ML displacement amplitude, timing, and stability of the COM. Examples of the 3 outcome measures in isolation using simulated data (A, B, and C) and observed in nonpathologic (D) and ataxic (E) gait. (A) Amplitude: larger movements representative of reduced dynamic balance. (B) Timing: an out of phase pattern indicative of poor coordination. (C) Stability: unstable movement pattern with high frequency movement reflective of unsteady displacement of the COM. (D) Nonpathologic gait, collected from a woman participant. This pattern possesses a relatively consistent amplitude and timing and is stable, predominantly fluctuating at a constant frequency with little movement variability. (E) BWSTT data collected during a trial performed by a patient with ataxia due to a traumatic brain injury. This pattern has large displacement, inconsistent timing, and poor stability.

3. Fig 2
Displacement, timing, and stability for each of the gait training protocols. Mean ± SD results of the ML COM displacement, timing, and stability assessments for each of the gait training protocols. The horizontal dotted line represents the mean result for the nonpathologic gait pattern, with the gray shaded region the SD. (A) Displacement, (B) timing, and (C) stability.
