A VAF values for the projection onto the common plane. B Loops on the common plane (solid black: control, self-selected; dashed black: control, slow; blue: FB; red: FE; green: FM). Heel strike, contralateral toe-off, contralateral heel strike and toe-off have been marked with circles, diamonds, triangles, and dots respectively. Slow controls events have been marked in cyan for readability purposes. Loop projections are expressed in arbitrary units. Loop parameters are expressed in normalized arbitrary units
