Electromyography (EMG) measures muscle response or electrical activity in response to a nerveâs stimulation of the muscle.The test is used to help detect neuromuscular abnormalities. During the test, one or more small needles (also called electrodes) are inserted through the skin into the muscle.n audio-amplifier is used so the activity can be heard.EMG measures the electrical activity of muscle during rest, slight contraction and forceful contraction. Muscle tissue does not normally produce electrical signals during rest.
Respiratory muscle weakness should be considered in patients whose dyspnea cannot be explained by pulmonary disease, cardiac disease, anemia, or deconditioning.First symptoms may occur when respiratory muscles are under increased load, such as when standing in deep water, swimming, or in the supine position.yspnea is common in advanced stages of neuromuscular disorders, but it is infrequently the presenting symptom. However, dyspnea is a frequent complaint in a primary care setting but is rarely caused by a respiratory muscle weakness.
What is a abdominal strain? A strain is an injury to a muscle. A strain can vary in severity from a mild stretch to a full rupture. In an abdominal muscle strain, any one of the four muscles can be injured causing extreme discomfort with any trunk movements as well as with coughing, laughing, deep breathing, or sneezing. What are the classifications of abdominal strain? A mild stretching of a muscle is diagnosed as a first degree abdominal strain and can result in localized pain, mild swelling, and pain with movement, coughing, laughing, deep breathing, or sneezing. A more severe injury of an abdominal muscle is a partial tear (second degree). Depending on the amount of fibers torn, this type of injury may be quite debilitating for the athlete. The athlete may experience sudden abdominal pain, marked tenderness, localized swelling, and discoloration.
