TENS Machine Reviews: Does TENS Really Help?

A TENS machine review about the iTENS

TENS (Transcutaneous Electrical Nerve Stimulation) therapy is a drug-free solution for pain management. People with chronic pain may look at TENS machine reviews before getting a device. It works by sending electrical impulses through the skin to divert the pain signals. For most people, using a TENS device helps alleviate the discomfort. However, pain relief may vary between individuals. Some may feel the therapeutic effects instantly, while others take some time.

Doctors and physical therapists recommend TENS treatment to patients with acute and chronic pain. It is a natural and non-invasive method of pain relief without the common adverse risks of medications. Moreover, there are various considerations before getting a TENS device for personal or home treatment. This post will present how TENS works to relieve pain. It will also talk about what to look at in choosing a device and how to use it safely.

TENS Machine Reviews: How TENS Works

If you are considering TENS for pain management, it is important to know how it works and the benefits it can provide. Numerous TENS machine reviews also provide insight into the uses of the therapy for various conditions. First of all, a TENS machine is a portable device that produces low-voltage electrical currents sent to the nervous system. It utilises adhesive electrode pads attached to the skin to target the affected area directly.

The device uses varying levels of intensity and frequency to activate the body’s natural mechanisms against pain. In particular, high-frequency TENS stimulate the closure of pain pathways in the spinal cord. During the stimulation, the nerves that act as gate controllers block the transmission of pain signals going to the brain. In contrast, low-frequency TENS induces the production of endorphins, the body’s natural painkillers. Consequently, the brain processes fewer pain messages, resulting in decreased pain sensations.

You can modify a TENS machine to adjust the pulse rate and pulse duration based on the type of pain or severity. Moreover, it has preset modes for quick pain management. These programs have built-in settings according to body parts or ailments. Therefore, users have flexible options for pain control. The reviews about TENS units may vary depending on the efficiency, power, and features of the device.


TENS machines can provide the following benefits:

  • relieve symptoms of chronic conditions like arthritissciatica, tendonitis, fibromyalgia, and other disorders
  • boost blood circulation to the affected area
  • relax the sore muscles
  • facilitate faster healing of injuries and post-operative pain
  • improve mobility or the range of motion

Checking the settings before buying a TENS machine

TENS Machine Reviews: What to Check Before Buying

Good quality TENS machines require a reasonable investment. It is also vital in ensuring the effectiveness of pain management. Thus, many individuals read TENS machine reviews to know what other people are saying. Additionally, choosing a device may be overwhelming with the vast options available. Nevertheless, looking at essential aspects can make the purchase decision easier. These include the range of TENS settings, electrode types, features, and ease of use.

TENS machines utilise mild currents for nerve stimulation. However, the settings and features vary in each device. These involve the range of intensity settings, pulse rates, and the number of preset modes. A device can have 10 to 15 intensity levels or more for mild to extreme pain. The higher the number, the stronger the pulse. It is beneficial for treating severe symptoms. Additionally, more preset programs make the device versatile for pain management.

The reviews about TENS devices also prioritise ease of use and durability. This largely depends on the features of a TENS unit. Mainly, TENS comes in either wired or wireless electrodes. A standard device has lead cables connecting the adhesive pads. It also differs in the number of channels. On the other hand, wireless devices have Bluetooth capability to pair with a smartphone app. This makes pain management routines more convenient as there is no hassle of tangled wires.

Other Considerations

  • Battery type – single-use or rechargeable. Rechargeable TENS units are more cost and energy-efficient for long-term use. It also ensures it lasts a long time.
  • Extra features – TENS with massage and EMS (Electrical Muscle Stimulation) functions.
  • FDA clearance – ascertains the safety of the device.
  • Accessories – interchangeable pads in different sizes.

TENS Machine Reviews: How to Operate the Device

Some reviews of TENS machines may vary due to many factors. It is important to note that each person responds differently to TENS therapy. In addition, the effectiveness of TENS relies on the correct usage of the device. Before facilitating treatment, wash the skin to remove any lotion, oil, or dirt and pat dry. This helps the pads to adhere firmly. Afterwards, identify the most painful area and position the electrodes accordingly.

Next, turn on the device and start at the lowest setting. Gradually increase the intensity until you feel strong but non-painful impulses. The treatment duration will depend on the type of pain. The average session lasts for 30 to 60 minutes. You may consult a medical professional to determine the suitable settings for your condition. Moreover, you can customise the treatment or use preset modes. Lastly, turn the unit off before removing the pads after the therapy.

People with chronic pain can use a TENS device up to four times daily. However, always give a 20-minute break between sessions to let the skin rest. It is also advisable to alternate the placement of electrode pads to minimise skin irritations. Following the usage guidelines help individuals experience the benefits of TENS without risking any adverse effects. After checking the TENS machine reviews, you may get a device that suits your needs.

Safety Precautions

  • Do not place the TENS electrodes in sensitive areas, such as the head, neck, chest, and spinal column.
  • Avoid turning the intensity level so high that it causes muscle contractions.
  • Replace the TENS pads immediately when they lose their adhesion.
  • Do not apply the pads on irritated, infected, or broken skin.


There are many things to consider when choosing a TENS device for pain management. They vary in their range of settings and features. For example, you may get a standard wired or wireless electrode machine. This can impact the way you manage pain. Moreover, taking the time to consider these factors and reading TENS machine reviews can help you make an informed decision. Therefore, you can get a TENS machine that meets your needs and use for a long time.

To help get the most effective pain relief, it is vital to follow the TENS machine usage guide and safety precautions. Additionally, you may consult a healthcare professional to ensure that TENS is the right treatment for you. For instance, TENS is not suitable for use by people with heart conditions, epilepsy, and pregnant women without medical advice. You may buy a TENS machine, like the wireless iTENS, online without a prescription.
