PDF - Gait / Movement Flashcards
What provides postural gait control and postural coordination?
- EPS
2. Cerebellum
What is needed to walk in dark?
Sensation, primarily proprioception
What is gate apraxia?
Have all capabilities needed to walk but cannot walk when asked to do so
What is romberg sign?
Can stand readily with feet together but will sway when eyes are closed
- Proprioception not in tact
What is issue if patient has to spread feet to keep balance?
Cerebellar issue
What is broad based ataxic gait, when is it seen?
- Have to spread feet for balance
- Worse on heel toe / straight line
- Can be cerebellar or posterior column dysfunction
What is hemiplegic gait?
- Leg stiff and circumscribed on walking
2. Ipsilateral arm flexed arm and wrist with diminished swing
What is tabetic gait?
- Seen in tabes dorsalis
- Foot slapping gait
- Forcibly planting feet to floor to compensate for decreased sensation
What is steppage gait?
- Seen in foot drop / weak dorsiflexion
- Hip lifted higher than normal to prevent tripping toes
- Toes slowly lowered down first
Cuase foot drop?
- Peroneal nerve
OR - L5 root
What is waddling gait? When seen?
- Seen in myopathies from weak hip muscles
2. Trunk lifted and bent to L when R foot raised
Scissor gait? When seen?
- Advancing limb crosses midline
- Seen in UMN (corticospinal) lesions
- Spastic Adductors are forcing limbs to cross
Parkinsonian gait?
- Slow, shuffling
- Stooped
- Lots of steps on turning
- Decreased arm swing
* Festination of gait: having to lean forward to start then run to catch center of gravity
Function of cerebellum?
Coordinates smoothness and coordination of movements of limbs, eyes, trunk, and voice
Weakness seen in cerebellar lesions?
No
What is dysmetria?
Over or undershooting of target by hand / foot
Where is lesion in cerebellum impacting voice?
Left hemisphere
Which side of body do cerebellar lesions impact?
Ipsilateral
Where do midline cerebellar lesions impact?
The trunk
Non neuro features friedreich’s Ataxia?
- Pes cavus - high arches
- Scoliosis
- Cardiac hypertrophy - arrhythmias
Multiple trinucleotide repeats on chromosome 9?
Friedreich’s ataxia
Type of tremor in familial essential tremor?
Postural: more apparent when arm held out for example
What is athetosis?
Slow, writhing movements of distal limbs
Causes choreoathetosis?
Lesions in caudate
- Seen in huntingtons
Causes hemiballismus?
Lesion in contralateral subthalamic nucleus often from ischemic stroke
Comorbidity tourettes?
ADHD
What is myoclonus?
Rapid, shock live movements of limbs
- Seen in CJD or encephalopathy
Rx essential tremor?
Beta blocker
Rx dystonia?
- Anticholinergics
- Benzos
- Botox
Rx tix, hemiballismus, chorea athetosis?
- Dopamine antagonists
