Illustration of the participant setup in the laboratory assessment (marker configuration used that included a marker cluster on the lower back and markers placed on the dorsal aspect of second metatarsal head and heel of each foot) and the multi-sensor system worn during the unsupervised assessment, that consisted of IMUs on the lower back and both feet, as well as 16-point pressure insole in each shoe and infrared time-of-flight distance on both legs (at a comfortable height above the medial malleolus)
