Dr. Barrish conducts EMG studies to diagnose nerve and muscle disorders. These studies include several components. The nerve conduction portion involves stimulating specific nerves in the arms or legs and measuring the time it takes for impulses to travel. A slow, reduced, or absent response may indicate a pinched or diseased nerve. In certain cases, an electromyogram is performed, where a sterile, fine needle is inserted into a muscle to record electrical activity. Abnormal EMG patterns can signal nerve or muscle dysfunction, helping guide diagnosis and treatment.

why are emg studies conducted?

EMG studies are used to evaluate symptoms such as numbness, tingling, abnormal sensations, muscle weakness, and pain in the upper or lower extremities. They are commonly used to confirm conditions like carpal tunnel syndrome, which causes hand numbness. Additionally, EMG studies can assist in diagnosing nerve disorders such as peripheral neuropathy, as well as muscle disorders like polymyositis. They are also useful for patients experiencing neck or back issues to determine if nerve involvement is contributing to their symptoms.

how to prepare

Little needs to be done to prepare. You should bathe or shower before the study. Wash your arms and legs to remove any body oils. Do not use lotions, creams, or bath oils as these may interfere with the study. It is good to wear comfortable, loose clothes. For upper extremity tests, it is best to wear short sleeves or a tank top. For lower extremity tests, it is best to wear shorts. There are no restrictions in terms of meals and you do not need to stop taking any medications. You may be asked to contract certain muscles or position your body during the exam. There are no lasting effects from this study.
