Percutaneous Electrical Nerve Stimulation –
Electroacupuncture by Another Name?
A Comparative Review.

Summary
Percutaneous electrical nerve stimulation (PENS) investigation to determine whether there was any is a technique that has been described as a ‘novel difference between PENS and EA, and to bring analgesic therapy’. A review was performed of the the matter to the attention of the readership of published literature in order to compare PENS with the author’s knowledge and experience of the use of EA, specifically with regard to the Methods

The conclusion of the the Cochrane database was performed in February review is that PENS is neither different in 2001 using the search term ‘pens’. No other principle nor in practice from EA, and whilst the restrictions were applied to the search.

Biphasic waves tend to be the norm in modern EA, and the pulse widths most frequently used are around All the PENS trials use ‘acupuncture-like 0.2ms; however, these differences are unlikely to needle probes’ inserted to a depth of between 1cm have a significant effect on nerve depolarisation and 4cm. These probes were obtained from a in comparison with the current utilised and the Japanese company that produces acupuncture proximity of the needle electrodes to nerve needles.

Of course, EA is not a classical Chinese technique, as developing an electrical generator for PENS it was invented in the 1950s as an alternative to therapy.15 If such a device gains FDA approval, surgical anaesthesia, and whilst classical points they expect to receive direct financial benefits.15 are used, local segmental needling is also This reviewer was able to mimic the stimulation commonly applied. Moreover, segmental EA has parameters described in the PENS papers with a commercially available EA device (Cefar Acus Acupuncture Society courses for at least the last II), with the exception of the pulse width – a maximum pulse width of 0.45ms can be produced with the Acus II, rather than the 0.5ms described in the PENS papers.
