Acupuncture PENS


PENS :  Percutaneous Electrical Nerve Stimulation

Percutaneous electrical nerve stimulation (PENS) is a contemporary form of electroacupuncture guided by principles of neuroanatomy and neurophysiology that has been shown to have immediate efficacy for reducing pain younger patients with low back pain (1) 

One of the originators of PENS treatments, Dr. William Craig, preferred to use neuroanatomical references to guide his applications of needle electroacupuncture stimulation, rather than acupuncture point theory or classical acupuncture. 

PENS is therefore often referenced to an alternate description and theory of application, that of neuroanatomy. There also may be insurance coding that specifically refers to PENS, not electroacupuncture.

In practice, and from an instrumentation and electronics standpoint, the normal PENS device is essentially identical to electroacupuncture devices.  There may however, as is typical in bioengineering, be some overlap and lack of consistency in terminology, and FDA classifications. 

Pantheon Research PENS devices were designed and built in close consultation with Dr. William Craig,  and the 9c3i device specifically was created with his specifications for the “ideal PENS” device. 

This machine incorporates the unique capability of having three separate modules or frequency sections, in operation simultaneously, thus allowing three separate frequency protocols to be administered to the  patient for pain treatments[JH1]  at one time. 

This was according to Dr. Craig’s specifications.  He has stated: “The Pantheon machines are the best PENS devices on the market”.   Following his research,  he concluded that multiple frequencies introduced at the same time, were best for chronic and acute pain conditions. 

Our 9c3i was built on this conceptual foundation.

The Pantheon Research PENS devices, the 12c.Pro and the 9c3i are built to all the exacting standards of our 4c.Pro and 8c.Pro electroacupuncture equipment, namely:

  • Manufactured to the highest quality, professional and scientific standards
  • FDA certified after meeting their stringent testing protocols
  • Calibrated to an accuracy of 99.94%
  • Unique electrical microcurrent waveforms

As far as patient treatment is concerned, you can expect to give your patients the best treatment available in the market today:

  • You can calibrate frequencies to provide your patients with the most comfort during treatment
  • Our unique microcurrent waveforms (industry exclusive) ensures the most effective treatment
  • Our built-in safety mechanisms (industry exclusive) prevents patient accidents
  • The mixed mode feature allows for optimal pain treatments, including the lower back
  • Overall better machine performance leads to delighted patients
  • Delighted patients make more referrals; people love to spread the word when relieved of pain they have been suffering through for years after electro acupuncture treatment

Here’s where our PENS machines can help in your clinic or practice: 

  • Long operational life with little to no maintenance
  • Reduced downtime and patient rescheduling based on reliability
  • Ability to self-test to ensure equipment is performing to specifications – industry only
  • Money-back performance guarantee: guaranteed to 99.94% accuracy – industry only
  • One-year warranty – (can be extended to 10 years) – industry only
  • High return on your investment: one-time up front cost and minimal costs thereafter
  • Unparalleled support: 24/7 support from within the US and Canada - industry only
  • Multiple internal safter features to prevent electronic malfunction, such as current limiting resisters that are redundant – industry only
  • Device cannot be turned ON unless all output knobs are first turned OFF; prevents accidental shocking of patients – industry only
