Twenty-four patients of both sexes will be recruited, evaluated and treated at the Multiple Sclerosis UOS of the Fondazione Policlinico Universitario Agostino Gemelli IRCCS in Rome from the date of approval of the study by the ethics committee and for the following 12 months, meeting the inclusion criteria. Patients will be divided into two groups by randomisation: one group (experimental group, HO, Hunova-Observation) will perform specific rehabilitation for balance disorder using the robotic platform Hunova® Movendo Technology srl, Genova, IT), followed by 4 weeks of observation. The other group (OH, Observation-Hunova) will instead carry out 4 weeks of observation, at the end of which they will carry out the specific treatment for the balance disorder using the robotic platform Hunova® Movendo Technology srl, Genova, IT).
