1. A method of treating focal dystonia comprising: a. providing a system comprising a stimulating electrode operably connected with a processor configured to set one or more stimulation parameters for an electrical impulse deliverable by the electrode; b. placing the electrode in operative electrical contact with at least one neuron innervating at least one muscle; c. using the processor to set the stimulation parameters such that the electrical impulse causes a level of stimulation which does not exceed an excitability threshold of one or more alpha motor neurons located within the at least one muscle; and d. delivering the electrical impulse to the at least one neuron, wherein the electrical impulse acts upon one or more gamma motor neurons located within the at least one muscle.
