What kind of current does a TENS unit use?

A standard TENS unit typically delivers a low-frequency (<50 Hz) alternating current to a focused treatment area. Due to the nature of low-frequency, however, these signals have a low capacity to overcome skin resistance – resulting in these units only providing pain relief via the Gate Control Theory while being worn.

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).

Is TENS a low-frequency current?

The International Association for the Study of Pain (IASP) describes conventional TENS as “High-frequency (50–100 Hz), low-intensity (paraesthesia, not painful), small pulse width (50–200μs)” (4).

What are the best settings for a TENS unit?

Setting the Pulse Rate (Frequency) Acute pain is usually most effective between 80 and 120 Hz. Chronic pain can also benefit from lower settings 2 to 10Hz that stimulates an endorphin release. A setting between 35 and 50Hz is commonly used to stimulate muscles for strengthening or even relaxation.

Where are the electrodes located in the TENS unit?

A TENS unit consists of a battery-powered device that delivers electrical impulses through electrodes placed on the surface of your skin. The electrodes are placed at or near nerves where the pain is located or at trigger points. Cleveland Clinic is a non-profit academic medical center.

How big are discount tens large electrode pads?

Discount TENS Large Electrode Pads. Suitable for any TENS unit with industry standard 3.5mm snap connector, these hand-shaped pads are a more cost-effective option. Measuring 3″ x 1.77″, the Discount TENS Large Electrode pads are available for purchase as ten pairs (a total of 20 pads).

What should I put on my TENS unit?

When a patient is using a unit at home, it’s important for them to follow the recommendations of this TENS Unit Electrode Placement Guide, but also follow the directions of their healthcare practitioner. 1.Skin must be clean and dry. 2.Put a thin coat of gel on the bottom of each electrode.

How does transcutaneous electrical nerve stimulation ( TENS ) work?

TENS © Tim Watson (2016) Page 1 TRANSCUTANEOUS ELECTRICAL NERVE STIMULATION (TENS) INTRODUCTION TENS is a method of electrical stimulation which primarily aims to provide a degree of symptomatic pain relief by exciting sensory nerves and thereby stimulating either the pain gate mechanism and/or the opioid system .
