Effect of Aerobic Training vs Balance Training on Fatigue Symptom in Multiple Sclerosis Patient (FATI-gate)

Aerobic training: 15 daily sessions (5 sessions per week), each lasting approximately 90 minutes. Sessions will be performed with the assistance or supervision of a physical therapist and will consist of the following steps: 1) warm up with a stationary bike (no load, 10 min, 60 cycles/min); 2) upper and lower limb stretching (10 min); 3) 10 min rest in a sitting position; 4) first exercise bout: stationary bike, 15 min, 60 cycles/min (the load will be modulated so that the participant's heart rate is between 60 and 70% of the estimated maximum heart rate, and the patient perceives moderate fatigue on the Borg Rating of Perceived Exertion; 5) upper and lower limb stretching (10 min); 6) 10 min rest in a sitting position; 7) second exercise bout (same parameters as the first exercise bout); 8) upper and lower limb stretching (10 min).

Balance training: 15 daily sessions (5 sessions per week), each lasting approximately 90 minutes. Treatments will be performed with a physical therapist and will consist of the following exercises: 1) standing with feet together, 2) standing with closed eyes, 3) standing on unstable surfaces, 4) standing while performing upper limbs movements; 5) standing while performing head rotations; 6) walking on a treadmill at alternating speeds; 7) leg press and chest press exercises for training trunk balance during ballistic movements of the upper and lower limbs. These constituents of balance training can be combined in the same task according to the participant's ability.
