Often the terms "pain" and "chronic pain" are confused by many people, including those who are empowered to treat the conditions.

   Pain is the natural reaction of our body to a stimulus such as a bee sting, twisting an ankle, touching a hot pan, or an over dosage of ultraviolet light resulting in sunburn.  In most situations it's an impulse that requires some defensive maneuver to prevent further damage.  If it's touching something hot we withdraw the extremity to avoid further burning of tissues, or infection due to bacteria entry resulting from the burn.  If it's a delayed reaction to overexposure to sunlight we should not go back out and sunbathe as our body has signaled no further exposure or more pain will follow.

   Chronic pain is not a natural reaction, it's unnatural.  Humans are not created to experience pain.  The absence of pain is the natural state not the endurance of pain.   The term "chronic pain" has crossed the path of being a natural occurrence to that of being an unnatural occurrence however many people suffer from this diagnosis and are ignored because of confusion between the two terms.

   Pain is not a diagnosis but symptomatic of an occurrence.

  The term "pain relief machine" is a very confusing phrase and it's understandable how people can not differentiate a "muscle stimulator" from a "tens unit" to an "interferential unit" or "pulsed galvanic stimulator" or a "micro amperage stimulator".

    Four of the 5 listed units are actually intended to be used for the treatment of chronic and acute pain.

   On the internet the following terms are searched on and the patient often gets some reference to a "pain machine" as a solution and then the confusion really begins.

* neck traction
* sciatic nerve pain
* sciatic nerve pain relief
* back pain relief machine
* pain relief machine
* sciatic nerve treatment
* painreliefmachine.com
* sore neck stretches
* stretches for sore neck

  Of the 5 machines listed the only one that is not intended for pain relief is a "muscle stimulator" which should be correctly called a "functional electrical stimulator" - FES.  The purpose of a muscle stimulator is to help a patient restore function or prevent atrophy to muscles. All of the listed "pain machines" can literally be adjusted to the point that a muscle contraction can be elicited but that is not the purpose of a "pain machine".

  There are basically three methods of controlling pain that each of the pain machines relies upon.

1. Melzack/Wall Gate Control Theory:
  This is simply the process of stopping the transmission of the pain impulse to the spinal cord for transmission to the brain where the pain is perceived.  The method of operation is to stimulate non-pain fibers so the actual pain message is not transmitted and the pain impulse is not transmitted. When that happens the brain does not receive the message therefore there is no pain. In reality though for the chronic pain patient the actual results are less transmissions rather than 100% total cessation meaning pain reduction, not total pain elimination.

2. Sjolund Opioid Peptide Production ( Pain Killers)

  In this application, which rarely ever works, the actual pain fibers, c fibers, are stimulated for 20 - 30 minutes and that stimulation by the pain machine results in the brain increasing the production of pain killers, aka endorphins and enkaphlins are the general terms used. As long as there is an increased amount of the peptides in the blood stream then the pain is not felt. As the peptides wear off and decrease in total volume then the pain reappears. This is not theory but has been proved however as stated earlier this application rarely is effective for the vast preponderance of chronic pain patients.

3. Glial Dysregulation of Pain and Opioid Actions

  This is very recent, appearing in research being done by Linda Watkins, PhD. - Univ. of Colorado - Boulder. Her work involves the blocking of pathological pain by inhibiting glial activation in the spinal column where the glial cells exist. The glial cells actually release many neuroexcitatory substances which can lead to pain amplification.

  The latter explanation helps to clarify what is now occurring with the use of interferential pain machines, unlike the other tens, micro, PGS machines where there is no carryover or residual pain relief once the pain machine is turned off.  With interferential therapy using the Infrex Plus there is residual or carryover pain relief during and following the treatment for hours or in some situations days/weeks. Glial cell inhibition may explain the effects of portable interferential units as well as replicate the clinical interferential treatments.

How Much Does The Infrex Plus Cost? 

