Health herald digital therapy machine not working

Having issues with your TENS machine? Then fear not, we’re here to help. Most of the time it’s usually the smallest thing like, putting the batteries in correctly or even turning up the intensity. So here are a few tips on what to do if you’re having problems…

Make sure the batteries are inserted correctly into the machine as directed by the instructions.
Change the batteries. They could be either not working at all or only have a little juice left in them resulting in the output of the TENS machine not giving out the right intensity.
Unplug the lead wires and switch the unit on to see if the power indicator light comes on.
Try switching the lead wires around on the different channels as the problem could be resulting in just one channel not working.
Try connecting a new set of lead wires.
Try connecting a new set of electrode pads.
Press the mode button and turn the intensity up slightly to test if it could be a certain mode not working.
Make sure that the whole electrode pad is placed firmly on the skin. The best way to test this is by placing them on your forearm.
When testing, units that have two prongs coming out of the lead wire must both be connected to two pads as the unit will not work with one pad.
Check that the end of the lead wires are connected firmly into the unit and the prongs of the lead wire is connected firmly into the electrode.

Uses

Share on Pinterest

TENS units can help treat and manage pain.

TENS units may help treat the following symptoms:

period pain
labor pain
postoperative pain
joint pain
neck and back pain

They may also alleviate pain that results from the following conditions:

endometriosis
arthritis
sports injuries
multiple sclerosis
fibromyalgia
painful diabetic neuropathy
spinal cord injury

A TENS unit has controls that allow people to administer an appropriate level of pain relief. People can achieve this by altering the following aspects of the electrical current:

Intensity: A dial allows the user to adjust the intensity of the electrical stimulation.

Frequency: The frequency refers to the number of electrical pulses per second. High-frequency (HF) pulses range from 80 to 120 cycles per second and may help manage acute pain. Low-frequency (LF) pulses range from 1 to 20 cycles per second and are suitable for the treatment of chronic pain.

Duration: The duration is the number of microseconds that the current enters the skin for during each pulse.

Benefits

TENS is a noninvasive method for relieving pain. People who experience pain relief from TENS may be able to reduce their intake of pain medications, some of which can be addictive or cause adverse side effects.

TENS units are also convenient because they are small, portable, and relatively discrete. People can carry a TENS unit in their pocket or clip it onto a belt to ensure that they have immediate access to pain relief throughout the day.

Possible side effects

Share on Pinterest

If the adhesive pads cause redness or irritation, hypoallergenic pads are available.

It is safe for most people to use a TENS unit, and they will not usually experience any side effects.

However, the electrical impulses that a TENS unit produces may cause a buzzing, tingling, or prickling sensation, which some people may find uncomfortable.

Some people may be allergic to the adhesive pads. Anyone who experiences skin redness and irritation can switch to using hypoallergenic ones instead.

It is vital never to place the electrodes on either the front of the neck or the eyes. Putting electrodes on the neck can lower blood pressure and cause spasms. On the eyes, the electrodes can increase pressure within the eye and possibly cause an injury.

When to avoid TENS

Although it is safe for most people, experts recommend that some groups of people avoid TENS treatment unless a doctor advises its use.

This recommendation applies to the following people:

Pregnant women: Pregnant women should avoid using TENS in the abdominal and pelvic regions.
People with epilepsy: Applying electrodes to the head or neck of people with
epilepsy

may induce seizures.
People with heart problems.
People with a pacemaker or another type of electrical or metal implant.

Does it work?

Due to a lack of high-quality research and clinical trials, researchers have not yet determined whether TENS is a reliable treatment for pain relief.

One study found that TENS treatment provided temporary pain relief for people with fibromyalgia while the machine was in use.

While there is a lack of strong clinical evidence for its effectiveness, TENS is a low-risk pain relief option for many people.

Several factors may influence the effectiveness of TENS:

Tolerance

Research shows that people who use a TENS unit on a daily basis at the same frequency and intensity can develop a tolerance to the treatment.

A person who develops tolerance will no longer feel the same level of pain relief that they did when they first used the unit.

To prevent this from occurring, people can alternate between LF and HF TENS within each treatment session.

Alternatively, they can gradually increase the intensity or duration of TENS on a daily basis.

Stimulation intensity

The range of intensities of the electrical stimulation may account for some of the differences in research findings.

According to a 2014 review, HF TENS treats pain more effectively than LF TENS. In fact, many studies have found LF TENS to be ineffective.

Given that HF TENS is a more effective pain reliever, experts recommend that people apply the highest-intensity TENS that they can tolerate.

Electrode placement

TENS may be more effective if people place the electrodes on acupuncture points.

Acupuncture is a practice that uses needles to stimulate the nerves beneath the skin at specific locations known as acupuncture points. Experts believe that this assists the body in producing endorphins.

One review found some evidence that people who receive TENS through acupuncture points may experience a reduction in pain.

How long does pain relief last?

A person who repeatedly uses a TENS unit may build up a tolerance.

The duration of pain relief after using a TENS unit can vary. Some people report that their pain returns as soon as they switch off the device. Others continue to experience an adequate level of pain relief for up to 24 hours.

A 2012 review suggests that the duration of pain relief increases after repeated TENS treatments. However, this repetition can also increase the likelihood of a person building up a tolerance to the treatment.

Takeaway

The research on using a TENS unit for pain relief has so far yielded inconsistent results due to a lack of high-quality scientific studies and clinical trials.

Some research suggests that TENS treatment can relieve pain, but this may be dependent on certain factors, such as the affected area of the body and the treatment intensity. Knowing how these factors affect TENS can help people use it more effectively.

Most people can use a TENS unit safely, and few will experience side effects. However, it is best to speak to a doctor before trying TENS either as an alternative treatment or in combination with other methods of pain management.

TENS units are available to purchase at some pharmacies and online.
