Flashcards in Gait and Cerebellar Dysfunction Deck (21):
1

What can cause a person to have an abnormal stance prior to walking?

- DCP lesion
- Cerebellar lesion

2

Broad-based Ataxic Gait
- What is it?
- What is it seen in?

Feet are spread wide apart with a unsteady gait.

- Seen with lesions of DCP or sensory nerves or cerebellar lesions

3

Hemiplegic Gait
- What is it?
- What is it seen in?

Lower limb is stiffly extended and swung out and circumducted while upper limb is flexed at the elbow and wrist

- Seen in stroke pts

4

Tabetic Gait
- What is it?
- What is it seen in?

Foot slapping gait to compensate for impaired sensation.

- Seen in neurosyphilis or severe neuropathy

5

Steppage Gait
- What is it?
- What is it seen in?

Foot drop is found so the hip flexes higher to prevent tripping over the foot.

- Seen in peroneal nerve lesions that lead to foot drop

6

Waddling Gait
- What is it?
- What is it seen in?

Weak pelvic/hip muscles cannot support the body on one leg so swaying occurs in the opposite direction to the raised foot to compensate.

- Seen in myopathy

7

Scissors Gait
- What is it?
- What is it seen in?

Tightness and spasms in adductor muscles of thighs forces the knees together when walking.

- Due to CST lesions as in cerebral palsy/MS that lead to spastic paraparesis

8

Parkinsonian Gait
- What is it?
- What is it seen in?

Slow, shuffling gait with hunched forward posture.

- Seen in Parkinson's disease

9

What are pupils that are unreactive to light but constrict with the near reflex indicative of?

Argyll-Robertson pupils - indicative of neurosyphilis

10

Rebound

Imbalance of agonist and antagonist muscles that leads to the sudden release of
contracted biceps causes striking the face; triceps
does not “check” this action anymore

11

Hemispheral Syndrome of Cerebellum

Predominantly affects ipsilateral limbs ipsilaterally (kinetic tremor, limb dysmetria, rebound phenomenon)

12

Vermian Syndrome of Cerebellum

Predominantly affects the trunk (truncal unsteadiness with
standing or walking, tremor, postural impairment, gait ataxia)

13

Alcoholic Cerebellar Degeneration

Atrophy of anterior-superior vermis with gait ataxia and lower limb dysmetria.

14

Hemiballismus

Rapid, violent, flinging movements of proximal upper and lower limbs on one side due to a lesion of the contralateral subthalamic nucleus;

15

Dystonia

Continual or sustained painful contraction of muscles, causing
turning and spasms of the limbs or neck, with fixed, unnatural postures.

16

Tic

Brief, semipurposeful, stereotyped, repetitive contractions of groups of muscles

17

Myoclonus

Rapid, shocklike movements of the limbs or body, usually
bilateral, but often asynchronous - due to diffuse encephalopathies

18

Treatments for Essential Tremor

- Beta blockers
- Barbiturates

19

Treatments for Resting Tremor

- Anticholinergics
- L-DOPA
- DOPA agonists

20

Treatments for Choreoathetosis/Hemiballismus

DOPA Antagonists

21

Treatments for Dystonia

- Anticholinergics
- Benzodiazepines
- Botulinum Injections
