TENS unit sessions are typically between 20 – 30 minutes long because that's how long it takes for most people to get pain relief. It's possible that it will take longer for you, and it's possible to use it for up to 2 hours at a time depending on the TENS unit. How Often to Use a TENS unit
Full Answer
Can tens be used to treat chronic pain?
TENS therapy can be used to treat both chronic (long lasting) and acute (short-term) pain. The most common conditions that TENS therapy is used to treat are: Osteoporosis-related joint, bone, or muscle problems Fibromyalgia-related joint, bone, or muscle problems.
What is the duration of tens treatment?
TENS is a non invasive tool to assist with pain relief. Regular application of the TENs machine can result in reduced pain for up to 4 hours following use. TENs is considered a pain relief tool and not considered curative. The degree of pain relief declines with prolonged use; vaiation of electrode placement may combat this.
What conditions can be treated with a TENS unit?
Some of the most common conditions for which TENS has been used include: Osteoarthritis (disease of the joints). Fibromyalgia (aching and pain in muscles, tendons, and joints all over the body, especially along the spine.
Are TENS machines effective for fibromyalgia?
Emerging evidence suggests TENs may be helpful for peoples with fibromyalgia and spinal cord injury. TENS may be effective in restoration of central pain modulation, a measure of central inhibition.
How long should you use a TENS unit each time?
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 long is too long for TENS?
Can you overuse a TENS unit? TENS stimulation should last for only 30 minutes at a time. After this, a 20-minute break is advised to give your skin a break for potential skin irritation from using TENS in one area on the skin for too long.
How long does a TENS session take?
You can begin with one 15-minute therapy session. Repeat for another 15 minutes if needed. Use up to three times per day at a maximum. During each therapy, rate your pain before and after the session, 1 (low) to 10 (high) in order to gauge the true reduction of pain.
How long should you use electrical muscle stimulation?
Depending on the type of e-stim, you may feel a muscle twitch or contract repeatedly. Each e-stim therapy session may last 5 to 15 minutes, depending on the condition being treated.
Is it possible to use a TENS machine too much?
TENS is safe, so you can use it as much as you like, although it's good practice to take regular 10-minute breaks every hour or so. Some people use TENS for more than five hours a day.
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.
When do you use a TENS unit?
When is it best to use TENS? Research has shown that TENS is most helpful for chronic pain when used for at least 30 minutes while you are active. It is less effective when you are sitting still, lying down, or resting.
Do TENS units relax muscles?
When the machine is switched on, small electrical impulses are delivered to the affected area of your body, which you feel as a tingling sensation. The electrical impulses can reduce the pain signals going to the spinal cord and brain, which may help relieve pain and relax muscles.

What is pulse duration in electrical stimulation?
Pulse width refers to the length of time each group of pulses of stimulation is set to, measured in microseconds (us); or milliseconds on devices offering EMS for peripheral nerve damage (ms). It is common to see EMS devices offering ranges between 200-300us.
How often can you use EMS?
1-2 times per weekBefore you consider how many you need, it is important to understand that the maximum amount of times you can train using Electrical Muscle Stimulation (EMS) technology is 1-2 times per week. This is to allow time for your muscles to repair and recoup before your next session.
At what frequency does neuromuscular stimulation begin to diminish?
Later work by Bigland-Ritchie, Jones, and Woods (1979) showed that higher frequencies of stimulation (50 Hz and 80 Hz) administered to hand muscles resulted in a rapid decline in force after approximately 20s.
How to increase conductivity of Tens unit?
Make sure to clean and dry your skin before attaching the electrodes. This will increase conductivity, increase the lifespan of the TENS unit electrode pads, and decrease skin irritation.
How long does a pain relief session last?
How long your sessions last will depend on how quickly you see pain relief. It takes a while for some people, while others report getting relief nearly immediately.
Can tens units be used in different sessions?
The instructions that come with your TENS unit will probably say something similar, but it's possible that they recommend different session lengths. You should always read the directions for each device before using it.
Can you move around while receiving tens?
If you want to be able to move around while receiving the treatment, you'll definitely want to look into wireless portable TENS units. Wireless TENS units provide pain relief in the same manner as regular units, but they run on a battery.
Is a wireless unit good for pain?
Also, wireless units typically aren't as powerful and a regular unit. This is ok for moderate pain, but those with severe pain might find them unsatisfactory. It would be nice if everyone could use the same settings and a particular length of time worked for everyone, but that's not the case.

