Electromyography In Ergonomics [Hardcover]

Electromyography (EMG) is the study of muscle behaviour via electronic means, and is thus a technique fundamental to ergonomics, physiology and biomechanics. This text describes the principles of EMG and its application domains, focusing on anatomy, biology, muscle characteristics, physics, mechanics, EMG signal, noise/artifacts/errors, equipment/devices/techniques, interpretation and computerised data acquisition, and analysis. The book provides a theoretical base, a strategic framework and user experiences.Electromyography in ergonomics; physiological basis and concepts of electromyography; noise and artefacts; EMG interpretation; muscle energetics and electromyography; EMG alterations at sustained contractions with special emphasis on application in ergonomics; electromyography of upper extremity muscles and ergonomic applications; EMG of neck and shoulder muscles - the relationship between muscle activity and muscle pain in occupational settings; surface electromyography assessment of lower back pain; application of EMG in ergonomics - a clinical perspective.
