What is the duration of treatment for burst TENS?
Acupuncture-like TENS (AL-TENS) Low-frequency trains or bursts (2–4Hz) of high-frequency pulses (100–200pps) are often used in clinical practice.
What is conventional TENS used for?
The purpose of conventional TENS is to selectively activate large diameter non-noxious afferents (A-beta) to reduce nociceptor cell activity and sensitization at a segmental level in the central nervous system.
How long should a TENS unit treatment last?
Mostly, the pain relief will last from anywhere between 5 minutes and 24 hours. Typically, the level of pain relief will vary depending on the type of pain and the intensity of that pain.
How many types of TENS are there?
There are four varying types of TENS treatments, each offering unique properties to aid in patient healing and wellness. It's up to chiropractors to understand the difference between them and their efficacy across different situations.
What should be the frequency to apply TENS?
How Often Should You Use Your TENS Machine? You can safely use a TENS machine as often as you like. Usually for 30-60 minutes up to 4 times daily. TENS can provide relief for up to four hours.
How many Hz is a TENS Unit?
Conventional TENS has a high stimulation frequency (40-150 Hz) and low intensity, just above threshold, with the current set between 10-30 mA. The pulse duration is short (up to 50 microseconds). The onset of analgesia with this setup is virtually immediate.
What TENS unit settings work best?
Set the pulse rate to between 80Hz – 120Hz and a pulse width between 175uS – 200uS. For pain you have had for more than a few weeks (chronic or persistent pain) – use the 'modulation' setting to prevent your body getting used to the stimulation, which would make the unit less effective.
How often can you use a TENS unit per day?
Watch the time. In pure TENS mode, a TENS unit can be used for up to two hours per treatment, up to two to three times daily, in the same body area. For total spine pain —cervical, thoracic and lumbar— it would be feasible to use a TENS unit on each area for up to two hours at a time, Dr.
What is TENS plus EMS?
Transcutaneous Electrical Nerve Stimulation (TENS) machines stimulate the nerves exclusively for the purpose of relieving pain, whereas Electrical Muscle Stimulation (EMS) machines are designed to stimulate the muscles for the purposes of strengthening and rehabilitating them.
What are different TENS modes?
The different TENS modes include conventional narrow pulse duration, high pulse rate, low frequency, burst, modulation, and hyperstimulation. Use of conventional TENS results in a comfortable electrical paresthesia, whereas low-frequency modes result in rhythmic muscle contractions.
What's the meaning of TENS?

Is Tens a prescription drug?
Every pain killer, whether over the counter or prescription, has a specific safe dosage that should not be exceeded. However, TENS is not like these drugs at all. TENS is an extremely safe and non-invasive alternative to these pain killers.
Is it safe to use tens?
When you’re using a home-use TENS device as instructed, it’s safe to use TENS as often as you need. With that answer in mind, it may be that TENS is more effective for certain patients with more frequent uses. Remember, TENS also encourages the release of endorphins with each use, which work as the body’s natural painkiller.
Can you become addicted to Tens?
Since TENS does not enter the body in any way, it does not have what it takes to be addictive in any way. Therefore the answer the last of the sample questions above is simple. There is no limit to how much TENS one can use before becoming addicted because there is no addiction involved with TENS.

