title: [Detection of fasciculations and other types of muscular hyperkinesias with ultrasound].
abstract: Muscular hyperkinesias can be visualized by means of ultrasound (US): Ultrasonographic detection of fasciculations has been best evaluated. However, so-called ripplings, myoclonias and choreatic hyperkinesias as well as tremores can also be visualized by US. Muscular US has proven as a precise imaging technique for the detection of fasciculations. Fasciculations are brief, localized muscle twitches, usually lasting for 0.2 - 0.5 seconds. Some myoklonias may present similar in US, others present with a longer duration. In addition, muscle US allows a very easy and reliable detection of tremor frequency. This article reviews the present ultrasonographic facilities in the detection of muscular hyperkinesias and gives future perspectives.
