Surface EMG in neurorehabilitation and ergonomics: State of the art and future perspectives

Abstract

Electromyography is a valuable technique that can be used for several purposes, including the comprehension and assessment of the motor system as well as the diagnosis of some pathologies and rehabilitation. Given the drawbacks of traditional surface electromyography recordings with two electrodes, a new approach called high-density surface electromyography enables implementation of spatial information to the temporal information content of the electromyographic signal. The following review describes the rationale for the use of high-density recordings, the state of the art techniques, and technologies for its detection and conditioning. Some examples are showcased providing new insights on muscle physiology, ergonomics (for the assessment and prevention of musculoskeletal disorders), as well as training and rehabilitation treatments.
