Group A will receive both balance training and cognitive rehabilitation twice a week for 12 weeks and each session will last for 1 hour.

Group B will receive only balance training twice a week for 12 weeks and each session will last for 1 hour.

• The balance training will be given for 12 weeks (2 sessions/week, 30-35 in each) that included six balance exercises per training session.
• After 5-min warm-up program including general (e.g., neck rolls, shoulder circles, side bends, hip circles, marsh in place) and specific (e.g., two-/one-legged stance on unstable devices, forward/backward beam walking).
• Two sets per balance exercise will be performed for 30s each with a 60s rest period between sets and a 90 s break between exercises. Yet, both groups will execute the same training volume (i.e., number of exercises, number of sets per exercise, and duration per set of exercise).
• Progression during training will be achieved by means of increasing exercise duration (i.e., from 30s over 45s to 60 s), change of stance (i.e., two-legged stance, tandem. stance, one-legged stance) and walking (i.e., forward, backward) condition, manipulation of visual input (e.g., eyes opened vs. closed), and concurrent execution of cognitive

• For Cognitive Impairment: This outcome measurement tool will be used for assessment of cognitive impairment. In patients with multiple sclerosis.MoCA is a screening instrument that evaluates seven cognitive domains on a single page and scores range from 0 to 30. The domains are: visuospatial/executive functions, naming, verbal memory registration and learning, attention, abstraction, 5-minute delayed verbal memory, and orientation.(24) The MoCA scoring suggested a cutoff score of 26, with those scoring 25 or below suspected of having (MCI).(24)MoCA had demonstrated an excellent diagnostic validity of 0.89 (95% CI: 0.83-0.95)(25).The inter-rater reliability or an ICC value of MoCA was 0.96 (95% CI: 0.91-0.98.

• For Balance assessment: This outcome measurement tool will be used for assessment of Balance in patients with multiple sclerosis. The BBS contains 14 static and dynamic balance activities related to daily life. The BBS tasks progress in challenges: from sitting to standing, standing with narrow base of support, and finally to tandem and single-leg stance. Scoring is on a 5-point ordinal scale with 0 indicating an inability to complete the task and 4 as independent with completing the task.(22).The maximum score of 56 indicates good balance. The scale takes approximately 10 to 20 minutes to complete requiring minimal equipment (chair, stopwatch, ruler, and step) and minimal space.(22)The score of 56 indicates the normal functional balance.(22).The score less than 45 will indicates the higher risk of fall due to impaired balance.(22).The validity of the BBS is (7 = -0.50, P <.001,4 and r = -0.58, P < 005).(26).BBS had strong test-retest reliability (ICC = 0.90).26

• For assessment of Quality of life: A 36-item short-form (SF-36) was constructed to survey health status and quality of life. The SF-36 includes one multi-item scale that assesses eight health concepts: 1) limitations in physical activities because of health assesses eight health concepts: 1) limitations in physical activities because of health problems; 2) limitations in social activities because of physical or emotional problems; 3) limitations in usual role activities because of physical health problems; 4) bodily pain; 5) general mental health (psychological distress and well-being); 6) limitations in usual role activities because of emotional problems; 7) vitality (energy and fatigue); and 8) general health perceptions. The survey is constructed for self-administration by persons 14 years of age and older, and for administration by a trained therapist as well.(27).The items are categorized, totaled, and converted into a scale ranging from 0 (the worst condition of health) to 100
