<p>The present invention concerns a switchable joint constraint system comprising at least one motion sensor, a joint constraint which is switchable between a mobile and an immobile state, a signal processing unit and a database. Motion sensor signals are compared to predefined situations. The joint constraint is switched according to whether predefined situations are met. The present invention furthermore concerns a process for handling sensor signals in such a system. The system may be used to support a constraint induced therapy (CIT) for the treatment of e. g. hemiplegy.</p>
