Abstract: | Determining the acting shoulder and muscle forces in vivo is very complex. In this study, we developed a control strategy for a glenohumeral simulator for ex vivo experiments that can mimic physiological glenohumeral motion and overcome the problem of over-actuation. The system includes ten muscle portions actuated via cables to induce upper arm motion in three degrees of freedom, including scapula rotation. A real-time optimizer was implemented to handle the over-actuation of the glenohumeral joint while ensuring a minimum of muscle tension. The functionality of the real-time optimizer was also used to simulate different extents of rotator cuff tears. Joint reaction forces were consistent with in vivo measurements. These results demonstrate the feasibility and added value of implementing a real-time optimizer for using in vivo data to drive a shoulder simulator. Die Bestimmung der wirkenden Schultergelenks- und Muskelkräfte in vivo ist sehr komplex. In dieser Studie wurde eine Kontrollstrategie für einen glenohumeralen Simulator für ex vivo Experimente entwickelt, der die physiologischen glenohumeralen Bewegungen nachahmen und das Problem der Überaktuation lösen kann. Das System umfasst zehn Muskelsegmente, die über Motoren via Kabelzüge angesteuert werden, um die Oberarmbewegung in drei Freiheitsgraden, einschließlich der Skapularotation, zu induzieren. Ein Echtzeit-Optimierer wurde implementiert, um die Überaktuation des Glenohumeralgelenks zu lösen und gleichzeitig eine minimale Muskelvorspannung zu gewährleisten. Die Funktionalität des Echtzeit-Optimierers wurde auch genutzt, um verschiedene Grade von Rotatorenmanschettenrupturen zu simulieren. Die Gelenkreaktionskräfte stimmten mit den in vivo Messungen überein. Diese Ergebnisse zeigen die Machbarkeit und den Mehrwert der Implementierung eines Echtzeit-Optimierers für die Verwendung von in vivo Daten zur Steuerung eines Schultersimulators. |
