What is Tens Therapy?

"Tens" stands for transcutaneous electrical nerve stimulation, which is quite a mouthful! Basically, it is a kind of therapy that uses low-voltage electrical current pain relief.

When the current is delivered many people report to experience less pain than usual. This is mostly likely due to the fact that electricity from the electrodes stimulates the nerves in an affected area and sends signals to the brain that "confuse" the pain signals.

Additionally, there is also a theory that the current helps produce natural painkillers.

This is because when the tens unit is turned on it delivers a soothing current through the electrodes to the skin and tissues located beneath the sticky pads. The optimal tens unit settings can vary, as it is such a highly customizable pain treatment, however, it should be set at about 100Hz and for one half hour for pain relievement.

What Does a Tens Unit Do for Muscles?

The tens unit delivers a soothing electrical pulse to the areas it is attached to. The proper placement of tens unit electrodes for pain would be to place the sticky pads on the part of your body that have the most pain.

But, tens units can be made affordable for all and most offer a free trial for 1-3 months to see if it would truly be worth it for you and your pain management plan.

Traditional TENS

  • Stimulation at a relatively high frequency (80 - 130Hz)
  • Short duration pulses
  • Less support for manipulation of the pulse width
  • Most patients seem to find best effect at around 200ms.
  • The stimulation is delivered at ‘normal’ intensity, meaning it isnoticeablebut in no way uncomfortable
  • At least 30-45mins to achieve pain relief
  • The main pain relief is achieved during the stimulation, with a limited relief after the machine as switched off

Acupuncture TENS

  • Lower frequency stimulation (2-5Hz)
  • Wider/longer pulses in comparison to other TENS units (200-250ms)
  • The intensity employed will usually need to be greater than with the traditional TENS-though it will be stronger it should not be uncomfortable
  • 30-45 minutes to achieve pain relief
  • Onset of pain relief may be slower than with the traditional mode
  • Many patients find that stimulation at this low frequency at intervals throughout the day is an effective strategy. The pain relief, after the machine is switched off, may last for several hours, but it will vary between patients

Brief Intense TENS

  • Can be used to achieve a rapid pain relief
  • The strength of the stimulation may be too intense for some and will not tolerate it
  • The pulse frequency applied is high (in the 80-130Hz band)
  • The pulse duration is also high (200ms plus).
  • The current is delivered at, or close to the tolerance level for the patient, meaning they would not want to turn the machine up any higher
  • It is suggested that 15 - 30 minutes at this stimulation level is the most that would normally be used.

Burst Mode TENS

  • The burst mod interrupts the stimulation outflow at rate of 2 - 3 bursts / second
  • The stimulation intensity will need to be relatively high, though not too high
  • It is proposed that the application of BURST mode TENS can effectively stimulate both the "pain gate" and the "opiod" mechanisms simultaneously.

Modulation mode TENS

  • The machine delivers a less regular pattern of TENS stimulation in an attempt to reduce or minimize the accommodation effects of patterned stimulation
  • Some vary the frequency, some vary the intensity and some vary the pulse duration
  • Research evidence does not favor one variation method over another
  • This potentially most useful for patients whouse TENS for hours a day
