Veränderung der Muskelkraft bei Patientinnen mit Anorexia nervosa während der stationären Behandlung - eine Pilotstudie

Published Online:September 01, 2006https://doi.org/10.1024/1422-4917.31.4.277

Abstract

Zusammenfassung:Fragestellung: Die Veränderung der Muskelkraft bei Patientinnen mit Anorexia nervosa während der stationären Behandlung sollte durch exakte Messung bestimmt werden. Methode: Unter Verwendung einer etablierten Messvorrichtung inkl. des Softwareprogramms «Quantitative Muscle Assessment» wurden in den Wochen 1, 2, 3, 4, 6, 8 und 10 des stationären Aufenthaltes die Maximalkräfte in vier verschiedenen Übungen für jede Körperseite bei zehn Patientinnen bestimmt. Alle wiesen vor der stationären Aufnahme einen vergleichbaren Krankheitsverlauf mit reiner Nahrungsrestriktion ohne überdurchschnittliche sportliche Betätigung auf. Ergebnisse: Es ergaben sich Hinweise auf einen interindividuell zu beobachtenden mehrphasigen Verlauf der Kraftrestitution. Die aufgrund der einfachen Durchführung andernorts häufig angewandte Übung Handgrip zeigte im Gegensatz zu den anderen untersuchten Muskelgruppen keine einheitliche Entwicklung. Seitendifferenzen waren nicht zu beobachten. Schlussfolgerungen: Patientinnen mit Anorexia nervosa zeigen eine objektivierbare, interindividuell vergleichbare, mehrphasige Zunahme der Maximalkraft der untersuchten Muskelgruppen während der Gewichtsrestitution.


Changes in muscular strength during treatment of inpatients with anorexia nervosa - a pilot study

Summary:Objective: Changes in muscular strength during treatment of inpatients suffering from anorexia nervosa were to be documented by exact measurement. Methods: The maximum strength of each side of the body was measured in 10 patients in the 1st, 2nd, 3rd, 4th, 6th, 8th and 10th weeks of inpatient treatment by means of a series of four different exercises. A well-established measurement technique, including the computer program «Quantitative Muscle Assessment», was used. All patients showed comparable symptoms of an anorexia nervosa, restricting type before admission (pure food restriction without over-exercising). Results: A polyphase course of the restitution of muscular strength could be seen in all patients. Since it is easily applied, the exercise «handigrip» has been used frequently elsewhere. In our study it failed to show a consistent development, in contrast to other muscle groups studied. Differences between the left and right sides could not be observed. Conclusions: Patients with anorexia nervosa showed an objectively comparable inter-individual polyphase increase in the maximum strength of the muscles under investigation during weight restitution.
