Fig. 2From: Regularity of kinematic data between single and dual-task treadmill walking in people with Parkinson’s diseaseThe SampEn of the least-affected (left column) and most-affected (right column) foot angular velocity (FootAV) in the ML (top row), AP (middle row), and V (bottom row) directions versus time scale for single-task (ST) and dual-task (DT) walking condition. Scales highlighted in green elicited significant increase (p < 0.05) in SampEn from ST to DTBack to article page
