MOTION ANALYSIS FOR BEHAVIOR IDENTIFICATION

摘要

Devices, systems, and techniques for analyzing video information to objectively identify patient behavior are disclosed. A system may analyze obtained video information of patient motion during a period of time to track one or more anatomical regions through a plurality of frames of the video information and calculate one or more movement parameters of the one or more anatomical regions. The system may also compare the one or more movement parameters to respective criteria for each of a plurality of predetermined patient behaviors and identify the patient behaviors that occurred during the period of time. In some examples, a device may control therapy delivery according to the identified patient behaviors and/or sensed parameters previously calibrated based on the identified patient behaviors.

主权项

1. A method comprising:
obtaining video information of patient motion captured over a period of time, wherein the video information comprises a plurality of frames; receiving, with respect to one frame of the plurality of frames, a selection of a sample area representative of an anatomical region; analyzing, by one or more processors, each of the other plurality of frames for respective areas corresponding to the sample area; calculating, by the one or more processors, one or more movement parameters of the anatomical region during the period of time from at least one difference between the sample area and one or more respective areas of at least a subset of the plurality of frames; comparing, by the one or more processors, the one or more movement parameters of the period of time to respective criteria for each of a plurality of predetermined patient behaviors; and identifying, based on the comparison and by the one or more processors, each one of the predetermined patient behaviors that occurred during the period of time.
