dc.description.abstracten	In this thesis, we propose and develop an approach to a myoelectric (EMG-driven) control of an upper limb orthosis. This orthosis is intended for patients, who are unable to flex their arm at the elbow joint at will (i.e., due to traumatic injuries of the brachial plexus), but can extend it. The flexion of the orthosis is thus controlled indirectly –– by rotating the patient’s head to the right (or just tensing the left ster- nocleidomastoid muscle). In contrast, during extension, orthosis reacts to signals from the arm (more precisely, from the triceps brachii muscle); this way, it does not resist the extension of the patient’s arm. In the scope of the thesis, we focus on the development and testing of an ap- proach to myoelectric control, including signal preparation, processing, and detect- ing target muscle activity in a noisy EMG signal from sensors placed on the Stern- ocleidomastoid muscle and Triceps brachii muscle and also designing experiments for data gathering and its analysis. The injuries of patients for whom this orthosis is developed are considered irre- versible and completely prevent forearm flexion and the restoration of that move- ment. Because of this, the orthosis is meant more for assistance than rehabilitation. The idea, concept, and mechanical part of the orthosis were developed over the course of a few years by a team of researchers, mechanical and hardware engi- neers, and surgeons. The team also oversaw the development of myoelectric con- trol, recorded experimental data, consulted on various issues, and assisted over the whole course of this thesis work.	uk
