“…Validity of comparisons with neurophysiological data (e.g., skin conductance, heart rate) is compromised. This is an important consideration as researchers are more frequently correlating the FMPS with physiological data as interest in perfectionism grows (Ioannou, Furuya, & Altenmüller, ; Wirtz, Ehlert, Kottwitz, La Marca, & Semmer, ). The present study enables researchers to analyse FMPS data using parametric statistics and to make valid comparisons with physiological data, as ordinal‐to‐interval conversion tables have been produced.…”

Objective: The Frost Multidimensional Perfectionism Scale (FMPS) is widely used to measure the construct of perfectionism. Previous studies evaluating the factor structure of the FMPS have reported inconsistent findings. The study objective was to examine the psychometric properties of proposed four, five, and six factor solutions of the FMPS using Rasch analysis. Method: Using the responses from a sample of New Zealand athletes and exercisers (n = 425) from a variety of sports, we subjected the dataset to Rasch analysis. The overall and individual item fit, unidimensionality, local independence, and person separation reliability were evaluated by treating factors of each model as subtests. Results: After disordered thresholds were uniformly rescored, the factor Organisation displayed significant misfit to the model across all three solutions tested. Removal of Organisation and combining two parental facets into one resulted in adequate model fit and good item discrimination ability for all three solutions. The modified six-factor model was the best in terms of reliability, with no differential item functioning and the highest person separation index. Conclusion: The present results support the psychometric properties and internal structural validity of the rescored FMPS with the parental factors combined and without the Organisation facet. Psychometric properties of the instrument can be further enhanced by using the ordinal-to-interval conversion table presented here, which does not require modification of the original response format. These findings will be of interest in different areas where accurate assessment of the overall perfectionism trait is important and open new avenues for perfectionism research.

“…Derzeit ist die Hypothese, dass bei einigen Patienten ängstlich gefärbter Erwartungsdruck, ungenügende "Coping-Mechanismen" bei erhöhtem Stress und möglicherweise ein erhöhter Sympathikotonus zu situativen Verkrampfungen führen, die sich dann unter ungünstigen Bedingungen, z. B. durch Überfokussierung oder traumatischer Verarbeitung im Bewegungsgedächtnis fixieren können (21). Generell scheinen diese "psychologisch" getriggerten dysfunktionalen Bewegungsgedächtnisse weniger stark fixiert zu sein und eher einer Therapie zugänglich zu sein als die durch sensomotorische Überlastung getriggerten Fehlbewegungen.…”

ZusammenfassungMusizieren auf professionellem Niveau ist eine der komplexesten menschlichen Leistungen. Extrem schnelle und komplexe, zeitlichräumlich präzis definierte Bewegungsmuster müssen mit hoher Zuverlässigkeit gelernt, gespeichert und abgerufen werden, um die Erwartungen der Zuhörer zu erfüllen. Um diese Fähigkeiten zu erwerben, müssen Musiker über viele Jahre hinweg intensiv üben. Steigende Arbeitsbelastung am Instrument kann zu maladaptiver Plastizität des Zentralnervensystems führen und motorische Störungen, wie z. B. die Musikerdystonie auslösen. Die Musikerdystonie ist durch den permanenten Verlust der Kontrolle hoch präziser Bewegungen beim Spielen eines Musikinstruments gekennzeichnet. Sie betrifft etwa 1–2% der Berufsmusiker. Pathophysiologisch liegen gestörte Inhibition und sensomotorische Integration, möglicherweise auf dem Boden einer genetischen Veranlagung vor. Als „dynamisches Stereotyp” wird eine zunächst vorübergehende Verschlechterung der Feinmotorik bezeichnet, die häufig durch psychologische Stressoren oder Müdigkeit ausgelöst wird und als Vorform der Dystonie betrachtet werden kann.Die Behandlung der motorischen Störungen bei Musikern umfassen ergonomische Anpassungen, Anticholinergika, Retraining, und lokale Injektionen mit Botulinumtoxin. Präventionsstrategien in der Ausbildung junger Berufsmusiker sollten auf ein gesundes Arbeitsverhalten, Selbstmanagement, und psychologisch unterstützenden Unterricht ausgerichtet sein.

“…In a recent study on MD, Ioannou and Altenmüller demonstrated that 56% of musicians with dystonia were suffering from psychological symptoms, such as increased trait anxiety and obsessive-compulsive behavior [ 20 ]. These premorbid psychological factors seem to play a role in triggering task-specific dystonia, since, on average, symptoms of dystonia occurred 10 years earlier in musicians with psychological issues as opposed to MD patients with no elevated levels of stress and anxiety [ 21 ]. Here, we wanted to address the question, whether anxiety, perfectionism and other psychological symptoms might also contribute to triggering WC.…”

Pathophysiology of writer’s cramp: an exploratory study on task-specificity and non-motor symptoms using an extended fine-motor testing battery

BackgroundWriter’s cramp (WC) is a task-specific focal dystonia which manifests itself as abnormal postures interfering with motor performance. As the spread of motor symptoms remains controversial and non-motor symptoms are widely discussed, in this exploratory study, we explore the pathophysiology of WC, focusing on task-specificity and the psychological profiles of WC patients.MethodsIn 14 right-handed WC patients and matched controls, we assessed motor control by applying motor performance tests (Vienna Test Series), as well as using writing analysis and grip-force measurements. Moreover, detailed psychological factors were assessed. Classification trees were used to distinguish patients from controls.ResultsThe total duration of writing and the vertical writing frequency of the pen are the most important variables to split the data set successfully into patients and controls. No other variables concerning motor performance tests, grip-force measurements or psychological factors correctly separated patients and controls.ConclusionsOnly variables from the writing tasks successfully separated patients and controls, indicating a strong task-specificity of WC in our patient group. Future research should be performed with larger samples of untreated WC patients in early stages of impairment, without any secondary motor disturbances, to verify our findings.
