Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Linear parameters: maximum anterior-posterior displacement of the center of pressure, maximum medial-lateral displacement of the center of pressure, and displacement speed of the center of pressure. Timepoint: In this study, during a walking assessment session, subjects are asked to take off their shoes and stand at one end of the approximately 8-meter space of the laboratory, maintaining their usual posture with their hands by their sides. With the examiner's order, at their self-selected speed, they start walking during two stages with and without cognitive tasks for approximately 120 seconds (equivalent to 10 times crossing the force plate) so that only the desired leg is on each time the force plate. Method of measurement: Bertec force plate.;Non-linear parameters: percentage of repeatability, determination, irregularity, and stability of the center of pressure in anterior-posterior and medial-lateral directions. Timepoint: In this study, during a walking assessment session, subjects are asked to take off their shoes and stand at one end of the approximately 8-meter space of the laboratory, maintaining their usual posture with their hands by their sides. With the examiner's order, at their self-selected speed, they start walking during two stages with and without cognitive tasks for approximately 120 seconds (equivalent to 10 times crossing the force plate) so that only the desired leg is on each time the force plate. Method of measurement: Bertec force plate.;Ankle, knee, and hip kinematics in a walking cycle in sagittal, frontal, and horizontal planes. Timepoint: In this study, during a walking assessment session, subjects are asked to take off their shoes and stand at one end of the approximately 8-meter space of the laboratory, maintaining their usual posture with their hands by their sides.
