. They are great because of their ease of use and portability; you can relieve your chronic pain at home. Most commonly, TENS units are used to treat injuries, osteoarthritis and chronic pain. You may have used a TENS machine if you have ever had physical therapy or been treated for pain relief at a chiropractors office. Home TENS use is a relatively new adaptation of technology. They are a safe and non-invasive way to relieve pain. I suggest getting approval as well as advice from a licensed physician.

Let’s look at the basics behind TENS. A TENS Unit relieves pain by sending electrical impulses by way of small electrodes placed on the skin. When used properly, it doesn’t hurt, if it does or muscles get to twitching, then the settings are too high. These electrical impulses send signals to nerve endings under the skin and on to the brain. The signal that gets sent to the brain reduces the feeling of pain and creates a tingling sensation. Many people use home tens units to reduce consumption of pain medication. Pain killers have multiple side effects, whereas, TENS units have none, so this makes them a healthier way to manage pain.

If you’re like me and are against using pain medicine, a home tens unit works great. My portable tens unit is small enough that you can use it in the car, on breaks at work, and pretty much anywhere. The portability of TENS pain relief is a huge advantage over traditional pain relief measures.

You can also choose a combination  with electrical muscle stimulation. TENS and muscle stimulators (EMS) are similar in that they both use electrical nerve stimulation to treat various injuries and conditions. Muscle stimulators work mostly for healing and rebuilding muscle. TENS is a way to temporarily ease pain. A TENS machine stimulates nerve endings and the muscle stimulator stimulates the muscle motor nerves. The combination of the two can’t be beat as far as cost and health; convenience and pain management are concerned.

Brands of Home TENS Units

Home TENS units are cost effective and can be used every day several times a day as needed. You will get plenty of use out of them and this one thing alone makes them cost effective. Prices start under $100 and go up to several hundred depending on features.

Lg Med Supply has a portable tens unit for $105 that combines both TENS and EMS. It comes with both battery and AC adapter, carrying case, belt clip, 8 programs, intensity control, pulse rate, adjustable pulse width and 3 year warranty. The warranty is 100% money back satisfaction and you can’t beat that. Rated 5 stars on Amazon with all positive reviews.

Lg Med Supply also has a home TENS unit- EMS combo for $80 that isn’t as strong in intensity as the one above with less features. It too, has all positive reviews with a 5 star rating, so if you want to compare the two just check them out on Amazon for more details.

Home TENS unit therapy is an excellent non-invasive method of pain management as long as you invest in a quality unit and use them as instructed.

Are TENS Machines Effective For Pain Relief?

Thursday, February 11th, 2010

One of the more popular drug free methods to control pain is the use of a TENS machine. TENS (transcutaneous electrical nerve stimulation) are available without prescription and safe and easy to to use. There are a wide range of machines available for home use ranging from a simple machine for pain at around $20 to more than $300 for a dual channel machines that also includes muscle stimulation functionality.

How Does a TENS Machine Work?

Electrodes are placed on the skin (hence the name transcutaneous) and the nerves stimulated by a small electrical pulse. At a high pulse rate this has the effect of blocking the impulses that transmit pain messages to the brain. In addition a low pulse rate can be used which stimulates the production of the body’s own pain suppressing hormones, endorphins. The hand held TENS unit is used to control the intensity of the impulses, the pulse rate and the time the stimulation is applied. It is usually recommended that the unit is used for twenty minutes to thirty minutes during which time the pain is blocked by the electrical impulses. pain relief however persists after switching off the unit due to the production of endorphins.

What Type of Pain Does a TENS Machine Block?

The most effective use of these machines is for the relief of chronic pain from joints, muscles or nerves and is not recommended for pain from other conditions such as appendicitis, hepatitis etc. For those with chronic pain that require strong drugs for relief TENS can be very effective and is a good alternative to increasing the level of painkillers required.

Can You Use TENS During Labor?

TENS is becoming increasingly popular as a non drug method to help control labor pain. The electrodes are placed on the back and the intensity controlled by the woman in labor. As the level of pain during labor increases the intensity of the stimulation can be increased accordingly giving her complete control. During labor the machine is often used in two ways. During a contraction a high pulse rate is used to block the pain and between contractions a lower pulse rate is used to stimulate endorphin production which in turn helps to lower the pain of contractions. TENS can be used right from the beginning of labor, before the pain has increased in order to stimulate endorphin production. This is more effective than waiting until labor is more advanced. One caution we should mention here is that the use of TENS machines before the 37th week of pregnancy has not been shown to be safe for the developing foetus so should not be used.

How Safe is TENS?

Using a TENS machine is safe provided you follow the safety guidelines. You should not use this method if you have epilepsy or have a heart pacemaker as the electrical stimulation can disrupt it. If you have pain then you should always consult a physician to diagnose the cause before you use TENS. It should not be used for pain from underlying medical conditions such as appendicitis or for anyone who has heart disease unless recommended by your physician.

