1. A system for guiding the flow of energy through a subject to stimulate the contraction of muscle tissue, comprising: first and second electrodes adapted to be positioned on the subject and adapted to deliver energy to the subject to stimulate the contraction of muscle tissue;a stimulation control unit in communication with the first and second electrodes and configured to generate stimulating energy adapted to stimulate the contraction of muscle tissue and to deliver the stimulating energy to the first and second electrodes; andan impedance modification element positioned laterally relative to at least one of the first and second electrodes such that it does not extend across an entire width of at least one of the first and second electrodes, wherein the impedance modification element is adapted to increase the impedance of tissue within the subject to reduce lateral spreading of the energy delivered between the first and second electrodes. 2. The system of claim 1 wherein the impedance modification element comprises a cooling element adapted to decrease the temperature of the tissue within the subject to thereby increase the impedance of the tissue within the subject. 3. The system of claim 1 wherein the impedance modification element is positioned laterally on both sides of the first and second electrodes. 4. The system of claim 3 wherein the impedance modification element does not extend across the widths of either the first or second electrodes. 5. The system of claim 4 wherein the impedance modification element comprises a first impedance modification element positioned on a first side of the first and second electrodes and a second impedance modification element not integral with the first impedance modification element positioned on a second side of the first and second electrodes. 6. The system of claim 1 wherein the impedance modification element is positioned solely laterally to the first and second electrodes. 7. The system of claim 6 wherein the impedance modification element comprises a first impedance modification element positioned solely laterally to the first and second electrodes on a first side of the first and second electrodes and a second impedance modification element not integral with the first impedance modification element positioned solely laterally to the first and second electrodes on a second side of the first and second electrodes. 8. The system of claim 1 further including a housing adapted to be positioned on the subject, wherein the housing houses the first and second electrode. 9. The system of claim 8 wherein the electrodes are pre-established in a stimulation pattern within the housing. 10.
