Comparing the agreement between AID-FOG and gold-standard expert annotation to detect the percentage of time spent with freezing of gait (FOG) in relation to total time duration (%TF).
Ramy czasowe: T0=test day 1: free-living gait assessment (5 hours), T1=test day 2: free-living gait (5 hours) and T2= test day 3: standardized gait (4 hours)
|
The primary outcome (percentage of time spent with FOG in relation to total task duration = %TF) will be established by manual annotations of video footage by an experienced assessor (=gold-standard reference) and by the automated AID-FOG algorithm v1.0 applied post-hoc (i.e.
offline) to IMU data collected during the same walking tasks.
This will be calculated for standardized walking tasks on which the AID-FOG algorithm has been trained, standardized walking tasks on which the AID-FOG algorithm was not trained, and a free-living walking condition on which the AID-FOG algorithm was not trained.

This study investigates the performance of AID-FOG in discriminating between these manifestations, using expert annotations as the reference standard.

Ramy czasowe: T0=test day 1: free-living gait assessment (5 hours), T1=test day 2: free-living gait (5 hours) and T2= test day 3: standardized gait (4 hours)
|
The FOG outcomes as obtained by the human expert and the offline AID-FOG algorithm v1.0 will be calculated for both the OFF and ON medication states.
These scores will be compared to evaluate the change in algorithm performance depending on medication status.
The FOG outcomes will be the percentage TF which ranges between 0-100 percent.
The higher the percentage the more freezing the patient has.
But also the F1-score which ranges between 0-1.
The higher the score the more overlap there is between the expert and the algorithm.
