PIADS Subscores: Difference from FES to cfAFO subscores shown. Preference for FES indicated by Participants 1,4,8,10, otherwise cfAFO. With the exception of Participant 2 and Adaptability subscore for Participant 4, PIADS Subscores differences match with device preference (positive score on chart indicates higher/better Subscore for FES, negative indicates higher/better for cfAFO). MDC of 2.1 or higher met only in Participant 4, Competence and Adaptability.

 

 

MSWS Score Differences Between Interventions:  Lower scores are more favorable. Changes meeting meaningful change 0f 8 are highlighted in red.

MFIS Scores: Lower scores are more favorable. Only participant 11 met the MDC, when comparing cfAFO either Basline or FES. This aligns with participant 11 preference for cfAFO.
Functional Gait Assessment (FGA) Score Differences Between Interventions: Higher scores are more favorable. Changes meeting MCID of at least 4 are highlighted in red.

Total 6MWT Distances:  Preference for FES indicated by Participants 1,4,8,10, otherwise cfAFO.

 

MINIMUM FOOT CLEARANCE VISUALIZATIONS

 

 

 

 

Animation of Minimum Foot Clearance Method: 3D Scan + Inertial Measurement (IMU) Trajectory. Maroon point is true lowest point on shoe during swing. Orange point = toe, yellow point = heel, gray point = center of IMU.

 

Minimum Foot Clearance Gaussian Heatmaps with Histograms: each representing location on foot of lowest point during late-swing in last minute of 6MWT. Key provided for density heatmap at far right of figure.
