Fig. 1From: Random forest algorithms to classify frailty and falling history in seniors using plantar pressure measurement insoles: a large-scale feasibility studyOverview of the 7-sensor plantar pressure measurement insole device and output. A: Seven pressure sensors are inserted in a 2 mm-thick hygienic shoe insole. The insole is inserted in a commercial Velcro shoe, and the data acquisition unit is attached using an additional piece of Velcro on the tong. B: A five-second example of plantar pressure data was collected from a walking testBack to article page
