Gait And Cerebellar Function

Question 1

Referred to as reeling gait with wide base, unsteadiness, irregularity of steps and lateral veering.

Answer 1

Cerebellar gait

Question 2

The principal features of this gait are the brusqueness of movement of the legs and stamping of the feet

Answer 2

Sensory-ataxic gait

Question 3

The gait pattern is caused by the paralysis of the pretibial and peroneal muscles with resultant inability to dorsiflex the foot

Answer 3

Steppage or Equine gait

Question 4

The features of this gait are diminished arm swing, forward bent torso, short steps, turning en bloc and hesitation in starting to walk

Answer 4

Parkinsoninian gait

Question 5

A severe forward bending of the trunk at the waist that is symptomatic

Answer 5

Camptocormia

Question 6

The gait is characteristic of gluteal muscle weakness

Answer 6

Waddling gait

Question 7

It is an unusual fast tremor of the legs that is present only when the patient stands or exerts force with the legs while seated

Answer 7

Primary Orthostatic Tremor

Question 8

A term used to describe a psychogenic gait disorder in which patients, although unable to either stand or walk, display more or less normal use of their legs while in bed

Answer 8

Astasia-abasia

Question 9

Answer 15

True

Question 16

It is the least evident cerebellar abnormality

Answer 16

Hypotonia

Question 17

T/F: there are 40 times more afferent axons than efferent axons in the various cerebellar pathways.

Answer 17

True

Question 19

Main afferent input to the cerebellum

Answer 19

Mossy fibers

Question 20

T/F: Lesions involving the superior cerebellar peduncle or the dentate nucleus cause the most severe and enduring cerebellar symptoms.

Answer 20

True

Question 21

Rubral tremor is a result of interruption of what structure?

Answer 21

Superior cerebellar peduncle (which only traverses the red nucleus)

Question 22