What is tens in medical terms?
TENS is the application of electrical current through electrodes placed on the skin for pain control. It can be applied with varying frequencies, from low (< 10 Hz) to high (> 50 Hz). Intensity may also be varied from sensory to motor intensities. Sensory intensity is when the patient feels a strong but comfortable sensation without motor contraction. High intensity usually involves a motor contraction but is not painful. In general, higher-frequency stimulation is delivered at sensory intensity, and low-frequency stimulation is delivered at motor intensity. Prior literature from our laboratory shows that, regardless of intensity, different frequencies activate central mechanisms to produce analgesia. Specifically, we show that low-frequency TENS activates μ-opioid receptors in the spinal cord and the brainstem, whereas high-frequency TENS activates δ-opioid receptors in the spinal cord and the brainstem [2–4]. Subsequent studies have investigated the role of serotoninergic, noradrenergic, muscarinic, and γ-aminobutyric acid (GABA)-ergic systems on the analgesia produced by both low-frequency and high-frequency TENS.
How does Tens produce analgesia?
It is generally thought that TENS produces analgesia by activation of cutaneous afferent fibers at the site of application . However, by differentially blocking primary afferents with local anesthetics, Radhakrishnan and Sluka [8•] showed the importance of deep tissue afferents in the analgesia produced by TENS.
Which receptors play a role in the analgesia produced by low frequency tens?
Peripheral opioid receptors also appear to play a role in the analgesia produced by low-frequency TENS. Sabino et al. [10] showed that blockade of μ-opioid receptors at the site of application prevents the reduction in hyperalgesia produced by low-frequency TENS but not high-frequency TENS.
How are experimental pain models used?
Experimental pain models have been used to retrieve useful information on electrophysical therapies prior to conducting full-scale, randomized clinical trials. However, their limitations must also be recognized in that they are unable to replicate the complex interactions between the physiologic and psychological processes of clinical pain. Five studies have been recently published on the effect of TENS on upper limb pressure, heat, and ischemic experimental pain models. Brown et al. [21•] failed to demonstrate any significant differences in pain relief in a crossover study using experimental ischemic pain when high-frequency TENS (100 Hz) was applied for 5 minutes at the painful forearm site compared with a remote nonpainful site. This study used a relatively short stimulation period compared with the other experimental pain studies.
Why is Tens controversial?
However, the effectiveness of TENS on individual pain conditions, such as low back pain, is still controversial, likely because of poor study designs and small sample size. Thus, continued research of TENS mechanisms and stimulation parameters in adequately characterized patient populations is critical.
Where to apply Tens?
The site of electrode application of TENS is typically at the site of injury. However, as central mechanisms are activated by TENS, it is possible that application outside the site may also be effective. Recently, two studies confirmed this hypothesis by showing that application of TENS to the contralateral hind limb reduces hyperalgesia of the inflamed limb [10,11•]. Furthermore, when hyperalgesia developed bilaterally after a unilateral injury, application of either high- or low-frequency TENS to the inflamed or the contralateral side reduced the hyperalgesia bilaterally [11•]. In a different pain model, Somers and Clemente [12] investigated the sites of electrode placement that would best prevent the development of allodynia in a chronic constriction injury (CCI) to the rat sciatic nerve. Repeated daily high-frequency TENS for 12 days with electrodes positioned on the skin covering either ipsilateral or contralateral paraspinal muscles reduced the development of mechanical hyperalgesia in CCI rats. Low-frequency TENS applied to acupuncture points in the ipsilateral or contralateral hind limbs decreased the development of thermal hyperalgesia, but only when TENS was delivered on the contralateral side [12]. Thus, once hyperalgesia develops, application of TENS to either the ipsilateral or the contralateral hind limb is effective.
How long does it take for a tens unit to work?
The onset of pain relief should occur shortly after the intensity setting has been determined. However, in some cases, pain relief may take as long as 30 minutes to achieve. TENS units are typically operated for long periods of time, with a minimum of 20 - 30 minutes and in some post-operation protocols, as long as 36 hours.
What is a Tens 3000?

Does tens work?
Transcutaneous Electrical Nerve Stimulation is a non-invasive, drug-free method of controlling pain. TENS uses tiny electrical impulses sent through the skin to nerves to modify your pain perception. TENS does not cure any physiological problem; it only helps control the pain. TENS does not work for everyone; however, in most patients it is effective in reducing or eliminating the pain, allowing for a return to normal activity.

How does Tens therapy work?
TENS therapy can ease pain by using electrical currents that block the pain signals from going to your brain. It only provides temporary relief, but it can benefit both acute and chronic pain. Acute pain should be treated with high frequencies of 80 Hz or higher, while chronic pain should be treated with low frequencies of no more than 10 Hz.
What is tens in medical terms?
TENS is an acronym for transcutaneous electrical nerve stimulation. It’s a type of electrical stimulation, also called e-stim.
How does a Tens machine work?
The electrical currents pass from the TENS machine to your body via electrodes. Electrodes are the pads that are connected to the machine with wires. They stick onto your body with adhesive, so the area needs to be clean and dry before you place them. Electrodes can either be self-adhesive or require medical tape.
What is pulse width on Tens?
Pulse widths are another setting you should be able to control on your TENS unit. This is the duration that the current is sent. Low pulses are shorter than moderate pulses.
What are the modes of a tens unit?
A TENS unit should have three different modes: normal, burst, and modulation. The modes control how the electrical currents are dispersed.
Can a Tens unit cause burns?
In TENS units, you should be able to set the frequency to the level you want to use. High frequencies can feel uncomfortable and cause skin burns. The sensation you get from a TENS unit feels like tingling. That tingling comes from the electromagnetic waves running through their cycles. So, the higher the frequency, the faster the cycle, and that’s what can cause irritation.
Can you harm yourself with a Tens unit?
While you can use them at home, you should check with your doctor or physical therapist before you begin to use it to make sure you use it correctly, so you don’t harm yourself. It’s possible to injure yourself with a TENS unit, which will be discussed in more detail in this article.
