In MS, the immune system attacks nerve cells in the brain, spinal cord and optic nerves. This disease activity can cause symptoms and disability.
Physical disability gets worse (progression) when disease activity causes more and more nerve cells to die (neurodegeneration)
People may experience disability in different ways, depending on what part of the brain, spinal cord or optic nerves is affected.
Measures the degree of physical disability based on a neurological exam of seven functional systems throughout the body, plus a person’s walking ability. It is a clinical rating scale used to assess disability in MS.
Measures arm, wrist and hand function by timing the speed in which a person can move nine pegs into nine holes and then remove them, using one hand at a time.
Determines walking speed by measuring how fast a person with MS can walk 25 feet.
