Problems in a muscle, the nerves controlling a muscle, the spinal cord or the brain can all cause these kinds of symptoms.Įlectromyograms are useful in determining whether there has been pressure on a nerve or nerve root degeneration. Find out the cause of weakness, paralysis, involuntary muscle twitching or other symptoms.These disorders include a herniated disc, amyotrophic lateral sclerosis (ALS) or myasthenia gravis. Diagnose diseases that damage muscle tissue, nerves or the points where nerve and muscle join.Nerve conduction studies measure how well individual nerves transmit electrical signals to the muscles. Electromyography is usually done with nerve conduction studies. doi:10.Electromyography measures the electrical impulses of the muscles at rest and when contracted.