Bursitis (inflammation of the fluid-filled sacs that cushion joints).
What are the factors that affect the efficacy of Tens?
The factors affecting TENS efficacy include the population and the outcome assessed, timing of the outcome measures, negative interaction of opioid use and the parameters of the TENS dose. Three important factors for TENS efficacy are tolerance to repeated TENS, intensity of the stimulation and electrode placement. A recent article by Sluka et al.[43] provides an extensive review of variables that can affect the clinical use of TENS.
What is tens in medical?
Transcutaneous electrical nerve stimulation (TENS) is an inexpensive nonpharmacological intervention used in the treatment of acute and chronic pain conditions. These small battery-powered devices deliver alternating current via cutaneous electrodes positioned near the painful area. The parameters of pulse frequency, and pulse intensity are adjustable and linked to TENS efficacy. This article will provide a critical review of the latest basic science and clinical evidence for TENS. We will summarize mechanisms of action, factors that influence TENS efficacy, and describe and critique the use of TENS for pain control in a variety of patient populations. Findings of systematic reviews of TENS for pain management in the last 7 years will be presented. We will also highlight advances from Randomized Controlled Trials (RCT) published in the last 5–7 years, which are not included in the systematic reviews. This article offers a concise review of the basic science mechanisms for TENS as well as an up to date critique of current clinical research for TENS.
How does Tens work?
TENS activates a complex neuronal network to result in a reduction in pain. At frequencies and intensities used clinically, TENS activates large diameter afferent fibers [1,2]. This afferent input is sent to the central nervous system to activate descending inhibitory systems to reduce hyperalgesia. Specifically, blockade of neuronal activity in the periaqueductal gray (PAG), rostral ventromedial medulla (RVM) and spinal cord inhibit the analgesic effects of TENS showing that TENS analgesia is maintained through these pathways [3–5]. In parallel, studies in people with fibromyalgia show that TENS can restore central pain modulation, a measure of central inhibition [6]. Therefore, TENS reduces hyperalgesia through both peripheral and central mechanisms.
Do HF and LF TENS reduce dorsal horn neuron activity?
In animals without tissue injury, both LF and HF TENS reduce dorsal horn neuron activity [18–22]. In animals with peripheral inflammation or neuropathic pain, enhanced activity of dorsal horn neurons (i.e., central sensitization) to both noxious and innocuous stimuli is reduced by both HF and LF TENS [23–26]. In parallel, there is a reduction in both primary and secondary hyperalgesia by both LF and HF TENS [23,25–31]. Furthermore, in people with fibromyalgia and osteoarthritis, there is a reduction in pressure pain thresholds not only at the site of stimulation, but also at sites outside the area of application [6,32], implicating a reduction in central excitability.
Is Tens effective for neck pain?
There have also been systematic reviews on the methodology of TENS [77,78]. As a whole, these reviews are conflicting with some showing efficacy and some showing no efficacy for the use of TENS. The challenge is often a lack of high quality studies or a lack of consistency between high-quality studies included in the systematic reviews with respect to clinical population homogeneity, dose of TENS (i.e., location of TENS electrodes, frequency and intensity of TENS stimulation, and frequency and duration of TENS delivery), description of blinding and the influence of analgesic medication. Table 1represents a summary of these systematic reviews. Below we address the evidence on post-operative pain, acute non-postoperative pain, low back pain, osteoarthritis pain and painful diabetic neuropathy as examples.
Does HF TENS release glutamate?
HF TENS also reduces central neuron sensitization [24], and release of the excitatory neurotransmitters glutamate and substance P in the spinal cord dorsal horn in animals with inflammation [33,34]. The reduction in glutamate is prevented by blockade of δ-opioid receptors. Thus, one consequence of activation of inhibitory pathways by TENS is to reduce excitation and consequent neuron sensitization in the spinal cord.
Does HF TENS affect LF?
Both HF and LF TENS have effects at the site of stimulation. HF TENS reduces substance P, which is increased in dorsal root ganglia neurons in animals after tissue injury [33]. Blockade of peripheral opioid receptors prevents the analgesia produced by LF, but not HF TENS [35,36]. Thus, TENS may also alter excitability of peripheral nociceptors to reduce afferent input to the central nervous system.
What is TENS?
A TENS machine is small -- about the size of an iPad mini. It’s connected to a series of electrodes, which are put on your skin to deliver a low-voltage electrical charge. The electrical pulses stimulate nerve fibers in the area where you have pain and reduce the pain signals to your brain. The electrical charge may also cause your body to release natural hormones that decrease your pain levels.
Why don't you use tens?
Don’t use TENS in an area where you have numbness or less feeling, because you could burn yourself.

Is Tens stronger than Tens?
There are several different ways of delivering the TENS electrical current. Lower-intensity TENS may be less effective at relieving pain than higher-intensity TENS. Some experts recommend that TENS should be given at a strong, but still comfortable, intensity -- the highest intensity that does not cause pain.
Is it safe to use a Tens unit?
It’s generally considered safe, with fewer side effects than some other types of pain relief. There have been some reports of people getting mild electrical burns when they use their TENS unit improperly. So you should learn how to use a TENS unit with supervision from an experienced doctor or physical therapist.
