Embodiments are directed to identifying and measuring bodily states and feedback systems. A computer system initializes a tracking and measuring device to generate patient data related to a bodily state or feedback system of a patient. The computer system gathers the patient data using the initialized tracking and measuring device, and identifies a baseline parameter used to determine a baseline state relative to the gathered patient data. The computer system further gathers additional patient data using the initialized tracking and measuring device and compares the additional gathered patient data to the identified baseline parameter. Then, if the additional gathered patient data differs from the baseline state by a specified threshold amount, the computer system determines that a change in the patient's bodily state or feedback system has occurred and/or determines the amount of change in the bodily state or feedback systems that has occurred.
