The range of the intensity allowed by the device is 0-50milliamperes (mA).

FES will be applied using an advanced software that is able to synchronize muscle activation with the time of perturbation onset and according to the phases of gait.\n\nThis project design aims to examine whether a specific pattern of lower limb muscle stimulation could improve the kinematic and behavioral responses during reactive balance following slip- and trip-like perturbations. Additionally, the project aims to see if the kinematic and spatio-temporal gait parameters can be modified during a standardized walking test under different sensory and environmental conditions.",[78],"Chronic Stroke",[80,81,82,83,84,85,86,87],"functional electrical stimulation","neuromuscular electrical stimulation","walk-training","treadmill training","reactive balance","perturbation","falls","fall prevention","2026-05-20",{"date":90,"type":91},"2026-05-22","ACTUAL",{"date":93,"type":91},"2021-05-15",{"date":95,"type":72},"2027-11-30",{"name":5,"class":6},1]