Never use the electrodes:

  • In the mouth
  • on the groin
  • on broken skin or wounds
  • on each temple
  • close to the eyes or on the head
  • on areas of skin that are numb or desensitised

Conclusion

The use of a TENS machine is a safe, effective, non drug method of relief from chronic pain. Always make sure your pain has been diagnosed by a qualified medical practitioner before you use TENS and follow the safety guidelines that are issued with your machine.

Metal Implants and Tens Units For Pain

Wednesday, January 13th, 2010

Is there or should there be a concern for patient who have had metal implants inserted and then start using a tens or interferential unit?

This is a question that has been asked many times over the past half century as both the field of implant technology improved as did the field of electrotherapy for pain, rehab., and non union fractures. The question is a fair one to ask not only from a safety perspective but also from the other angle of does an implant enhance the efficacy of an external tens stimulator or interferential machine.

Basically the implant is outside the electrical field of a tens unit so there is no effect generally. Also many new composites for implants do not have metal or electrically conductive materials in them so over the next few years the question may become moot. Tens units are powered by a 9 volt battery and lack enough energy to penetrate deeply into the tissues but with the advent of Interferential for home use the chances of interference become more pragmatic.

A tens/tns unit emits no more than 150 pulses per second ( how many times the unit goes off and on per second - pps/rate/freqeuncy ) however an interferential unit has a pps between 8,000 and 8,150 pps with greater penetration. The higher frequency and greater output bring into play the depth of penetration issue and does an underlying metal object help or hurt the treatment.

Most tens and interferential devices are used principally for the control, or elimination, of chronic pain such as sciatica, RSD, neuralgia, phantom limb pain etc. The treatment with interferential though is for short periods of time due to the interferential unit providing ” carryover pain relief ” or residual pain relief. The interferential unit is not generally worn by a chronic pain patient, unlike tens which only provides relief while being used.

To date there are not any true safety issues brought on by the use of interferential or tens units with patients having implanted metal devices. The single issue has been does the stimulation cause any degree of discomfort to the patient while being treated and if so the practical answer is to move the electrodes so the implant will not interfere with the sensory relief provided by the interferential or tens unit. It’s possible if the pain area is near the implant that the conductivity of the materials used may actually enhance the pain relief.

When an interferential unit is used for home use it is generally assumed the short treatment period versus the continual treatment with tens lessens the potential of implant interference with an interferential unit.

TENS Pain Relief - What is Involved in TENS Pain Relief?

Tuesday, December 8th, 2009

What is TENS pain relief and how does it relate to someone in pain? TENS is an acronym for a transcutaneous electrical nerve stimulation unit. A TENS unit is a portable, pocket-sized, battery-powered device that uses mild, safe electrical signals to help control pain. One of these units can treat many kinds of pain. A modern TENS pain unit is easy to use and compact enough to provide quick and dependable pain relief at work, home or play.

The electrical signals travel from the TENS unit through wires to the electrodes which are attached to your body. The electrode wires are then plugged into the unit. The unit is then hooked to your belt or placed in a pocket. For some chronic pain patients, TENS pain relief can last for several hours. For others, a TENS pain unit may help reduce the amount of pain medications needed.

A TENS pain unit is one of several kinds of electrotherapy devices that use very small doses of electric current to promote natural pain relief. A typical battery-operated TENS unit is able to modulate pulse width, frequency and intensity. When the unit is turned on, it delivers a light current through the electrodes to the skin and tissues just beneath it.

The unit emits low - voltage electrical pulses through electrodes attached to the body. The TENS unit works by preventing pain signals from reaching your brain. Depending on the frequency the unit delivers, the electrical stimulation can also trigger the body to release endorphins, which are natural pain killers. A physical therapist can help you determine the most appropriate settings for your unit.

Do not turn your TENS unit up too high as this can cause over-stimulation which may make pain worse. Do not get into water or sleep with the electrodes on your skin and the TENS unit turned on. If you wear a pacemaker check with your physician before using a TENS unit as this may interfere with the pacemaker’s function.

TENS units can be purchased or rented. The cost of a unit can range from about $100 to several hundred dollars. A TENS pain unit should only be used under the direction of a doctor, physical therapist, or occupational therapist.

If you suffer from chronic back pain, arthritis, tendinitis, aches and pain, poor circulation, sciatic nerve pains, headaches, migraines and other discomforts a TENS unit may help relieve some of your pain. TENS pain relief is not a cure, it simply gives the impression of experiencing less pain. These units are widely used in the physical therapy field to help patients control their pain while they rehabilitate their muscles. TENS pain relief units are considered safe when used properly and have helped many people.
