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...
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...
Spasticity is often seen in patients with central nervous system lesion, such as stroke. It hinders functional movement and may induce pain. Current measures for assessing Spasticity are either quantitative but not convenient to use or convenient to use in clinics but lack of objective quantification. We developed a manual spasticity evaluator (MSE) to evaluate the spasticity quantitatively and potentially...

A back analysis system has been used to assess the occurrence of low back pain by evaluating the fatigue characteristics of back muscle during a sustained, constant-force trunk extension. A study was made to compare the median frequency values simultaneously obtained from six back muscles of patients (in remission, but having a history of chronic back pain) and normal control subjects. The median...
