1

Basal ganglia disorders

  • tremor (usually resting)
  • Hypokinetic
    • rigidity
    • bradykinesia
  • hyperkinetic
    • chorea
    • athetosis = slow, involuntary writhing movements of hands/feet (sometimes arms, legs)
    • akathisia = feelings of restlessness
    • dystonia = simultaneous agonist/antagonist contraction

2

Cerebellar disorders

  • synergy problems (ataxia)
    • dysmetria = lack of coordination
    • dysdidochokinesia = breakdown of quick, repetitive movements
    • decomposition of movement
  • equilibrium problems
  • hypotonioa
  • tremor (usually w/action)
  • nystagmus

3

mnemonic for cerebellar lesions

  • HANDS Tremor:
    • Hypotonia
    • Ataxia/Asynergia
    • Nystagmus
    • Dysarthria
    • Stance and Gait
    • Tremor

4

Indications of positive romberg test

  • romberg test = stand with feet together and close eyes
    • positive = wavering/loss of balance
  1. ==> impaired proprioception @ dorsal column/spinal cord
  2. ==> impaired vestibular fxn
    1. pt. will fall towards the lesion
  3. ==> impaired cerebellar fxn
    1. usually @ vermis or vestibulocerebellar region

5

Testing of CN coordination via rapid speech

  • Lalalalalala - CN 12
  • Papapapapa- CN 7
  • Cacacacaca - CN 10

6

Characteristics of pull test

  • test for postural instability
  • patient stands comfortably, examiner pulls backward and asks patient to try and maintain posture balance
  • abnormal = pts w/extrapyramidal disorders have difficulty maintaining posture and take several steps back

7

Tandem gait examination

  • pt. walks in a straight line, touching toes of back foot to heel of front foot
  • examination to dx ataxia

8

Forced gait tests

  • ask pt. to walk in different ways:
  • on outsides of feet
  • on heels
  • on toes
  • hop on left and right feet

9

Types of abnormal gaits

  • neuropathic gait
    • = high gait to avoid foot drag
    • = peripheral nerve disease
  • myopathic gait
  • hemiparetic gait
    • = swinging gate (circumduction) on affected side
    • + arm tuck + spastic muscle
    • = UMN lesion
  • diplegic/paraparetic gait
    • = swinging gate on both sides
    •  + adducted knees
    • = LMN problem
  • bradykinetic gait
  • choreiform gait = foot drop and steppage
  • ataxic gait
