The present disclosure involves a method of data-reducing and storing a sensation map. A sensation map associated with a patient is provided. The sensation map includes a graphical depiction of a sensation experienced by the patient. The sensation may be pain or paresthesia experienced by the patient in response to an electrical stimulation therapy. A data file is generated. The data file has a data size less than a data size of the sensation map. The data file contains digital information allowing a reconstruction of the sensation map. Electronic communication is then established with an implanted medical device located inside the patient's body. Thereafter, the data file is sent to the implanted medical device for storage. The stored data files are retrievable by another clinician programmer later to reconstruct the sensation map.
