Primary Outcome Measures:
  • Subjective fatigue (FSS) [ Time Frame: Weeks ]
  • Maximal voluntary isometric contraction, central activation before and after exercise [ Time Frame: at the time of investigation ]
  • Digit Symbol-Coding scores [ Time Frame: Weeks ]
  • Changes in normal appearing white matter and normal appearing gray matter (MRS-, MTI- and DTI- parameters) [ Time Frame: at the time of MRI ]
  • Cortical atrophy [ Time Frame: at the time of MRI ]
  • Intracortical inhibition/facilitation determined by transcranial magnetic stimulation (+/- 3,4-diaminopyridine) [ Time Frame: at the time of investigation ]

Secondary Outcome Measures:
  • Subjective fatigue (MFI-20, Danish version) [ Time Frame: Weeks ]
  • Rapid voluntary twitches [ Time Frame: at the time of investigation ]
  • 6 minute walk test [ Time Frame: at the time of investigation ]
  • 9-hole peg test [ Time Frame: at the time of investigation ]
  • WAIS/WMS tests [ Time Frame: at the time of investigation ]
  • WHO-5 Questionnaire [ Time Frame: at the time of investigation ]
  • Major Depression Inventory [ Time Frame: at the time of investigation ]
  • Lesion load [ Time Frame: at the time of MRI ]
  • Whole brain atrophy [ Time Frame: at the time of MRI ]
  • Subjective fatigue (VAS) [ Time Frame: at the time of investigation ]
