A method to assess and train the sensorimotor function of a human subject comprising a) generating in a computer a pattern comprising a path, b) placing a motion sensor in the head or a member of said subject, which sensor is connected to said computer such that said computer can track the movements of said sensor and producing a cursor tracking on a display, c) drawing said path in said display a target cursor after the subject has been instructed that follow the target cursor moving the cursor tracking, in which the sharpness of bends in the path and speed of the target cursor are related as defined by the power law 2/3, d) measuring the correlation and / or deviation of said cursor relative to said tracking target cursor, wherein measuring comprises determining the correlation amplitude accuracy and precision directional, e) providing a v aluation of sensorimotor function of said subject, based on the correlation and / or deviation measured in step d), wherein the method is characterized in that said generated pattern pre-classified in a class among a plurality of kinds of difficulty patterns incremental difficulty, those classes of difficulty defined by parameters including (a) number of curves in the path pattern, (b) sharp curves in the path pattern, (c) speed target cursor parts curves path pattern and straight portions of the path pattern, and (d) the relationship between the curved portions facing straight in the pattern.Un procedimiento para valorar y para entrenar la función sensitivomotriz de un sujeto humano, que comprende a) generar en un ordenador un patrón que comprende una trayectoria, b) colocar un sensor de movimiento en la cabeza o un miembro de dicho sujeto, sensor que está conectado a dicho ordenador de modo que dicho ordenador pueda rastrear los movimientos de dicho sensor, y producir un cursor de rastreo en un visualizador, c) dibujar dicha trayectoria en dicho visualizador con un cursor de diana después de que al sujeto se le ha ordenado que
