Neurology - tremors Flashcards
what is cerebellar ataxia?
- broad based stance
- truncal instability during walking (can cause falls to either side)
- irregular steps
- feet lift too high
what is an intention tremor?
coarse, LOW FREQUENCY oscillation that increases amplitude when reaching the EXTREMITIES of a VISUALLY GUIDED movement
what is a resting tremor not associated with?
voluntary muscle contraction
where in the body can be affected by a resting tremor?
any area supported by gravity
which neurological disease is associated with a resting tremor? what specific type of resting tremor?
parkinsons disease
sometimes with a “pin rolling” action of your hands
When will an essential occur?
when there is voluntary muscle contraction
what is the difference between an essential tremor and other tremors?
it is not associated with other neurological disorders
are there multiple or one tremor in an essential tremor?
either but commonly many different tremors
what will an essential tremor make difficult?
- maintaining posture
- moving a limb
- purposeful movement towards a target
what is it called when you get quickening and shortening of a normal gait pattern in parkinsons?
festination
what does festination look like?
as though the parkinsons patient is in a rush but it is actually a very insufficient way of moving
define bradykinesia.
slowness of movement
what are the 4 consequences of bradykinesia
- mask like face
- loss of arm swing
- festination
- difficulty initiating and stopping an action (eg starting to walk or turning a corner)
