1. A method for assessing sensorimotor function of a human subject which comprises a) generating in a computer a pattern which comprises a trajectory path, b) placing a movement sensor on the head or limb of said subject, which sensor is connected to said computer such that said computer can trace movements of said sensor, and output a tracing cursor on a display, c) drawing said trajectory path on said display with a target cursor after the subject has been instructed to follow the target cursor by moving the tracing cursor, d) measuring the correlation and/or deviation of said tracing cursor from said target cursor, e) providing an assessment of sensorimotor function of said subject, based on the measured correlation and/or deviation in step d), wherein the method is characterised by in that said generated pattern is pre-classified in a class from a plurality of difficulty classes of patterns of incremental difficulty.
