Résumé

The type, distribution pattern and time course of spontaneous muscular activity are important for the diagnostics of neuromuscular diseases in the clinical practice. In neurogenic lesions with motor axonal involvement, pathologic spontaneous activity (PSA) is usually reliably detectable by needle electromyography (EMG) 2-4 weeks after occurrence of the lesion. The distribution pattern correlates with the lesion location. The focus of the present work is the description of the different forms of PSA in myogenic diseases. Art, Verteilungsmuster und der zeitliche Verlauf muskulärer Spontanaktivität sind für die Diagnostik neuromuskulärer Krankheiten im klinischen Alltag bedeutsam. Bei neurogenen Läsionen mit motorisch axonaler Beteiligung ist pathologische Spontanaktivität (PSA) meist 2 bis 4 Wochen nach Läsionsbeginn mittels Nadelelektromyographie sicher fassbar. Das Verteilungsmuster korreliert dabei mit dem Läsionsort. Schwerpunkt der vorliegenden Arbeit liegt in der Darstellung der unterschiedlichen PSA-Verteilungsmuster bei myogenen Erkrankungen.
