The invention relates to a physiological parameter measurement and feedback system, for measuring electrical activity of the brain (EEG) and position / motion of a body part, e.g. motion of an arm. Avirtual representation of either the moving body part or the intended movement as determined from the brain activity is presented as feedback to the subject on a display which can be implemented as ahead-up display. A clock module is operable to time stamp information transferred from a brain electrical activity sensing system and a position / motion detection system for joint processing. This non-invasive EEG-based brain-computer-interface is particularly useful for stroke rehabilitation.