Answer:  $1,695.00

Option 1.  MedFaxx will bill your insurance, if you have, and generally accepts what the insurance company pays.

  "I would love to have a free trial but have no insurance, and limited funds, so my big concern is the Infrex helps me and then I can't afford it."

Option 2.  MedFaxx will work with you on a payment plan that fits your budget.   We are well aware of the high costs of health care and understand the difficulties.   We live in the same world as you do.   Over the 3 decades of our existence we have had many patients in the same circumstances yet they received their unit and we worked with them for payment and also for the supplies needed.

   Here we have an interesting video on the use of Yoga for foot pain.   For many pain patients the posture adjustments due to pain result in secondary pain situations.   The most common may well be radiating sciatica resulting from low back pain.  The subsequent change of walking/standing/movement patterns put additional pressure on the leg and sciatica results.

   This video demonstrates for foot pain how the pain can be reduced or eliminated.


   Just released in the Journal of Pediatric Surgery, Volume 44, Issue 2 on pages 408- 412 is the result of a study done using interferential therapy ( IFT) for children with slow transit constipation.  The study is titled,

"Decreased colonic transit time after transcutaneous interferential electrical stimulation in children with slow transit constipation"

  We've reprinted the abstract below for your perusal.   Contact the Journal of Pediatric Surgery for the full study.

       Dr. Giovanni De Domenico, adviser to MedFaxx, actually detailed this procedure in his book,
 "New Dimensions in Interferential Therapy.  A Theoretical & Cinical Guide"  in 1985.   Dr. DeDomenico set out the protocol and the theory behind this form of stimulation for abdominal organs using interferential therapy ( IFT).   This is a short description of Dr. De Domenico's findings as they apply to adults.

   " Abdominal organs are controlled by the autonomic nervous system, in particular by the parasympathetic system. This system is largely responsible for regulating the movement and function of the gut and bowel.  If the sympathetic activity to a particular abdominal organ is suppressed, then this would leave the parasympathetic supply to that organ relatively unopposed and in this way, the function of the affected organs might be enhanced.  Inhibition of sympathetic nervous system activity is claimed to ocur at higher frequenceis, providing these fibres are located relatively superficially. " 

   In Dr. DeDomenico's above example higher frequencies refers to 80 - 150 hz ( CPS - cycles per second ).   With the ability to premodulate or mix the electrical current in the interferential unit only two electrodes may be needed however 4 can be used.   The treatment protocol is:

  • high, wide, rhythmical fast sweep in the 80 - 150 hz range
  • intensity is relatively low so only slightly perceived, if at all
  • there is to be no muscle contractions
  • duration ...............
  • total treatments should be ........... the treating frequency above

     The protocol described has been used to successfully treat chronic constipation with the electrode placement on the anterior abdominal wall. 

      Much of the theory of using interferential for pain involves stimulation to suppress the actual pain impulse.  In the above protocol we once again see the efficacious effect of the IFT is suppression of an ongoing signal of the sympathetic system so the effect of the parasympathetic is stronger and the efficacious result of suppression is beneficial treatment of chronic constipation.

Idiopathic slow transit constipation (STC) describes a clinical syndrome characterised by intractable constipation. It is diagnosed by demonstrating delayed colonic transit on nuclear transit studies (NTS). A possible new treatment is interferential therapy (IFT), which is a form of electrical stimulation that involves the transcutaneous application of electrical current. This study aimed to ascertain the effect of IFT on colonic transit time.


Children with STC diagnosed by NTS were randomised to receive either 12 real or placebo IFT sessions for a 4-week period. After a 2-month break, they all received 12 real IFT sessions—again for a 4-week period. A NTS was repeated 6 to 8 weeks after cessation of each treatment period where able. Geometric centres (GCs) of activity were calculated for all studies at 6, 24, 30, and 48 hours. Pretreatment and posttreatment GCs were compared by statistical parametric analysis (paired t test).


