1. A tremor-reduction system comprising:a stimulation device configured to deliver electric current to a body region;
at least one sensor; and
a computing device comprising a first processor and a non-transitory computer-readable medium configured to store program instructions thereon executable by the first processor to cause the computing device to perform functions comprising:
determining, through a first evaluation, whether data received from the at least one sensor indicating movement of the body region corresponds to a spatial movement coherent to a tremor;
for data that is determined to be coherent to a bidimensional tremor, responsively storing the data, the stored data comprising measurements for at least one movement characteristic;
comparing a measurement associated with a latest movement of the body region to an average measurement calculated from at least one prior movement of the body region; and
responsively changing characteristics of the applied electric current if the measurement associated with the latest movement is the same as or greater than the average measurement associated with the at least one prior movement.
