Abstract
Introduced here are techniques for digitally characterizing the movement of a subject in order to detect the presence of a disorder or monitor the progression of the disorder. More specifically, one or more angular features can be identified that define how certain part(s) of the human body move relative to other part(s) of the human body. These angular feature(s) can be used, for example, to affirmatively diagnose instances of a disorder, eliminate a disorder as the source of symptoms experienced by a subject, generate confidence scores that can be used to assist in diagnosing a subject, monitor disorder progression due to treatment or lack thereof, etc.
Claims20
A non-transitory medium with instructions stored thereon that, when executed by a processor of a computing device, cause the computing device to perform operations comprising:
- acquiring data that is generated by an inertial sensor that is located proximate to a first person while the first person performs an activity;
- computing, based on an analysis of the data, a first set of values for an angular feature that is defined by a spatial relationship between a first body part, a second body part, and a third body part of the first person;
- and
- determining whether to diagnose the first person as having a disorder based on statistical similarity between the first set of values and a second set of values of the angular feature,
- wherein the second set of values corresponds to a performance of the activity by a second person who is known to represent a confirmed case of the disorder.
A method comprising:
- examining, by a processor, data that is generated by an inertial sensor that is located proximate to a person while the person performs an activity, so as to establish movements of a first anatomical location of the person and a second anatomical location of the person with respect to a third anatomical location of the person;
- computing, by the processor, a first set of values for an angular feature during the performance of the activity,
- wherein the angular feature is defined by a spatial relationship between the first and second anatomical locations with respect to the third anatomical location;
- and
- determining, by the processor, whether to diagnose the person as having a disorder by comparing the first set of values to a second set of values of the angular feature,
- wherein the second set of values is representative of at least one confirmed case of the disorder.
A non-transitory medium with instructions stored thereon that, when executed by a processor of a computing device, cause the computing device to perform operations comprising:
- obtaining data generated through visual tracking of movement of multiple anatomical regions of an individual while the individual performs an activity during a first session;
- computing, based on the data, a first set of values for an angular feature that is defined by a spatial relationship between the multiple anatomical regions of the individual;
- estimating a measure for disorder progression by comparing the first set of values to a second set of values of the angular feature,
- wherein the second set of values corresponds to a prior performance of the activity by the individual during a second session that precedes the first session;
- and
- stratify the individual into a treatment program based on the measure.
