Abstract
Repetitive peripheral magnetic stimulation (RPMS) is an innovative approach in treatment of central paresis, e.g. after stroke, by inducing muscle contractions and relaxations. The therapeutic effect can be increased by a closed loop control to induce coordinated movements in the forearm and the fingers. An appropriate model of muscle contractions induced by RPMS provides the basis for the controler design. In the presented paper a model based on a Hammerstein-structure for the contraction of the biceps brachii will be established. This model also builds the basis for a nonlinear system identification which is used to individualize the model to a single subject.
