Can someone list the disorders that might be possible with abnormal electromyography results?

Too many to list. Electromyography is performed for abnormal symptoms such as weakness due to conditions in either muscles or peripheral nerves. There are many such conditions. This web page (http://www.Nlm.Nih.Gov/medlineplus/ency/article/003929.Htm) has a list of many of these conditions, but you should always speak with your doctor about your specific results.
