Haptic robot in fMRI environment represents efficient tool for noninvasive assessment of brain activities in various tasks performed by upper extremities. A prototype of original three degrees of freedom fMRI compatible haptic robot was developed together with control system and appertaining virtual environment. Also performed were all experiments with the upgraded commercial haptic robot.

Virtual mirror is represented by visualization of training person and virtual trainer in common virtual environment. It is aimed for training of lower extremities movements. Virtual mirror was used for comparison of haptic and visual representation in adaptation of healthy persons to virtual environment. Haptic feedback was realized by use of Locomat active exoskeleton under impedance control. Voice signals were introduced in both representations.

Rehabilitation system for upper extremities training is aimed for simultaneous exercising of finger flexors and extensors. The original approach combines tracking task in isometric conditions with functional electrical stimulation (FES). The patient follows the reference force either by only voluntary contraction of muscles or by the help of FES assistance. FES is closed loop controlled by a PI controller.

Quantitative assessment and objective evaluation of patient’s capabilities during rehabilitation process are important challenges of rehabilitation engineering. A human-centered approach was used in the design and development of a mechanical structure equipped with eight force/torque sensors that record quantitative data during the initiation of a predefined set of activities of daily living. The system is mainly aimed for assessment of patients after stroke, however it is interesting also for research in neuroscience.

Computer based device for evaluation of postural responses was developed as a supplement to clinically accepted BBS instrument used for subjects after stroke. The approach can be applied also in telerehabilitation. The emphasis is based on assessment of position of reaction force and the ratios of anterior-posterior and medial-lateral response before and after rehabilitative treatment.
