The control group will be queued to be included in the exercise program and participants' routine treatment will continue.

The exercise will be given as a video and participants will be asked to continue the exercises for 8 weeks, 3 days a week. Patients will be contacted by phone every week to ask if participants have any problems with the exercise program and their compliance.

Exercise will be given as a brochure and participants will be asked to continue the exercises given for 8 weeks, 3 days a week. Visual feedback will be provided by asking participants to mark the exercise tracking chart on the exercise brochures.

Evaluation for severity of fatigue

Timed up and go: Patients wear their regular footwear and can use a walking aid, if needed.

1. The patient starts in a seated position
2. The patient stands up upon therapist's command: walks 3 meters, turns around, walks back to the chair and sits down.
3. The time stops when the patient is seated.
4. Be sure to document the assistive device used. Note: A practice trial should be completed before the timed trial. High falling risk>13.5 seconds.

The 25 steps walking test is a quantitative mobility and leg function performance test based on a timed 25-walk. The patient is directed to one end of a clearly marked 25-foot course and is instructed to walk 25 feet as quickly as possible, but safely. The time is recorded.

The Fatigue Severity Scale questionnaire contains nine statements that rate the severity of fatigue symptoms. A total score of less than 36 suggests that patient may not be suffering from fatigue. A higher score is indicated high level of fatigue.

The Brief International Cognitive Assessment for MS (BICAMS) initiative was undertaken to recommend a brief, cognitive assessment for MS that is optimized for small centers. BICAMS was particularly focused on international use, to facilitate comparison across settings. An expert committee of twelve neurologists and neuropsychologists representing the main cultural groups that have so far contributed extensive data about cognitive dysfunction in MS was convened. The opinions generated from the meeting are published elsewhere. Consensus was also achieved on optimal measures for learning and memory in MS patients, time permitting: the initial learning trials of the second edition of the California Verbal Learning Test (CVLT2) and the revised Brief Visuospatial Memory Test (BVMTR).

The Beck Depression Scale is a 21-item self-reported questionnaire in which each item consists of four statements indicating different levels of severity of a particular symptom experienced over the past week. Scores for all 21 items are summed up to yield a single depression score. Scores of 0-12 are considered in the normal range, 13-18 as mild, 19-28 as moderate, and scores of 29-63 are considered to indicate severe depression.

The Beck Anxiety Scale consists of 21 symptoms that are rated on a four-point severity scale referring to the experience of symptoms over the past week. Scores for the 21 items are summed up to yield a single anxiety score. Scores between 0 and 17 are considered as normal and mild anxiety, whereas scores over 25 are considered as severe anxiety.
