One of the great challenges for understanding muscular diseases is to assess noninvasively the active and passive mechanical properties of the musculoskeletal system. In this paper we report the use of ultrafast ultrasound imaging to explore with a submillimeter resolution the behavior of the contracting tissues invivo (biceps brachii). To image the contraction, which is a very brief phenomenon (<100...
The non invasive and in vivo assessment of the active and passive properties of the musculoskeletal system remains today a great challenge for the understanding of muscular diseases. In a previous paper, we showed that the transient contraction of a muscle fiber bundle triggered by electrostimulation can be followed in space and time by an ultrafast ultrasound system. On the one hand, this experiment...
Although numerous techniques are commonly used to study muscular or neuromuscular diseases, in vivo muscle contraction remains a difficult event to image in real time. On one hand, time accurate techniques such as for example, mechanomyography, electromyography, or acceleromyography; allow only the assessment of global parameters of musculo-tendinous complex. These estimated parameters are classically...
Electromyography (EMG) has been widely used for the functional assessment of muscles. On the other hand, sonography has been commonly used to detect the morphological information of human muscles in both static and dynamic conditions. In this study, we demonstrated the feasibility to use the continuous signals about the architectural changes of muscles detected in real-time from ultrasound images...
