"Endlosschleifen im Kopf"

Beitrag zum Thema Ohrwurm in SWR2 vom 10. Dezember 2017:

"Jeder kennt sie, kaum einer mag sie: Ohrwürmer. Schon länger beschäftigen sich Psychologen und Mediziner mit dem Phänomen. Inzwischen weiß man, wie sie in den Kopf hinein kommen und was man dagegen tun kann. Musikforscher aus Hannover versuchen nun auch zu erklären, was neuronal im Kopf vor sich geht, wenn eine Melodie in Schleife läuft. Leonie Seng fasst den aktuellen Stand der Forschung zusammen."

Hier zum Nachhören.

Musician's Dystonia is Highly Task Specific: No Strong Evidence for Everyday Fine Motor Deficits in Patients

Aurélie Hofmann, Michael Grossbach, Volker Baur, Joachim Hermsdörfer, and Eckart Altenmüller

Objectives:

1) To examine the fine motor skills used everyday by patients suffering from musician's dystonia (MD) in the upper limb in order to verify whether MD is task-specific; and 2) to compare the affected and non-affected hands of MD musicians vs healthy musicians in performance of these tasks in order to clarify whether dystonic symptoms can be found in the non-affected side of MD patients.MD is typically considered to be focal and task specific, but patients often report impairment in everyday life activities. Furthermore, in the course of MD, about 15\% of patients complain of dystonic symptoms in other parts of the body.

Methods:

Twenty-seven musicians affected by MD and 27 healthy musicians were studied using 1) the Motor Performance Test Series, 2) a kinematic analysis of handwriting, and 3) an assessment of the grip force regulation while lifting and moving a manipulandum.

Results:

Patients performed most fine motor tasks without any evidence of a deficit. Exclusively in the handwriting tasks (2), they exhibited fewer frequencies of the written trace and a prolonged overall writing time.

Conclusion:

MD is highly task specific and does not strongly affect other motor skills. The subtle deficits in handwriting may be explained as a consequence of a general psychological disposition rather than as compensatory mechanisms to avoid the appearance of dystonic symptoms. Furthermore, we did not find signs of multifocal motor deficits in the unaffected hands of MD patients.
