Abstract
A method, system, and computer-readable medium receive module configuration settings to configure a customized human movement examination module for a human movement examination item. A patient is instructed with audio instructions associated with the customized human movement examination module. A single camera is controlled having progressive scan capabilities according to the module configuration settings to allow recording of a performance by the patient of the human movement examination item. The recorded data is analyzed based on the information provided by the single camera to measure human movement exhibited by the patient.
Core Innovation
The invention provides a comprehensive human movement analysis system using a customized human movement examination module configured by module configuration settings to conduct a human movement examination item. Audio instructions associated with the customized human movement examination module instruct a patient with an instruction to begin action, and the system controls a single camera having progressive scan capabilities to record the patient’s performance. The system identifies a specific body appendage of the patient in the recording and analyzes the recording based on movement exhibited by that specific body appendage.
The system further analyzes latency of the patient during the human movement examination item to respond to the instruction to begin action. Module-specific analysis includes extracting objective movement metrics and summary result data from recorded audio-video, and processing the movement exhibited by the specific body appendage through tracking algorithms and signal processing. The resulting summary results are compared to normative standards to support diagnosing human movement disorders.
The invention describes multiple human movement analysis module pipelines, each using recording and tracking/signal processing to generate plots and statistics and produce summary results. These include pipelines for foot/heel tapping, finger tapping/hand flapping, head movement, gait/walking, and example modules such as postural tremor, alternating supination-pronation, finger-to-nose using a hand-cast target, and postural instability.
Claims Coverage
The independent claims are directed to a non-transitory computer-readable medium, a system, and a method. Across these independent claims, the inventive features center on customized module configuration settings, audio instructions including an instruction to begin action, progressive-scan single-camera recording, body-appendage identification, movement-based analysis from the appendage, and latency analysis in response to the begin-action instruction.
Customized human movement examination module configuration and appendage-based movement analysis
Receiving module configuration settings to configure a customized human movement examination module for a human movement examination item; identifying a specific body appendage of the patient in the recording; analyzing the recording based on movement exhibited by the specific body appendage of the patient.
Audio instructions to begin action with latency analysis
Instructing a patient with audio instructions associated with the customized human movement examination module, wherein the audio instructions include an instruction to begin action; and analyzing latency of the patient during the human movement examination item to respond to the instruction to begin action.
Progressive-scan single camera recording controlled by module configuration settings
Controlling a single camera having progressive scan capabilities according to the module configuration settings to allow recording of a performance by the patient of the human movement examination item.
Computing device-implemented customized examination workflow
Receiving, via a computing device, module configuration settings to configure a customized human movement examination module for a human movement examination item; instructing, via the computing device, a patient with audio instructions associated with the customized human movement examination module; controlling, via the computing device, a single camera having progressive scan capabilities according to the module configuration settings to allow recording; identifying a specific body appendage; analyzing the recording based on movement exhibited by the specific body appendage; and analyzing latency in response to the instruction to begin action.
System with computing device controlling single progressive-scan camera and conducting latency-based response to begin action
A system comprising a single camera having progressive scan capabilities and a computing device coupled to the single camera, wherein the computing device is configured to receive module configuration settings, instruct a patient with audio instructions, control the single camera, identify a specific body appendage, analyze the recording based on movement exhibited by the specific body appendage, and analyze latency of the patient in response to an instruction to begin action.
Across the independent claims, the coverage consistently requires configuring a customized human movement examination module via module configuration settings, instructing a patient with audio instructions including an instruction to begin action, recording via a single progressive-scan camera controlled according to the module configuration settings, identifying a specific body appendage and analyzing movement exhibited by that appendage, and analyzing latency in response to the instruction to begin action.
