In this study, integrated circuits and micro-checks from known electronic muscle stimulation device consisting programmable designed. The method used in this study is a method of TENS. This method is a method of transdermal muscle and nerve stimulation. In this method, the nerves and muscles, electrodes through the skin, stimulated by electrical currents using different frequency and intensity of. The aim is to prevent the transmission of pain modulation excitation nerve connections.
To make the motor points of the muscles in the waves of muscle contraction to apply to. TENS called endorphins, a natural analgesic and sedative effects when used method consists of secreted. This method is physiotherapy; muscle contractions, ensure that coming loose, relieve pain, Is one of the alternative methods used to provide sedative effect.
Frequency of the circuit is designed with micro controllers, Set the output current to determine the duration and the intensity of the current is possible to determine for every patient. The type and nature of the wave are presented on the LCD screen as the user information.
Pain first modulation and TENS metotları explained. Then the intended block diagram, The working principle of the circuit diagram and the circuit will be explained. In the last part with some of the results and recommendations are described in the operation and future developments that may.
Symbols and Abbreviations: Some of the icons and abbreviations used in this study, are presented below, along with descriptions of.
History of electrotherapy
Elektroterapi, for diagnosis and treatment is the use of electrical agents. The use of electricity as a means of treating dates back to the ancient Greek and Egyptian;
Greek scholar and electric fish vibrations of Aetius glove used in the treatment of gout. Magnetized medicine scholar living in the Middle Ages, Paracelsus (magnet) bodies believed to be good for all treatments. However, this speeds Queen Elizabeth’ in doktoru Dr.. William Gilbert’ in 1600 published in “The Magnette” His book has aroused considerable interest.
1780 Galvani, Professor in the University of Bologna, frog’s leg muscle, the effect of electricity (gastroknemius) kasıldığını seen and as a result, electricity, only said that the animal’s tissues. After that, the Italian scientist Alessandro Volta nature, not only for electricity and animal tissues 1800 Volta invented the battery in. Galvani and Volta thus formed the basis for electrotherapy. The first book of 1745 by the German Fiziatrisi electrotherapy Kratzenstein′Published in.
Paris’ has recommended the use of electricity for muscle contraction Jallabert with kıvılcımlanmasının. Marat, habit, hemiplegia, and has authored several books for the use of electricity in the treatment of rheumatic diseases. Hemifumarate how certain period of drug treatment must be filed, electricity can also be given a certain time Volt required.
The first physiotherapy department 1840 Dr. in. London by Golding’ daki ‘Guy’ hospital Volt opened as electrotherapy department. After the discovery by Faraday induction coil Electrophysiology, faradic and galvanic stimulation of muscles and nerves of current laws 19. Du-century French BoisRaymond, Developed by Duchenne and Erb. American (Michigan) John H. Sinusoidal currents used by Kellogg muscle stimulation.
By Tesla in 1892 after the discovery of high-frequency currents′used in the treatment by the D’Arsonval. Diathermy 20. In the tenth century, first discovered by the German Zeynek and Nagelschnidt New York for medical purposes, and F. The Power, for surgical purposes Philadelphialı developed by Clark.
Short-wave diathermy American Schereschewsky, Witney and Volt discovered by the German Schliepake. Small wave diathermy (micro dalga diathermy), modeled radar used in time of war by the British scientist Sir Arthur Tisdale “Microwave” With the development of the tube were called.
The main purpose of this study through the skin electrical muscle nerve stimulator unit to realize the design and implementation of. First, however, the perception of pain, The material used for the excitation methods and methods that can be used DÜEKSU units introduced is intended to provide background information on the topic.
Nowadays, hard and long-term pain in practice for a long term in a state analgesic, alternative method is used because of the risk of damage to the kidney or liver, skin-mounted electric nerve stimulation, physical therapy as it is known that TENS Unit use. The method of electric current, the electrodes to stimulate the nerves under the skin, through the skin with the help of the method of transmission. This technique then “Transkutaneous Electrical Nerve Stimulation” referred to as TENS which stands for.
Skin over the muscles used in electrical nerve stimulation (DÜEKSU) with a very good success rate of the method regularly used in the reduction or elimination of pain. Today, in the form of an electric current is used quite widely TENS.
Matches on direct current produces a short-term TENS The skin over the muscle electrical nerve stimulation devices for the first 1919 has been used in. The first time through electrodes placed on the skin, Wall and Sweet peripheral electrical stimulation of peripheral nerves that temporarily improved as a result of chronic pain reported.
Before either of these types of electrical currents, efforts were made to reduce the pain, and those who follow a very different shapes used in electrical. They are very similar to the observed effect, but over time many of them have been abandoned at, sinusoidal current, and it is only on the changes made have been obtained from the diadynamic currents continue to be used for pain control.
TENS stimulation through the skin, peripheral nerves can be explained as. Used for the purpose of treatment is to eliminate or alleviate the aches and pains. This alerts the brain secretes endorphins, natural pain when we do not have to play as pain reduction or elimination of agents will perform.
In the external environment of the brain and body electrical stimulated capable of understanding and interpreting. TENS devices produced by some of the current forms and information on central nervous system, especially when large changes in pain sensitivity may focuses on.
TENS electrodes placed on the skin over the nerve system controlled by applying a low-voltage electrical current is carried. TENS’ has increased in importance in the development of pain treatment with electric current through. Originally TENS, as a method of pain control directly to stimulate the nerves of the dorsal column stimulator is made as a byproduct of electricity developed dorsal column.
This stimulator surgically inserted into the body. TENS is developed as a non-invasive technique is adequate in most patients in reducing pain without the need for surgical intervention, such as dorsal column stimulator is.
1965′of pain by Melzack and Wall “Gate Control Theory” Following the identification of electrical currents through the reduction of pain research with great interest, and his treatment of TENS heard and seen large increases in the use of.
TENS’ There are so many applications that are currently in.. Is safe and effective in treating pain, and “The Food and Drug Administration” (FDA) After receiving the approval of TENS and various diseases caused by the surgical procedure used for acute and chronic pain. According to FDA regulation of medical device use TENS II. between-class devices.
So the distribution and implementation of the patient must be made by a licensed physician. U.S.’ national standards for transcutaneous electrical nerve stimulators were also(1985). Accordingly, the primary indication for TENS is defined as follows:”Symptomatic control of the management and treatment of chronic pain, or as adjunctive therapy and post-operatively as well as post-traumatic and acute pain is used to treat.
In many countries today are produced in our country and TENS devices for the treatment of clinical and home. TENS devices produce the correct stream of positive asymmetric biphasic square waves and negative spinous, Matches on monophasic and biphasic square-shaped square still widely used. They are most common in symmetric or asymmetric balanced, biphasic square wave. More asymmetric square wave output electrodes are used to give the polarity.
