title: [Dynamic ultrasonography].
abstract: The ability to perform dynamic evaluation is a great advantage of ultrasound especially for musculoskeletal evaluation. Different manoeuvres are routinely used. The importance of the mobility of a structure or an articulation, but also the grade of compression of the lesion, can provide useful diagnostic information. For ligaments, the tension of each band is important and mobilisation is often able to depict some conflicts between the tendons and others structures. Muscle contraction is also an important element for making the diagnosis and, similar to a Valsalva manoeuvre for the diagnosis of a hernia. Interventional procedures are also facilitated by this dynamic evaluation. On the other hand, this great advantage requires the presence of a physician during the examination.
