Neurorehabilitation using the virtual reality based Rehabilitation Gaming System: methodology, design, psychometrics, usability and validation.

Background: Stroke is a frequent cause of adult disability that can lead to enduring impairments. However, given the life-long plasticity of the brain one could assume that recovery could be facilitated by the harnessing of mechanisms underlying neuronal reorganization. Currently it is not clear how this reorganization can be mobilized.

[Aneurysm of the popliteal artery following arthroscopic meniscectomy].

As a result of a case report, a bibliographic review was made about false aneurysms on the popliteal arteries accidentally produced following a meniscectomy by arthroscopy. Such type of aneurysms can be defined by its false wall, its sack-shape and extensive haematoma and its clinical presentation as an acute ischemia of an extremity. It should be noted that, in all cases, an important delete in the diagnosis time was registered.
