Supplementary Fig. S1 — Coordination Trajectory in NW-Fitted UMAP Embedding

INTERACTIVE 2D UMAP N = 10 8 bins / cycle Lee et al. (2026), Journal of NeuroEngineering and Rehabilitation  ·  Companion to manuscript Fig. 1.

How to use: Hover any point for cycle-level coordinates (subject ID, bin index). Use the buttons above the chart to toggle between the bin-wise centroid trajectory and the underlying cycle-level cloud. Drag to zoom, double-click to reset. Click legend entries to hide / show conditions. The right-hand panel reports pooled Walking-Shift Index (WSI) values with 95 % bootstrap percentile intervals.
