In this review, the role of high-resolution ultrasound in the diagnosis of neuromuscular disease as a tool complementary to electrodiagnostic techniques will be discussed, including indications, advantages, limitations, and potential for future research. Ultrasound-guided needle placement can be used to increase accuracy and safety of nerve conduction studies and needle electromyography. Ultrasound imaging of nerve and muscle can provide additional diagnostic information when performed in conjunction with nerve conduction studies and needle electromyography in the setting of nerve entrapment, nerve inflammation, and muscle disease. Its unique features include the ability to image structures dynamically in real time and the technique of sonopalpation. Because neuromuscular ultrasound is a rapidly evolving diagnostic tool with significant changes in technology, which facilitates its increased use, there is a steadily growing body of literature in this area. However, there remains an ongoing need for high-quality studies that evaluate the role and cost-effectiveness of neuromuscular ultrasound, both when used alone and in combination with electrodiagnosis.
