Spinal Cord Simulators ( SCS) for certain chronic pain conditions are picking up momentum as an invasive surgical option for the treatment of chronic pain. Some diagnosis that tend to respond well to a SCS implant are:

  • Cervical Radicular Pain - Chronic Neck Pain
  •  Lumbar Radicular Pain - Radiating Back Pain
  • Peripheral Neuropathies - Pain and numbness in hands and feet
  • Ischemic Peripheral Vascular Disease - severe obstruction of the arteries which seriously decreases blood flow to the extremities (hands, feet and legs) and has progressed to the point of severe pain and even skin ulcers or sores.

  Historically due to the costs, risks, and being invasive the industry itself has had to promote the benefits of undergoing an implant for pain control.  One of the reasons the process has been beneficial is the electrodes are surgically implanted around the spine and the electrical interference, vis a vis Melzack/Wall Gate Control Theory, now distribute electricity in the neural pathway.   One of the reasons for surgical intervention is the process

Positives and Negatives Regarding purchasing a portable tens or interferential pain machine out of pocket or having the insurance company buy it for you.


There are a variety of factors, both in support of and against, although the vast preponderance of the evidence does support using the insurance benefits that have already been paid for. There is little evidence to support "double paying". Well before paying out of pocket, it will be important and vital to make sure you know and fully grasp these pros and cons. This article explains some of the important plusses and minuses associated with using insurance benefits versus paying out of pocket. It will be important to you to fully understand these so that you can be able to make the most effective final choice in your case.

Advantages: Points In Favor Of purchasing a portable tens or interferential pain machine out of pocket.


1. Generally the cash or credit card cost is less when insurance does not have to be processed.


The cost of billing can often double or triple the costs of a company supplying medical products. In the case of Medicare compliant billing, the company has several costs of producing paperwork with the physician office and the labor, submission costs can easily be over $70 per unit.

2. The device can be mailed or delivered to the home or office, whereas the traditional delivery method has been in the clinic or physician office.

If the unit is provided in the mail then the patient does not have to schedule an appointment, take time off and pay an office visit fee.

3. Consumer Refund Protection When Using Credit Card

Another good reason for paying out of pocket is if a credit card is used and the product is defective then there is consumer protection offered by the credit card company in case a refund is due yet the company will or did not stand behind their product. Credit card companies usually offer refunds and the patient is protected by the use of the credit card to purchase the tens or interferential unit

This provides the added advantage of dealing directly as the payor with the company, rather than the payor being an insurance company, that can make it difficult to request a refund when the refund would be issued to the insurance company and not the patient..

4. The patient chooses who to purchase from and not the insurance company.

Often the insurance company may dictate what, and from whom, the device may come from without regard to the instructions, service, and dependability of the company.

And then there is the issue of how long has the company been around and will they still be there if a problem arrives or supplies are needed. That is critical as it may happen that the patient is in need of assistance yet the company has folded. The patient's insurance may now not cover a new unit since there was a provision within the contract permitting only 1 unit per year, or every 5 years, and even if a unit can be procured the process of getting approval can take forever, or it seems that way if the patient is in pain. Whenever you take that into mind, then it makes sense to use insurance benefits versus paying out of pocket. If the insurance company is not prompt then the option of out of pocket may make more sense.

The points above show the positive aspects of purchasing a portable tens or interferential pain machine out of pocket. There is a bad side too. Let us consider some of the negative aspects.

Negative Aspects: Arguments Against purchasing a portable tens or interferential pain machine out of pocket.

1. Most insurance policies provide for "durable medical equipment" which is what an interferential or tens unit is classified as.

The monthly premiums that were being paid entitles the patient to the reasonable costs for the unit. Any out of pocket costs are truly an "add on" to costs that were paid for and should be covered.

If you ever purchase a portable tens or interferential pain machine out of pocket, that might produce the effect of not having the supplies such as tens electrodes, batteries, tens replacement cables, rechargers, AC adaptors, not covered as there would be no record of the insurance company ever purchasing the unit therefore there will be no coverage for the tens supplies needed to maintain continual operation. There is no way that that could be a good thing. It could be enough reason for avoiding doing it at all.

2. The cost of ancillary supplies for chronic pain such as Tiger Balm patches, arnica patches, Sombra, BioFreeze, FlexAll, DMSO are not covered.

Those supplies are generally covered by insurance, including Medicare and some state agencies such as Medicaid, that are used for the condition the interferential or tens pain machine was prescribed for. This would also include skin care products in case the adhering electrodes cause some minor skin irritation to the patient.

3. The company that many insurance companies purchase from, especially Medicare and the state funds such as Medicaid, have to be ACHC accredited.

