This thesis presents the creation of new multimodal methods of interaction and control of virtual therapies in the eld of robotic applied to neuro-rehabilitation for recovery the funcionality of the upperlimb of patients with Acquired Brain Injury. The outcomes achieved during the development of this Thesis are collected in three publications included in the Journal Citation Reports(JCR). A system of virtual therapies generation, with any type of environments based in daily life activities or therapeutic games, is presented in the rst part of the thesis. The aim of this system is to create a large variety virtual therapies in a quickly, economic and simple way. In addition, the proposed system improves the patient's motivation and adherence to the treatment. Thus, the frustation feeling is avoided through the adaptation of the di - culty level depending on patient's emotional state. One of the main features of this system is the interaction capacity of the generated tasks with various robotic devices based on an end-e ector con guration to control the avatar inside the virtual environments. In the second part of the thesis, a multimodal interface for neuro-rehabilitation therapies assisted by robotic devices is developed. This interface integrates the estimation of patient's psychophysiological state in the control loop. Through this system, user's physiological signals such as pulse, respiration rate, skin temperature and galvanic skin response are analysed to adapt automatically the feedback provided by the virtual environments. Then, the di culty level of the tasks generated by the motor task can be modi ed. The classi cation of physiological states are carried out by a new mathematical algorithm based in neural networks and the set fuzzy theory. Finally, a study about how the sensorimotor performance of the upper limb in patients with Acquired Brain Injury is in uenced by the virtual environments visualization in two or three dimensions. This study is perfor-med during neuro-rehabilitation therapies assisted by robotic devices. This robotic device is in charge of recording the kinematic movements to complete a statistical analysis. The presentation of two virtual tasks with the same nality, but with di erent graphic visualization on a screen while the patient manages the end-e ector of the robotic device to achieve the therapy targets, is the methodology of this study.
