Multiple Sclerosis Flashcards
Who is MS commonly seen in?
Is more common in women than men
What causes MS?
Unknown - Could be genetic of environmental factors
What is MS?
MS is an inflammatory, demyelinating disease of the CNS.
What are some sign and symptoms of MS?
Unilateral optic neuritis, numbness/tingling in limbs; leg weakness; nystagmus
What could we find in clinic in a patient?
Dysaesthesia;loss of vibration sense; trigeminal neuralgia; ataxia; tremor; spastic weakness; myelitis.
Two signs characteristic of MS:
• Uhthoff’s phenomenon
Exacerbation of symptoms due to higher than usual ambient temperatures
Blurred vision during exercise
• Lhermitte’s sign
An electrical sensation that runs down the back when bending the neck
Two main classifications of MS:
- relapsing remitting (80% start this way)
(long periods of remission between acute bouts, may have very slow progression) - a. primary progressive (steady progression - no acute bouts)
b. secondary progressive (acute bouts followed by steady progression)
Pathophysiology of MS
T cells attack myelin, cause an increase in cytokines which damage the oligodendrocytes in the CNS - Patchy inflammatory destruction (scleroses)
Benefits of exercise in MS:
Improves strength
Reduces blood pressure
• Restore balance in production of pro-inflammatory cytokines and
anti-inflammatory cytokines
• Stimulate neurotrophic factors (NGF, BDNF)
• Help with associated disabilities – depression, fatigue
Responses to exercise in MS:
Acute • Overwhelming fatigue! Chronic • Strength and endurance improves • Cytokine balance • Nerve growth factors
Main problems in MS:
- balance, fatigue, spasticity, foot-drop
- May need to use cycle ergometer, toe clips