This means the companies have paid for, and been thoroughly inspected and accredited on issues such as patient privacy, patient rights, good manufacturing processes, compliance with regulations, and inspected to see that customer complaints and needs are adequately resolved. If the company is not accredited, or loses it's accreditation, then Medicare and many other insurance companies will not approve any purchases from that company.

4. The last valid reason to avoid out of pocket payment for the pain machines is you are literally "double paying" for benefits already paid for.

Also the cost of the tens unit is really not the cost of the unit itself, but the cost of the supplies needed, and one forgoes the benefits of the tens accessories and skin cream products in the future. That out of pocket cost can be many times over the cost of the original unit. With tens and the possibility of constant use, versus interferential with short 20 - 40 minute treatments often weekly or every 2-4 weeks, the electrode costs alone can be exorbitant. Interferential electrodes are best if they are somewhat larger than the standard tens electrodes. With insurance the patient can have both types electrodes for use and not have to pay for them separately, especially when the unit purchased was a combination tens and interferential unit.

Everyone ought to think about this point very carefully, because it can cause undue financial hardships if you determine to pay out of pocket anyway.

That is it, the actual pluses and minuses of purchasing a portable tens or interferential pain machine out of pocket or having the insurance company buy it for you. So it may not be what everyone wants and needs. Even so it will suit and help many. It is best to now look at the points made above and choose if this is right for you. This info should really assist you to be ready for making the proper decision.

How to Treat and Recover From Whiplash Or Neck Pain Injury
By Bob G Johnson

How To Treat Whiplash, Neck Pain In 3 Easy Steps


Many people experience some form of neck injury and its very painful. Often the injury, if it involves a car crash from behind, is referred to as whiplash. This type injury usually involves a sudden jolt of movement forward and the muscles immediately become inflamed and swell, guarding starts as part of the inflammatory process. The first 12 to 24 hours are generally not as severely painful as the time period following the acute onset. It is after the initial trauma the pain can become unbearable. During the first acute episode, following the trauma, its best to ice, cool the neck area because the body has responded to the trauma and initiated a series of chemical reactions to stop the harmful effects. The problem is inflammation, swelling, which began with the influx of new chemical reactions. Because the excess fluid is captured in the tissue area there is an expansion of cells and eventually a rupture in the cell walls themselves which will later require repair to gain full function. After the swelling has stopped then warm moist heat is a very good option to begin dealing with the inevitable pain that follows. Here are some practical remedies in 3 simple steps...

Step 1 - Ice Down/ Chill

The initial step to be taken is ice, cool down the neck injury area. You will need to do this because the muscles will start swelling and there will be a build up of cellular fluids resulting in cell/tissue destruction. Some of the destruction will be the result of the traumatic injury but there will also be additional damage due to the inflammatory response of the immune system. You will need to carefully avoid treating with heat during the acute phase, as the heat will increase blood flow and increase the swelling and tissue damage..

You will need to do the chill initial step promptly. If you do it promptly, then the swelling will subside and there will be less damage and less pain.

Step 2 - Apply Warm Moist Heat

Your second step is going to be after the first 12 - 24 hours, when the swelling has subsided, then begin warm moist heat for the pain. If you dont have a moist heat pad then simply use warm water on a towel and apply to the neck area. If possible in order to extend the heat of the towel you can put a piece of reflective aluminum foil over the top to contain the heat and not allow it to evaporate. Things you'll want to avoid here are be careful of using pain medications that may leave you sleepy or groggy. To heal its not necessary to basically "drug oneself" out of awareness. You should stay away from driving a car or getting in any situation where a quick movement, or the need for a quick movement reaction, can harm you. Many chronic injuries are merely acute injuries recurring over and over.

Step 3 - Use Electrotherapy, preferably Interferential therapy, with moist heat if possible.

The 3rd step is if possible use a portable interferential pain machine in conjunction with the moist heat packs or if interferential is not available then use a standard TENS unit. This will be significant because moist heat provides carryover pain relief until the area treated loses the heat. After the thermal heat effects are lost, the pain often returns. The interferential treatment is known as the therapy of choice for extending the residual or carryover pain relief time period, however TENS, transcutaneous electric nerve stimulators, can be worn continuously minimizing pain. This is important because if the carryover period is extended the muscles can be rehabilitated sooner, the pain upon stretching and doing the rehab. is minimized, and full range of motion is restored.

The exact steps outlined above should help the whiplash patient experience less pain, gain mobility quicker, and tissue repair conclude sooner. Just stick to the steps in order, for the reasons as explained, while carefully avoiding the traps, problems and potential mistakes mentioned. Then pat yourself on the back and enjoy the benefits and rewards of having lost the pain, restored the function and lessened the rehabilitation time.

