The biosensor for monitoring gait in multiple sclerosis (lat. Sclerosis multiplex) was developed by American scientists from the Department of Kinesiology and Community Health, the University of Illinois at Urbana-Champaign. Currently, in the world, there are, according to various estimates, about 3 million patients with multiple sclerosis. Of these, about 450 thousand in Europe, more than 350 thousand in the United States. Gait disturbance is a common symptom in patients with multiple sclerosis and for the treatment of this disease, it is necessary to analyze the gait of patients who often live away from the clinic.
