Kernrechtsfrage
Whether the event of 21 April 2007 was an accident under Art. 4 ATSG, especially whether the external factor was unusual.
Extrahierter Entscheid
Yes. The disease-related loss of motor control caused a programmatically abnormal movement; the unusual external factor cannot be denied by comparing her conduct to that of a healthy person.
Extrahierte Begründung
The assessment of unusualness is objective. A disorder that makes a movement uncoordinated and brings the limb out of control can constitute a programmatic deviation and thus an unusual external factor. Denying this because the insured had frequent motor failures would improperly discriminate against disabled insured persons.
