The population of this research consists of individuals between the ages of 18-65 with MS disease. MS patients to be included in the study will be directed by the Neurology outpatient clinic of Sanko University Hospital. All volunteers who agreed to participate in this randomized controlled pretest-posttest design study and met the sample criteria will be included in the study.Individuals who agree to participate will be divided into three groups by simple random method and closed envelope method. Vestibular exercise training group will be formed as Group 1 and Cervical stabilization exercise training group as Group 2, control group, and Group 3 as control group.Functional reach test, tandem stand test, 25 step walking test scale form, Multiple Sclerosis Quality of Life Scale form ( MSQOL-54),Fatigue Impact Scale,Beck depression inventory, MS walking scale (msys-12), dizziness disability inventory, four step square test, timed sit and stand test

, 2 minutes walking test be performed before and after treatment,

Group 1: Vestibular exercise training will be given in addition to conventional treatment (including TENS, electrical stimulation and normal joint range of motion exercises) for 12 weeks. Cawthorne-Cooksey Exercises will be given as a treatment protocol for vestibular exercise training.

Group 2 :Cervical stabilization exercise training will be given in addition to conventional treatment (including Tens, electrical stimulation and normal range of motion exercises) for 12 weeks. Cervical stabilization training improves the sense of cervical proprioception as well as strength and endurance, thereby reducing joint position sense error. Cervical stabilization exercises and training, consisting of 3 stages with increasing difficulty level, will be applied.

Group3: Classical balance exercise training will be given to the control group in addition to conventional treatment (including Tens, electrical stimulation and normal range of motion exercises) for 12 weeks. These exercises were selected among the exercises routinely used in balance rehabilitation in the literature and clinic.

Balance exercise program: walking on tiptoe and heel, walking straight and diagonally on the line, standing on a balance board, supine/prone rolling on the rehabilitation ball, pelvis control in the sagittal and frontal planes on the rehabilitation ball, prone balance on the rehabilitation ball, walking on mats of different softness , was created from side walking exercises.
