Acupuncture Principles & Proper Electrode Placement On Tens & Interferential Pain Machines

Effective pain relief using tens or Interferential units occurs only when the electrodes are placed on the painful area irrigated with a pleasant, tingling, kind of massaging poticaja.Poticaj causes nerve firings of NO PAIN fibers, sensory fibers, which are sensory nerves to overcome the pain nerves (C fibers) that transmit the pain impulse. There is no magic, it is simply a process of understanding what is the purpose of putting tens electrodes, generally holding its own reusable electrodes, to the right place.

Unlike acupuncture, where the needle is very small, a few dozen or Interferential electrode has a much larger area of stimulation and the specific area is not so critical. Needles in acupuncture are often designed to stop the power path of pain and electrical stimulation is intended to be offensive and invade the area thusly breaking and shifting of electrical energije.Površina electrodes can be 2 cm x 2 cm or 4 square inches of surface electrode height total of eight square inches, which is the area of acupuncture needles to the needle itself times the depth of the needle is inserted.

Acupuncture is the process of finding and involvement in the needles (a) and electrical stimulation (E-Stim) is the process of floating above the power transmission in space. Interference has a much higher frequency (rate-how many times the machine goes off and the second). The higher rate, the less resistance, and the greater penetration of electrical stimuli. Acupuncture needles must be inserted past the highest point of resistance (the skin or scar tissue) in order to interrupt the electricity flow.

dispersion energy with frequent and repeated use of electrodes covers much larger area and increases the chances of the pain stimulus interrupts.

electrode placement is solely on the current passing between two or four electrodes through the painful area. As pain moves, which is very common for chronic pain conditions such as osteoarthritis, fibromyalgia, RSD, back pain, sciatica, radiating, foot pain, knee pain, joint pain, shoulder pain, RLS-Restless Leg Syndrome, etc. . and then the electrodes can be moved to go through the pain stimulus area (s ).

The electrodes come in many different shapes and sizes, from butterflies to oval to square the circle, and much more. The size of the electrode chosen was done to cover the area being treated. If back pain comes and the painful area is 6 inches or so long it often 1 "x 6" electrodes will be used, or Oval electrodes and partitioned space, so that is 6 inches by electrode stimulation area (SSA) can be placed on fully stimulate the painful area of ​​the spine. If the patient has pain in his knee and then a smaller 2 "round electrodes can be used to cover the popliteal space behind the knee, which is much less, but the stimulation will cover the area of ​​knee pain.

Often two electrodes per channel can be of various shapes and sizes, depending on the severity of pain in a particular area. This process allows the electrical stimulus to the target intensity, especially when using Interferential therapy. Interferential therapy requires large electrodes because of what is called "current density ".

the current density can be compared with one standing in the shower, which gives 10 liters per minute of water through a single small hole. If the patient is standing a few feet under the shower head, then a stream of water can be uncomfortable due to pressure behind the flow. Showers will be a painful process. This is overcome, but one small opening to add 100 more shower heads, a shower is now feeling comfortable and pain-free as possible. With Interferential same principles are applied to the electrodes. Electrodes larger than the typical tens of electrodes is used to reduce the current density by increasing the surface area of ​​stimulation.

S Interferential therapy, considering the 8000 + feet, the electrodes used are generally larger than the typical tens of electrodes 2 "x 2". Since then much more energy dispersement area must be larger than 4 cm square. Interferential therapy also prolongs the life of the electrodes, because, unlike the tens of therapy, a brief 20-45 minutes Interferential treatments produce carryover pain relief, and does not require electrodes to be worn constantly. Fewer electrodes are needed for Interferential time and less cost.
