1. A method for improved rehabilitation of ankle motion for the treatment of stroke by visually-driven priming of motor movement, the method comprising:
operating a sensor that is coupled to a foot or ankle by way of a strap or an expandable fabric garment to generate a first signal representative of ankle angle over a first period of time;
determining, based on the first signal, a range of angles detected over the first period of time;
prior to a second period of time, operating a display to provide an indication to prime a repetitive motor movement, wherein the indication represents at least one full cycle of the repetitive motor movement with respect to ankle angle as a function of time;
operating the sensor to generate a second signal representative of ankle angle over the second period of time;
during the second period of time, mapping the second signal to a user location with respect to ankle angle relative to the repetitive motor movement; and
during the second period of time, operating the display to update the indication that represents the repetitive motor movement, wherein operating the display to update the indication that represents the repetitive motor movement includes updating a location, relative to the representation of the repetitive motor movement, of a cursor according to the user location.
