Method and Interpretation Boundary

Note: These values are motion-derived muscle-contribution proxies inferred from kinematic channels. They are not EMG measurements. Peak values are used only to locate timing events; report comparison focuses on mean contribution and duty duration because summary peak values can saturate.