How do I decide on a Tens or an Interferential Unit and what is the difference between tens & interferential therapy?

What is a Tens or Tns machine?

Transcutaneous Electric Nerve Stimulator (TNS) is a small lightweight portable device that goes off and on from 1- 150 times per second, which is referred to as frequency or rate, pulses per second ( PPS).

The tens pain machine can be worn continuously, even sleeping with it on to help the patient sleep. A Tens machine is not addictive, nor like drugs, does it affect ones mental abilities to think and reason. Often if the Tens machine is turned off the pain comes back. There is no residual pain relief generally speaking when one uses a Tens unit. Fro many patients the tens pain machine may be worn continuously.

What is Interferential?

Interferential machines go off and on from 8,001 to 8,150 times per second.

   There are a lot of good, quite recent products coming in the marketplace every week. Many of the products are in the medical industry as a result of cost containment and better treatment outcomes. Some of these are very promising and are worth an additional look. Some of these have distinguished themselves amongst their users, and are now being spoken well of around the medical forums and are also growing rapidly in user acceptance. Among those that are looking really good within the product category of non drug treatments for pain relief, is one called interferential pain machines, IF, or interferential therapy..

   This useful product type is the brainchild of many years of work to bring the most used form of electrotherapy out of the clinic and to the patient at home or work. In lieu of paying $35 to $100 per 12 - 20 minute treatment the patient can now buy one unit, use frequently self treating to stop pain or prevent the recurrence of pain. What interferential pain machines do is allow the patient to self treat wherever necessary whether at home, work or when traveling.

   The operation of scheduling a future Doctors visit to get an interferential treatment is basically a guessing game as to when/if the pain will reoccur and when it will happen. Often the treatment is not predicated upon the pain patients' condition but upon the availability of time in the future or upon the insurance company policy on allowances for office visits. Neither of these approaches has ever been in the patients' best interest.

   With the advent of self treatment to prevent pain, not treat pain, a new paradigm of treatment, pain prevention, has emerged that is more cost effective to the patient and insurance company.

    Rather than a patient having to take off work, which costs money to the patient, and hope an appointment for a clinical treatment of interferential will be done, the patient now takes a portable unit with them and can treat as needed. Over a one month time frame the cost per treatment can easily drop to a few dollars per treatment and also prevent the recurrence of pain in many cases. The new interferential therapy treatment is more cost effective than the use of drug medications and does not require continuing usage.

    No longer must a patient wait to hurt and then seek help or guess at the next "pain episode" but now its stop the pain cycle and skip the "start hurting, get treatment" cycle.

   Absolutely nothing is perfect, including interferential pain machines, but since this form of treatment has been around since 1953 as an exclusive treatment for health practitioners, it is now possible for the patient to self treat and make their own determination to the efficacy.

   Possibly the main drawback to the interferential pain machines is how to use them effectively. It is one thing to have the Doctor/ practitioner demonstrate, assuming the practitioner knows the correct procedure, but now with the advent of internet learning anyone can be taught. The use of video has changed the instructional component of using medical devices with outstanding results for patients. What information not learned, or forgotten, can be constantly watched in the videos or if necessary by text on web sites, blogs, Facebook Fan pages etc. No longer will a patient have to depend upon whether the practitioner really knows how to use a certain product but now the patient can be self taught and taught correctly on the specific device. Setup is easy with interferential units simply requiring turning on, simple adjustments to fit the pain of that moment, and electrode placement. A video can move the process step by step at anytime, any day for any patient that needs additional instruction and at no additional cost.

   The bottom line here is that interferential pain machines have an excellent history loaded with 1000's of successes from chronic pain patents treated in clinics. A fast-growing new client list is emerging with the advent of improved technology for self treatment becoming available. If any patient is actively in pain, it might be worthwhile taking a closer look at this new line of products for pain control and prevention, maybe even test one. That there are so many happy clients over the last half century can seldom be wrong...

   You will find all the details at Google search by simply typing in "interferential therapy", or "interferential video" on YouTube search and learning of the non narcotic pain remedy of interferential pain machines that are 100% safe and non addictive or harmful.


A video showing the clinical unit in site and the portable unit with discussion available at:


    Electricity has been used for generations for health reasons. An original use was an electrical charge could create life like responses and the most famous was Galvani who applied an electrical charge to a dead frog's leg and it would "jump". What was this magical force? It was a static charge and when the frog leg was touched the electrical charge stimulated the dead muscle tissue. Since Galvani there have been multiple uses of electricity to maintain or restore health in people.

