How are EMG and NCS Used in Diagnosing Congenital Myopathies?
EMG and NCS are critical for diagnosing congenital myopathies. EMG can reveal abnormal muscle electrical activity, indicating a myopathic process. NCS can help differentiate between disorders affecting the muscles and those affecting the peripheral nerves. These tests are essential for identifying conditions such as spinal muscular atrophy (SMA) and congenital muscular dystrophy.
