Medical evaluation system and method using sensors in mobile devices
First Claim
1. A mobile computing device comprising:
- an alarm indicator,a motion sensor that detects motion of the patient and generates sensory data representing the patient motion,a computer processor configured to;
extract medically relevant data from the sensory data, the relevant data including one or more features of interest in the sensory data,derive one or more surrogate biomarkers from the relevant data, the surrogate biomarkers representative of at least one of a state of a medical condition or a progression of a medical condition of the patient,identify the patient as a specific patient; and
provide a real-time intervention alarm through the alarm indicator when the surrogate biomarkers approach a danger level or threshold that indicates a likelihood of an adverse event occurring to the patient, wherein the real-time intervention alarm is provided prior to the occurrence of the adverse event,wherein the real-time intervention alarm is based on one or more changes in the relevant data and includes a notification directing the patient to change a current activity of the patient.

Abstract
A medical evaluation system includes an I/O module, a processing module, and an analysis module. The I/O module receives sensory data obtained by a motion sensor disposed in a mobile device carried by a patient at least when the patient is in a non-clinical environment. The processing module extracts medically relevant data from the sensory data received from the sensor in the mobile device. The relevant data includes one or more features of interest in the sensory data. The analysis module derives one or more surrogate biomarkers from the relevant data. The surrogate biomarkers represent at least one of a state or a progression of a medical condition of the patient. The mobile device may be a mobile phone carried by the patient and the sensor may include at least one of an accelerometer or a gyroscope that generates the sensory data to represent movements of the patient.

11. A method comprising:
-
a mobile computing device measuring sensory data representative of movement of a patient using a motion sensor of the mobile computing device when carried by the patient in a non-clinical environment; with the mobile computing device, extracting the medically relevant data from the sensory data by identifying one or more features of interest in the sensory data; deriving a surrogate biomarker from the relevant data, wherein the surrogate biomarker represents at least one of a state or a progression of the medical condition of the patient; identifying the patient as a specific patient; and providing a real-time intervention alarm through an alarm indicator coupled to the computing device when the surrogate biomarkers approach a danger level or threshold that indicates a likelihood of an adverse event occurring to the patient, wherein the real-time intervention alarm is provided prior to the occurrence of the adverse event, wherein the real-time intervention alarm is based on one or more changes in the relevant data and includes a notification directing the patient to change a current activity of the patient. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)

20. A non-transitory computer readable storage medium having stored thereon one or more sets of instructions that direct a mobile computing device to:
-
receive sensory data obtained by a motion sensor in the mobile computing device while the mobile computing device is carried by a patient in a non-clinical environment; extract medically relevant data from the sensory data by identifying one or more features of interest in the sensory data; derive a surrogate biomarker from the relevant data, wherein the surrogate biomarker represents of at least one of a state of a medical condition or a progression of a medical condition of the patient; identify the patient as a specific patient; and provide a real-time intervention alarm through an alarm indicator coupled to the mobile computing device when the surrogate biomarkers approach a danger level or threshold that indicates a likelihood of an adverse event occurring to the patient, wherein the real-time intervention alarm is provided prior to the occurrence of the adverse event, wherein the real-time intervention alarm is based on one or more changes in the relevant data and includes a notification directing the patient to change a current activity of the patient. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33)
