The study will include 80 patients (age<65 years) with a diagnosis of MS relapsing remitted according to the McDonald criteria and with an Expanded Disability Status Scale score≤6.0. Patients will be divided into 2 groups, according to a randomization design. The experimental group will undergo a specific training program aimed at increasing balance ability in several sensory conflict conditions. The training program will consist of fifteen 50-minute sessions over a 5 week period (3 sessions/week). The control group will undergo conventional neurorehabilitation treatment following the same pattern of sessions as the study group. At recruitment, after treatment (5 weeks) and in the follow-up (1 month), each patient will be tested with the following clinical and instrumental procedures: Berg Balance Scale, Activities-specific Balance Confidence Scale, Fatigue Severity Scale, Postural Transfers evaluation, Multiple Sclerosis Quality Of Life (MSQOL)-54 instrument, Sensory Organization Test, GAITRite® System and platform stabilometry.
