Solution:

Definition of EMG:

Electromyography (EMG) is an experimental technique concerned with the development, recording and analysis of myoelectric signals.

Myoelectric signals are formed by physiological variations in the state of muscle fiber membranes."

Unlike the classical Neurological EMG, where an artificial muscle response due to external electrical stimulation is analyzed in static conditions, the focus of Kinesiological EMG can be described as the study of the neuromuscular activation of muscles within postural tasks, functional movements, work conditions and treatment/training regimes.

Typical benefits of EMG:

Typical benefits are:

• EMG allows to directly “look” into the muscle

• It allows measurement of muscular performance

• Helps in decision making both before/after surgery

• Documents treatment and training regimes

• Helps patients to “find” and train their muscles

• Allows analysis to improve sports activities

• Detects muscle response in ergonomic studies.
