The disclosure describes an implantable stimulation system that guides programming with a therapeutic tree. All possible stimulation parameters are arranged on the therapeutic tree, with each level of the therapeutic tree containing a different stimulation parameter type. Each level includes nodes that are connected to nodes of adjacent levels. A program path is created by moving through nodes of lower levels. The stimulation parameter types are arranged so that coarse adjustments occur at higher levels of the tree and fine adjustments occur at lower levels of the tree. The nodes of the program path define the stimulation parameters of the delivered stimulation therapy. The user may provide information such as efficacy input and/or medication dosage information to the system for identifying the most efficacious program path in treating pain of the patient. Additionally or alternatively, efficacy feedback may be received from physiological parameter sensors.
