A Vision-Based Characterization of Human Movement Scaling in Large-Amplitude Tasks
Sponsor: Biruni University
Summary
This pilot study investigates the feasibility of objectively quantifying movement amplitude and amplitude decay during large-amplitude exercises using RGB camera-based video analysis in healthy volunteers. Six large-amplitude exercises are recorded across repeated trials, with the first repetition clinically confirmed as the individual's maximum reference. Movement amplitude is quantified using pose-based kinematic measures and complemented by an exploratory self-supervised visual transformer approach to characterize repetition-wise changes relative to the reference execution. The study aims to determine whether camera-based methods can detect amplitude decay patterns and identify moments requiring clinical verbal cues, thereby supporting future objective monitoring and feedback in large-amplitude exercise training.

Large-Amplitude Exercise Observation and Video Recording
Participants perform six standardized large-amplitude exercises (Floor-to-Ceiling Reach, Forward Step, Side Step, Sit-to-Stand, Forward Reach to Grasp and Release an Object, and Big Walking). Each exercise is repeated eight times while full-body movement is recorded using an RGB camera. The first repetition of each exercise is clinically confirmed as the participant's maximum movement amplitude and used as a reference for subsequent observational analysis. No therapeutic manipulation or feedback is provided beyond standard verbal confirmation.
