Toward a wearable monitor of local muscle fatigue during electrical muscle stimulation using tissue Doppler imaging [PDF]

Wearable Technologies, 2022
Electrical muscle stimulation (EMS) is widely used in rehabilitation and athletic training to generate involuntary muscle contractions. However, EMS leads to rapid muscle fatigue, limiting the force a muscle can produce during prolonged use.

Doppler tissue imaging [PDF]

ACC Current Journal Review, 1996
Summary Doppler tissue imaging is a novel means of imaging that interrogates high amplitude, low velocity echoes in the range of tissue and myocardial motion. In addition to providing a qualitative aid in edge detection and wall motion analysis, quantitative interrogation of myocardial velocities may provide insights into normal and abnormal systolic

Tissue Doppler Imaging

Journal of the American College of Cardiology, 2007
In der vorliegenden Arbeit wurden Strain und Strain Rate zum ersten Mal in der Veterinärmedizin bei einer großen Population von Hunden eingesetzt. Beide Methoden sind, wie das TVI, Techniken des Gewebedopplers. Dieser basiert auf dem gleichen Prinzip wie der Blutflussdoppler.

Evaluation of Myocardial Injury using Standard Diagnostic Tools and Tissue Doppler Imaging in Blunt Trauma Chest [PDF]

Journal of Clinical and Diagnostic Research, 2017
Introduction: Myocardial contusion is an entity in chest trauma which is difficult to diagnose. Current practice relies more on cardiac-specific biochemical markers and standard echocardiography, but no gold standard test exists.
