System and method for quantifying qualitative patient-reported data sets

Methods and apparatuses for collecting and quantifying patient-reported data from a neuromodulator. The patient-reported data typically includes a pain score that quantifies the level of pain experienced by the patient at a particular time. The apparatus can include a user interface that allows the patient to enter such information in real time. The methods and apparatuses can include a correlation process, whereby each patient-reported entry is correlated with a corresponding neuromodulation treatment. This correlation can be used to identify treatment parameters and dosages that are most effective, and to further identify when certain dosages are most effective. This information can further be used as feedback to generate optimized treatments for a specific patient and iteratively improve the treatments. In some cases, the correlation process identifies under reported or over reported data, which can be filtered out to provide more accurate optimized treatments.
