Electric Electric Planning - Investigation and Results -Analysis

Nerve -electrical conduction test: In this test, kinetic and sensory nerve fibers are examined, especially in the extreme ends of the hands. The skin over the tested nerve receives electric motivation through some electrodes. Through another electrodes, a motor examination is done above the muscle that receives orders from the stimulating nerve. The stimulus strength is gradually increased until we reach the maximum reaction that is not changed to. In this way, we ensure that all nerve fibers are activated and make sure they are connected to the catalyst. The period from the moment of motivation is called the reaction to the muscle or the corresponding nerve, the ‘distal latency’. Closest to the appearance of a longer “cumin” reaction, called “minimal cumin”. The difference between the maximum cumin and the minimum cumin indicates the time needed for the nerve to deliver the signal between the two stimulating points (stimulation). The distance between the two points and the velocity of the electrical delivery of the kinetic nerves is calculated based on the following equation: (the receipt speed = the difference between the two cumin / distance). Through this method, the nerve fibers that are only covered in miles are examined, in which the velocity of the receipt is large. The microscopic nerve fibers are covered with miles or not covered with it, very slowly and are not measured in this way. (EMG) Test: This test is done by entering electrodes into the muscle to inherently record the electrical capabilities to the muscle fibers. In most cases, a concentrated needle (mono center) is inserted so that the center of its environment is isolated, while the capabilities measured between the middle and the ocean. The electrical activity of the muscles is documented on the EMG screen, and it can also be heard by the sound enlargement. The integration of what the eye sees and what the ear hears is important and an assistant for those who take the test to determine the quality of the electrical activity of the muscle. The decay of the electrical properties of the muscle fibers, in the professional language, is called ‘shots’. The electrical activity of the muscle is measured in three cases: during the rest, when the muscle is slightly activated, and when the muscle is tense. In healthy muscles, there are no electrical activities during the rest time. But after some disorders occur in the performance of the nervous muscle, the fibers themselves -“shots” make up to the time of rest. These relevant and subjective fiber bullets are called ‘fibrility’, or the sharp positive abilities. If the source of these shots is the motor units (kinetic units contain nerve cells in the spinal cord, the dialogue – nervous leil – and its branches, and the muscle fibers controlled by them), it is called ‘packages’ (belt screens). If the muscle is slightly activated, it appears on the screen a limited number of kinetic units. In the development of neurons or nerves, the size of the kinetic units increases and on the screen it appears that their scope and extension is large. But as a muscle disease, these kinetic units become smaller. As a muscle tension, how to recruit kinetic units, is investigated. If the muscle is intact when tense, the kinetic units must increase to build us and prevent the baseline. However, since the number of kinetic units decreases when neurological diseases, its density is less. These kinetic units cannot even accumulate at the peak of “recruitment”, although the shelves of the shelves rise in an attempt to compensate their small number. On the other hand, when muscle disease has not reduced the number of kinetic units – they are already small. Therefore, the recruitment begins early, and a complete extension is observed in some of these units, even during a little effort. Through an EMG test, we can distinguish between primary diseases in the muscles and diseases that occur secondary to the damage of the nerves controlled by these muscles. But we cannot get to know the type of muscle disease through this test, so we must perform additional tests. Repeated nervous stimulation: This test is done to evaluate diseases associated with communication between nerves and muscles, such as Myasthenia Gravis. The method of performing this exam is similar to how to check the electrical compound. But instead of individual stimulus, nerves are stimulated several times. If the situation is normal, there is no change in the extent of the reaction received from the muscle. But when diseases associated with muscle-nerves communication, a 2-3 incentive is stimulated, so that a gradual decrease in the reaction recorded is noticed. Another investigation into the performance of the muscle muscle communication is an EMG examination of single muscle fiber. This test is performed by a special electric electrode that documents the electrical capabilities in some muscle fibers, not in the kinetic units as done in the normal (EMG) test. This test is very sensitive to signal disorders over the muscles. This investigation can detect all the muscles suffering from a certain weakness due to the communication disorder between the nerve and the muscle.
