A TENS battery-powered device delivers alternating current via electrodes that are placed on the skin around the painful area. Most devices allow you to set the pulse frequency and intensity. The stimulation activates a complex neural network in your body, providing an analgesic (pain relieving) effect and relieving your pain.
Full Answer
What is the pulse rate of a TENS device?
Pulse Rate: The pulse rate is the rate in which pulses are sent from the TENS device. Pulse rates are registered in hertz or pulses per second. The pulse rate chosen depends significantly on the electrode placement.

How does tens affect the peripheral nerve system?
Abstract. Basic science studies using animal models of inflammation show changes in the peripheral nervous system, as well as in the spinal cord and descending inhibitory pathways, in response to TENS. Translational studies show mechanisms to prevent analgesic tolerance to repeated application of TENS.
What is the pulse rate on a TENS unit?
TENS machines are thought to work in two ways: On a high pulse rate of 90-130 Hz (the normal method of use), the electrical impulses generated by the TENS machine interfere with and block pain messages sent to the brain.

Can you use TENS machine with high blood pressure?
TENS produced no significant effect on BP, regardless of intensity. Discussion: These results affirm that high levels of intensity are of fundamental importance in effective TENS dosage. This also applies for low frequency, segmental stimulation. Resting BP seems not to be dependent on intensity.
Can TENS lower blood pressure?
Another possible approach is by transcutaneous electrical nerve stimulation (TENS), a non-invasive method that modulates activity by inhibiting primary afferent pathways using low-frequency transcutaneous electrical stimulation. Some studies have shown that TENS reduces blood pressure in patients with hypertension.

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.
What is sensory intensity?
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.
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.
