[Entrapment neuropathies - quality requirements for neurological and neurophysiological diagnosis].

In some entrapment neuropathies, the diagnosis is easily established on clinical grounds. The best example is the carpal tunnel syndrome, the most frequently diagnosed entrapment neuropathy. Other entrapment neuropathies are not clear-cut: There is doubt that the syndrome exists at all or its limits are poorly defined, or the frequency is rather variable from one medical center to another. In this situation, a clarification of the diagnostic criteria may be necessary, especially with regard to the most common and the most disputed nerve entrapments.
