It is an electric exercise machine, equipped with a sliding mat, a seat, a handlebar and other means of support and connection, designed to be used by a person with reduced walking autonomy in order to recover or maintain their mobility. The seat allows the subject to rest or perform exercises in which a work phase is alternated with a recovery phase; the support means allow the subject to get up easily. A device allows the subject to stop the movement of the treadmill by bringing the handlebars close to him or her, either voluntarily or involuntarily in the event of loss of balance. The presentation will be given by Engineer Enrico Proner of the Applied Mechanics Group.
