Yesterday I promised to find some papers about el-stimulation. A good friend of mine have translated the instruction for ELPHA 2000 - TENS, I have such one and it helps me, if you want further information - please e-mail. Every time, and often in the middle of the night, I have cramps or pain I use my "ELPHA", I have had it for 2 years. the price in Danish crowns is about 4000,00 = $ 500,00 (about) Sonia NEVER GIVE UP ---------------------------------------------------------- This machine - ELPHA 2000 - is constructed an manufactured in Denmark. The machine contains both a muscle and pain stimulator, and the size of it is like a shawer. What is TNS ?? TENS means Transcutan nerve stimulation which is treatment of pain and cramps without medicine and side effects. TNS is a method of treatmenst based on electric stimulation of the nerves for the purpose of easing pain or to have the pain brought to an end. The idea is that after having located the pain or cramps two eelectrodes aaare being placed so that when the electric power is passing from one to the other it necessarily has to pass the painful aarea. Through the stimulation obtained herby the signal of pain which normally is transmitted through the nerves to the central nerve system where it is registrated as pain, will be blocked. The blocking is made by a theory (GATE CONTROL, Melzak R., Wall PD) which in common is called the theory of gaate meaning that the end of the nerves where they pass into the central nerve system may open and close a gate. By stimulating with TNS at a low frequency (about 2 Hz) but so powerful that in the aarea of stimulation vigorous contractions of the muscles will arise, this effect will show after 30 minutes of stimulation. As previously mentioned the method is easy to use. It is cleanly and effective and after a short time of instruction the patients may treat themselves as needed which means the pain arises. ------------------------------------------------------------ from Sonia
