| Popis: | Electromyography (EMG) is complementary to biopsy for a number of reasons. Firstly, it can be used to examine several muscles and nerves in any individual patient. Secondly it can be used sequentially during the natural history and treatment of neuromuscular disorders, and thirdly it is a useful parameter for choosing a suitable muscle for biopsy or, indeed, in deciding whether biopsy should be undertaken. If the EMG is normal, muscle biopsy is unlikely to reveal abnormalities, although there are exceptions to this, as in some metabolic myopathies. The EMG may also provide information about neuromuscular transmission and early reinnervation: functional concepts which are beyond the scope of ordinary histological investigation. |
