Accupuncture & TENS units, an alternative to pills

Effective pain relief using a tens or an interferential device only happens when the electrodes are placed to inundate the actual painful area with a pleasant, tingling, rubbing type stimulus. The actual stimulus is making nerve firings of NON PAIN FIBERS, physical fibers, which makes those sensory nerves overcome the PAIN NERVES ( C-FIBERS), which are transmitting the pain stimulation. There is no magic, it’s simply a process of being aware of what is the purpose of putting the tens electrodes, usually self adhering multiple-use electrodes, in the proper location.

Unlike acupuncture in which the needle is very little, a tens or even interferential electrode has a much larger stimulation area and specificity of placement is not as critical. Needles in acupuncture often usually are meant to interrupt an electrical energy pain path, while electrical stimulation will probably be offensive and attack the area thusly interrupting and altering the electrical energy. The surface of an electrode might be 2 inch x 2 inch or even 4 square inches of surface area for each electrode equaling a total of 8 sq. inches, where the acupuncture needles surface is that of the hook itself times the depth the needle is inserted.

Acupuncture is a process of discovering and insertion in to an area a hook(s) whereas electrical stimulation (e-stim) is a process of hovering over as well as transmitting electrical energy in an area. Interferential has a much greater frequency ( rate-how many times machine goes off as well as on per second). The higher the rate, the less the resistance is, and the greater the penetration of the electrical stimulus. Traditional chinese medicine needles have to be placed past the point of the majority of resistance ( skin or scar tissue ) to get into the region of electrical energy to destroy the flow.

The dispersion of the energy with estim and reusable electrodes covers a much larger area and boosts the chances of pain stimulus interruption.

Electrode placement is actually solely about passing electricity between 2 or four electrodes through the painful area. As the pain moves, which is very common for persistent pain conditions such as osteoarthritis, fibromyalgia, RSD, back pain, radiating sciatica, foot pain, knee pain, joint pain, shoulder pain, RLS -Restless Lower-leg Syndrome, etc., then your electrodes can be repositioned to pass the stimulus through the pain area(s).

Electrodes are available in many varied sizes and shapes, from butterfly to oval to rectangular to circular and many more. How big the electrode chosen is done to cover the area receiving treatment. If the pain emanates within the spine and the unpleasant area is Six inches or so long then often a 1″ by 6″ electrode will be used, or perhaps an Oval electrode, and staggered positioning, so the 6 in . per electrode of excitement surface area (SSA) can be placed to totally stimulate the painful spine area. When the patient has leg pain then a smaller 2″ Round electrode may be used to include the popliteal space at the rear of the knee, that is much smaller, but the excitement will cover the knee pain area.

Usually the two electrodes per channel can be of differing shape and size depending on the severity of the pain in a particular area. This process allows the electrical stimulus to be targeted by intensity, especially when utilizing interferential therapy. Interferential therapy requires larger electrodes due to what is called “current density”.

Current density is comparable to one standing in a shower that delivers 10 gallons per minute of water through only one small hole. When the patient is position a few feet away under that polished brass shower head then the single flow of water would be unpleasant due to the pressure at the rear of the flow. Showering would be a painful procedure. That is overcome, through rather than one small hole add One hundred more to the polished brass shower head, and now the sensation of showering is comfortable and possible without pain. Along with interferential the same principles apply to electrodes. Electrodes larger than typical tens electrodes are used to reduce the current density by increasing the stimulation surface area.

With interferential therapy, due to the 8,000+ rate, electrodes used are generally larger than a typical tens electrode of 2″ x 2″. Since there is considerable more energy then the dispersement area has to be greater than 4 sq. inches. Interferential therapy also prolongs the life associated with electrodes because, unlike tens therapy, the brief 20 - 45 minute interferential treatments produce carryover pain relief, and do not need an electrode to be worn continuously. Fewer electrodes are essential for interferential therefore additionally less cost.
