Frequently asked questions (FAQ) - TENS

General information about the TENS treatment

How does a TENS treatment work?

TENS stands for transcutaneous electrical nerve stimulation. In TENS therapy, skin electrodes are placed on or next to the painful area and connected to a stimulation current device. The stimulation current device sends electrical impulses, which are transmitted through the electrodes to the nerves. The electrical impulses cause an increased release of pain-inhibiting messenger substances in the body and blood circulation-promoting substances are formed. The transmission of pain to the brain is interrupted and inhibited by the pulses. TENS therefore offers a non-invasive, drug-free pain relief. The TENS treatment can be applied to almost all body regions (from foot pain to headache). Learn more about the exact procedure of a TENS device.

Does TENS help in pain relief and against muscle tension?

The mild electrical impulses of the TENS devices can reduce the pain signals that go to the brain and release pain-inhibiting messenger substances. Thus, pain can be relieved and muscle tension can be released.

Which parts of the body can be treated with TENS?

With a TENS device you can treat pain in almost all parts of the body (from foot pain to headache). Here you will find a detailed overview of all TENS applications.

Does the TENS treatment promote blood circulation?

An increase in skin temperature was observed during TENS treatment in patients with chronic pain in the extremities. It is therefore assumed that TENS increases blood circulation, leads to a better supply of nutrients and thus accelerates the healing of various wound types.

How long does the effect of a TENS treatment last?

The pain-relieving effect of TENS after stimulation can last between five minutes and 18 hours. Since pain-inhibiting messenger substances can be released by TENS, the pain can be suppressed for a longer time.

Does a TENS treatment also relax strained muscles?

According to studies, TENS helps to relieve pain caused by muscle knots, muscle tension, muscle soreness and spasms. The endorphins released by the therapeutic TENS devices can also help to relieve pain. With both TENS and EMS treatment, you can reduce pain caused by muscle knots while improving mobility.

You can perform a therapy session up to three times a day. During each therapy session, rate your pain before and after the session from 1 (low) to 20 (high) to track the actual pain relief.

How long should one use a TENS device?

The success of treatment should be decisive for the frequency of use of the TENS device. As long as you do not feel pain relief from the stimulation current, there is no reason for longer breaks. Your body gives you a good feedback on how often you should perform the treatment. Please consult a doctor or physiotherapist for a consultation.
