Electromyography Fundamentals

Electromyography FundamentalsGregory S. Rash, EdDElectromyography (EMG) is the study of muscle function through analysis of the electrical signals emanatedduring muscular contractions. Electromyography is often abused and misused by many clinicians and researchers. Manytimes even experienced electromyographers fail to provide enough information and detail on the protocols, recordingequipment and procedures used to allow other researchers to consistently replicate their studies. Hopefully, this chapter willclarify some of these problems and give the reader a basis for being able to conduct Electromyography studies as part oftheir on-going is measuring the electrical signal associated with the activation of the muscle.

tension despite constant or even larger amplitude of the muscle activity. There is a loss of the high-frequency component of the signal as one fatigues, which can be seen by a decrease in the median frequency of the muscle signal. During move-ment, there tends to be a relationship with EMG and velocity of the movement.
