Quiz #3 SCI / parkinsons/MS Flashcards
MS with ataxia- focus on
Stability
PD with rigidity- focus on
Mobility
Where is the substantia nigra located?
: Basal Ganglia
What are the primary responsibilities of the basal ganglia?
Regulation of posture and movement
What causes the primary symptoms in parkinsons disease?
A decrease in dopamine stored in the substantia nigra
Lesions in the basal ganglia cause

Secondary Parkinsonism occurs as a result
other conditions (encephalitis, alcoholism, exposure to toxins etc)
inability to initiate movement
Akinesia
”: constant resistance to passive limb movement in any direction regardless of speed
Lead-pipe rigidity
causes a catch & release; result of combining lead-pipe rigidity and tremor
Cogwheel”:

Tremor
Gait of a person with PD
shuffling, punctuated by short steps and progressive increase in speed. FESTINATING GAIT
Fatigue contributes to…in PD
postural instability b/c of the difficulty the person with PD experiences while trying to sustain an activity.
