Q

Phase of the gait cycle during which the foot is in contact with the ground

A

Stance phase

1
Q

The period between successive points at which the heel of the same foot strikes the ground

A

Gait cycle

2
Q

Phase of the gait cycle that begins when the toes leave the ground

A

Swing phase

3
Q

What are the requirements for locomotion in an upright bipedal position?

A

1) antigravity support of the body
2) stepping
3) maintenance of equilibrium
4) a means of propulsion

4
Q

What are the muscles of greatest importance in maintaining the erect posture?

A

1) erector spinae

2) extensors of hips & knees

5
Q

The rhythm & number of steps per minute

A

Cadence

6
Q

This sign is the clearest indication that the origin of the problem is a loss of proprioceptive sensibility

A

Romberg sign

7
Q

Type of abnormal gait wherein the main feature is a wide base, unsteadiness, irregularity of steps, & lateral veering

A

Cerebellar gait

8
Q

The principle features of this abnormal gait are the brusqueness of movement of the legs & stamping of the feet as the foot is forcibly brought down on the floor (ostensibly to detect the location of the foot as a substitute for proprioception). The most specific feature is that the ataxia is markedly exaggerated when the patient is deprived of visual cues.

A

Gait of sensory ataxia

9
Q

This gait pattern is caused by paralysis of the pretibial & peroneal muscles, with resultant activity to dorsiflex the foot

A

Steppage/ equine/ foot-drop gait

10
Q

Gait pattern wherein the leg tends to rotate outward to describe a semicircle, first away from then toward the trunk (circumduction) & the foot scrapes the floor

A

Hemiplegic gait

11
Q

Gait pattern wherein the legs are extended or slightly bent at the knees & the thighs may be strongly adducted, causing the legs almost to cross as the patient walks (scissors gait)

A

Spastic paraplegic/ paraparetic gait

12
Q

This gait pattern is characterized by involuntary acceleration or hastening (festination). Other stigmata of this gait are diminished or absent arm swing, turning en bloc, hesitation in starting to walk, shuffling, or “freezing” briefly when encountering doorways or other obstacles

A

Parkinsonian gait

13
Q

This gait is characteristic of gluteal muscle weakness seen in progressive muscular dystrophy.

A

Waddling/ gluteal/ Trendelenburg gait

14
Q

Typically the initial & most prominent symptom of normal-pressure hydrocephalus

A

Progressive difficulty in walking
