摘要：
The invention is directed to a trial stimulation system and, more particularly, an indicator device within the trial stimulation system that measures and indicates energy amplitude levels for electrical stimulation therapy delivered to a patient. Specifically, the indicator device simultaneously indicates energy amplitude levels, such as electrical voltage, current, power, and electrical charge, as well as the polarity for each electrode in real-time without affecting the therapy delivered to the patient. For example, the indicator device may activate a number of lights in an array of lights in proportion to the measured energy amplitude level for each electrode and may activate a green LED or a red LED when a corresponding electrodes acts as a source or sink, respectively. In this manner, the indicator device allows a clinician to visualize the electrical fields produced by each electrode and, therefore, may assist stimulation steering, trouble shooting, and lead placement.