    Today the same principle is used to establish if a nerve has been severed or is dead. A direct current electrical charge is supplied to test if the charge can go from the point of stimulation to the point of detection. An example would be applying a charge at the shoulder to see if the charge can be detected at the wrist. This helps determine if there is "healthy innervation". If no heightened electrical charge is detected then the clinician goes closer to the point of stimulation testing to find where the charge is lost. Chances are excellent there is disease or destruction at this
point. This process helps determine if rehabilitation is possible or not.

  For decades an electrical charge, described as "high voltage" or preferably "pulsed galvanic stimulation", has been used to make bed sores, decubitus ulcers, heal. The tissue in the open wound is gray, or if dead, necrotic, and the wound is not healing. A simple 5 - 20 minute charge is applied to start or accelerate the healing. Upon the body being stimulated to repair itself the wound bed turns red/pinkish from the increase in blood vessels transporting oxygen and nutrients to the area and healing resumes. The same phenomena is observed using tens units or interferential therapy units to facilitate healing.

  Today the same type phenomena is being used to jump start stem cells to replicate body parts, also has been observed to start the process of cell division for new life creation from the combining of sperm and embryo. The magical ingredient for many beginnings of cell division is a small electrical charge.

   Another use of the same electrical phenomena has been to make bones heal, unionization. The typical incident where electrotherapy is used is the motorcycle crush accident where the leg bones are crushed in an accident. The leg is exposed to a car and the impact splinters the bone. After cleaning and setting the bones are not healing. In the past if the fracture does not heal and the leg is not functional then amputation was the result. Today a "bone growth
stimulator" may be used and is generally very successful if the patient had/has the proper nutritional content to allow the body to heal the bones. The practice of using electricity, such as the bone growth stimulator or interferential unit, has become so commonplace that often many different orthopedic bone repair procedures involve the application of some form of electrical device to increase the growth rate and decrease the rehab. time while also protecting the patient against new injury. When healing increases there is less harm of further or future injury. This is especially true with neck injuries and the cervical bones need to heal as rapid and functionally as possible.

  One of the first uses of electricity was for pain control. The disease, trigeminal neuralgia, is often referred to as the "suicide disease" due to the pain becoming so unbearable that the patient had rather die than live in such misery. During Roman days there are records of patients suffering from this and the remedy for treating this excruciating pain was to put an eel in a bowl of water and have the patient then put their face into the bowl. The eel emitted an electrical charge, this was a reaction to the possibility of food for the eel and the reaction was to "stun the prey" so the eel could eat. The electrical discharge from the eel in the water also produced a sensitizing effect after the initial pain of the electrical discharge had worn off, and the patient was pain free for some time period.

   Today the time period is referred to as "carryover pain relief" or "residual pain relief" and is the amount of time after interferential therapy stimulation a patient goes before, or if, the pain returns. Today the use of interferential machines, often referred to as pain machines, tends to increase the carryover pain relief time period by giving the patient the ability to treat when needed. With the freedom to treat as needed, which is before the pain really starts, then the pain is never allowed to start.

   For as long as there have been humans on this earth there has been the use of electricity to aid the body in healing and to stop pain. Today with the advanced materials and knowledge of how to regulate electricity from a machine to the body, advanced concepts are emerging that are benefiting human health and eliminating human suffering.

  One of the most recent advantages has been the ability for patients to have FDA approved electrical medical devices, such as interferential and tens machines and self treat as needed. Many of the primary fundamental causative agents for positive medical results comes from a basic understanding of electrical charges and how our body uses those charges needed and disposes of those not needed. It is characteristic of our daily food intake where we often consume foods that are inherently bad from a nutritional point of view, yet as long as we consume enough of the necessary nutrients our body continues to live, heal and avoid disease . And also the body uses the right foods and discharges the junk food with it's unhealthy ingredients.

  Next, our body seems to work the same way with positive and negative electrical charges by using the negative or positive charges as needed while allowing the opposite polarity to pass through and be discharged. It's truly amazing of the resiliency of the human body and the ability to heal itself when given the electrical nutrients needed.

  Time and time again the phenomenon of electrical charges causes positive change for our daily living and health.

   Just consider it. Maybe, just maybe, with the advent of inteferential units combined with tens units we've reached the point for many innovative therapies with devices that allow self treatment. .

  Ultrasound therapy is often used to treat pain such as knee, hip, elbow, finger, knuckle, TMJ, back pain and radiating sciatica pain but if the caregive or therapist is not careful the choice of the head size may defeat the treatment.

   As previously discussed in our article on using ultrasound and also choosing which frequency it is equally important to choose the right head size for the ultrasound machine application.   Ultrasound will not flow through air and if the head of the applicator is too large for the area being treated then the ultrasound machine will repeatedly turn itself off as a safety mechanism to prevent harm to the patient.
