Figure 1

A representation of trigger timing for each gait phase. Purple, red, and green arrows illustrate the percentage delay added to gait phase onset for T2 (25% gait phase duration), T3 (50% gait phase duration), and T4 (75% gait phase duration), respectively. T2–T4 triggered stimulation (stim) for the upcoming phase. The same trigger condition was applied to all gait phases. T2, 25% gait phase duration delay trigger; T3, 50% gait phase duration delay trigger; T4, 75% gait phase duration delay trigger. LR—Loading Response, MSt—Mid-Stance, TSt—Terminal Stance, PSw—Pre-Swing, ISw—Initial Swing, MSw—Mid-Swing, TSw—Terminal Swing.
