Transcutaneous electrical nerve stimulation is widely used for acute and chronic pain management.
Areas of use include obstetrics, temporomandibular joint pain, and postoperative pain.
The main therapeutic effects of TENS include. pain relief through the gate control theory or the endogenous opiate pain control theory
TENS units are portable and indicated for home use.
Conventional TENS Frequency: 50 – 150 Hz
Conventional TENS Duration: 20 – 100 microseconds
Conventional TENS Amplitude: 10 – 30 mA
Acupuncture-like TENS Frequency: 1 – 4 Hz
Acupuncture-like TENS Duration: 100 – 200 microseconds
Acupuncture-like TENS Amplitude: 30 – 80 mA
Pulse burst TENS Frequency: 70 – 100 Hz / burst
Pulse burst TENS Duration: 40 – 75 microseconds
Pulse burst TENS Amplitude: 30 – 60 mA
Brief intense TENS (high-intensity) Frequency: 70 – 100 Hz / burst
Brief intense TENS (high-intensity) Duration: 150 – 200 microseconds
Brief intense TENS (high-intensity) Amplitude: 30 – 60 mA
this chart is to be used as a guideline for overall understanding of the mechanism of action behind each type of TENS and its outcome based on those settings.
The waveforms used are monophasic pulsatile current or biphasic pulsatile current with a spiked square, rectangular or sine wave form.
Electrode placement may be based on sites of nerve roots, trigger points, acupuncture sites or key points of pain and sensitivity.
Net polarity is normally equal to zero. If the waveform is unbalanced there will be an accumulation of charges that will lead to skin irritation under the electrodes.
