Registered outcomes6

Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.

List	Outcome	Time frame	Description
Primary	Change in Postural Sway After 10 Min of Walking	Baseline, 10 minutes	Magnitude of side-to-side postural sway
Primary	Change in Kinematic Variability After 10 Min of Walking	Baseline, 10 minutes	Magnitude of step-to-step corrections in step width measured in cm
Primary	Change in Foot Placement Targeting Accuracy After 10 Min of Walking	Baseline, 10 minutes	Accuracy of performing foot placement targeting task. i.e., distance between heel marker at initial contact and target line (measured using three-dimensional motion capture during walking).
Secondary	Change in Cognitive-motor Interference Accuracy After 10 Min of Walking	Baseline, 10 minutes	Accuracy performing an auditory stroop test (cognitive dual-task)
Secondary	Change in Cognitive-motor Interference Response Time After 10 Min of Walking	Baseline, 10 minutes	Response time in performing an auditory stroop test (cognitive dual-task)
Secondary	Change in Margin of Stability Variability After 10 Min of Walking	Baseline, 10 minutes	Change in step-to-step fluctuations in margin of stability (the distance between the lateral boundary of the foot and the body's center of mass, measured in cm)

Outcomes6

Each outcome the trial posted results for, in ClinicalTrials.gov's words.

Type	Outcome	Time frame	Population	Units	Measured as
PRIMARY	Change in Postural Sway After 10 Min of Walking	Baseline, 10 minutes		cm	MEAN
PRIMARY	Change in Kinematic Variability After 10 Min of Walking	Baseline, 10 minutes		cm	MEAN
PRIMARY	Change in Foot Placement Targeting Accuracy After 10 Min of Walking	Baseline, 10 minutes	Data could not be collected because motion capture markers tracking the location of the targeting device were too often obstructed to be able to reliably estimate foot placement targeting accuracy.
SECONDARY	Change in Cognitive-motor Interference Accuracy After 10 Min of Walking	Baseline, 10 minutes	Data could not be collected because noise from the treadmill motor interfered with the collection of auditory stroop test responses.
SECONDARY	Change in Cognitive-motor Interference Response Time After 10 Min of Walking	Baseline, 10 minutes	Data could not be collected because noise from the treadmill motor interfered with the collection of auditory stroop test responses.
SECONDARY	Change in Margin of Stability Variability After 10 Min of Walking	Baseline, 10 minutes		cm	MEAN
