Patients with MS between 0-5,5 score according to the Extended Disability Status Scale (EDSS) will be included in the study. The balance, gait, position sense, and muscle strength will be evaluated. The study was designed as a prospective, randomized controlled study. The patients will be randomly assigned to two groups, the "Pilates training" group, and the control group. Pilates training will be performed by the Pilates training group 2 times for 8 weeks under supervision in the outpatient clinic. The control group will be taught relaxation exercises and will be asked to perform the exercises 2 times for 8 weeks at home. Statistical analyses will be performed using the SPSS software version 15 (SPSS Inc. Chicago, IL, USA). The pre-training and post-training measurements of groups will be compared with the paired sample t-test.