Thirty-one pretreatment, 22 postreal IFT, and 8 postplacebo IFT studies were identified in 26 children (mean age, 12.7 years; 16 male). Colonic transit was significantly faster in children given real treatment when compared to their pretreatment NTS at 24 (mean CG, 2.39 vs 3.04; P ≤ .0001), 30 (mean GC, 2.79 vs 3.47; P = .0039), and 48 (mean GC, 3.34 vs 4.32; P = .0001) hours. By contrast, those children who received placebo IFT had no significant change in colonic transit.


Transcutaneous electrical stimulation with interferential therapy can significantly speed up colonic transit in children with slow transit constipation.

 Neuropathic Pain and Acute Pain Are Always In the Head

                               "The Pain Is In Your Head"

    What a ridiculous and non caring statement to make to a chronic pain patient.  Not only that but also a very pedantic statement totally lacking understanding of how pain is transmitted in patients.

     Pain is a perception that is perceived in the brain.  In most situations it is a very good warning to prevent further harm or injury to the body.  An example of this type perception is heat when one touches something hot that can destroy tissue, create a burn, and allow for penetration of bacteria and other pathogens into our body in the exposed area.  At the moment of touching the hot item we do not know it is hot and destructive.  Through a series of electrical and chemical reactions the process goes to the brain and there the brain will instruct defensive reactions by another set of chemical and electrical signals to our muscles to "fire" ( no pun intended (:) ) or create motion to remove the area from the heat.  That is good.

    However with the chronic pain patients the stimulus is not generally a one time cause but could be the result of injury, accident, or surgery. More difficult is neuropathic pain, a result of injury or disease to the peripheral or central nervous system.  The pain is ongoing and can be ever present for that patient.  Examples of neuropathic pain are:

  • distal polyneuropathy
  • mononeuropathy
  • mononeuritis
  • radicular
Multiple Sclerosis:
  • trigeminal nerve
  • mutliple nerve roots
  • either one side or half of the body
  Neuropathic pain is often present in amputation and known as phantom limb pain, or in some patients who have suffered a stroke, in Guilian-Barre and in chronic diagnostic conditions such as fibromyalgia, restless leg sydrome, or reflex sympathetic dystrophy.   It is now believed that due to the neuropathic diseases that a new disease can develop as a result and the disease is "chronic pain". 

    The neuropathic diseases are progressive physical and chemical changes occurring in the body and if left unchecked develop a disease process of their own.

    It does not matter  if the pain is of neuropathic genisis, or from actute injury, the perception of that pain always occurs in the head, the ultimate receptor site for painful stimulus.  

    Certain medications help on very narrowly focused receptor sites in our body to allow or inhibit chemical changes.  Each of those chemical changes are predicated upon the ions of certain chemicals having specific electrical charges, either a positive or negative polarity.  If the polarity in the painful stimulus area is changed then the chemical changes can not occur and hopefully with chronic pain patients the pain processes can be inhibited.   The constant polarity changes found in interferential therapy ( IFT) are bringing new understanding to pain control and also the therapeutic results of longer, extended carryover pain relief periods are beginning to show the clinician there can be  underlying physical changes that will prevent the transmission of pain impulses to the brain and the pain cycle is broken.

   Out of fairness to all chronic pain patients the familial retort to the painful state should not include the statement, "the pain is all in your head".  A better retort would be "I'm not sure what is causing the pain but my job is to help you eliminate it or lessen the severity of the pain you experience." 

   Compassion coupled with understanding is needed.

Interferential For Carryover Pain Relief for Neck Arthritis - Cervical Spondylosis
Neck Arthritis

    Cervical spondylosis, often referred to as "neck arthritis", is a common degenerative condition of the cervical spine and may be associated with mineral deposits in the cushions between the vertebrae. Clinically it manifests itself with symptoms such as neck and shoulder pain, suboccipital pain and headaches, radicular symptoms such as shooting pain down the arms.

   In advanced stages it symptomatically manifests itself by:
