Zusammenfassung

Dargestellt wird der Fall einer konservativ versorgten Patientin mit einer unilateralen Gonarthrose rechts. Mittels Oberflächen-EMG wurden Bein- und Hüftmuskeln beim Gehen untersucht. Der benötigte myo-elektrische Aufwand für einen zurückgelegten Kilometer wurde berechnet und mit Referenzwerten Gesunder verglichen. Die Analyse ergab für die Patientin veränderte Kennwerte sowohl des absoluten Aufwandes als auch der geschwindigkeitsabhängigen muskulären Aufwandcharakteristik. Mit der verwendeten Methodik können Muskeln hinsichtlich ihres funktionsspezifischen Aufwandes klassifiziert werden.

Abstract

A conservatively treated case with an unilateral osteoarthritis of the right knee joint is presented. Leg, thigh and hip muscles were studied during walking by means of surface EMG. The myo-electric effort required to travel a distance of one kilometer (cost-of-transport) was calculated and compared with healthy controls. For the patient the analysis revealed changes in parameters of both the absolute as well as the speed-dependent characteristic of muscular cost-of-transport. With the methodology used muscles can be classified in terms of their function-specific efforts (economy).
