Understanding recovery after stroke-related arm weakness using 3D movement tracking
Official title: Dissecting recovery from post-stroke arm paresis with 3D kinematics
Funded at University of California Los Angeles · NIH-11599330 · Data updated 2026-11-12
A new NIH grant aims to measure how people regain arm movement after a stroke using advanced, markerless 3D motion tracking to give clearer, more personalized recovery information.

Who could benefit from this research
✓Could help
Stroke survivors with upper-limb impairment who can attempt reaching tasks and participate in markerless 3D recording sessions.
✕Less likely to help
Individuals without upper-limb impairment from stroke or those unable to participate in movement assessments.
What this research studies
After stroke, arm movement is often limited and traditional scales don’t capture the full quality of motion or subtle improvements. This project will create and test a composite 3D movement score from markerless recordings of reaching tasks in both stroke patients and healthy people, checked over time. By analyzing different aspects of movement, such as strength, dexterity, and compensatory strategies, researchers hope to separate true recovery from compensatory patterns. If successful, the tool could provide clinicians with a sensitive, interpretable measure to guide rehabilitation decisions.
Why it matters
Potential benefit: If successful, patients could receive more personalized rehab plans based on precise 3D movement measurements.
How similar studies have gone: Previous work suggests that detailed kinematic measures can reveal motor deficits not captured by standard scales, but this project aims to validate a clinically usable composite score.
