ms 6 - neuro 2

Question 1

Dyskinetic mvmt disorder

Answer 1

= involuntary, sustained muscle contractions that cause twisting and repetitive movemtns or abnormal postures
dystonia, athetosis, chorea

Question 2

A. Dystonia

Answer 2

– INVOLUNTARY, SUSTAINED= ^, bought on by voluntary mvmts + over flow into muscles – can be painful ENVORNOMENTAL OR GENETIC

Question 3

B. Athetosi

Answer 3

– INVOLUNTARY, SLOW, CONVULTED, WRITHING of hands, fingers, feet and toes
- Affects BG – corpus striatum = resp. 4 mvmts by motivation eg perform or supress. Due to intranatal asphyxia or neonatal jaundice

Question 4

1. Chorea

Answer 4

= QUICK, INVOLUTANRY – HANDS & FEET – excessive dopamine affects BG function

Question 5

Other neuro disorders

Answer 5

tremor
ataxiaassosiated reaction
pathological patterns

Question 6

Tremor:

Answer 6

involuntary mvmt which can be stimulated during quiet play, fine coordinated activity (eg threading small beads), when upset/hungry/anxious or with sustained postural control (static hold with UL at 90˚ flx, arm ext and supination and hold for as long as possiple) or at rest.
Can be either intention tremor (when doing something on purpose), fine regular tremor or irregular/jerky tremo
- Intention tremor= cerebellar lesion
- Resting tremor = BG lesion

Question 7

Ataxia =

Answer 7

inability to control muscle contracture for voluntary movement – force, speed, direction, range, rhythm. OVERSHOOT OR UNDERSHOOT – CEREBELLAR DYSFUNCTION

Question 8

Pathological patterns

Answer 8

– certain postures/mvmts charastic to certain neuro impairments
Stim = body/head posture (prop), head mvmt (vestib, vision), body contact (prop and tactile)
Eg thumb in palm, scissor legs

Question 9

Associated reaction

Answer 9

• Associated reactions are involuntary movement that is not due to a stretch or nociceptive reflex – stimulus is the amount of effort being expended with failure to complete motor activity – SEEN AS SOMETHING DIIFCIUTL
  EG TONGUE ROLLING, LIMB TURNING
  Synkinesis (mirror movements) normally observed about the age of 2 ‐2.5y. Some associated reactions such as tongue rolling and limb turning can persist to early teens.
