What is the functional system score for multiple sclerosis?

ANSWER

On a scale of 0 to 6, your functional system score (FSS) measures how well your major central nervous systems are working and assigns a score to your disability. This score uses information about your gait and use of assistive devices. It also involves observation of:

  • Weakness or trouble moving limbs
  • Tremor or loss of coordination
  • Problems with speech, swallowing, or involuntary eye movements
  • Numbness or loss of sensation
  • Bowel and bladder function
  • Visual function
  • Mental functions
