voluntary muscle contraction

4

where in the body can be affected by a resting tremor?

any area supported by gravity

5

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

6

When will an essential occur?

when there is voluntary muscle contraction

7

either but commonly many different tremors

9

what will an essential tremor make difficult?

- maintaining posture
- moving a limb
- purposeful movement towards a target

10

what is it called when you get quickening and shortening of a normal gait pattern in parkinsons?

festination

11

as though the parkinsons patient is in a rush but it is actually a very insufficient way of moving

12

slowness of movement

13

- mask like face
