结局指标
主要结局
Estimate the Limits of Agreement Between Observed and Commanded Treadmill Belt Disturbance Parameters: Belt Displacement.
时间窗: Duration of participant test session (approximately 2 hours)
Treadmill belt displacement (cm) will be measured with a Motion Capture system for each perturbation trial and compared to the commanded magnitude to assess system accuracy. Mean observed treadmill belt displacement, in centimeters, relative to commended treadmill belt displacement was calculated and the mean relative error (percentage) was reported. Percent Error = (Commanded Kinematic Value - Observed Kinematic Value)/Commanded Kinematic Value \*100%. The mean value is then determined from the individual errors for each participant. This results in Mean Relative Error. Lower numbers are considered a better outcome (less error). A negative percentage indicates that the observed value is larger than the command value.
Estimate the Limits of Agreement Between Observed and Commanded Treadmill Belt Disturbance Parameters: Peak Velocity.
时间窗: Duration of participant test session (approximately 2 hours)
Treadmill belt peak velocity (cm/s) will be measured with a Motion Capture system for each perturbation trial and compared to the commanded magnitude to assess system accuracy. Mean observed treadmill belt peak velocity, in centimeters/second, relative to commended treadmill belt peak velocity was calculated and the mean relative error (percentage) was reported. Percent Error = (Commanded Kinematic Value - Observed Kinematic Value)/Commanded Kinematic Value \*100%. The mean value is then determined from the individual errors for each participant. This results in Mean Relative Error. Lower numbers are considered a better outcome (less error). A negative percentage indicates that the observed value is larger than the command value.
Estimate the Limits of Agreement Between Observed and Commanded Treadmill Belt Disturbance Parameters: Average Initial Acceleration.
时间窗: Duration of participant test session (approximately 2 hours)
Treadmill belt average initial acceleration (cm/s/s) will be measured with a Motion Capture system for each perturbation trial and compared to the commanded magnitude to assess system accuracy. Mean observed treadmill belt average initial acceleration, in centimeters/second/second, relative to commended treadmill belt average initial acceleration was calculated and the mean relative error (percentage) was reported. Percent Error = (Commanded Kinematic Value - Observed Kinematic Value)/Commanded Kinematic Value \*100%. The mean value is then determined from the individual errors for each participant. This results in Mean Relative Error. Lower numbers are considered a better outcome (less error). A negative percentage indicates that the observed value is larger than the command value.
