As with all neurological diseases, it is important to use appropriate outcome measurements in the assessment of balance and gait disorders in patients with Multiple Sclerosis (MS), in order to determine the appropriate program for the patient in physiotherapy and rehabilitation applications, both face-to-face and through telerehabilitation. The scale recommended by a clinical practice guide developed with the support of the American Physiotherapy Association (APTA) and the Academy of Neurological Physiotherapy (ANPT) is the Functional Gait Assessment (FGA). According to this proposal, a Turkish version will be made within the scope of the study so that functional walking evaluation can be used in our country. A 2017 study on functional gait assessment and Multiple Sclerosis investigated the validity and sensitivity to changes in the original English version of the test in multiple sclerosis, and as a result, its validity was found for MS. Functional gait assessment does not have a reliability study for Multiple Sclerosis.
