Cooling During Inpatient Rehabilitation in Persons With MS

The goal of this clinical trial is to shed light on the use of cooling during intensive active training sessions during a three-week multidisciplinary inpatient rehabilitation stay in persons with Multiple Sclerosis. The objectives of this study are: * to investigate the effects of one week of using a cooling vest during intensive active training sessions compared with one week of not using a cooling vest during inpatient rehabilitation on the state fatigue in persons with Multiple Sclerosis. * to investigate the effects of one week of using a cooling vest during intensive active training sessions compared with one week of not using a cooling vest during inpatient rehabilitation on the walking capacity, functional lower limb muscle strength, balance and cognition in persons with Multiple Sclerosis. * to investigate the effects of the three-week inpatient rehabilitation on the cardiorespiratory fitness, muscle strength and trait fatigue in persons with Multiple Sclerosis. Researchers will compare the effects of one week of using a cooling vest during intensive active training sessions with one week of not using a cooling vest during intensive active training sessions during three weeks of inpatient rehabilitation. Participants will * Wear a cooling vest during intensive active training sessions for one week * Attend the assessment appointments during study participation * Keep a diary recording their use of a cooling vest during intensive active training sessions
