8 Best TENS Units & 2019 Best Selling Portable Models on Amazon

Ever happened while exercising or during lifting weights that a muscle gets stiff and causes uncomfortable and restricted movement? Or the Arthritis taking over and not letting sufficient movement to happen? Well, we need to learn that the human body is a machine that is both, strong as well as delicate. What you feed it, it develops like that and how you take care of it is how it flourishes.

The most usual way to temporarily stop the pain from arthritis is by consuming pain killers. In cases where joints have incurred damage and have lost ability to move, surgeries are performed on them.

A Transcutaneous Electrical Nerve Stimulation (TENS) machine functions by delivering a tingling sensation on the skin. This can help to block or suppress pain messages that are sent to the brain. TENS Units stimulates the body to produce higher levels of a naturally occurring painkiller, known as endorphins. Endorphins are chemicals that are secreted when the body experiences pain. TENS Unit appropriately allows pain reduction without posing the potential side effects that are usually experienced during a medications’ course. A TENS unit can be used during a physical therapy session or can be used at home. It is a cost-effective treatment for pain relief that delivers results with minimum side-effects. For such an intricate and wonderful device, let us check out the 8 best TENS Units available on Amazon:

Buying Guide To Tens Units 

What is a TENS Unit and how does it work?

TENS is short for Transcutaneous Electrical Nerve Stimulation. It is a safe and non-invasive method of stimulating nerves by introducing low intensity electrical signals to the surface of the skin, the affected area. As it can be used to stimulate a wide range of nerves in the body, TENS has a very diverse range of uses. One of the most common uses of TENS being reducing chronic pain caused by ailments like Arthritis, injuries, accidents etc throughout the body. It can also be used to even potentially enhance athletic performance.

We need to learn that the human body is a machine that is both, strong as well as delicate. What you feed it, it develops like that and how you take care of it is how it flourishes. The stiffness, pain or soreness as experienced is due to excess accumulation of lactic acid in muscles. The body produces lactic acid in the form of lactate, in the absence of oxygen. The muscles then consume this compound to energize itself during exercising.

Cartilage is a firm yet flexible connective tissue in the joints. It protects the joints by absorbing the pressure and shock created during movement that can cause excessive stress on the joints. A reduction in the normal amount of this cartilage tissue causes forms of arthritis.

The other form of machine that is used to provide relief from such pains is known as Electrical muscle stimulation or an EMS. TENS is low volt stim while EMS is high volt stim. It doesn’t require a powerful machine to create enough voltage to stimulate the nerve fibers. The principle science behind TENS is called Gate Control theory. The experience of pain depends entirely on the central nervous system working in coordination with the peripheral nervous system. Pain is sensed and originates in nerves around damaged tissue and the signal of ‘pain’ travels via the peripheral nervous system to the spinal cord and finally to the brain. Before these pain messages reach the brain, they go through several “nerve gates” present in the spinal cord that open or close depending upon the nature of instructions coming from the brain. While the gates are open and intense sensation of pain is felt while if the gates are closed, little or no sensation of pain is felt. The activation of different types of nerve fibers can either modify or block the sensation of pain. The TENS unit is set to activate certain fiber types that perform this block function. The action of blocking the nerve is related to the voltage-frequency the TENS is set to and can be thought as continuous “thumping” or “tapping” of the nerve.

Eventually the nervous system begins to neglect the message and the pain experience dulls down or even gets turned off. There are many studies that discuss this phenomenon of pain suppression.

EMS is high volt stim that is used in the devices to stimulate muscles in order to make them strongly contract which strengthens them. For instance a person with knee injury who had surgery in the past may have a very weak adductor and this leads to imbalance in the knee as the stronger outside muscles pull on the knee is greater than the internal resistance offered by the inner part of the leg. Using EMS on the inside adductor muscle in an on/off manner improves the muscles by strengthening them even when the patient is recovering from a surgery and cannot take part in activities that include movement. The history of EMS dates back to time when Russian Olympic athletes started utilizing EMS to massively stimulate muscles in order to make them powerful. These contractions are hardly tolerable On the other hand, TENS can provide pain relief from lower back pain while EMS may relieve painful muscular tension.

TENS Unit appropriately allows pain reduction without posing the potential side effects that are usually experienced during a medications’ course. A TENS unit can be used during a physical therapy session or can be used at home.

Are there any side effects of TENS Therapy?

The TENS Therapy is quite new to the science world and its advantages over any other machine have taken over the world by storm. Many researches are still going to better understand benefits potential side effects. The device works by introducing low intensity currents into skin receptors via electrodes. Now these electrical signals may interfere with other electronic devices planted in the body and cause malfunction.

The other reported side effect has got nothing to do with electronic circuit in the device but rather the pads (that act as electrodes). If the adhesive gel on the pad gets too sticky, it will be hard for the user to take the electrode out after use. Whereas, if the adhesive gel is not strong enough, it will not hold to the skin during therapy. It is also advised not to use conductive gel as it will malfunction with the electrodes.

TENS, EMS: Beats Pain

The stiffness, pain or soreness as experienced is due to excess accumulation of lactic acid in muscles. The body produces lactic acid in the form of lactate, in the absence of oxygen. The muscles then consume this compound to energize itself during exercising. Cartilage is a firm yet flexible connective tissue in the joints. It protects the joints by absorbing the pressure and shock created during movement that can cause excessive stress on the joints. A reduction in the normal amount of this cartilage tissue causes forms of arthritis. The most commonly reported Arthritis forms are Osteoarthritis, Rheumatoid Arthritis and Psoriatic Arthritis. Typical wear and tear as a result of excess stress and pressure causes Osteoarthritis. An infection or injury caused during initial days of Osteoarthritis’ buildup can exacerbate the natural breakdown of cartilage tissue. The risk of developing Osteoarthritis (OA) gets higher if there has been a family history of the disease.
Another common form of arthritis, the Rheumatoid Arthritis (RA), happens as a result of an autoimmune disorder. It occurs when the body’s soldier immune system attacks the tissues of the body itself under the impression that the tissues are foreign entities and need to be eliminated. These attacks affect the synovial. The synovial lines and protects entire inner surface of the joint, except where the joint is lined with cartilage. It is a soft tissue that lubricates the joints whereas, it nourishes the cartilage.
Psoriatic arthritis affects some people who have psoriasis, a skin condition that causes appearance of red patches on the skin topped with silvery scale formation. This form of arthritis is usually diagnosed after Psoriasis. It happens as a result of an autoimmune disorder. It occurs when the body’s soldier immune system attacks the tissues of the body itself under the impression that the tissues are foreign entities and need to be eliminated.
The other variant of machine that is used to provide relief from such pains is known as Electrical muscle stimulation or an EMS. TENS is low volt stim while EMS is high volt stim.

Things to keep in mind while buying a TENS unit

Since the TENS Unit is no longer a prescription device, it is important to first understand the working mechanism and determining whether if the device is actually a need.

Here are the things one should keep in mind while buying a TENS device:

The power potential and Modes:  When selecting a device, you must be sure that the power level is acceptable to your needs. A wide range of power is recommended as every body part is different with respect to sensitivity experienced.

Users may find that certain modes work well for certain types of pain. Finding the perfect mode may not be an option but having multiple options available to the user, makes the experience much more enjoyable.

Battery and TENS electrode pads’ Life: A lithium ion battery is the ideal battery type. With high quality lithium battery the user can get weeks or even a month of usage before having to recharge the batteries again.
