AAEM minimonograph #45: the early development of electromyography

The use of electricity for therapeutic purposes began in the first century and became more refined as the properties of electricity became more understood. The works of Franklin, Galvani, Volta, and others contributed to this body of knowledge. Development of the string galvanometer, the advent of the vacuum tube, the introduction of concentric needle electrodes, and the development of the cathode-ray oscilloscope occurred during the first half of the 20th century. The science of electromyography and electrodiagnosis grew in its sophistication, leading to the formation of the American Association of Electromyography and Electrodiagnosis (now the American Association of Electrodiagnostic Medicine) with James Golseth, MD, as its first president in 1953.
