Proposed model for skeletal muscle: Estimation of fiber location using ultrasonic effect

Abstract

Electromyography (EMG) used to discover diseases of the muscles, spinal cord, and peripheral nerves is a diagnostic test, which records the electrical responses of skeletal muscles while at rest and during voluntary action and electrical stimulation. A novel method, ultrasound modulated EMG, is proposed in this study as a mode of determining the location of fiber producing action potential. Frequency dependent attenuation of ultrasound is observed in skeletal muscle. The attenuation at different ultrasonic frequencies, which modulate EMG signal, assists to locate the source.
