Various embodiments described herein relate to detecting motion disorder symptoms based on sensor data.
Mobile communications networks are in the process of offering increasingly sophisticated capabilities associated with the motion sensing of a mobile device. New software applications, such as those related to physical activity, symptom monitoring, prescription administration, and the like, may utilize motion sensors to provide new features and services to consumers. For example, to facilitate dose usage control for a motion disorder (e.g., Parkinson's Disease, Multiple Sclerosis, etc.) patient in an ambulatory setting, various sensors worn by the patient can detect the presence and severity of the patient's symptoms. Because the dosage of the patient's medication depends on the detected symptoms, it is important to detect those symptoms accurately. However, activities of daily life (ADLs) that the patient is engaged in can be confused with motion disorder symptoms and/or make it difficult to accurately quantify the severity of the symptoms.

As noted above, mobile communications networks are in the process of offering increasingly sophisticated capabilities associated with the motion sensing of a mobile device. New software applications, such as those related to physical activity, symptom monitoring, prescription administration, and the like, may utilize motion sensors to provide new features and services to consumers. For example, to facilitate dose usage control for a user with a motion disorder (e.g., Parkinson's Disease, Multiple Sclerosis, etc.), the user can wear various sensors that can detect the presence and severity of the user's symptoms.
The mobile device 102 may also be in communication with a local personal computer, such as laptop computer 112, which may belong to the same user or a third-party monitoring the health of the user. Additionally, the mobile device 102 may be able to connect to the Internet 120 in various ways, such as over a cellular network, a Wi-Fi or other wireless local area network (WLAN), etc. The mobile device 102 may also be able to communicate with one or more third-party servers 122 via the Internet 120.
The mobile device 200 may include one or more transceiver(s) 206 that may be connected to one or more antennas 202. Where the mobile device 200 corresponds to the mobile device 102, at least one of the one or more transceivers 206 may comprise suitable devices, hardware, and/or software for communicating with and/or detecting signals to/from the wrist sensor 104, the ankle sensor 106, and/or the laptop computer 112. Likewise, at least one of the one or more transceivers 206 may comprise suitable devices, hardware, and/or software for communicating over the Internet 120. Alternatively, where the mobile device 200 corresponds to one or more of the wrist sensor 104 and the ankle sensor 106, at least one of the one or more transceivers 206 may comprise suitable devices, hardware, and/or software for communicating with and/or detecting signals to/from the mobile device 102.
One or more motion sensors 212 may be coupled to a processor 210 to provide movement and/or orientation information of the mobile device 200. By way of example, the one or more motion sensors 212 may utilize an accelerometer (e.g., a microelectromechanical system (MEMS) device), a gyroscope, a geomagnetic sensor (e.g., a compass), an altimeter (e.g., a barometric pressure altimeter), and/or any other type of movement detection sensor. Moreover, the one or more motion sensors 212 may include a plurality of different types of devices and combine their outputs in order to provide motion information. For example, the one or more motion sensors 212 may use a combination of a multi-axis accelerometer and orientation sensors to provide the ability to compute positions in two-dimensional and/or three-dimensional coordinate systems.
The processor 210 may include one or more microprocessors, microcontrollers, and/or digital signal processors that provide processing functions, as well as other calculation and control functionality. The processor 210 may also include memory 214 for storing data and software instructions for executing programmed functionality within the mobile device 200. The memory 214 may be on-board the processor 210 (e.g., within the same integrated circuit (IC) package), and/or the memory 214 may be external memory to the processor 210 and functionally coupled over a data bus. The functional details associated with aspects of the disclosure will be discussed in more detail below.
A number of software modules and data tables may reside in memory 214 and be utilized by the processor 210 in order to manage both communications and the detection of motion disorder symptoms based on sensor data. As illustrated in
It should be appreciated that the organization of the memory 214 contents as shown in
The mobile device 200 may further include a user interface 250 that provides any suitable interface systems, such as a microphone/speaker 252, keypad 254, and display 256 that allows user interaction with the mobile device 200.

The display 256 comprises any suitable display, such as, for example, a backlit liquid crystal display (LCD), and may further include a touch screen display for additional user input modes. As shown in
The various embodiments may be implemented at least partially on any of a variety of commercially available server devices, such as server 122 illustrated in
In an embodiment, the large capacity nonvolatile memory 303 may include an optional motion disorder symptom scoring module 328. The motion disorder symptom scoring module 328 is optional because, while it may reside on the server 122, it may alternatively reside on the mobile device 102. Note that although the optional motion disorder symptom scoring module 328 is illustrated as being an executable module stored in the large capacity nonvolatile memory 303, it may be provided in firmware or as a logic circuit within the processor 301.
As noted above, given a user with a motion disorder, because the dosage of the user's medication depends on the detected symptoms, it is important to detect those symptoms accurately. However, ADLs that the user is engaged in can be confused with motion disorder symptoms and/or make it difficult to accurately quantify the severity of the symptoms. Accordingly, the present disclosure provides a method and apparatus for more accurately detecting motion disorder symptoms based on sensor data.
In an embodiment, only ADLs that are relevant to the user's motion disorder may be detected. Regarding which ADLs to detect, there are three criteria indicating the relevance of the ADL to the user's motion disorder:
1. Activities that are of statistical importance
2. Activities that last more than five minutes when they occur, for example, dyskinesia lasts for at least 10 minutes when it occurs
3. Activities that can cause confusion with tremors or dyskinesia
Examples of activities that fit all three criteria include walking (relevant to dyskinesia) and driving (relevant to tremors). Examples of activities that fit two criteria include dish washing, typing on a keyboard, and possibly dressing. Examples of activities that fit one criterion include drinking, folding laundry, cutting food, combing hair, and bagging groceries.
At 404, the operation of classifying the detected ADLs is performed. With reference to
At 406, a regression analysis is performed on the classified ADLs to calculate a severity score of the user's motion disorder symptoms. With reference to
At 408, based on the combination of the severity score of the motion disorder symptoms and the probability that the classification of the ADL is correct, an estimated severity score of the user's motion disorder is calculated. Referring to
Based on the determined severity, the amount of the user's medication(s) can be adjusted. In an embodiment, the user may be instructed to change his or her medication via the user interface of the mobile device 102 or the laptop computer 112. Alternatively, the user may be contacted by medical staff personnel with the instructions, and if necessary, an updated prescription.
As noted above, the motion disorder symptom scoring model 228 is an optional component of the mobile device 200. In an embodiment, where the mobile device 200 corresponds to the mobile device 102, rather than be a component of the mobile device 200, it may be a component of the laptop computer 112 or the server 122, where the laptop computer 112 and/or the server 122 belong to medical personnel or a medical facility responsible for the user's care. In another embodiment, where the mobile device 200 corresponds to one of the wrist sensor 104 or the ankle sensor 106, rather than be a component of the mobile device 200, the motion disorder symptom scoring model 228 may be a component of the mobile device 102.

Alternatively, where the mobile device 200 corresponds to the wrist sensor 104 or the ankle sensor 106, the motion disorder symptom scoring module 228 may be a component of the mobile device 102. As another alternative, the mobile device 200, for example, the transceiver 206, may provide the sensor data and the one or more probabilities to the motion disorder symptom scoring module 328 on the server 300.
